Description

Pillow fit method by body type and its system {METHOD FOR SELECTING PILLOW BY BODY TYPE AND SYSTEM THEREFOR}

The present invention relates to a pillow automatic fitting system, and in particular, after measuring and analyzing the body size, neck shape and body pressure distribution of each individual according to the pillow selection program constructed in consideration of various measurement data and various variables, refer to individual preferences The present invention relates to a pillow fit method and system for each type of body that automatically selects an optimal pillow.

Human life is a one-day complete, 24 hour cycle, and the biorhythm of rest and activity is repeated to lead a healthy life. However, in today's complex social life, there is an increasing number of factors that confuse these rhythms.

Sleep, which plays a major role in rest, aims to sustain physiological rhythms, to restore the body's fatigue, to rejuvenate the mind and body, and to regenerate new energies, which is not only quantitative but also qualitative. In terms of face, sufficient and efficient facial is required.

Therefore, it is important to study the sleeping environment for getting a good night's sleep, especially the bedding that is one-third of daily life as a sleeping tool. If bedding is uncomfortable, sleep can't be slept, so the condition of bedding obtained by studying the human body's sleeping posture and body movement during sleep from ergonomics can be said to be the cornerstone for creating a better sleeping environment.

Among these important bedding, especially pillows have a great effect on the face by playing a role of supporting the body in a natural state in a lying position.

Improper use of pillows can cause fatigue, prolonged use of the cervical spine and cervical muscle pain, which can affect skeletal development in children with growth. There is a risk of cerebral hemorrhage or stroke as the body ages by obstructing blood circulation by bending the vein, and various studies have reported that the neck and neck muscles are tense.

Too much elastic pillow gives strong irritation to the tritubules in the ear, which sometimes causes dizziness, and there are a lot of depressions to accumulate heat and prevent heat from sleeping. It is difficult to maintain the posture because it is not firmly supported, and many areas are sunk into the bedding, which prevents sweat from evaporating and makes you feel uncomfortable.

In addition, there are various factors that affect the comfortable sleep, such as size, touch, absorbency, elasticity of inner material, thermal conductivity, and shape safety. It is strong and has large individual differences.

Despite the importance of such pillows, studies on comfortable pillows that fit the body of Koreans are currently insignificant.

Therefore, there is an urgent need for scientific research for selecting a standard for a pillow suitable for each individual body shape.

Therefore, the present invention has been devised in the above-described purpose, by standardizing a variety of pillows suitable for the individual body type, by measuring and analyzing the individual body shape in an objective and quantitative manner to select a suitable pillow for each individual The purpose is to provide a pillow fit method and system.

In addition, another object of the present invention, after measuring the individual dimensions and neck shape and body pressure distribution according to the pillow selection program constructed in consideration of the various measurement data and various variables, the optimum height with reference to the individual preferences The present invention provides a method of fitting a pillow according to a body type and a system for automatically selecting a pillow having a hardness and hardness.

It consists of 58.

On the other hand, the present invention measured the body of the customer divided the pillow 10 into five levels of height and five levels of hardness, that is, a total of 25 kinds of polyurethane pillows were produced, KS A 7003 and Based on KS A 7004 (Korea Industrial Standards Association, 1989), it is based on the height, weight, weight, length of hair, head thickness, head width, head circumference, neck circumference, neck length, head to back head length , Head ridge-cervical point length was measured, respectively, as a reference for the manufacture of the pillow was produced a cervical support pillow.

In addition, the present invention is to measure the human body using a separate measuring device before selecting a suitable pillow for the customer, which is C7 (Cervical 7) at the bottom of the flat plate when the customer lying down flat posture Cervical spine height up to the cervical spine and neck depth, the deepest part of the neck at the bottom.

In the human body, the neck is an important part of the passage between the head and the body. There is a small hole around the neck, and intervertebral nerves (를 神經) pass between them, if the bending of the neck bone is out of the normal, these holes narrow and press the nerves to feel pain, the airway narrows, breathing Difficulty and severe snoring.

Neck and head pillows play a very important role in maintaining the health of the cervical spine, the beginning of the spine, but the height of the pillow should be different because each person's appearance is different. When the pillow is laid down, it is necessary to maintain proper curvature (S-curve) of the cervical spine when the pillow is lying down. Head injury, neck, shoulder, and back pain may be caused by damage to the cervical spine. Therefore, in order to select and evaluate an appropriate pillow, the shape of the neck area should be measured.

3 to 6 show a screen display program showing an operation process of the present invention, which will be described with reference to FIGS. 1 to 2.

3 is an initial screen of the pillow selection program displayed on the monitor according to the program recorded in the personal computer 70 when the automatic pillow selection program is executed. At the bottom of the screen, there is an area for inputting the body shape information of the customer.

In this area, enter the customer's name, gender, age, height, weight, cervical spine, neck height, etc.Special features such as cervical spine height and neck height should be measured through a separate device and then the measured values Done.

And, if you select the submenu 'New file' from the 'File' menu, all input contents are cleared and the initial screen is changed.

After entering all the above items, click the 'Survey' menu at the top to display the questionnaire screen as shown in FIGS. 4A and 4B, and the preferred hardness of the pillow, the preferred height of the pillow, various sleeping environment (bed or ondol), use pillow Fill out or select the answers to the questionnaire about the ingredients, the shape of the pillow you use, and what you consider most when you buy the pillow.

When everything has been entered and selected, click the 'OK' button at the bottom. At this time, if the input is missing or wrong, a push-pull confirmation screen is displayed and data can be entered or corrected according to the displayed screen.

After selecting the 'OK' button and clicking the 'Pillow selection' item, which is a submenu of the 'View' menu, the personal computer 70 receives the input data of the customer based on a program set in the personal computer 70 in advance. After analyzing the data, the optimal pillow of the customer is selected and displayed in the first to third ranks by the push-pull method as shown in FIGS. 5A and 5B. When the customer checks the optimal pillow and clicks the 'OK' button at the bottom, the selected pillow ranking screen disappears.

Here, the pillow has been set in advance on the personal computer 70 for the pillow having a total of 25 different hardness and height due to the five stages of hardness and five stages of height classification, double input and selected survey data Based on this, the most suitable pillow for the customer is selected and displayed on the screen.

Then, the push-pull pillow ranking screen disappears, and the screen shows a 3D graphic of the body pressure when a customer uses an appropriate pillow or an inappropriate pillow, and shows a high rigid pillow, a low rigid pillow, and a high The body pressure state of the soft pillow and the low and soft pillow is shown graphically, and after confirming, clicking the 'OK' button at the bottom disappears and the initial screen as shown in FIG. 3 is displayed.

Click the 'Communication' menu on the initial screen to connect the communication between the body pressure meter and the computer.

Subsequently, the body pressure measurement plate 30 of the measurement system as shown in FIG. 1 is placed on the upper side of the general pillow, and the body pressure distribution appears by laying the head on the body pressure measurement plate 30 to measure the 'scan' on the initial screen. After clicking the menu and clicking the submenu 'General pillow body pressure measurement', the personal computer 70 reads and analyzes measurement data from a plurality of pressure sensors of the body pressure measuring plate 30, and then displays the upper left screen of FIG. 6A. The body pressure is expressed as a graph distribution diagram as follows. Then, in the most comfortable state, the client selects the 'Stop' item of the 'Scan' menu to confirm the body pressure distribution.

Then, the body pressure measuring plate 30 is placed on the optimum pillow selected above, and the client presses his head on the body pressure measuring plate 30 and then presses the 'pillow body pressure measurement' which is a sub-menu of the 'scan' menu on the initial screen. When the item is clicked, the personal computer 70 reads and analyzes the measurement data from the pressure sensors of the body pressure measuring plate 30 and displays the body pressure as a graph distribution diagram as shown in the upper right screen of FIG. 6B. As shown in FIG. 6B, the pressure is evenly distributed throughout the pillow in the case of the appropriate pillow, while the pressure value is distributed more than 200 in a specific area in the case of the improper pillow (the color may be unclear on the print). ). Then, in the most comfortable state, the client selects the 'Stop' item of the 'Scan' menu to confirm the body pressure distribution.

Subsequently, when the user clicks the 'save' item, which is a submenu of the 'File' menu, the personal computer 70 stores the questionnaire data and the body pressure distribution of the customer measured as described above in the personal computer 70, and if necessary, The computer 70 can be searched and reconfirmed.

On the other hand, in order to quantify the body pressure measurement, the normal distribution, which is the optimal pressure distribution, is analyzed and set, and the degree of distribution (biased) of the body pressure distribution to the neck and shoulders is biased to the left / right side compared to the normal distribution based on the back passage point The skewness, and kurtosis, which represents the density of the distribution centered on the mean of the normal distribution, are required.

The body pressure measuring system measures the body pressure of the head and neck of the client applied to the pillow by using the body pressure measuring plate 30 equipped with a pressure sensor of 8 * 16 bytes as shown in FIG. 1, in the case of a high and hard pillow There is a lot of pressure on a certain part of the head and there is a lot of pressure on the shoulder, so there is a lot of pressure.In the case of a low, hard pillow, only a certain part of the head is under great pressure. In case of high and soft pillows, the pressure distribution is relatively lower than in the case of high and soft pillows, but there is a lot of recessed area, which causes a lot of discomfort. In addition to receiving a relatively high pressure on the side only a lot of depressions due to the heat release is a lot of discomfort.

In addition, the method of analyzing the measured body pressure distribution in the personal computer 70 may grasp the characteristics of the data from the tap water distribution table, but the measurement values use a lot of measurement measures that can be objectively represented.

A measure of location, usually referred to as the representative value, which indicates which values the given data X1, X2, ..., Xn are distributed around, and the degree to which the data are scattered around each representative value. Note that dispersion measures are widely used.

Commonly used positional measures include mean, median, mode, geometric mean, harmonic mean, and the like.

These are collectively referred to as representative values, the most common of which are defined as the mean and median of the data.

Consider the distribution as an important measure of the shape of the distribution, along with the representative values, because the two sets of data may have very different distributions, even if they have the same representative value.

Therefore, it is necessary to find out how far the individual data are from the center position.

However, since the sum of the deviations is 0 as in Equation 1, if the (n-1) deviations are known among the n deviations, the remaining one deviation is determined by itself.

This shows that only n-1 of the n values are irrelevant.

Therefore, the sum of their squares divided by n-1 is defined as the variance of the data. On the other hand, since the variance is not the same units of data, the square root of the amount of variance of the data is a standard deviation as a measure of dispersion having the same units as the data. This is shown in Equations 2 and 3, respectively.

Kurtosis represents the density of the distribution centered on the mean value, and the closer the absolute value of kurtosis is to the normal distribution, the more kurtosis spreads than the normal distribution. When it is narrower than the normal distribution, it shows a sharp distribution.

Skewness represents the skewness of the distribution. The closer the absolute value of the skewness is to 0, the more similar the normal distribution is, and + skewness shows the right tail distribution biased to the left. It shows a biased left tail distribution.

Experimental Example

Based on such measurement factors and body pressure analysis factors, the average of a large number of customers measured when cutting various pillows (12 experiments with 12 types of pillows) classified as shown in Table 1 by the system shown in FIG. The body pressure is explained as follows.

Hardness Soft Height High ↕ Low 1-1 1-2 1-3 1-4 2-1 2-2 2-3 2-4 3-1 3-2 3-3 3-4

The external specifications and characteristics of the 12 types of pillows in Table 1 are shown in Table 2 below.

Characteristics of each pillow weight Neck Depression Head width Length Pillow type 1-1 1.6 kg 14 cm 10.1 cm 11.1 cm 30.92 cm 49.22 cm 1-2 1.65 kg 1-3 1.7 kg 1-4 1.85 kg 2-1 1.4 kg 11.8 cm 7.81 cm 8.96 cm 2-2 1.4 kg 2-3 1.45 kg 2-4 1.55 kg 3-1 1.1 kg 9.83 cm 6.24 cm 7.36 cm 3-2 1.15 kg 3-3 1.2 kg 3-4 1.25 kg

In conclusion, when the median, standard deviation, skewness and kurtosis values are measured for a large number of clients with the pillow shown in Table 2, the average values are shown in Table 3. .

Measuring element median Standard Deviation Dwarf Kurtosis Pillow type 0-0 338.5 240.98 0.19 -2.17 2-1 132.5 93.34 1.77 2.38 3-1 128 77.02 1.31 0.76 3-2 163 72.78 1.13 1.07 1-2 123 64.59 0.93 -0.63 2-2 131 63.37 1.12 0.15 1-3 119 54.40 1.04 1.99 1-4 123 54.37 0.54 1.61 2-3 136.5 54.33 -0.17 -0.21 3-4 139 53.38 1.32 1.54 1-1 151 53.18 1.01 0.07 2-4 149 53.01 -0.71 0.95 3-3 133 48.26 0.47 -0.65

If you lie on the floor without using a pillow (in case of 0--0), the standard deviation and median value are the highest, which results from the distribution of the body pressure in a small area.

In the case of 1-1 pillows, the pressure distribution is generally dispersed and the standard deviation value is small because there are many areas in contact with the pillow, and the pressure value is almost the same as other pillows, and the kurtosis value is 0.07, which is close to the normal distribution.

In the case of 2-1 pillows, the skewness value is the largest and tends to be biased to one side from the mean of the normal distribution, while the 3-1 pillows are also low, rigid pillows with a large median and standard deviation value. + Skewed to one side with distortion. This is the same as the previous explanation that the body pressure value is high and is not evenly distributed, but it is biased toward the head protrusion because it is low and hard.

Therefore, the harder the pillow, the greater the median and standard deviation.

Soft pillows such as 2-3, 2-4, and 3-3 also have a large median but a small standard deviation because the low pressure values are evenly distributed. In the case of the soft pillow, kurtosis is -0.21, 0.95, and -0.65, respectively, and the body pressure is evenly distributed close to the average value, but in the case of 3-4, the kurtosis value and the skewness value are 1.54 and 1.32, respectively. This is concentrated in one place.

That is, as shown in Table 3, the high and hard pillow has a large median value, a standard deviation value, and a large skewness value. This is because the pressure value is high overall and the difference between the high and low pressure values is large, so that the pressure value is not evenly distributed and the body pressure distribution is biased to one side. Especially in the low hard pillow, the body pressure tends to be concentrated on the protrusion of the head. It can be seen that.

However, as in the case of the 1-1 pillow, the high and hard pillows have a kurtosis value in which the body pressure distribution is distributed at almost the same pressure because the head and shoulders touch the pillow.

In the case of soft pillows, the median is large, but the standard deviation is small. The kurtosis value is close to 0, indicating that the body pressure is evenly distributed near the mean value.

However, in case of 3-4 pillows, the lower and harder pillows among 12 pillows, the skewness and kurtosis value are large, which is soft and low, and thus the pressure is more distributed than other pillows.

Therefore, in selecting the optimal pillow, the median, standard deviation, skewness, and kurtosis values, which are important factors, are different for each type of pillow, as shown in Table 3, so that the optimal fit for each individual is referred to by referring to the client's body characteristics and preferences. It is important to select the pillow of the present invention, the present invention is a program that selects the optimal pillow to the customer based on such data.

While specific embodiments of the present invention have been described and illustrated above, it will be apparent that the present invention may be embodied in various modifications by those skilled in the art. Such modified embodiments should not be individually understood from the technical spirit or the prospect of the present invention, and such modified embodiments should fall within the appended claims of the present invention.

Therefore, in the present invention, by standardizing a variety of pillows suitable for the individual body shape, by measuring and analyzing the individual body shape and taste in an objective and quantitative manner automatically selects the most suitable pillow, due to the use of inappropriate pillows By removing all kinds of phenomena such as sleep disorders and muscle pain and skeletal abnormalities of the neck, it provides a more comfortable and comfortable sleep, which can greatly contribute to national health.
