Description

Technical Field

[0001] The present invention relates to the technical field of mattress manufacturing, in particular to a method for manufacturing a personalized side-sleeping mattress. Background Art

[0002] Sleep quality is crucial for modern people, impacting both their health and the next day's performance. Mattresses are a crucial factor influencing sleep quality. Every consumer has their own mattress firmness preferences, and the same person requires different support for different body parts in different sleeping positions. Furthermore, due to differences in body shape, different people require varying support for the same sleeping position. Choosing a personalized mattress that suits your body type and sleeping preferences, providing precise support for different body parts during sleep, is crucial for improving sleep quality and maintaining good health. A mattress's structure generally consists of a support layer, a cushioning layer, and a fabric composite layer. These layers form a cohesive whole and collectively determine the mattress's mechanical properties and support characteristics. The support layer is a crucial factor in determining the mattress's overall support performance. Among the materials used for the mattress's support layer, spring nets are one of the most technologically mature and reliable options. By optimizing the layout of the spring nets, the mattress's overall mechanical properties can be improved, allowing it to better accommodate consumers' body types and firmness preferences.

[0003] Although the single-size zoned mattresses currently on the market claim to have different zoned designs, they are actually still based on a "one-size-fits-all" manufacturing concept, attempting to adapt a fixed design to everyone's physical characteristics. This approach ignores ergonomic principles and fails to consider individual differences in height, weight, body shape, and firmness preferences. Therefore, although this type of mattress is nominally "zoned," it cannot actually provide optimal personalized body support for each person and is, to a certain extent, a "pseudo-zoned" mattress. In addition, current mattress designs are generally based on the supine sleeping position, but side sleepers also account for a large proportion of users. Designing based solely on the supine sleeping position cannot provide precise body support for those who prefer side sleepers.

[0004] Therefore, there is an urgent need for a personalized mattress manufacturing method for side sleeping posture. Summary of the Invention

[0005] In view of the above analysis, an embodiment of the present invention aims to provide a method for manufacturing a personalized side-sleeping mattress to solve the problem that existing mattresses cannot meet customers' personalized needs for side-sleeping postures.

[0006] An embodiment of the present invention provides a method for manufacturing a personalized side-sleeping mattress, which is characterized by comprising the following steps:

[0007] Obtaining customers' body data;

[0008] Based on the acquired customer's body data, the number of spring rows in each longitudinal area of the side-sleeping mattress is obtained;

[0009] Based on the acquired customer's body data and the set spring hardness level, a baseline hardness level of the side-sleeping mattress spring is obtained;

[0010] Based on the customer's anatomy data and the pre-set spring hardness gradient patterns and pattern discrimination model, a discriminant function value for each spring hardness gradient pattern is obtained; wherein the spring hardness gradient pattern represents the spring hardness relationship between different areas of the side-sleeping mattress;

[0011] Determining the optimal spring hardness gradient pattern based on the discriminant function value of each spring hardness gradient pattern;

[0012] Based on the number of spring rows in each area of the side sleeper mattress, the baseline hardness level of the side sleeper mattress springs and the optimal spring hardness gradient pattern, the customer's personalized side sleeper mattress is obtained.

[0013] Furthermore, the spring hardness gradient pattern corresponding to the maximum value among the spring hardness gradient pattern discriminant function values is taken as the optimal spring hardness gradient pattern.

[0014] Furthermore, the pattern discrimination model is expressed as:

[0015]

[0016] Where p i represents the discriminant function value of the i-th spring hardness gradient mode, g i 、g i′ They represent the reference values of the i-th and i′-th spring hardness gradient modes respectively, and I represents the total number of spring hardness gradient modes.

[0017] Furthermore, the spring hardness gears include soft gear, medium gear, hard gear and extra hard gear from soft to hard; the spring hardness gradient modes include CA mode, CB mode and CC mode;

[0018] The CA mode is that the spring hardness level of the shoulder area is two levels softer than that of the head and neck area; the spring hardness level of the back area is one level harder than that of the shoulder area; the spring hardness level of the waist area is the same as that of the back area; the spring hardness level of the buttocks and thigh root area is one level softer than that of the waist area; the spring hardness level of the leg and foot area is one level harder than that of the buttocks and thigh root area; wherein the spring hardness level of the shoulder area is the baseline hardness level;

[0019] The CB mode is as follows: the spring hardness level of the shoulder area is one level softer than that of the head and neck area; the spring hardness level of the back area is the same as that of the shoulder area; the spring hardness level of the waist area is one level harder than that of the back area; the spring hardness level of the buttocks and thigh root area is one level softer than that of the waist area; the spring hardness level of the leg and foot area is one level harder than that of the buttocks and thigh root area; wherein the spring hardness level of the shoulder area is the baseline hardness level;

[0020] The CC mode is that the spring hardness level in the shoulder area is one level softer than that in the head and neck area; the spring hardness level in the back area is the same as that in the shoulder area; the spring hardness level in the waist area is the same as that in the back area; the spring hardness level in the buttocks and thigh root area is one level softer than that in the waist area; the spring hardness level in the leg and foot area is one level harder than that in the buttocks and thigh root area; among which, the spring hardness level in the buttocks and thigh root area is the baseline hardness level.

[0021] Furthermore, the reference values g1, g2, and g3 of the CA mode, CB mode, and CC mode are respectively expressed as:

[0022] g1=0

[0023] g2=12.219-5.019×s+0.547×a BMI +0.703×q1-17.921×q2

[0024] g3=17.036-5.426×s+0.231×a BMI +0.155×q1-14.769×q2

[0025] In the formula, s represents the gender of the customer, which takes the value of 0 or 1, where 0 represents female and 1 represents male; a BMI Indicates the customer's BMI value; q1 indicates the linear shoulder width to waist width ratio, and q2 indicates the linear hip width to waist width ratio.

[0026] Furthermore, the spring hardness level of level 1 is regarded as the extra hard level, the spring hardness levels of levels 2 to 3 are regarded as the hard level, the spring hardness levels of levels 4 to 6 are regarded as the moderate level, and the spring hardness levels of levels 7 to 9 are regarded as the soft level.

[0027] Furthermore, the number of spring rows in each longitudinal area of the side-sleeping mattress is obtained by the following method:

[0028] Divide the human body into parts, and obtain the customer's body data based on the divided parts of the human body, and then obtain the longitudinal dimensions of each part of the human body;

[0029] Based on the longitudinal dimensions of each part of the human body, the number of spring rows in each longitudinal area of the side-sleeping mattress is obtained; wherein each part of the human body corresponds to each longitudinal area of the side-sleeping mattress one by one.

[0030] Furthermore, the divided parts of the human body are the head and neck, shoulders, back, waist, buttocks and thigh roots, legs and feet;

[0031] The human body data includes basic human body data and detailed human body data;

[0032] The basic human data includes gender, weight, and mattress firmness preference;

[0033] The detailed human body data includes height, height of the back cervical vertebrae point, height of the shoulder blade protrusion point, height of the nipple point, height of the horizontal waistline, height of the front abdominal protrusion point, height of the horizontal line of the lower end of the gluteal groove, height of the midpoint of the knee, straight-line shoulder width, straight-line hip width, and straight-line waist width.

[0034] Furthermore, the longitudinal dimensions of each part of the human body are obtained by:

[0035] The longitudinal dimension of the head and neck = height - height of the posterior cervical vertebrae;

[0036] The longitudinal dimension of the shoulder = the height of the posterior cervical vertebra - the height of the scapula protrusion + 0.5 × (the height of the scapula protrusion - the height of the nipple point);

[0037] The longitudinal dimension of the back = 0.5 × (shoulder blade height - nipple height) + 0.5 × (nipple height - horizontal waistline height);

[0038] The longitudinal dimension of the waist = 0.5 × (nipple point height - horizontal waistline height) + (horizontal waistline height - abdominal convex point height);

[0039] The longitudinal dimension of the buttocks and thigh root = (height of the anterior abdominal convex point - height of the horizontal line of the lower end of the gluteal groove) + 0.382 × (height of the horizontal line of the lower end of the gluteal groove - height of the midpoint of the knee);

[0040] The longitudinal dimension of the leg and foot = 0.618 × (height of the horizontal line at the lower end of the gluteal groove - height of the mid-point of the knee) + height of the mid-point of the knee.

[0041] Furthermore, the longitudinal dimensions of each longitudinal region of the mattress are obtained by:

[0042] The longitudinal dimension of the head and neck area in the mattress = max{longitudinal dimension of the human head and neck, set pillow width};

[0043] The longitudinal dimension of the shoulder area of the mattress = the longitudinal dimension of the human shoulder;

[0044] The longitudinal dimension of the back area of the mattress = the longitudinal dimension of the human back;

[0045] The longitudinal dimension of the lumbar region of the mattress = the longitudinal dimension of the human waist;

[0046] The longitudinal dimensions of the mattress's buttocks and thigh root areas = the longitudinal dimensions of a person's buttocks and thigh root areas;

[0047] The longitudinal dimensions of the longitudinal area of the legs and feet in the mattress = max{longitudinal dimensions of the human legs and feet, set standard longitudinal dimensions of the mattress - longitudinal dimensions of all other longitudinal areas in the mattress}.

[0048] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:

[0049] The present invention provides a method for producing a personalized side-sleeping mattress, which fully considers the customer's body shape characteristics and mattress softness and hardness preferences when sleeping on the side, determines the number of springs arranged in each partition of the side-sleeping mattress according to the longitudinal dimensions of each divided part of the customer's body; determines the minimum baseline hardness level spring required for the side-sleeping mattress according to the BMI value and the mattress hardness preference; and determines the spring hardness gradient of each partition of the side-sleeping mattress according to the body shape characteristics, thereby obtaining a personalized side-sleeping mattress that accurately adapts to the user's body shape characteristics and hardness preferences, achieves more scientific sleep support, improves sleep quality, and provides mattress companies with forward-looking production planning.

[0057] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, and are not used to limit the scope of the present invention.

[0058] Example 1

[0059] A specific embodiment of the present invention discloses a method for making a personalized side-sleeping mattress, such as Figure 1 As shown, the following steps are included:

[0060] S1. Obtain the customer's body data;

[0061] S2. Based on the acquired customer's body data, the number of spring rows in each longitudinal area of the side-sleeping mattress is obtained;

[0062] S3. Based on the acquired customer's body data and the set spring hardness level, a baseline hardness level of the side-sleeping mattress spring is obtained;

[0063] S4. Based on the client's anatomy data and the predefined spring hardness gradient patterns and pattern discrimination model, obtain a discriminant function value for each spring hardness gradient pattern; and determine an optimal spring hardness gradient pattern based on the discriminant function value for each spring hardness gradient pattern; wherein the spring hardness gradient pattern represents the spring hardness relationship between different regions of the side-sleeping mattress;

[0064] S5. Based on the number of spring rows in each area of the mattress, the baseline hardness level of the mattress springs, and the optimal spring hardness gradient pattern, a personalized mattress is obtained for the customer.

[0065] It is understandable that the personalized mattress manufacturing method in this embodiment is applicable to the production of both single and double mattresses. For a double mattress, corresponding mattress units can be manufactured according to the respective characteristics of the two customers, and they can be spliced and combined to achieve personalized customization. In addition, this embodiment is designed and optimized for the side sleeping position, and can provide a better and more comfortable sleeping experience in the side sleeping position. It should be noted that the requirements for the mattress springs to fit the human body curve in the side sleeping position are higher than those in the supine sleeping position. Therefore, it is also very comfortable to use a side sleeping mattress in the supine sleeping position. Therefore, the side sleeping position is also suitable for the mixed supine and side sleeping position.

[0066] It will be understood by those skilled in the art that, after obtaining the customer's anatomy data, the number of spring rows in each area of the mattress, the baseline hardness level of the mattress springs, and the optimal spring hardness gradient pattern can be obtained respectively. Therefore, steps S2, S3, and S4 do not necessarily have a sequential relationship.

[0067] During implementation, in step S2, the number of spring rows in each longitudinal area of the side-sleeping mattress is obtained by the following method:

[0068] S21. Divide the human body into parts, and obtain the customer's body data based on the divided parts of the human body, thereby obtaining the longitudinal dimensions of each part of the human body;

[0069] S22. Based on the longitudinal dimensions of each part of the human body, obtain the number of spring rows in each longitudinal region of the side-sleeping mattress; wherein each part of the human body corresponds to each longitudinal region of the side-sleeping mattress one-to-one.

[0070] When implementing it specifically, Figure 2 As shown, the divided parts of the human body are the head and neck, shoulders, back, waist, buttocks and thigh roots, legs and feet; the human body data includes basic human body data and detailed human body data.

[0071] Specifically, the head and neck are the longitudinal part between the top of the head and the posterior cervical vertebrae point; the shoulder is the longitudinal part of the posterior cervical vertebrae point to the midline between the scapula protrusion and the nipple point; the back is the longitudinal part of the midline between the scapula protrusion and the nipple point to the midline between the nipple point and the horizontal waistline; the waist is the longitudinal part of the midline between the nipple point and the horizontal waistline to the anterior convex point of the abdomen; the buttocks and thighs are the longitudinal part between the anterior convex point of the abdomen to the position of 0.382×(the height of the horizontal line of the lower end of the gluteal groove - the height of the midpoint of the knee); the legs and feet are the longitudinal part from the position of 0.618×(the height of the horizontal line of the lower end of the gluteal groove - the height of the midpoint of the knee) to the sole of the foot.

[0072] It should be noted that this embodiment uses 0.382 and 0.618 to divide the human body into different parts, corresponding to the buttocks and thighs, and the legs and feet, respectively. This division method makes the mattress more ergonomic and better adapted to the natural proportions of the human body, thus providing customers with a more comfortable sleeping experience.

[0073] It can be understood that the various parts of the human body divided in this embodiment can fully outline the differences in user body characteristics and are suitable for personalized matching of side-sleeping mattress springs, thereby achieving accurate body zoning.

[0074] It should be noted that, in this embodiment, taking into account the convenience and accuracy of human body data collection, two methods of obtaining human body fine data are provided, one is to obtain through three-dimensional human body scanning, and the other is to obtain through two-dimensional image recognition. Both of these acquisition methods are implemented using mature existing technologies; among them, the images are front-facing and side-facing human body photos wearing form-fitting and close-fitting clothing.

[0075] Optionally, the basic human body data is obtained by three-dimensional human body scanning, and the basic human body data includes gender, weight, and mattress hardness preference;

[0076] The detailed human body data includes height, height of the back cervical vertebrae point, height of the shoulder blade protrusion point, height of the nipple point, height of the horizontal waistline, height of the front abdominal protrusion point, height of the horizontal line of the lower end of the gluteal groove, height of the midpoint of the knee, straight-line shoulder width, straight-line hip width, and straight-line waist width.

[0077] It should be noted that the detailed human body data collection here is obtained through three-dimensional human body scanning, and the data accuracy is higher.

[0078] Therefore, in the specific implementation, in step S21, the longitudinal dimensions of each part of the human body are obtained by the following method:

[0079] The longitudinal dimension of the head and neck = height - height of the posterior cervical vertebrae;

[0080] The longitudinal dimension of the shoulder = the height of the posterior cervical vertebra - the height of the scapula protrusion + 0.5 × (the height of the scapula protrusion - the height of the nipple point);

[0081] The longitudinal dimension of the back = 0.5 × (shoulder blade height - nipple height) + 0.5 × (nipple height - horizontal waistline height);

[0082] The longitudinal dimension of the waist = 0.5 × (nipple point height - horizontal waistline height) + (horizontal waistline height - abdominal convex point height);

[0083] The longitudinal dimension of the buttocks and thigh root = (height of the anterior abdominal convex point - height of the horizontal line of the lower end of the gluteal groove) + 0.382 × (height of the horizontal line of the lower end of the gluteal groove - height of the midpoint of the knee);

[0084] The longitudinal dimension of the leg and foot = 0.618 × (height of the horizontal line at the lower end of the gluteal groove - height of the mid-point of the knee) + height of the mid-point of the knee.

[0085] Optionally, the basic human body data is obtained by two-dimensional image recognition, and includes gender, height, weight, and mattress hardness preference;

[0086] The detailed human body data includes the ratio of the longitudinal size of the head and neck to the height, the ratio of the longitudinal size of the shoulders to the height, the ratio of the longitudinal size of the back to the height, the ratio of the longitudinal size of the waist to the height, the ratio of the longitudinal size of the hips and thighs to the height, the ratio of the longitudinal size of the legs and feet to the height, the straight-line hip-to-waist width ratio, and the straight-line shoulder-to-waist width ratio.

[0087] Specifically, the heights of the top of the head, the posterior cervical vertebrae point, the scapula protrusion point, the nipple point, the horizontal waistline, the anterior abdominal convex point, the lower horizontal line of the gluteal groove, and the midpoint of the knee compared to the ground under the feet in the two-dimensional image are obtained by two-dimensional image recognition, thereby obtaining the longitudinal length of each part of the human body, and then the ratio of the longitudinal length of each part of the human body to the height between the top of the head and the ground under the feet is used as the ratio of the longitudinal size of each part of the human body to the height; at the same time, the widths of the straight shoulder width and the straight hip width are obtained by two-dimensional image recognition, and then the ratio of the widths of the straight hip width and the straight shoulder width is used as the straight hip width to shoulder width ratio.

[0088] Therefore, in specific implementation, in step S2, the longitudinal dimension of the corresponding human body part can be obtained by multiplying the body height by the ratio of the longitudinal dimension of the corresponding human body part to the body height.

[0089] It should be noted that the collection of detailed human body data here is obtained through two-dimensional image recognition, which is more convenient.

[0090] During implementation, in step S22, the method of obtaining the number of spring rows in each longitudinal area of the side-sleeping mattress based on the longitudinal dimensions of each part of the human body includes:

[0091] S221. Based on the longitudinal dimensions of each part of the human body, obtain the longitudinal dimensions of each longitudinal area of the mattress.

[0092] Specifically, the longitudinal dimensions of each longitudinal region of the mattress are obtained by:

[0093] The longitudinal dimension of the head and neck area in the mattress = max{longitudinal dimension of the human head and neck, set pillow width};

[0094] The longitudinal dimension of the shoulder area of the mattress = the longitudinal dimension of the human shoulder;

[0095] The longitudinal dimension of the back area of the mattress = the longitudinal dimension of the human back;

[0096] The longitudinal dimension of the lumbar region of the mattress = the longitudinal dimension of the human waist;

[0097] The longitudinal dimensions of the mattress's buttocks and thigh root areas = the longitudinal dimensions of a person's buttocks and thigh root areas;

[0098] The longitudinal dimensions of the longitudinal area of the legs and feet in the mattress = max{longitudinal dimensions of the human legs and feet, set standard longitudinal dimensions of the mattress - longitudinal dimensions of all other longitudinal areas in the mattress}.

[0099] Specifically, the pillow width is set according to actual needs. For example, the pillow width is set to 40 cm. It is understandable that with respect to the longitudinal dimension of the head and neck area of a side-sleeping mattress, considering that the common width of a single pillow is 35 to 40 cm, the longitudinal dimension of the head and neck of a person with a height of 195 cm is approximately 36 cm, and when using a pillow, the posterior cervical vertebra point is usually located above the lower edge of the pillow, that is, the actual longitudinal dimension of the head and neck area of the mattress is slightly smaller than the pillow width. Therefore, the size of the head and neck area of the mattress is uniformly set to 40 cm. If the width of the pillow used by the user is greater than 40 cm, the size of the head and neck area of the side-sleeping mattress can also be set to the same as the pillow width.

[0100] Specifically, the longitudinal dimension of the standard mattress is set according to needs. For example, the longitudinal dimension of the standard mattress is set to 200 cm.

[0101] S222. Based on the longitudinal dimensions of each longitudinal region of the mattress and the diameter of the selected springs, obtain the number of spring rows in each longitudinal region of the mattress.

[0102] Specifically, the number of spring rows in each longitudinal area of the mattress is obtained by dividing the longitudinal dimension of each longitudinal area of the mattress by the diameter of the selected spring and rounding the result to the integer.

[0103] More specifically, the rounding method is rounding off.

[0104] It should be noted that after rounding off to the nearest integer to determine the number of spring rows, the longitudinal dimensions of some parts of the mattress may be slightly different from the original calculated results. In this case, the mattress should be made based on the rounded number of spring rows; if the customer's height is less than or equal to the standard mattress longitudinal dimension, the mattress will be made based on the standard mattress longitudinal dimension. At this time, when the total number of spring rows is greater than or less than the number of spring rows required for the standard mattress longitudinal dimension, the mattress length will be adjusted by reducing or adding a row of springs in the longitudinal area of the legs and feet; if the customer's height exceeds the longitudinal dimension of the standard mattress, the mattress will be customized according to the customer's actual height. At this time, the mattress can be made based on the calculated number of spring rows in each longitudinal area.

[0105] Specifically, the spring is a cylindrical coil spring, and the spring diameter is selected based on actual conditions. More specifically, the spring diameter is typically selected between 5 cm and 6.5 cm. For example, the spring diameter is selected to be 6.5 cm. It should be noted that the spring edges can fit together or maintain a certain distance between them. If there are distances between the springs, when calculating the number of spring rows, the sum of the actual spring diameter and the distance between them is used as the spring diameter for calculating the number of spring rows.

[0106] During implementation, in step S3, the spring hardness levels from soft to hard include soft, medium, hard, and extra hard; the mattress hardness preference includes soft, medium, and hard; and the baseline hardness level of the mattress spring is obtained by the following method;

[0107] Based on the height and weight of the customer's body data, the customer's BMI value is obtained;

[0108] If the BMI value is less than the first threshold, the baseline hardness level of the mattress spring is soft;

[0109] If the BMI value is greater than or equal to the first threshold and less than the second threshold, then

[0110] If the customer's body data indicates a soft mattress hardness preference, the mattress spring's baseline hardness level will be soft.

[0111] If the customer's body data indicates a mattress firmness preference of medium or firm, the baseline firmness level of the mattress springs will be medium.

[0112] If the BMI value is greater than or equal to the second threshold, the baseline hardness level of the mattress spring is moderate.

[0113] Specifically, the BMI value a of the customer is obtained by the following method: BMI :

[0114]

[0115] Specifically, the unit of weight is kilograms and the unit of height is meters.

[0116] Specifically, the first threshold is 22 and the second threshold is 26.

[0117] Specifically, in this embodiment, spring hardness level 1 is set as extra-hard, labeled FF; spring hardness levels 2-3 are set as hard, labeled F; spring hardness levels 4-6 are set as moderate, labeled M; and spring hardness levels 7-9 are set as soft, labeled S. It is understood that the light industry standard QB / T 1952.2-2023, "Soft Furniture Spring Mattresses," uses numerical hardness scales from 1 to 10 to represent spring hardness levels, with smaller numbers representing harder springs and larger numbers representing softer springs.

[0118] Preferably, in this embodiment, the baseline hardness gear of the soft gear selects a hardness level of 8, and the allowable error range is -0.4 to 0.4; the baseline hardness gear of the moderate gear selects a hardness level of 5, and the allowable error range is -0.4 to 0.4; the baseline hardness gear of the hard gear selects a hardness level of 2, and the allowable error range is -0.4 to 0.4.

[0119] During implementation, in step S4, the spring hardness gradient pattern corresponding to the maximum value among the spring hardness gradient pattern discrimination function values is taken as the optimal spring hardness gradient pattern.

[0120] In specific implementation, the pattern discrimination model is expressed as:

[0121]

[0122] Where p i represents the discriminant function value of the i-th spring hardness gradient mode, g i 、g i′ They represent the reference values of the i-th and i′-th spring hardness gradient modes respectively, and I represents the total number of spring hardness gradient modes.

[0123] It should be noted that this embodiment designs the spring hardness distribution in each longitudinal area of the mattress based on the comfort and support requirements of people with different body shapes when lying on their side, forming three spring hardness gradient patterns.

[0124] Specifically, the spring hardness gradient modes of the side-sleeping mattress include CA mode, CB mode and CC mode;

[0125] like Figure 3 As shown, the CA mode is that the spring hardness level of the shoulder area is two levels softer than that of the head and neck area; the spring hardness level of the back area is one level harder than that of the shoulder area; the spring hardness level of the waist area is the same as that of the back area; the spring hardness level of the buttocks and thigh root area is one level softer than that of the waist area; the spring hardness level of the leg and foot area is one level harder than that of the buttocks and thigh root area; wherein the spring hardness level of the shoulder area is the baseline hardness level;

[0126] like Figure 4 As shown, the CB mode is that the spring hardness level of the shoulder area is one level softer than that of the head and neck area; the spring hardness level of the back area is the same as that of the shoulder area; the spring hardness level of the waist area is one level harder than that of the back area; the spring hardness level of the buttocks and thigh root area is one level softer than that of the waist area; the spring hardness level of the leg and foot area is one level harder than that of the buttocks and thigh root area; wherein the spring hardness level of the shoulder area is the baseline hardness level;

[0127] like Figure 5As shown, the CC mode is that the spring hardness level of the shoulder area is one level softer than that of the head and neck area; the spring hardness level of the back area is the same as that of the shoulder area; the spring hardness level of the waist area is the same as that of the back area; the spring hardness level of the buttocks and thigh root area is one level softer than that of the waist area; the spring hardness level of the leg and foot area is one level harder than that of the buttocks and thigh root area; wherein, the spring hardness level of the buttocks and thigh root area is the baseline hardness level.

[0128] Specifically, the reference values g1, g2, and g3 of the CA mode, CB mode, and CC mode are respectively expressed as:

[0129] g1=0

[0130] g2=12.219-5.019×s+0.547×a BMI +0.703×q1-17.921×q2

[0131] g3=17.036-5.426×s+0.231×a BMI +0.155×q1-14.769×q2

[0132] In the formula, s represents the gender of the customer, which takes the value of 0 or 1, where 0 represents female and 1 represents male; a BMI Indicates the customer's BMI value; q1 indicates the linear shoulder width to waist width ratio, and q2 indicates the linear hip width to waist width ratio.

[0133] Specifically, if the detailed data of the human body is obtained by three-dimensional human body scanning, the linear hip-to-waist width ratio q2 = linear hip width / linear shoulder width, and the linear shoulder-to-waist width ratio q1 = linear shoulder width / linear waist width; if the detailed data of the human body is obtained by two-dimensional image recognition, the linear hip-to-waist width ratio and the linear shoulder-to-waist width ratio can be directly obtained.

[0134] Compared with the existing technology, the method for making a personalized side-sleeping mattress provided in this embodiment fully considers the individual differences of customers in body characteristics and softness and hardness preferences when sleeping on their side, and determines the number of springs arranged in each zone of the side-sleeping mattress according to the longitudinal dimensions of each part of the customer's body; determines the baseline hardness level springs with the minimum hardness required for the side-sleeping mattress according to the BMI value and the mattress hardness preference; and determines the spring hardness gradient of each zone of the side-sleeping mattress according to the body characteristics; in this way, a personalized mattress suitable for side-sleeping posture and meeting their body characteristics and hardness preferences is customized for the customer, thereby improving the individual's sleep quality and providing forward-looking production planning for mattress companies.

[0135] Example 2

[0136] The present invention provides a specific embodiment 2, which is used to illustrate the specific process of the method for making a personalized side-sleeping mattress provided in embodiment 1.

[0137] Scenario 1: Male, weighing 68.36 kg, with a mattress preference of medium firmness. Detailed body data was obtained through a 3D body scan: height 175.00 cm, cervical vertebrae height 147.40 cm, shoulder blade protrusion height 131.30 cm, nipple point height 124.40 cm, horizontal waistline height 106.50 cm, abdominal protrusion height 99.00 cm, gluteal groove height 79.10 cm, mid-knee height 45.40 cm, straight shoulder width 38.30 cm, straight waist width 29.30 cm, and straight hip width 33.60 cm.

[0138] like Figure 2 As shown, the human body is divided into six regions: head and neck, shoulders, back, waist, buttocks and thighs, and legs and feet. Given the availability of accurate human body data through 3D body scanning, the longitudinal dimensions of different body parts are calculated using the method provided in Example 1: 27.60 cm for the head and neck, 19.55 cm for the shoulders, 12.40 cm for the back, 16.45 cm for the waist, 32.77 cm for the buttocks and thighs, and 66.23 cm for the legs and feet.

[0139] In this embodiment, the longitudinal dimension of the head and neck is 27.60 cm, and the pillow width is 40 cm. Therefore, the longitudinal dimension of the head and neck area of the mattress is uniformly set at 40 cm. The longitudinal dimensions of the shoulder, back, waist, hip, and thigh areas of the customized side-sleeping mattress are directly calculated based on the corresponding body parts: 19.55 cm for the shoulder, 12.40 cm for the back, 16.45 cm for the waist, and 32.77 cm for the hip and thigh. Since the leg and foot areas of the mattress extend to the foot of the mattress, the leg and foot areas are set at 78.83 cm for a standard 200 cm mattress.

[0140] Dividing the above values by the planned spring diameter of 6.50 cm for the custom mattress, we find that the mattress has six rows of springs in the head and neck area, three rows in the shoulders, two rows in the back, three rows in the waist, five rows in the hip and thigh areas, and 12 rows in the legs and feet. This totals to 31 rows, so the number of rows in the legs and feet doesn't need to be adjusted.

[0141] Calculation shows that the customer's BMI value in this scenario is 22.32, which is between 22.0 and 26.0. The baseline spring hardness level can be selected as soft or medium. Since the customer prefers a mattress with moderate hardness, the medium level is selected, that is, the spring hardness level is selected as 5.0±0.4, and the soft and hard cylindrical coil spring is moderate.

[0142] Based on the detailed human body data obtained from three-dimensional human body scanning, the straight hip width is 33.60cm, the straight shoulder width is 38.30cm, and the straight waist width is 29.30cm. From this, it can be calculated that the straight hip width to waist width ratio is 1.1468, and the straight shoulder width to waist width ratio is 1.3072.

[0143] Based on the customer's gender value of 1, BMI value of 22.32, straight hip-to-waist width ratio of 1.1468, and straight shoulder-to-waist width ratio of 1.3072 in scenario 1, the discriminant function value of the spring hardness gradient pattern of the side-sleeping mattress is obtained. The calculated pattern discriminant function value p1 is approximately 0.4020, p2 is approximately 0.3214, and p3 is approximately 0.2766. Therefore, the spring hardness gradient pattern CA mode is selected as the optimal spring hardness gradient pattern.

[0144] Taking the customer in scenario 1 as an example, the summary of the judgment results is as follows:

[0145] The mattress has 6 rows of springs in the longitudinal area of the head and neck, 3 rows of springs in the longitudinal area of the shoulders, 2 rows of springs in the longitudinal area of the back, 3 rows of springs in the longitudinal area of the waist, 5 rows of springs in the longitudinal area of the buttocks and thighs, and 12 rows of springs in the longitudinal area of the legs and feet; the baseline hardness level is moderate, and springs with a hardness level of 5.0±0.4 are selected; the spring hardness gradient mode is selected as CA mode; as shown in Table 1, the 1st to 6th rows of springs of the mattress correspond to the head and neck area, with a hardness level of F; the 7th to 9th rows of springs correspond to the shoulder area, with a hardness level of M; the 10th to 11th rows of springs correspond to the back area, with a hardness level of F; the 12th to 14th rows of springs correspond to the waist area, with a hardness level of FF; the 15th to 19th rows of springs correspond to the buttocks and thighs area, with a hardness level of M; the 20th to 31st rows of springs correspond to the legs and feet area, with a hardness level of F.

[0147]

[0148] Scenario 2: A female, 166.00 cm tall, 60.50 kg in weight, preferring a soft mattress. Frontal and side profile photos of the female wearing form-fitting clothing were taken and uploaded using a mobile phone. A sophisticated method for automatically extracting human dimensions based on 2D images was then used to extract the longitudinal dimensions of key body parts relative to their height. The longitudinal dimensions of the head and neck accounted for 16.02% of the height, the shoulders for 9.58%, the back for 8.40%, the waist for 9.61%, the hips and thighs for 19.69%, and the legs and feet for 36.70%. The straight-line shoulder-to-waist ratio was 1.5058, and the straight-line hip-to-waist ratio was 1.4163.

[0149] By multiplying the customer's height of 166.00 cm in Scenario 2 by the key human body longitudinal proportion extraction values extracted through image recognition, we can obtain: the longitudinal dimension of the head and neck is 26.60 cm, the longitudinal dimension of the shoulder is 15.90 cm, the longitudinal dimension of the back is 13.95 cm, the longitudinal dimension of the waist is 15.95 cm, the longitudinal dimension of the buttocks and thigh roots is 32.68 cm, and the longitudinal dimension of the legs and feet is 60.92 cm.

[0150] The longitudinal dimension of the head and neck is 26.60cm, and the pillow width is 40cm. Therefore, the longitudinal dimension of the head and neck in the mattress is set to 40cm. The longitudinal dimensions of the shoulders, back, waist, hips, and thighs in the customized side sleeper mattress are directly calculated based on the corresponding longitudinal dimensions of the body parts: 15.90cm for the shoulders, 13.95cm for the back, 15.95cm for the waist, and 32.68cm for the hips and thighs. The leg and foot areas extend to the end of the mattress; for a standard 200cm mattress, the leg and foot areas are set to 81.52cm.

[0151] Dividing the above values by the planned spring diameter of 6.50 cm for the custom side sleeper mattress yields: 6 rows of springs in the head and neck area, 2 rows in the shoulders, 2 rows in the back, 2 rows in the waist, 5 rows in the hip and thigh areas, and 13 rows in the legs and feet. This results in a total of 30 rows, which is less than the 31 required for a standard mattress. This requires adding a row of leg and foot springs at the foot of the bed to adjust the mattress length. This adjustment results in 6 rows of springs in the head and neck area, 2 rows in the shoulders, 2 rows in the back, 2 rows in the waist, 5 rows in the hip and thigh areas, and 14 rows in the legs and feet.

[0152] The calculated BMI for this scenario is 21.96, which is less than 22.0. The baseline hardness setting can be set to soft, and a relatively soft cylindrical coil spring with a hardness of 8.0 ± 0.4 is recommended.

[0153] Detailed human body data was obtained through two-dimensional image extraction. After image recognition, the linear shoulder-to-waist ratio was 1.5058, and the linear hip-to-waist ratio was 1.4163. In scenario 2, the customer's gender was set to 0, BMI was 21.96, and the linear shoulder-to-waist ratio was 1.5058 and 1.4163, respectively. We obtained p1 of approximately 0.2213, p2 of approximately 0.2020, and p3 of approximately 0.5767. The CC spring hardness gradient mode was selected as the optimal spring hardness gradient mode:

[0154] Taking the customer in scenario 2 as an example, the summary of the judgment results is as follows:

[0155] The mattress has 6 rows of springs in the longitudinal area of the head and neck, 2 rows of springs in the longitudinal area of the shoulders, 2 rows of springs in the longitudinal area of the back, 2 rows of springs in the longitudinal area of the waist, 5 rows of springs in the longitudinal area of the buttocks and thighs, and 14 rows of springs in the longitudinal area of the legs and feet; the baseline hardness level is moderate, and relatively soft springs with a hardness level of 8.0±0.4 are selected; the spring hardness gradient mode is selected as CC mode; as shown in Table 2, the 1st to 6th rows of springs of the mattress correspond to the head and neck area, with a hardness level of F; the 7th to 8th rows of springs correspond to the shoulder area, with a hardness level of M; the 9th to 10th rows of springs correspond to the back area, with a hardness level of M; the 11th to 12th rows of springs correspond to the waist area, with a hardness level of M; the 13th to 17th rows of springs correspond to the buttocks and thighs area, with a hardness level of S; the 18th to 31st rows of springs correspond to the legs and feet area, with a hardness level of M.
