Description

The present invention relates to a method for manufacturing an inner sole to be mounted as an insole for shoes.

Conventionally, as an inner sole (also referred to as a sole plate or a corrective insole) to be attached to the inside of a shoe, there is one provided with a convex portion for lifting a specific part of the sole of the foot. Such a convex portion is often sold as a so-called ready-made product by manufacturing its height or width dimension based on the shape of the sole of an average person (see, for example, Patent Document 1).

On the other hand, inner soles are beginning to be widely used as therapeutic tools in medicine today, and not ready-made products but fully custom (made-to-order) products tailored to specific people are being manufactured. In such a custom-made inner sole manufacturing method, face-to-face counseling with a technician (a doctor or a person who works according to the instructions of a doctor, etc.), measurement of the sole, and molding of the sole are performed. Needs. In addition, based on this measured and molded user's static foot shape (foot shape in standing, lying, sitting, etc.), the inner sole that is made according to the foot shape is still in the world. And it can be said that it is mainstream in Japan as well.

Japanese Unexamined Patent Publication No. 2008-62005

Since the custom-made manufacturing method is a face-to-face type, it can be manufactured only in a specific area where a technician opens, and there is a difference in service in each area. In addition, because it is a face-to-face type, its rarity increases, and in many cases it becomes difficult to obtain it due to price problems due to soaring prices, which also causes service disparities.

In addition, the custom-made inner sole produced according to the static foot pattern described above not only inhibits the movement of the foot, but also impairs the whole body movement that spreads from the foot, thereby inducing pain and the like. As a result, there are many cases in which health is impaired.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a method for manufacturing an inner sole for manufacturing a custom-made inner sole without the need for face-to-face contact with an engineer. be.

In order to solve the above-mentioned problems, the present invention is a method for manufacturing an inner sole that is used as an insole for shoes and is custom-made according to the condition of the foot of the user, and expresses the movement of the user. It is characterized in that the shape of the convex portion provided on the inner sole is determined based on the operation data as electronic data.

Further, the operation data may be a continuous comprehensive operation data in which a plurality of operations are mixed.

Further, the motion data may be one or a combination of one or more of one-leg balance data, stepping data, walking data, side step data, and peculiar motion data.

On the other hand, based on the foot skeletal data obtained from the skeletal information of the user's foot, the foot size is measured from the shapes of the protruding parts and joints of the bones of the user's foot, and the foot size data is independent. It is characterized in that the foot size of the portion of the foot where the bone does not protrude is calculated by using a unique statistical model derived by multivariate analysis as a variable.

It is also possible to calculate the length from the heel of the foot to the trailing edge of the ball of the toe.

Further, the shape of the inner sole may be partially changed based on the interview data which is information on the position of the octopus on the foot, the type of trouble, and the painful part of the body.

Furthermore, the motion data, the foot skeleton data, or the interview data may be acquired through an internet line.

The method for manufacturing an inner sole according to the present invention is used as an insole for shoes, and is used for an inner sole manufactured to be made to order according to the shape of the foot of the user and the state of dynamic movement. Operation data (mainly comprehensive operation data (continuous operation data in which a plurality of operations are mixed)) as electronic data expressing the user's operation is used. Further, as a modified method, the inner sole is based on any one of five types of modified motion data consisting of one-leg balance data, stepping data, walking data, side step data, and peculiar motion data, or a combination of two or more. Since the shape of the convex part to be provided is determined, it is not necessary to meet with a technician based on various electronic data transmitted through a communication line such as the Internet, and it is not a static body but dynamic. It is possible to manufacture a custom-made inner sole that is superior to the conventional one and can be used for various physical conditions.
In addition, based on the foot skeletal data obtained from the skeletal information of the user's foot, the foot size is measured from the shapes of the protruding parts and joints of the bones of the user's foot, and the foot size data is independent. Since the foot size of the part of the foot where the bone does not protrude is calculated using the original statistical model derived by multivariate analysis as a variable, it is also transmitted through a communication line such as the Internet. Based on various electronic data, it is possible to manufacture a custom-made inner sole without the need for face-to-face contact with a technician.
These can produce the following three excellent effects.

(Correction of service disparity)
Currently, depending on the region, there are disparities in people who cannot obtain inner soles and who cannot benefit from them without knowing the existence of inner soles. The root of the disparity is face-to-face manufacturing, and by establishing a non-face-to-face manufacturing method (business model) by the present invention, not only in Japan but also for people all over the world who are suffering from physical troubles and sports performance. Technology can be provided and service disparities will be corrected.

(Improved quality of custom-made inner sole)
The static foot shape data acquired by 3D scanners, which have been widely used in recent years, is the user's static foot shape (foot type in a static standing position, lying position, and sitting position), and is in motion. It has been kinematically and anatomically clarified that the shape is completely different from the foot shape. Rather, the foot is constantly deformed during movement according to the position where the load is applied, the shape of the floor surface, etc., and this deforming foot function is the basis of such excellent human walking ability. It is made up. Therefore, it is difficult to manufacture an optimum inner sole that matches the dynamic foot and physical conditions such as walking and sports with the inner sole mainly produced by this static foot shape data. In the present invention, it is possible to determine the shape of the convex portion provided on the custom-made inner sole based on the dynamic motion data that can be exchanged electronically, which is difficult with the conventional manufacturing method. It will be possible to provide dynamic feet and inner soles that match the physical condition to people all over the world far away.

(Lower price of custom-made inner soles and promotion of social penetration of custom-made inner soles manufactured from medically more rational ideas. Contribution to preventive medicine)
Since it is a face-to-face type, the price of inner soles has soared, and it has been limited to purchase by specific wealthy people or to be manufactured using Japan's medical insurance system. Lower prices are essential for more people to benefit from bespoke inner soles. In addition, due to the nature of medical insurance, it is difficult to make an inner sole from the viewpoint of preventive medicine because the insurance is applied only after the diagnosis is given. Preventive medical tools that do not go through medical insurance are available because of the pain caused by poor physical movements, the characteristic malfunctions that cause injuries in sports, and the fact that they occur before the diagnosis is given at medical institutions. It's very important. It can be said that the present invention is a novel invention that accelerates the promotion of health at the feet and can greatly contribute to society.

It is a schematic diagram explaining a body center of gravity and a floor reaction force. It is a schematic diagram which shows the movement locus of a COP and a body center of gravity. It is a single unit view of the inner sole which concerns on embodiment of this invention, (A) is a plan view, (B) is a right side view of (A). It is an enlarged view of the X part of FIG. It is a plan view of a human foot bone. It is a schematic diagram which shows the positional relationship between a person's foot bone and the 1st to 5th convex portions in a plan view.

All the movements that a person performs on a daily basis are movements that control the center of gravity 26 of the body. COP (Center of Pressure) is important in terms of biomechanics in order to control the center of gravity 26 of the body. First, this COP will be briefly described. In addition, in FIG. 1, for the purpose of facilitating the visual understanding of the relationship between the body center of gravity and COP in a human standing position, a simulated body such as a robot with the upper body removed is placed on an object having a shape close to a semi-elliptical shape. Indicates a stationary state.

As shown in FIG. 1, the force W1 acting in the direction of gravity from the human body center of gravity 26 is transmitted to the foot 25 via the simulated hip joint 22, the simulated knee joint 23, and the simulated ankle joint 24, and is transmitted from the foot 25 to the sole of the foot. Acts on the floor through the object of. On the other hand, a reaction force (hereinafter referred to as a floor reaction force W2) received from the floor via an object on the sole of the foot is generated on the entire sole of the foot 25.

COP is widely used in scientific calculations as the starting point of a combined vector (floor reaction force W2) of forces acting on the entire contact surface between the sole of the foot and an object. Then, the movement of each joint of the whole body including the movement of the center of gravity of the body is physically determined by the magnitude and direction of the floor reaction force W2 generated from this COP. The ideal COP movement trajectory during walking is indicated by a line Y drawn on the foot LF and LR in FIG. By optimizing the COP movement trajectory Y, which differs between individuals, it is possible not only to improve walking style and pain, but also to improve sports performance.

In addition, most COPs of sports and daily movements occur from the heel of the foot or the vicinity of the heel (hereinafter, COP starting point), and the end (COP ending point) is often the toe part. For example, in normal walking, it can be said that it is ideal that the ground is touched from the heel and the part between the mother toe and the two toes is the COP end point. In addition, it can be said that it is ideal that the medial part of the hallux is the end point of the COP in the foot (usually the right foot) distal to the Darget during the golf swing. In this way, the strength and direction of kicking is determined by which toe the end point of the COP is near, or which specific part of the toe, and the force generated by this determines the direction and speed of the center of gravity of the body. And the movement of the body is formed.

Anatomically and kinematically, it is most efficient that the end point of COP is near the hallux. The reason is that the hallux metatarsophalangeal bone 18a, hallux proximal phalanx 19a, and hallux distal phalanx 20a are larger than those of other fingers, and unlike other fingers, the arrangement of muscles that function independently of the hallux. Have, etc. In addition, setting an inappropriate site as the COP end point not only causes deterioration of sports performance, but also causes disability and pain in all movements including walking.

In addition, in humans who walk on two legs, the difference in kicking force between the left and right feet caused by the position of the COP end point or the difference in the movement speed of the COP causes twisting to the entire lower limbs, pelvis, and trunk. It has an impact and is also becoming a social problem, leading to various disorders such as pain.

By guiding the COP end point to a specific part near the hallux, the kicking force at a specific part near the hallux can be improved, or by increasing or decreasing the kicking force at the left and right feet, the kicking force can be further increased. It is possible to create a movement suitable for the purpose, and it can be said that the new point is to install the convex part mainly around the forefoot part (near the finger).

3A and 3B are inner soles 30 according to an embodiment of the present invention, in which FIG. 3A is a plan view and FIG. 3B is a right side view of FIG. 3A. Further, FIG. 4 is an enlarged view of a portion X in FIG. 3 (A). Further, FIG. 5 is a plan view of the metatarsal bone, and FIG. 6 is a schematic view showing the positional relationship between the human foot bone and the first to fifth convex portions in a plan view.

The inner sole 30 shown in FIG. 3 is for the right foot, and the one for the left foot has a symmetrical configuration. Therefore, in the following description, the inner sole 30 for the right foot will be described, and the description for the left foot will be omitted. If a strict comparison is made, the shape of the left foot and the right foot will be asymmetrical depending on the user (because it is necessary to correct the COP movement trajectory caused by the variation in the left and right soles). Assuming that it is within the range of individual differences, we will proceed with the explanation assuming that it is symmetrical.
Further, the inner sole referred to in the present invention is not only used by the user separately attached to the finished shoe, but also a removable inner sole provided in advance at the manufacturing stage and sewn on the shoe. Inner sole is also included.

As shown in FIG. 3A, the inner sole 30 is formed in a shape close to the outer shape (insole shape) that matches the inside of the shoe, and has six regions according to the region lines L1, L2, and L3 when viewed from above. It is divided into. The division of the region lines L1, L2, L3 and the regions A to E is determined based on the structure of the human footbone 1 as shown in FIG.

The human footbone 1 can be divided into three regions A, B, and C in the anterior-posterior direction. Specifically, forefoot A (1st to 5th metatarsals 18, 1st to 5th toes 19 (1st to 5th are the 1st (mother toe), 2nd (toe), respectively), It refers to the 3rd (middle toe), 4th (ring toe), and 5th (small toe). Position), metatarsal bone B (composed of wedge-shaped bones 11, 12, 13, cubic bone 14, boat-shaped bone 15: between Chopard joint and Lisfranc joint), and hindfoot part C (heelbone 17, It is composed of the metatarsal bone 16 (proximal to the Chopar joint). The area lines L1 and L2 are lines that roughly divide these areas A, B, and C.

Further, one region line L3 is drawn substantially perpendicular to the paper surface of FIG. 5 connecting the apex of the second toe to the most protruding portion of the calcaneus, and two regions (inner portion D and outer portion E) are drawn on the left and right sides of the region line L3. ) Is divided.
The positions of the area lines L1 to L3 shown in FIG. 5 correspond to the positions of the area lines L1 to L3 shown in FIG. 3 (A).

The inner sole 30 is molded according to the internal shape of the shoe and is composed of a sole having a certain thickness and a group of convex portions 40 on the inner forefoot that protrude upward from the upper surface 31b of the sole 31. There is. Further, as shown in FIG. 4, the medial forefoot convex portion group 40 has five convex portions (first convex portion 41,) in the region of the forefoot portion A and the medial portion D partitioned by the region lines L1 and L3. It is composed of a second convex portion 42, a third convex portion 43, a fourth convex portion 44, and a fifth convex portion 45).

Each of the convex portions 41, 42, 43, 44, 45 of the convex portion group 40 is integrally formed with the bottom floor 31, and the bottom floor 31 can be carved out to give a desired shape or height dimension. I'm adjusting. Further, the convex portions 41, 42, 43, 44, 45 may not be integrally formed with the bottom laying 31, for example, each convex portion formed separately from the bottom laying 31 having a flat upper surface 31b. The convex portion group 40 can also be formed by pasting 41 to 45.

As shown in FIG. 6, these first to fifth convex portions 41, 42, 43, 44, 45 are arranged so as to wrap around the outer circumference of the hallux in a plan view. Each of these convex portions 41, 42, 43, 44, 45 has a unique function and effect depending on its position and shape.

As shown in FIGS. 3 and 4, the first convex portion 41 is located near the proximal phalanx 19a between the toes and the toes of the foot (between the fingers and near the base of the fingers). The shape of the first convex portion 41 has one side extending back and forth along the second toe, and is formed into a substantially triangular shape having an apex inside the one side. The dimensions of the first convex portion 41 are 5 mm to 30 mm in the lateral direction (inner and outer directions) of FIG. 4, 5 mm to 40 mm in the front-rear direction, and the T1 dimension in the height direction (thickness direction. FIG. 3B). ) Has a convex portion of 1 mm to 7 mm.

The second convex portion 42 has a base portion near the front side of the first convex portion 41 and extends in the toe direction. The dimensions of the second convex portion 42 are 2 mm to 10 mm in the lateral direction (inner and outer directions) of FIG. 4, 5 mm in the front-rear direction to the tip of the sole toe, and 1 mm to 7 mm in the height direction T1. ing.

The third convex portion 43 has a base near the inside of the first convex portion, and extends in the medial direction (direction of the hallux) so as to cross the proximal phalanx 19a of the hallux. The dimensions of the third convex portion 43 are 2 mm to 10 mm in the front-rear direction and 1 mm to 7 mm in the height direction T1 from 5 mm in the lateral direction (inner-outer direction) of FIG. 4 to the inner edge of the sole. There is.

The fourth convex portion 44 is formed in a substantially V-shape along the vicinity of the posterior margin of the ball of the hallux (near the proximal margin 18a of the head of the hallux of the hallux). The fourth convex portion 44 is arranged so that the heel side end has the maximum length and extends to the center of the medial cuneiform bone. Further, it is a convex portion of 1 mm to 10 mm in the height direction T1.

The fifth convex portion 45 is arranged from the vicinity of the posterior lateral edge of the ball of the hallux or from the vicinity of the medial side of the hallux bone along the curvature of the medial edge 31c of the sole. The dimensions of the fifth convex portion 45 are 2 mm to 15 mm in the lateral direction (inner and outer directions) of FIG. 4, from 15 mm in the front-rear direction to the tip of the sole toe at the maximum, and a convex portion of 1 mm to 7 mm in the height direction T1. It has become.

The first to fifth convex portions 41, 42, 43, 44, 45 have only one of these convex portions 41, 42, 43, 44, 45 according to the condition of the user's foot bone. It can be provided alone or in combination of two (or three, four, five).

By increasing the number of combinations, it is possible to increase the kicking force at a specific part near the hallux. That is, by changing the number of combinations and the combination pattern, it is possible to change the degree of kicking force at a specific part near the hallux or the degree of induction of COP near the hallux. It is possible to derive the optimum operation according to the above. Therefore, the first to fifth convex portions 41, 42, 43, 44, and 45 may be used alone or in combination.

These convex portion groups 40 are one form for moving the movement locus of the COP, and have been described in detail as an example, but the convex portion group 40 is not the only effective means. For example, the movement trajectory of the COP can be changed more appropriately by providing the convex portions separately along the outer edges of the forefoot portion A, the midfoot portion B, and the hindfoot portion C. As described above, which portion of the inner sole is provided with the convex portion is appropriately determined based on the state of the sole of the user's foot, the walking posture, the balance of the center of gravity of the body, and the like.

As described above, the combination of these convex portion groups 40, the detailed shape, or the shape of the convex portion provided in another portion such as the outer edge portion is manufactured by full custom (made-to-order) in consideration of user characteristics. At that time, each part of the foot of the user must be measured in detail, which has been conventionally performed face-to-face with a technician. The present invention has made it possible to manufacture a custom-made inner sole by the method described below in a non-face-to-face manner based on, for example, transmission / reception, response, and reception of data on the Internet.

To make it non-face-to-face, mainly the anatomical information of the foot and the motion information of the body are used. More specifically, it is information of (1) statistical model, (2) shape data based on ergonomics, (3) operation data as electronic data, and (4) interview data that can be answered on the Internet. By combining this information, it becomes possible to manufacture a custom-made inner sole of the same quality as that manufactured in a face-to-face manner in a non-face-to-face manner. The novel point to be noted in the present invention is not only the skeletal data of the foot itself (data in the state where the user is stationary), but also the motion data (state in which the user is moving) that can be exchanged as electronic data. The method is to determine the shape of the inner sole from the data).

(1) Statistical models are several types of foot lengths and sizes that are indispensable for creating inner soles that match the characteristics of individual feet, based on each foot size data measured from foot photographs. It is a model for calculation. The data that can be measured from the photograph is limited to the length between the anatomical landmarks of the foot (the part with a characteristic shape such as the protrusion of the bone), but it is difficult to measure the length to the part without the landmark. Is. On the other hand, by using a statistical model, it is possible to calculate the distance to a part without a landmark based on the data measured from the landmark. In addition, the value calculated by this statistical model can be mathematically derived to what extent the error occurs (error range), but this statistical model can be calculated within a practically small error range. Is mathematically clear.

(2) Ergonomic shape data refers to an average and neutral arch shape that can be used across races and genders. It has been found that the structure of the human foot, which consists of 28 bones on one foot, fits within a certain shape range regardless of gender or race. Based on this shape range, there is an average and neutral arch shape for functionally controlling the movement trajectory of the COP during operation. However, it is difficult to adapt to the characteristics of individual movements with this shape alone. It is an average shape to the last, and it can be said that the shape is premised on being deformed according to individual movements.

(3) Operation data as electronic data and (4) information acquired by the Internet are specifically the following electronic data, and (A) data acquired from directly above or from each direction of foot skeleton information. (Hereinafter, foot skeleton data), (B) comprehensive motion data, (C) interview data that can be answered on the Internet. (Hereinafter, interview data).

(A) The foot skeletal data is foot skeletal information acquired from directly above the foot or from each direction as needed, specifically, photographs, videos, and foot size information of the foot. Examples include data from sensors that can be acquired. Using these, the foot size is measured based on the anatomical landmarks of the foot (parts with characteristic shapes such as bone protrusions and joints).

Here, the foot size includes, in addition to the general foot length (length from the heel to the toe), the foot width and the distance to each toe.

The landmark sites are, specifically, the most protruding part inside the first metatarsophalangeal joint, the most protruding part outside the fifth metatarsophalangeal joint, the most protruding part of the heel bone, and the most protruding part of the toe. Examples include protruding parts and toe joints.

To measure this foot size, the foot size data based on the landmarks is used as an independent variable, and the original statistical model derived by multivariate analysis is used to calculate the foot size of the part without the landmarks. It can be said that this is a new point of the invention.
Multivariate analysis is a method of predicting some result from a plurality of independent variables in statistics, and one of them is multiple regression analysis. For a certain result (objective variable), out of multiple related factors (explanatory variables), which variable influences the result is quantified in the form of a function to express the relationship between the two, and based on that. It is a statistical method that can make predictions.

In the new method of calculating the foot size of the part without the landmark using statistics, the length of the most important and new part for fabrication is the length from the heel to the trailing edge of the ball of the toe. (Hereinafter, the trailing edge distance). The posterior margin of the ball, as the name implies, is the posterior (heel direction) end of the spherical first hallux joint. Even if the foot length (length from heel to toe) is the same, the trailing edge distance is not always the same. Therefore, in the conventional face-to-face method, it is very important to palpate the trailing edge of the ball of the toe, which differs between individuals, and to prepare the inner sole according to the site. In other words, the distinct difference between a custom-made inner sole and a factory-pre-made off-the-shelf inner sole for everyone, whether or not it fits the trailing edge of the ball, which varies from person to person. one of.

After calculating the trailing edge distance by the above method, the arch shape size based on ergonomics is determined. Once the trailing edge distance is determined, the shape of the human foot can adapt to an ergonomic arch shape across races. This ergonomic arch shape is an intermediate (neutral) and incomplete shape, and although it is not possible to properly guide different COP trajectories between individuals, it is a basic shape for guiding COP. Play a role.

By partially changing the shape in millimeters from this basic shape, the shape of the inner sole is changed to appropriately guide the locus of COP and body movement that differ among individuals. By changing the shape with more than 1000 types of patterns, it is possible to manufacture a custom-made inner sole by changing the shape to the shape pattern that best suits the movement of the individual. The data required for this shape are the operation data and the interview data of (B), (b-1) to (b-5) and (C) described below.

(B) Comprehensive motion data is motion data obtained comprehensively as electronic data of activities of daily living and playing sports. The term "comprehensive" as used herein refers to continuous data in which a plurality of operations are mixed, and refers to operation data as electronic data that does not limit a specific operation to be performed. For example, continuous motion data such as getting up from a chair, starting to walk, turning and reaching the target place as in daily life, and throwing, running, turning and stopping as in sports. It is a continuous operation. It is preferable that these comprehensive movements record continuous movements for about 1 minute, and it is preferable that various movement elements are included as described above. Further, it is even better that the data is acquired from two directions at the same time. A method of taking a picture from a camera fixed with a tripod or the like is preferable, but the measuring terminal may be moved so as to follow the subject as necessary. In order to improve the accuracy of the data, it is preferable to acquire the data in a state closer to the target person.

Further, (B) when it is difficult to acquire comprehensive operation data, five kinds of modified operation data as electronic data may be used as a modified method. The five modified motion data are (b-1) one-leg standing balance motion data (hereinafter, one-leg balance data), (b-2) in-situ stepping motion data (hereinafter, stepping data), and (b-). 3) Walking motion data (hereinafter, walking data), (b-4) Motion data (hereinafter, side step data), (b-4), which continuously and quickly performs a repetitive side jump or a similar turning motion in the left-right direction. 5) There are five types of motion data peculiar to sports (for example, golf swing motion in the case of golf, swing motion and pitching motion in the bad in the case of baseball (hereinafter, peculiar motion data), etc. The operation data is used by any one or a combination of two or more.

The above-mentioned electronic data is all data that can be transmitted and received via an Internet line, and includes, for example, moving image data, still image data, sensor data, audio data, text data, CSV data, XML data, and the like.

Further, the sensor data is data measured by various sensors for detecting movements provided in smartphones, tablet terminals and the like. For example, there is acceleration data acquired by an accelerometer. By repeating the differential processing on the obtained data, it is possible to acquire the data related to the velocity and the position, so that the operation can be expressed by the data. In addition, there is real space data represented by recent sensing technology. This is sensor data known as AR (Augmented Reality) technology, which irradiates the surrounding real environment with laser light and measures scattered and reflected light to measure the surrounding situation including human movement. Is to recognize. As described above, it has become possible in recent years to convert human movements into data using various sensors.

(B-1) One-leg balance data, which is one of the variants of (B), is an evaluation method that embodies the state of whole-body balance in all movements, so it is a modification of comprehensive motion data. Can be. Motion data is based on the evaluation of the whole body, and in some cases, the partial movement (balance) is evaluated. Basically, data is acquired from the front, but if necessary, it is performed from each direction. Hold one leg standing for a few seconds and switch left and right. Further, an applied operation may be added as needed. Focus on the difference in how to balance both feet and one foot standing on the whole body.

(B-2) The stepping data, which is one of the modified methods of (B), is an evaluation method that embodies the balance of standing on one foot and the state of walking, and can be a modified method of comprehensive motion data. The height, speed, and number of times the legs are raised are changed as necessary, and the evaluation is performed by paying attention to the movement of each part of the body when performing these.

(B-3) Walking data, which is one of the variants of (B), is one of the most frequently performed movements in daily life, and the collapse of walking causes general troubles and deterioration of performance in sports. It can be a variant of comprehensive behavioral data because it is so common. Obtain data on the walking distance from the front and back, and if necessary, from the side. Conditions such as walking speed are changed as needed. It is preferable to perform several trials of walking to grasp the tendency of movement.

(B-4) Side step data, which is one of the variants of (B), can be switched between left and right in various ways in sports, and the ability to turn left and right directly affects the performance of sports. It can be a variant of the data. Acquire data from the front of the side step operation and from each direction as needed. Evaluate how the legs and body parts are used to perform the turning motion in the left-right direction.

(B-5) The peculiar movement data, which is one of the variants of (B), has different peculiar movements for each sport. In the case of sports, it goes without saying that it is important to evaluate the sports movements required to change the shape according to the performance to be achieved. For example, in the case of golf, motion data for each sport, such as a swing motion of golf and a batting motion in baseball, is acquired from a necessary direction.

For the above-mentioned comprehensive operation data and the above-mentioned five modified operation data used as necessary, the user or an assistant acquires the operation data as electronic data, and exchanges the Internet and other electronic data. Get through. The COP locus is estimated from these motion data, and the shape is changed by several millimeters in a pattern to optimize it. In addition, the method of changing the shape is determined from the motion data by an original algorithmized method. For example, the human and the computer make a judgment on the shape change by using the relationship between the degree of shoulder shaking during movement and the position of the pelvis, the direction in which the foot is kicked, and the like as evaluation points.

(C) The interview data mainly acquires information on (I) the position of the octopus on the foot, (II) the type of trouble, and (III) the pain in the body. By these (I) to (III), the accuracy of the shape change determined from (B), (b-1) to (b-5) and (C) is improved, and whether the shape change does not burden the body. to decide. That is, the final confirmation of the shape change determined from the operation data can be performed with these data. In addition, if necessary, before the shape change based on the motion data, the interview data may be prioritized for evaluation and the motion data may be referred to based on the evaluation.

(I) The position of the octopus on the foot means that the octopus on the sole of the foot has thickened skin, so that the site is repeatedly loaded. That is, the COP often has a trajectory that passes through the octopus portion during operation, and the validity of the judgment evaluated from the operation can be confirmed by the position of the octopus on the sole of the foot. Further, by first evaluating the position of the octopus on the sole of the foot and then evaluating the movement based on the information, more accurate movement analysis becomes possible.

(II) As for the type of trouble, the locus of COP becomes characteristic depending on the type of trouble. In the case of knee pain or hip pain, there is a strong tendency to swing the shoulder from side to side and walk, and the movement of COP that accompanies it is characteristically shown. Similar to (I) the position of the octopus on the foot, these also contribute to confirmation of the validity of the judgment evaluated from the movement and more accurate movement analysis.

(III) With regard to body pain, the body skillfully uses escape movements and compensatory movements to avoid the burden as much as possible, and tries to reduce the pain. However, these unusual behaviors can cause the following problems: By investigating what kind of pain and what kind of pain is in which part in this way, it is possible to confirm the validity of the shape change judgment obtained from the evaluation of the movement and to make the movement more accurate. Enables analysis.

By acquiring electronic data using the Internet with the above scheme, it is possible to manufacture a custom-made inner sole of the same quality as the face-to-face type in a non-face-to-face manner.

According to the method for manufacturing an inner sole according to the embodiment of the present invention, the shape of the convex portion provided on the inner sole is determined based on the operation data as electronic data in the user, so that communication such as the Internet is performed. Based on various data transmitted through the line, it is possible to manufacture a custom-made inner sole that matches the dynamic foot and physical condition without the need for face-to-face contact with a technician.

In addition, based on the foot skeletal data obtained from the user's foot skeletal information, the foot size is measured from the shape of the protruding portion of the foot bone, and the foot size data is used as an independent variable. Since the foot size of the part of the foot where the bone does not protrude is calculated using the original statistical model derived by variable analysis, the foot size that had to be measured face-to-face in the past was calculated. The foot size of the part without the protrusion of the bone (the part without the landmark) can be calculated without performing face-to-face measurement. Therefore, it is possible to manufacture a custom-made inner sole suitable for the user only by obtaining the foot skeleton data, which is the skeleton information of the foot.

In particular, by calculating the length from the heel of the foot, which has the largest individual difference, to the trailing edge of the ball of the toe, this dimension, which until now could only be measured face-to-face, can be measured without face-to-face measurement. It can be calculated. Therefore, it is possible to manufacture a custom-made inner sole suitable for the user simply by transmitting and receiving foot skeleton data via an internet line or the like.

In recent years, there has been a method for manufacturing an inner sole mainly using foot shape data using a sensing technique such as a 3D scanner. However, the last data acquired by a 3D scanner or the like is the user's static last (last standing, lying down, and sitting), which is completely different from the moving last. The shape is kinematically and anatomically clear. Rather, the foot is constantly deformed during movement according to the position where the load is applied, the shape of the floor surface, etc., and this deforming foot function is the basis of such excellent human walking ability. It is made up. Therefore, it is difficult to manufacture an optimum inner sole that matches the dynamic foot and physical conditions such as walking and sports with the inner sole mainly produced by this static foot shape data. The present invention is a more logically valid, rational and novel method that makes it possible to determine the shape of the convex portion provided on the custom-made inner sole based on the dynamic motion data. It is superior to the conventional manufacturing method mainly based on static foot shape data obtained from a 3D scanner or the like.

Further, since it has a process of partially changing the shape of the inner sole based on the comprehensive motion data obtained as comprehensive electronic data of activities of daily living and playing sports, the inner sole has a process. The shape of the provided convex portion can be partially changed or finely adjusted in millimeters based on these data. This makes it possible to manufacture a custom-made inner sole that can correct the movement trajectory of COP that differs between individuals to the optimum position.

Furthermore, as a variation of the comprehensive motion data, any one or two or more of the five modified motion data as electronic data, one-leg balance data, stepping data, walking data, side step data, and peculiar motion data. It is also possible to fine-tune the shape of the convex portion based on the combination of.

In addition, the shape of the inner sole is partially changed based on the interview data, which is information about the position of the octopus on the foot, the type of trouble that the body has, and the part of the body that is in pain. ), (B-1) to (b-5) and (C), it is possible to determine whether the shape change is a burden on the body and the accuracy is improved by the shape change. Therefore, it is possible to manufacture a custom-made inner sole that is more suitable for the user.

Furthermore, by acquiring the foot skeleton data, motion data, or interview data as electronic data obtained from the user's foot skeleton information via the Internet line, it is not necessary to meet with a technician, and it is made to order. Various data necessary for manufacturing the inner sole can be easily transmitted and received via the Internet or the like. Therefore, it is possible to solve the problem of service disparity between regions and the problem of soaring selling prices, which have been problems of custom-made production. In addition, by making a bespoke inner sole that matches the dynamic foot and physical condition, we will make a better bespoke inner sole that has higher quality and medical logical validity than the conventional one. It becomes possible.
