Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a user participatory design support system in the housing industry, and more particularly, in a housing design, a user and an architectural design contractor cooperate with each other.
The present invention relates to a user-participation-type design support system in the housing industry that can realize user demands.

[0002]

2. Description of the Related Art There is known housing design support software for general users who is involved in house design using a general-purpose personal computer at home or the like. This type of house design support software is provided when a program file is distributed via a communication line such as the Internet or a personal computer communication, or when a CD-R in which a program file of the house design support software is stored.
It is provided to general users by means such as when a storage medium such as OM is distributed.

[0003] Each general user can use a general-purpose personal computer or the like to design an arbitrary house using housing design support software. In this way, when the general user performs the design, the general user is different from the case where the house designer having the specialized knowledge designs, and the main information at the time of designing the house, for example, the specialized information of each part, each material, However, there is little information on house safety and laws and regulations, so the design drawings designed by ordinary customers simply represent the layout desired by the customer in a two-dimensional manner, and it is not necessarily possible to build them. I can not say.

Further, in the above-mentioned housing design support software, information on a design drawing designed by a general user is not provided to a provider of the housing design support software or a house maker, and the design data is owned only by the user. It will be.

[0005] On the other hand, when a designer having specialized knowledge performs a design, a wide variety of "CAD software" is generally used to create a design drawing. Generally, a building is composed of an assembly in which various kinds of components are combined. The components used there, or the state when they are assembled and completed as a building, are expressed in the design drawings by making full use of geometric elements such as lines and arcs.

However, considering the original role of design,
Such drawing work is also important work, but in order to satisfy the desired function and quality in the building to be created, it is necessary to grasp various characteristic information of each part used. Is even more important.

Further, when taking individual parts, in addition to their shapes, materials, mass, volume, specifications, model numbers, manufacturers,
It has various characteristics and information, such as cost, schedule, etc., that cannot be expressed by the shape.

[0008] In the conventional "CAD", a method has been attempted in which a part is provided as an attribute of a part shape (grouped geometric element), but its use is still limited.
In many cases, these depend on the experience of the designer.

For example, a CAD system as a drafting tool, CG, presentation using image processing, word processing, document processing by spreadsheet software, and numerical processing,
The initial use of computers in design activities, including structural calculations, air-conditioning load calculations, etc., often depended on the single use of computational processing, etc., or depended on the capabilities of the designer.

On the other hand, recent advances in information technology have been remarkable. Recently, information collection using networks has been carried out, information analysis by constructing various databases,
Environments related to information technology, such as collaborative design using groupware, suggest that conventional system design techniques will be significantly changed.

Therefore, according to Japanese Patent Application No. 11-236215, an invention relating to a design method using object orientation, a design apparatus using object orientation, and a recording medium recording a design program, which is preferably used for a building such as a building. Has been made.

Here, the aforementioned Japanese Patent Application No. 11-236215 has been disclosed.
Will be described briefly. As an example, a design device (a general-purpose personal computer or the like) is installed in each office of a house maker.
The design device includes an input unit, a unit that performs arithmetic processing, a storage unit, and a transmission / reception unit that communicates with the output unit. On the server side in the business office, there is a device configuration similar to that described above, and various housing support databases are provided. The designer designs a house on a WWW browser by operating various databases via the intranet.

As an output means, for example, in the case of a monitor display, an image for specifying a space is displayed, an image in which a “girder group” is set is displayed, an image for “designation of internal fittings” is displayed, and “new parts (windproof) is displayed. The image of "body difference) addition" is displayed. On the other hand, the input means designates a "unit space", and any of them can be "selected by dialog". In other words, a plurality of persons including the customer can perform input while examining.

For example, a geometric model, a design model of a building, a structural part model of a building, a common term model of a building, constituent elements of a building (design result data), and the like, which are described in detail later, are associated with each other. It is something to choose. The house design support database is composed of each model group.

Here, the geometric model means a rectangular parallelepiped space (rectangular shape and its lines and points), a plurality of rectangular parallelepiped spaces (polygons and its lines and points), a multi-layered polygonal prism space from the input unit space. (Multilayer polygon overlap and line overlap),
This is a model that generates various types of geometric information obtained in each space.

First, the relationship between each part (part) and its aggregate (entire) is modeled. Next, each modeled part (portion) is treated as an "object", and functions, attributes, and relationships are set for each component (portion). Furthermore, an environment (a model sharing environment) in which cooperative work can be performed via a network is formed.

Next, the concept of a model representing the relationship between a building and its parts will be described. The model system of this example is composed of a geometric model that captures the entire building from the shape, and a part model that is arranged in each part of the shape. The part model includes a structural part model, a design part model,
It is set to be configured from three models of the common part model. Here, the relationship between the geometric model and the part model will be schematically described. The geometric model generates all the unit space data of the rectangular parallelepiped space including the two specified diagonal unit spaces, the data of the side surface of the rectangular parallelepiped space, and the data of the four corners of the rectangular parallelepiped space. When a plurality of pieces are generated, data of the outer peripheral side face and the inner side face as the polygonal prism space, and data of the corner as the polygonal prism space are generated.
Further, when the polygonal column space is generated in multiple layers, the data that has already been generated as the polygonal column space is generated so that the relationship between the respective layers can be determined. The part model structures the materials (parts) constituting the building, treats the set parts as data having functions, attributes, and relationships for each part, and forms a so-called object-oriented database. Here, as one of the functions of the set component, a function of “reading a geometric model necessary for operating its own function” is a relationship between the component model and the geometric model.

Further, the detailed description of each of these models and the functions, relationships, and attributes of each part, and the contents of the design procedure of a space object database by treating all of them as a database are described in Japanese Patent Application No. 11-236215. Because of the content,
Here, the description is omitted.

According to the above-mentioned invention, each part and its aggregate in the house design, that is, "part" and "whole" can always be linked and coordinated. In addition, when developing a product for a house, the designer himself / herself can mount a space object database as a design tool on a CAD, a personal computer, a workstation, or the like, thereby performing a design simulation for a newly set component. further,
By adding new parts to the space object database, data can be shared between the development department and the execution department.
Design rules can be supplied as a system. The characteristics of each part can be confirmed on the model, and simulation can be performed based on its attributes. CAD data can be shared, added, and modified easily.

That is, a system can be sequentially created simultaneously with product development, and test and simulation can be performed. The mechanism created by development enables data sharing among multiple departments. Simultaneous simulation of the planning design and the production design makes it possible to verify the consistency between the part and the whole each time. The design rules themselves can be supplied as a system instead of documents or drawings, and there is no need to interpret them. The system can be created sequentially at the same time as the product (part) development, and the development man-hour can be greatly reduced. The space object database can be accessed from any environment and its contents can be added and modified as needed.

Then, the cooperative design on the Internet or the Internet becomes possible.
You can design directly on the homepage.

Also, the designer is required to set the space 2 to be set.
Just by specifying the unit space of the corner, the space and the building members used in this space are also calculated and options are presented, so it is possible to promptly present a concrete design plan to the owner etc. it can. In addition, by storing the selected models as data, we can propose more proactive (customer-inspired) plans, plan in line with the owner's lifestyle, and plan that can respond to anticipated situations. Can be proposed.

As mentioned above, Japanese Patent Application No. Hei 11-236215
According to this, it has become possible to generalize the design method. In other words, if the functions and the like of the parts assumed in the design in advance are incorporated in the program and the conditions are selected based on the guide on the screen while interacting with the computer, the design can be performed even by a layman.

[0024]

When a general user designs using conventional housing design support software, it is impossible to check the planning due to lack of design knowledge and design techniques. It is almost impossible to design in consideration of various laws and regulations, structural safety, material selection, building design, etc., only by expressing the desired layout.

In the budget planning, if conventional housing design support software is used, it is theoretically possible to accumulate necessary parts one after another. Is usually not possible. (Normally, the market price is not the sum of the prices of the necessary parts and materials.) This is because the general user uses a single piece of conventional housing design support software, Since data on the design specifications is not exchanged with the software manufacturer that provides the support software, it is not possible for general users to know the approximate budget because the cost of the designed building is not estimated or estimated. It is possible.

According to Japanese Patent Application No. 11-236215,
When designing a house, by using a design method using object orientation and a design device using object orientation and a recording medium recording a design program, which are preferably used for buildings such as buildings, Generalization can be performed. In other words, if the functions and the like of the parts assumed in the design in advance are incorporated in the program and the conditions are selected based on the guide on the screen while interacting with the computer, the design can be performed even by a layman.

However, in these design support systems, a house maker uses a house design support database (space object database) and installs them in order for a designer who has obtained specialized information to perform the above-described design method. Installed a general-purpose personal computer, etc. as a client at each office of the home maker, connected the server to the client, and connected to the server via the intranet. It is effectively used when designing with. In such a case, the user cannot directly participate in the design work.

The designer meets with the user to make a design that reflects the user's demands as much as possible. However, there are many cases where the design does not meet the demands. Each time, the design contents and specifications are changed, and it is ideal that the designer and the user perform the mutual confirmation work promptly. However, in reality, complicated work is required and is impossible. Therefore, it is difficult to perform the design work immediately corresponding to the user's design request,
There is a problem that user demands are not efficiently reflected in house design.

Since the user's request is not efficiently reflected in the design, the user requests the designer to perform the design again, and the design work performed by the designer is repeated several times. Thus, there is a problem that the design work is inefficient.

Next, if a general user uses only the conventional housing design support software alone, a maker that performs a design and construction of a building called a house maker, or a house maker or software maker that provides house design support software Since the design data of the user is not provided to the side, there is a problem that the request of a large number of users cannot be fed back to the next-generation house design for the house maker or the like.

When a designer receives a request from a user and performs a design, a standard house design plan example is presented to the user. In the example of a house design plan, a standard plan is presented for a user's family structure, generation, site conditions, and the like. There is a problem that it is not a plan example that meets the demands of many users because it is designed in Therefore, the design is naturally changed from the plan example, and the design is repeated many times. Even when the design work is repeated in this way, it is difficult for the designer to perform the design in accordance with all of the user's demands. Persuasion is needed.

As a further problem, when a user requests design and construction from a house maker or an architectural office, etc., the user lacks specialized information related to house construction, and because of the complicated procedures, etc. In many cases, the construction itself relies on housing manufacturers, architectural offices (design specialists), etc. As a result, there is a possibility that sufficient pre-check, inspection, supervision, and site management of the building during design, construction, and after construction may not be performed sufficiently, causing problems such as inadequate construction buildings. There is a fear.

The house maker also provides detailed information on various drawings and other procedures only by presenting a floor plan of the house design to the user (constructor) because necessary information related to house construction is a specialized content. There is a possibility that the explanation cannot be sufficiently provided. Originally, the design documents submitted when submitting a confirmation application for construction,
The designer has presented, disclosed, and provided a sufficient explanation.

However, a user who lacks information and knowledge and tends to rely on a designer may not be able to consider the design document. As a result, most of the procedures are requested by a design expert, and the user may approve the confirmation without confirming the design documents and apply for confirmation. In addition, the design documents are presented to the user and disclosed,
Even if it is explained, it is difficult for a user who has not participated in the design work to judge the right or wrong of the design document.

Further, in the conventional construction work, the design department,
The exchange of information in each department such as the construction department, factory department,
It is performed on documents such as design drawings and execution budget documents. For example, in a factory, not all information required for parts production, such as material components, quantities, and standards, is transmitted from design drawings alone, but the factory section collects and uses parts-related information again. As a result, problems such as an increase in the number of work processes of parts procurement and an assembly production line and a delay in construction period are likely to occur.

Further, the user cannot grasp the completion status or the site management status unless the user inquires of the house maker or goes directly to the site. If the communication between the user and the house maker about these information and the contents of the inspection results is insufficient, there is a problem that leads to troubles during and after the construction.

Next, in the conventional after-sales service after the construction property is delivered, the complaint reception desk handles telephone calls after the construction property is delivered. Lack of efficiency is one of the causes of complaints. Also, in the case where many troubles occur in the building of many users, the house maker will deal with the trouble for each user each time, and as a house maker,
There is a disadvantage that work efficiency is poor.

Accordingly, an object of the present invention is to provide an object-oriented design method, an object-oriented design apparatus, and a user equipped with a recording medium recording a design program, which are preferably used for designing a building such as a building. User participation in the housing industry, by using the business design support database for specifications (space object database), so that users can participate in the design of their own buildings and co-design with the sales and design departments of the housing manufacturer It is to provide a mold design support system.

Another object of the present invention is to provide a housing maker with:
It is an object of the present invention to provide a user participatory design support system in the housing industry that can grasp the needs of many users and provide a user with a recommended housing design plan corresponding to the needs.

A further object of the present invention is to provide a user-participation-type design support system in the housing industry in which a user can receive a presentation of a design document obtained by a detailed design and a detailed explanation from a designer, and can understand technical contents. To provide.

A further object of the present invention is to provide a user participatory design support system in the housing industry for performing a series of house constructions comprehensively managed based on design data.

A further object of the present invention is to use a database relating to construction objects delivered to the user, and to quickly and efficiently increase the efficiency and automation of the construction objects after the delivery, and to perform house management for maintenance management. It is an object of the present invention to provide a user participatory design support system in industry.

[0043]

In order to solve the above-mentioned problems, the present inventors have already invented a design method using object orientation, a design apparatus using object orientation, and a recording medium storing a design program. Japanese Patent Application No. 11-
No. 236215), a business house design support database (SODB: space object database) for a house maker is constructed, and a user uses a general-purpose personal computer or the like connected to a server equipped with a business space object database to access the Internet. Alternatively, the present invention can be achieved by making it possible to perform a general design of user participation while browsing a homepage using a web service provided by an intranet.

Here, the housing maker introduces a business space object database adapted to his / her own business, so that the user can easily obtain an environment in which he can participate in the housing design of the house maker. On the other hand, the housing manufacturer's design department and sales department perform quick and appropriate data check and additional input, and the information can be provided to the user.

That is, the above object is attained in claim 1 of the present invention.
According to the user participatory design support system in the housing industry according to the present invention, a means for providing a home design homepage for the user to browse, and the user performs a rough design of the home with or without a planning area on the homepage. A user-specified area, a request input unit for inputting a user's request in the user-specified area, a connection between the homepage and a design support database previously provided in a server, and the design support database on the homepage. An operating unit, a checking unit that is performed in association with the desired input item input to the user-specified region by operating the design support database, and a notifying unit that notifies a user of a result obtained by the checking unit. ,
Is at least constituted by:

Further, in the above solution, it is more preferable that an integration area for the user to make a rough design of the house is formed on the homepage. Preferably, the checking means is configured to include at least one of site conditions and budget, related laws and regulations, safety as a structure, and various functions as a dwelling. Then, it is preferable to include a post-check correction unit that corrects the inconvenience caused by the check unit and corrects the user-specified area without or with the user's consent.

Further, it is preferable that the integration area includes at least one of a simulation for a budget, setting of various equipment specifications, setting of specifications relating to an exterior, and setting of specifications of each part of a building.

Further, with respect to the schematic design data created based on the user-specified area and the desired input items corrected by the post-check correction means or the notification means,
It is preferable that the homepage has a determination area regarding the conclusion of a contract.

[0049] By making the conditions necessary for the actual design a check item, unlike the case where the user freely and arbitrarily draws a floor plan, these can be constructed substantially for the user, and This makes it possible to easily design a house that directly reflects the needs of the user. Furthermore, the design work time until the contract is concluded, which is performed when a design satisfactory to the user is obtained, can be reduced as compared with the case where only the designer performs the design.

Further, in the case where "No" is determined in the contract decision area, the user's request contents and the tendency of "No" are grasped, and a needs trend database construction means associated with the schematic design data is stored in advance in the server. It is preferable to include a design support database reconstructing unit that is updated and associated with the provided design support database and the needs trend database.

In the case where the contract is not concluded, revision elements are added or corrected to the outline design data, the content of the user's request and its tendency are grasped, and a recommended plan is created according to the budget. Housing manufacturers always build a needs trend database that responds to user needs trends.
In addition, the needs trend database is fed back to the business space object database. Further, there are provided a design means for a recommended design plan performed by a design expert in association with the needs trend database, a means for presenting the recommended design plan on the homepage, and a schematic design means for a user to associate with the recommended design plan. It is suitable. Using the business space object database reconstructed in this way, it becomes possible to provide users with a housing design means as a new product based on market trends.

Further, when "concluded" is set in the contract decision area, the detailed design means performed by a design expert in association with the schematic design data, the building means associated with the detailed design data, It is preferable to provide at least one of the following: maintenance means performed for the construction article constructed by the means.

Further, the detailed design means includes a design document output means associated with the detailed design data, a confirmation application means for construction performed using the design document,

After going through the necessary check items in the outline design,
The building components (design result data) and their history data are accumulated, and after the contract is concluded, the design specialist uses the business space object database to check data and create additional data for creating design documents. , Output a design drawing, a quote, etc., and present the design book, the quote to the user.

Further, since the user participates in the schematic design, it is possible to sufficiently grasp and understand the design contents at the time of receiving the explanation of the design document. Therefore, it is possible to prevent troubles due to inadequacy of the building during and after construction.

The construction means includes: an output means for an execution budget created in association with the detailed design data; an order means for factory parts and on-site parts associated with the detailed design data; Comprising: at least one means of site management means of the completion status associated therewith, inspection means of the building associated with the detailed design data, and delivery means of the construction property associated with the detailed design data It is good to configure.

Further, the means for ordering factory parts may be configured to include at least one of material procurement, part assembly production, schedule management related to part production, and delivery management of completed parts performed by the department in charge of the distribution business.

Further, the construction inspection means includes: completion information indicating completion of construction related to the completion status associated with the detailed design data; completion inspection result information of the construction associated with the detailed design data; It may be configured to include at least the completion information and output means for notifying the user of the building situation data obtained from the completion inspection result information.

The maintenance means includes: a construction property database construction means associated with the construction property data accumulated by the user requirement input means; and the homepage and the construction property database pre-installed on a server. It is at least composed of a means for connecting and operating the construction article database on the homepage, and a maintenance service operation for the construction article associated with the construction article database.

As described above, based on the design data, the user, the design department, the sales department, the builder, the logistics department, and the factory mutually participate to perform a series of construction work from design to construction and delivery. It becomes possible to manage. As a result, the work of each department can be made more efficient by cooperating with each other based on the design data. In addition, since the building status information is always released via the communication line, users can easily grasp the contents of the completion and know the inspection results by means such as browsing the homepage, etc. Troubles between home and house maker can be prevented beforehand.

And a transmission / reception unit that transmits / receives data to / from the external device through the communication unit. Each means used in the design device S is a design device S
It is needless to say that a device such as a general-purpose personal computer and other peripheral devices can be used.

The input means 10 instructs the arithmetic means 12 and the like. The arithmetic means 12 obtains various data or necessary programs from the storage means 14 according to a command from the input device, and executes necessary arithmetic operations. Is what you do. The program file of the design engine 12 is stored in the ROM or the HDD 14 in advance. In addition, a house design object, a house parts master, a design model rule base group (composed of a beam arrangement rule base, a column rule base, and a fixture rule base) and a program file of a rule base engine which is a central processing unit of the rule base are also prepared in advance. It is stored in the ROM or the HDD 14. Input means 1
From 0, an input instruction is given for, for example, “pillar”. Along with this input instruction, the program data of the design engine 12, the data stored in each database, and the program data of the rule base engine are loaded into the RAM,
Calculation processing is performed between PUs. In this example, column information is extracted from the column arrangement rule base, and a check process of the column position, thickness, and the like is performed. If a correction is necessary for the “pillar” input by the user, measures such as displaying a warning message to the user will be taken. Some appropriate "pillar" information for prompting a proper input instruction may be presented together with the warning message. Then, the calculation result is output to the output unit 16. The output means 16 includes a printer 16a (a dot printer, a laser printer, a liquid crystal printer, etc.) which performs display on an electronic / mechanical display device for visual observation of a CRT or a liquid crystal screen as a monitor, and outputs to paper or other media.

It is configured to input and output data with the outside via the WW server 38 and the like. In addition, an Applet 30 for driving data in HTML (or XML) language, JAVA language, or the like is introduced.

As described above, the network language (for example, J
The design engine 33 is implemented by using the AVA language) and the distributed object environments 31 and 32 together. At this time, each of the design model components 35 and 36 to be executed is an object class, and can be reused or differentially designed for normal design expansion, so that the number of development steps can be greatly reduced. Is done. Thus, in this example,
The provision of an environment for easily searching on the Internet uses software as a language and uses JAVA as a language, which is sufficient.

In FIG. 2, for example, the various databases 36 described above are stored on the server side, and the database is accessed and displayed on a display at a plurality of locations, for example, between the sales department, the design department, and the user. It is possible to present the design simulation on the monitor while explaining to the user together with the voice while watching the state that has been performed. In this way, the department specializing in architecture, including structural design, the sales department, which is familiar with selling prices, etc., and the customer who is the buyer, simultaneously conduct concrete and visual design while repeating satisfactory questions and answers. It is possible to configure so that it can be performed.

Next, the input means 1 in the design device S
The output means 16 will be described with reference to the work procedure of the client-server system shown in FIG. For example, in the case of a monitor output, a design support homepage 39 is displayed on a WWW browser 39a. The user selects “room name” on the WWW browser screen, and specifies “space” on the CAD browser screen 39b. Similarly, all "room names" for each floor
Enter On the server side, these input information are received, the program data of the design engine and the rule base engine stored in the ROM or the HDD 14, and the data stored in various databases are loaded into the RAM, and the arithmetic processing is performed between the CPU and the CPU. Then, various databases are activated. Therefore, all geometric models are generated based on the designation of “space” from the user. Various checks relating to the "room name" and the size of the "space" are performed, and the planar shape is displayed on the browser. Therefore, the plane shape of each floor is displayed on the user (client) side.

Next, on the user (client) side, C
For the plane shape on the AD browser screen, the specifications of facilities for each building are selected on the WWW browser screen. On the server side, the geometric model and the part model operate with respect to the specified specification, necessary parts and members are set, and the amount is calculated. For all parts / members, multiplication is performed based on the market unit price or the contractor unit price. Therefore, the estimated amount is calculated, and the estimated amount is displayed on the user (client) side.

Next, on the user (client) side, required conditions such as living conditions, design conditions, site conditions and the like are input.
On the server side, these requirements are analyzed, and the plan closest to the condition is retrieved from the accumulated plan collection. For the searched plan, the unit price at the time of registration is corrected to the current unit price, and the estimated amount is calculated. At this stage, on the user (client) side, the corresponding plan is displayed on the CAD browser, and the estimated amount is displayed on the WWW browser screen.

FIG. 14 is a flowchart showing the operation procedure of the server / client system described above in detail. In step 1, the user (client) specifies a room space for the reference layer (first floor). After all the room spaces in the reference layer are designated, the room space in the arbitrary layer (the second floor, the third floor,..., Etc.) is designated in the same manner as the room space in the reference layer.

In step 2, as shown at A-1 in FIG. 14, the assumed room space is placed on the plane unit space mesh at the diagonal position of the unit space, that is, at the corner space portion (star mark and arrow in the figure). Specify by. As an example of the designation operation, a user (client) or a designer performs the operation while viewing the output image A-1 on the monitor.

In step 3, as shown by A-2 in FIG. 14, data of all unit spaces (stars and dot areas in the drawing) included in the room space are converted from data of the designated unit space. Generate FIG. 15 shows a case where the setting of the room space assumed by the user or the designer has been completed. However, in this example, a reference layer (first floor) and an arbitrary layer (second floor) are illustrated.

The room space image shown in FIG. 15 is output to a user or a designer, for example, on a monitor. In the reference layer (first floor), the room name a, the room name b, the room name c, the room name d, the room name e, the room name f, the room name g, and the room name h are designated and set by the above method. You. The room space in an arbitrary layer (corresponding to the second floor in this example) is set in the same manner. However, on the input screen for designation output to the monitor, only the mesh of the room space is displayed, and data (numerical values such as 137, 136, 135,... Shown in FIG. 15 in this example) are displayed. However, these data (numerical values) are specified in the arithmetic processing performed in the design device S. The output images on the monitor are A-2 and B-2 in the figure. Table 1 shows data (numerical values) of designated locations in the room space set in FIG. For example, in the room name a, the designated location is “1”.
34, 393 ".

[Table 1]

Next, in step 4, A-3 in FIG. 14 is monitored and output, and in the arithmetic processing performed in the design apparatus S, a geometric model as a room space is obtained from all unit space data included in the room space. Is created and these data are stored in a predetermined location.

In step 5, the data of the geometric model as a rectangular parallelepiped generated in step 4 is shown. Table 2 shows data of the generated geometric model as a rectangular parallelepiped for the room space exemplified in FIG. However, in this case, P is the unit length of one mesh, and for example, for the room name a, “size” (vertical * horizontal)
Is “5P * 4P”, and “position” (on coordinates) is “2,
5]. Here, “size” means the number of meshes (grids), and “position” is (0, 0) as a base point (shown in FIG. 15), and coordinates are displayed. In this case, 4
Means the coordinates of the middle left corner. In steps 3 to 5, a geometric model as described above is generated.

[Table 2]

In step 6, each room name part as a design part model reads the data of the corresponding room name from the geometric model, that is, the size (length * width) and the position (on the coordinates). For each room name component, its size is checked for its own room name as “maximum length ≧ vertical length, horizontal size ≧ minimum length”.

In step 7, if the result of the above-mentioned properness check is YES, an instruction to display the shape of the room is given from the "size" and "position" data of the room space as a function of the room name component itself. Here, designation of one room in the reference layer (first floor) is completed. In steps 6 and 7, each room name component in the design component model operates.
On the other hand, if the result of the appropriateness check is NO, a message is displayed in step 7 'indicating that the size of the room name component itself is inappropriate for the room name and the reexamination will be performed as a function of the room name component itself. Instructions. Further, in step 7 '', as an example, a message display “For the designated room name, when the
The range of ≧ vertical and horizontal ≧ 適 切 is appropriate. Please specify again. Is performed, and the process returns to step 2.

In step 8, A-0 in FIG. 14 is monitored and output from the display instruction of the room space shape from step 7. After the completion of the designation of one room by the above operation, the process proceeds to step 9 when another room is designated.

In step 9, the assumed room space is designated adjacent to the room space indicated by A-0 on the monitor. The same operation as in step 2 described above is performed. On the monitor,
B-1 in FIG. 14 is displayed.

In step 10, step 3 described above is performed.
Perform the same operation. B-2 in FIG. 14 is displayed on the monitor.

In step 11, step 4 described above is performed.
Perform the same operation. B-3 in FIG. 14 is displayed on the monitor.

In step 12, step 5 described above is executed.
Perform the same operation. Here, a geometric model in the case where a plurality of rectangular parallelepipeds is combined is generated. Therefore, step 1
In step 3, a geometric model as a polygonal prism is created by combining the created geometric model and a new geometric model, and stored in a predetermined location. On the monitor, B-
4 is displayed.

In step 14, various geometric models as polygonal prisms in the case where a plurality of rectangular parallelepipeds are combined, generated in step 13, are generated. Table 3 shows a part of a generated geometric model as a polygonal column for the room space exemplified in FIG. However, here, not only the reference layer but also an arbitrary layer (the second floor in this example) is displayed. Here, for example, as a part of the geometric model generated from the polygonal prism of the reference layer, data of the outer peripheral surface of the polygonal prism (outer peripheral surface data), data of the inner boundary surface of the polygonal prism (internal boundary surface data) Table 3 shows the data generated as the shape data of the corners on the outer peripheral side surface of the polygonal prism (corner section entrance / exit corner division). (Note that the generation process is described in Japanese Patent Application
236215. Table 3 [1A] Regarding the outer peripheral surface data, the side surface data generated from all the room space data in the above polygonal column is described in Japanese Patent Application No.
In the method based on 236215, the data is divided into the side surface of the outer peripheral portion and the inner side surface, and the data selected as the data of the side surface of the outer peripheral portion is represented. Similarly, as for the internal boundary surface data in Table 3 [1B], the side surface data generated from all the room space data in the polygonal column is used as the data of Japanese Patent Application No. 11-23.
According to the method based on 6215, the data is divided into the side surface of the outer peripheral portion and the inner side surface, and the data selected as the data of the inner side surface is represented. Table 3 [1C] Regarding the exit / entrance corner section of the corner portion, the data of the corner portion generated from all the room space data in the above polygonal column is described in Japanese Patent Application No. Hei 11-236.
In the method based on H.215, the data of the result of the division of the outgoing corner and the ingoing corner is shown. As a result of the designation of the outer peripheral surface data and the inner boundary surface data, FIG. 16 illustrates a polygonal column of a geometric model as a polygonal column generated from the room space data illustrated in FIG. This polygonal prism diagram is output to a user or a designer, for example, on a monitor.

[Table 3]

In step 15, each room name component reads each data (size, position) of the corresponding room name from the geometric model as its own function, and checks for duplication with the room space already specified. .

In step 16, if there is no overlap in the room spaces in the check in step 15, as in step 7 described above, the room name component itself is used as a function of the room size “size” and “position” data. Display its shape,
In FIG. 14, B-0 causes a monitor output. Here, the designation of the second room in the reference layer (first floor) is completed. On the other hand, if there is room space overlap in step 16 ', the position specified as the function of the room name component itself partially overlaps with the already specified position, and the space configuration is impossible. Therefore, an instruction to display a message to re-designate is issued. Further, in step 16 ″, for example, a message display “The specified position overlaps with the already specified position. Check the screen and re-specify.” Is performed, and go to step 9. Return.

In step 17, B-0 in FIG. 14 is monitored and output from the display instruction of the room space shape from step 16. If another room is to be designated, the process proceeds to step 18.

In step 18, a room space is specified to be further adjacent. These room space designating operations include steps 18 to 26. These steps correspond to steps 2 to 8 and steps 9 to 17 described above. By the above-described operation, a plurality of room spaces are designated on the reference layer (first floor).

In step 100, after the room space specification on the reference layer (first floor) is completed, a room space is specified for an arbitrary layer. In step 101, a layer is specified. The specification of the room space in the arbitrary layer (corresponding to the second floor in this example) is the same as the room space specification work of the reference layer, and is performed in step 102.
To step 111 (excluding step 108), and these steps correspond to the above-described steps 2 to 8 and 9 to 17 for specifying the room space in the reference layer.

However, in the case of designating a room space in an arbitrary layer, a geometric model in the case where a plurality of polygonal columns are generated in step 14 is shown. Indicating the positional relationship between the polygon and the outer peripheral surface of the polygon of the arbitrary layer and the outer peripheral surface of the polygon of the reference layer are generated and displayed. Here, FIG. 15 shows a case where the user or the designer himself has assumed the setting of the room space, and FIG. 15 shows a case where all the settings are completed. The data showing the mutual positional relationship between the corners of FIG.
FIG.

[Table 4]

Next, the operation of various component models in a room space set by a user or a designer will be described. As one example, a case where a column model on the outer peripheral surface operates will be described. The outer peripheral column component system assumes that the outer peripheral column is composed of a corner outer peripheral column and an intermediate outer peripheral column. The corner outer peripheral pillar is composed of an outgoing corner and an inner corner, and the intermediate outer peripheral pillar is composed of a pillar affected by others and a pillar not affected by others.

Here, the function of the outer peripheral surface column part will be described. The positional relationship between the corners of the polygonal pillars of the arbitrary layer and the polygonal pillars of the reference layer (data of the midpoint between the corners of the reference layer and the corners) is read. Here, FIG. 18 illustrates “data of a middle part between corners of the reference layer”.

Next, the "data of the intermediate portion between the corners of the reference layer and the corners" read earlier is classified. However, in this case, only the reference layer is targeted. The data of the corner part is group A, the data marked "outside corner" is (A-1), and the data marked "inside corner" is (A-2).
And On the other hand, data classification is performed with the data in the middle part as group B, the data marked as a corner part of an arbitrary layer as (B-1), and the other data as (B-2). Table 5 shows the classified data.

[Table 5]

Next, the function of the corner part outer peripheral surface column part will be described. Read the data of group A that was classified earlier,
With respect to the data in the group of Table 5 (A-1), a search for “outer peripheral pillar” is performed from the component master. Here, it is assumed that the part symbol is “AA1”. On the other hand, for the data in Table 5 (A-2) group, a search for “outer peripheral pillar for corner” is performed from the component master. Here, it is assumed that the part symbol is “AA2”.
The result of the search is set as “data and part symbols” and stored in the “building element file”. Table 6 shows the set data of these “data and part symbols” in the group A data.

[Table 6]

Next, the function of the column part on the outer peripheral surface of the intermediate portion will be described. First, the data of the classified B group is read. Table 5
(B-1) For the data of the group, as a column affected by others, a search for an “intermediate peripheral column” is performed from the component master. Here, it is assumed that the part symbol is “BB1”. On the other hand, based on the relationship between the unit length of the mesh (grid), the position of the fittings, and the like, and the function of the part to be set, the “column allocation” is set for each surface with respect to the data of Table 5 (B-2). Do.
In this case, it is assumed that column parts that are permissible up to 1 / 2P are set, and it is assumed that all outer peripheral surfaces are not affected by fittings.

For example, the corner data [134 to 13]
8] will be described. First, Table 5 (B-
1) For the group data, as a pillar affected by others,
As a result of the search, 134, 135, 136, 137,
138 does not have the corresponding data. Table 5 (B-
1) When there is no data corresponding to the group, the total length of the surface: L = (138-134) * P = 4P, the number of columns: N
= L / 2P-1 = 4P / 2P-1 = 2-1 = 1, and the position of the pillar: N (1) = 134 + 2P = 134 + 2 = 136.

Thus, by the above calculation, the set data of “data and part symbol” in the (B-2) group data is “136-BB2”.

As another example, the corner data [138 to 8]
[42] will be described. First, “BB1” is set for corner data: 202 and 650 as a result of a search performed on the data in the group of Table 5 (B-1) as pillars affected by others. Corner data [138, 2
02, 330, 394, 458, 522, 586, 65
0, 714, 778, 842] and the corner data [138, 202] and the corner data [2
02, 330, 394, 458, 522, 586, 65
0] and corner data [650, 714, 77]
8, 842]. Corner data [13
8, 202], there is no intermediate data, so there is no column part setting. Corner data [202, 330, 394, 458, 522, 586,
650], the total length of the surface: L1 = ｛(6
50-202) / 64｝ * P = 7P, number of pillars: N1 =
7P / 2P-1 = 2.5 → 3, pillar position: N1 (1)
= 202 + (64 * 2) = 330, N1 (3) = 650
− (64 * 2) = 522, N1 (2) = 330 + (64
* 2) = 458 is calculated. Corner data [65
0, 714, 778, 842], the total length of the surface: L2 = {(842-650) / 64} * P = 3
P, number of pillars: N2 = 3P / 2P-1 = 0.5 → 1
Position of pillar: N2 (1) = 650 + (64 * 2) = 778
Is calculated.

The calculation result data as described above is obtained. Here, the retrieved result is stored in the “building element file” as set data of “data and part symbols” in the group B data. Table 7 shows that in group B data,
The set data of these “data and part symbols” is shown.

[Table 7]

As described above, the design result is displayed in the case where the column model on the outer peripheral surface operates. FIG.
9 shows the design results of a part of the column arrangement perspective (reference layer) and a part of the frame diagram (reference layer). FIG.
In the middle, the place where the pillar is arranged is indicated by a bold line, and the pillar part symbol of each place is described. Also, an accumulation list is displayed. In this list, the part symbol and the corresponding quantity, unit price, and amount are specified. The user or the designer proceeds with the design by presenting these design results, an integration table, and the like.

Next, as shown in FIG. 4, in this example, a business-use space object database 40 having each model of a building as a component in a business office is provided on a server.
Communication line (whether wired or wireless), Internet 4
6 through a communication network such as a general-purpose personal computer installed at the user's home 47a on the client side. Note that the client-side design device may be installed not only in the user's home, but also in each of the business offices 47b and the house exhibition hall 47c. In this case, it is possible for the user to go to a sales office or an exhibition hall and perform a schematic design work there.

On the other hand, regarding the server configuration for the office, the design result data 41 obtained by operating the function of the parts,
It is composed of a geometric model 43, a structural part model 44, a design model 45, a common model 42, and the like obtained from the designation of a unit space, and various elements are determined for each content from the viewpoint of functions and attributes. In addition, a detailed description of each of these models and the functions, relationships,
For details on the attributes and on the design procedure using the space object database 40, refer to Japanese Patent Application No. Hei 11-23.
Since the content is the same as that in 6215, the description is omitted here.

Next, a block diagram showing the flow of design data in the user participatory house design support system in FIG. 5 will be described. FIG. 5 is further described with reference to FIGS. The user browses the home design support homepage 39 provided by the present inventors and participates in the home design on the homepage. On the WWW browser, the user performs an outline design work by “selection of product by plan search” 50 or “free design from planning” 60.

The general design “planning” 60 will be described with reference to FIG. The "planning" is configured by check items consisting of specialized information, which is the minimum necessary, using the geometric model generated from the room space designating operation of the above-mentioned steps 1 to 26. R on server side
A design model rule base group stored in the OM or the HDD 14 (a beam arrangement rule base as a part of the function of the beam part, a column arrangement rule base as a part of the function of the column part, a fitting arrangement rule as a part of the function of the fitting part) The rule base data and the program data of the rule base engine are stored in the RAM and are subjected to arithmetic processing with the CPU. Is generated, and a check is performed using various geometric data.

The check items include, for example, a database of the function of the building component group related to the site that determines the design conditions,
A database 61 of parts groups related to budget and budget, a database 62 of functions of building parts groups related to regulations that influence design conditions, a database 63 of functions of building parts groups related to roof shapes that affect design conditions, and influence design conditions. Database of functions of building parts group related to structure 6
4. Other database 65 of general function of building components related to livability. Examples are the above-mentioned steps 6, 7, 7, and 15.
Step 16 is as shown. When the check items are displayed, the user collects information necessary for the design and inputs the information on the browser screen on the homepage. The user can obtain an appropriate check result for the input data at any time from the house maker (server) side.

The check 61 of site conditions and budget will be described. To start planning, it is necessary to confirm site conditions. Depending on the site conditions, the plan may change significantly or the budget may change significantly. Ground surveys, surveys of site boundaries, surveying, and check items such as contact with roads, contact with neighbors, sunshine, and whether ventilation can be obtained are listed. For example, when the ground reinforcement work is added, or the main pipe of water supply and drainage is very far away, outdoor water supply and drainage work may be added. In addition, in principle, drainage such as making the site higher than roads is taken into consideration, ground reinforcement work for soft ground, embankment, pile driving, securing of cliffs, and other preventive measures may be taken. At that time, it is checked whether or not a building that meets the budget is possible. In order to check such items, it is necessary to set the entire site and various parts constituting the site, and to construct an object-oriented database as its own function.

Checks 62 relating to related laws and regulations include “Building Standards Law”, “Building Standards Law Enforcement Order”, “Architect Law”,
There are many laws and regulations on buildings and sites, such as the "City Planning Act" and the "Road Act". It is easier for users to judge the success or failure of laws and regulations when they are provided by a housing design support system based on a database than when they are described in writing or verbally. It becomes possible. As an example of a legal regulation, it may not be possible to build a house in the area where the site is applicable. For example, a house should not be built in the urbanization control area in principle. On the other hand, in an urbanized area, a restricted area is specified, and the use, height, and size of a building built for each area are limited. Such information is stored in the database of the server as its own function of the site, and the user investigates the site conditions and the like and performs an input operation according to the input items without special knowledge about the law.
The input data is automatically checked, and the user is notified of the check result.

In addition, regulations on the size of a house (building rate,
Floor area ratio), restrictions on the height and shape of the house (restriction of diagonal lines and shading), restrictions on the structure and materials of the house (fire prevention area, semi-fire prevention area), restrictions on lighting of living rooms (lighting area), restrictions from neighboring houses (Distance preservation, blindfold). Regarding the contents related to these laws and regulations, the corresponding site, various parts constituting the site, the building, various parts constituting the building, etc., automatically perform check processing as their own functions in response to input data from the user.

Regarding the check 63 for the consistency with the roof shape, the roof shape is greatly affected by the design, construction method, structure, and the material used of the whole building. In addition, the roof shape often serves as a symbol of the building, and a variety of three-dimensional shapes are often seen because it greatly affects the design. In order to perform the check, a geometric model related to the three-dimensional roof shape is appropriately generated, and the function of the building component group related to the roof shape is operated using the geometric model, and the check is performed.

Next, regarding the safety 64 as a structure, an aggregate of each room space assumed by a designer or a user becomes a space of the whole building. And then the security of each part of the building. For the safety of the entire building, confirm that it is structurally mechanically safe as a structure (it is safe for all forces acting on the entire building), and also check compliance with regulations. It is. Depending on the situation, it is possible to provide a house with a more secure and strong driving structure by providing a safety standard line unique to the house maker, which is even stricter than the related laws and regulations.

In the function check 65 as a house, various functions for one room space assumed by a designer or a user are checked, and functions related to a plurality of room spaces are checked. Functions for one room space include: size for use, function and size and position of fittings for lighting and ventilation, function and size and position of fittings for entering and exiting, arrangement of other various equipment, And check the operation procedure. The functions for multiple room spaces are horizontal and
Checks the flow lines between rooms in both vertical directions, the arrangement of fittings along the flow lines, the arrangement of equipment along the flow lines, equipment piping such as electricity, gas, air conditioning, water supply and drainage, compliance with regulations, etc. . For this purpose, the function of the building component group relating to the livability is activated and a check is performed.

As a result of the above-mentioned check, not only a notification to the user side but also a display (illustration / drawing) of contents closest to the user's request and conforming to various regulations may be made.

After the above check items, “accumulation” 70 is performed as shown in FIG. A simulation 71 for the budget is performed based on the design result obtained by “planning” 60. Further, electric equipment, hot water supply equipment, cooling / heating equipment, and the like are set and integrated by setting 72 of various equipment specifications. In the specification 73 about the exterior, the exterior fence, planting,
Parking spaces, gates, drains, etc. are set and integrated. Further, in the specification 74 of each part of the building, materials such as floors, walls, ceilings, and fittings of each room are set and integrated. Here, since the material corresponding to each setting item is determined, the cost is automatically estimated. The check items in the “integration” are also items that show user preferences and preferences,
In the "planning" 60, the cost added more than necessary to the minimum cost is shown. Depending on the budget, the items set in the “accumulation” 70 items are reviewed and the rough design is performed while narrowing down to the budget desired by the user.

Next, referring to FIG. 8, as described above, the general design “planning” 60 is performed by the user, and the “integration” 70 is performed when the check is completed according to each check item. Schematic design data obtained by these schematic design operations is accumulated 80.

Next, a description will be given with reference to FIG. Through the above operation, the outline design data 75 is obtained, and the design expert having the specialized knowledge performs addition / modification 90 by revising new elements and existing elements. As a result, on the server side, the design data is accumulated 91, the content of the user's request and its tendency are grasped 92, and the marketing analysis 93 is performed. The marketing analysis presents a recommended design plan according to the budget, simulates the budget and planning, and feeds the resulting data back to build a new space object database. Is updated 94. Here, we ’ll talk about the recommended design plans, including user ’s family structure, budget plan,
There are various types of houses desired by users depending on their lifestyles and the like. For example, a user who lives in a local city area and a user who lives in an urban area generally have different desires such as a two-story or a three-story building and a basement depending on the land area owned by the user. Therefore, a variety of design plans in which user's wishes are considered in advance are required.
By presenting various recommended design plans for such needs of a large number of users, it becomes easier for the users to make a rough design.

On the other hand, addition based on the schematic design data 75
Based on the design data corrected 90, the design specialist performs a drawing process 95 and various form processes 96 to create a design document and an estimate 97. The design document 52 created and output by the above operation is presented to the user and disclosed.

As described above, based on the schematic design data 75 reflecting the user's request, each operation 90 such as additional correction is performed, and the presentation 94 of the recommended design plan or the design book 52 is presented.

Next, FIG. 10 shows a schematic description of the data division in the business space object database 40, particularly in the entire flow from when the user participates in the design to when the construction is delivered to the user. I have.

FIG. 11 is a work flow chart in FIG. The user makes a rough design using the business space object database 40 and further contracts 1
00 is established, a designer having specialized knowledge performs detailed design 104 based on the schematic design data 75 by additional correction or the like, and as a result, creates a design document, a quote, etc. 105
Then, the work flow from presentation to the user, disclosure, and explanation is schematically shown.

When the contract 100 is not established,
The designer adds / modifies the outline design data 101 and grasps 102 the needs of the user. Therefore, it is possible to create a recommended plan 103 for a house design, and these recommended plans are used for updating 94 of a “product selection by plan search” screen on a homepage for performing a schematic design.

The design document 52 created here includes a plan view, an elevation view, a layout drawing, a site survey drawing, a quotation sheet, a structural drawing, an equipment drawing, a plumbing piping diagram, an electric wiring diagram, and a wall volume. There is a statement. The user receives the explanation of these design documents from the designer, confirms and approves. In this case, since the user has participated in the schematic design in advance, it is easy to understand the meaning of the design document.

Next, referring to FIG. 12, a general description of the entire house design support system from design to delivery of a construction to a user and maintenance of the construction property will be described. Further, the work flow of the entire system will be described with reference to FIG. As described above, when the user 51 participates in the design in the schematic design, the design department 14
2. Cooperative design with the sales department 141 is possible.

If the contract 100 is not established, the needs of the user are grasped as described above and the data is accumulated, thereby constructing the needs trend database 121.
Further, the business space object database is reconstructed 120 using the needs trend database. The reconstruction item is “creation of geometric model and part model” 120
a, “Register with parts master” 120b, “Simulate new parts” 120c, “Port to business” 120d
Consists of items. Therefore, it is possible to present a design recommendation plan corresponding to the user's needs, and these can update the “product selection by plan search” 94 for performing a schematic design of the design support homepage.

On the other hand, after the contract 100 is concluded, the designer adds the detailed design 1
04 is performed. The design book 52 is created based on the detailed design data 130 and presented to the user. By participating in the design, the user can understand the professional and technical contents described in the design document and confirm and judge the design document. Submit the design documents confirmed and accepted by the user to the government office and apply for construction confirmation.

Based on the detailed design data 130, the designer can perform accurate integration. If there is no problem with the design documents, the user enters into a contract with the contractor, and when the confirmation application is received, the user enters the contract.
Is started.

The designer submits the design document 52 to the builder,
Further, the detailed design data 130 also includes parts data, member data, etc., and when the input is started, an execution budget is created based on the detailed design data 130, and ordering of parts and the like 1
