Description

Technical Field

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

[0002] Nearly one-third of our lives are spent in bed. Mattresses not only affect sleep quality but also have a direct impact on physical health. Choosing a personalized mattress that suits your body shape and sleeping preferences, and provides precise support for different parts of the body during sleep, is crucial for improving sleep quality and maintaining good health. A mattress structure is generally divided into a support layer, a cushioning layer, and a fabric composite layer. These layers form a superimposed whole and together determine the mechanical properties of the mattress and its support characteristics for the human body. The support layer is a crucial factor in determining the overall support performance of the mattress. Among the materials used for the mattress support layer, spring bed nets are one of the most technologically mature and reliable options. By optimizing the layout of the mattress springs, the overall mechanical properties of the mattress can be improved, allowing it to better accommodate consumers' body shapes and firmness preferences.

[0003] Most mattresses currently on the market use a universal design and are not specifically optimized for different sleeping positions. However, different sleeping positions lead to significant differences in the pressure distribution and support requirements of the human spine. Sleeping on your back is one of the most natural sleeping positions for the human body. It allows the spine to maintain its natural physiological curvature, ensuring relatively even pressure distribution across the body, which helps improve sleep quality. Given the unique advantages of the supine position, developing a mattress specifically adapted for this position has significant health and market value.

[0004] Furthermore, while the single-size, zoned mattresses currently on the market claim to have different zoned designs, they are in fact still based on a "one-size-fits-all" manufacturing philosophy, attempting to adapt a fixed design to everyone's body characteristics. This approach ignores ergonomic principles and fails to consider individual differences in height, weight, body shape, and firmness preferences. Therefore, although these mattresses are nominally "zoned," they actually cannot provide personalized optimal body support for each person and are, to a certain extent, a "pseudo-zoned" mattress.

[0005] Therefore, there is an urgent need for a method for making a personalized supine mattress that is tailored to the customer's anatomy and hardness preferences. Summary of the Invention

[0006] In view of the above analysis, the embodiments of the present invention aim to provide a method for manufacturing a personalized mattress suitable for supine sleeping position, so as to solve the problem that existing mattresses cannot meet the personalized needs of customers' anatomy characteristics and hardness preferences.

[0007] An embodiment of the present invention provides a method for making a personalized mattress suitable for a supine sleeping position, comprising the following steps:

[0008] 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;

[0009] Based on the longitudinal dimensions of each part of the human body, the number of spring rows in each longitudinal area of the mattress is obtained; wherein each part of the human body corresponds to each longitudinal area of the mattress;

[0010] Based on the acquired customer's body data and the set spring hardness level, a baseline hardness level of the mattress spring is obtained;

[0011] Based on the customer's anatomy data, the set spring hardness gradient patterns, and the pattern discrimination model, the optimal spring hardness gradient pattern is obtained; wherein the spring hardness gradient pattern is the relationship between the spring hardness of different areas of the mattress;

[0012] 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, the customer can get a personalized mattress suitable for supine sleeping position.

[0013] Optionally, the divided parts of the human body are the head and neck, shoulders, back, waist, buttocks and thigh roots, legs and feet;

[0014] The human body data includes basic human body data and detailed human body data;

[0015] The basic human data includes gender, weight, and mattress firmness preference;

[0016] 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, and straight-line hip width.

[0017] Furthermore, the longitudinal dimensions of each part of the human body are obtained by:

[0018] The longitudinal dimension of the head and neck = height - height of the posterior cervical vertebrae;

[0019] 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);

[0020] The longitudinal dimension of the back = 0.5 × (shoulder blade height - nipple height) + 0.5 × (nipple height - horizontal waistline height);

[0021] The longitudinal dimension of the waist = 0.5 × (nipple point height - horizontal waistline height) + (horizontal waistline height - abdominal convex point height);

[0022] 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);

[0023] 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.

[0024] Optionally, the divided parts of the human body are the head and neck, shoulders, back, waist, buttocks and thigh roots, legs and feet;

[0025] The human body data includes basic human body data and detailed human body data;

[0026] The basic human data includes gender, age, height, weight, and mattress hardness preference;

[0027] 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 thigh roots to the height, the ratio of the longitudinal size of the legs and feet to the height, and the straight-line hip width to shoulder width ratio.

[0028] Furthermore, the number of spring rows in each longitudinal area of the mattress is obtained by the following method:

[0029] Based on the longitudinal dimensions of each part of the human body, the longitudinal dimensions of each longitudinal area of the mattress are obtained;

[0030] Based on the longitudinal dimensions of each longitudinal area of the mattress and the diameter of the selected springs, the number of rows of springs in each longitudinal area of the mattress is obtained.

[0031] Furthermore, the spring hardness levels include soft, medium and hard from soft to hard; the mattress hardness preference includes soft, medium and hard; the baseline hardness level of the mattress spring is obtained by the following method;

[0032] Based on the height and weight of the customer's body data, the customer's BMI value is obtained;

[0033] If the BMI value is less than the first threshold, the baseline hardness level of the mattress spring is soft;

[0034] If the BMI value is greater than or equal to the first threshold and less than the second threshold, then

[0035] If the customer's body data indicates a soft mattress hardness preference, the mattress spring's baseline hardness level will be soft.

[0036] 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.

[0037] If the BMI value is greater than or equal to the second threshold, the baseline hardness level of the mattress spring is moderate.

[0038] Furthermore, the spring hardness gradient mode includes a YA mode and a YB mode;

[0039] The YA mode is that the spring hardness gear of the shoulder area is one gear softer than the spring hardness gear of the head and neck area; the spring hardness gear of the back area is the same as the spring hardness gear of the shoulder area; the spring hardness gear of the waist area is one gear harder than the spring hardness gear of the back area; the spring hardness gear of the buttocks and thigh root area is one gear softer than the spring hardness gear of the waist area; the spring hardness gear of the leg and foot area is one gear harder than the spring hardness gear of the buttocks and thigh root area; wherein the spring hardness gear of the shoulder area is the baseline hardness gear;

[0040] The YB 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 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; among which, the spring hardness level of the shoulder area is the baseline hardness level.

[0041] Furthermore, the optimal spring hardness gradient pattern is obtained by:

[0042] Based on the customer's human body data and the pattern discrimination model, a pattern discrimination function value is obtained;

[0043] If the mode function value is greater than the set mode threshold, the YA mode is used as the optimal spring hardness gradient mode;

[0044] Otherwise, the YB mode is used as the optimal spring hardness gradient mode.

[0045] Furthermore, the pattern discrimination model is:

[0046]

[0047] Where p represents the value of the pattern discriminant function, s represents the gender of the customer, and takes the value of 0 or 1, where 0 represents female and 1 represents male; a BMI represents the client's BMI value; q represents the straight-line hip-to-shoulder width ratio.

[0048] Furthermore, the first threshold is 22 and the second threshold is 24.

[0049] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:

[0050] The present invention provides a method for producing a personalized mattress suitable for supine sleeping position, which fully considers the individual differences of mattress users in body characteristics and softness and hardness preferences. The number of springs arranged in each partition of the mattress is determined according to the longitudinal dimensions of each part of the customer's body; the baseline hardness level springs with the minimum hardness required for the supine mattress are determined according to the BMI value and the mattress hardness preference; and the spring hardness gradient of each partition of the supine mattress is determined according to the body characteristics. In this way, a personalized mattress that is precisely adapted to the user's body characteristics and hardness preferences is obtained, achieving more scientific sleep support, improving sleep quality, and providing forward-looking production planning for mattress companies.

[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 mattress suitable for supine sleeping position, such as Figure 1 As shown, the following steps are included:

[0060] S1. Divide the human body into parts, and based on the divided parts, obtain the customer's body data, and then obtain the longitudinal dimensions of each part of the body;

[0061] S2. Based on the longitudinal dimensions of each part of the human body, obtaining the number of spring rows in each longitudinal region of the mattress; wherein each part of the human body corresponds to each longitudinal region of the mattress;

[0062] S3. Obtaining a baseline hardness level of the mattress springs based on the acquired customer body data and the set spring hardness level;

[0063] S4. Based on the customer's anatomy data, the set spring hardness gradient patterns, and the pattern discrimination model, an optimal spring hardness gradient pattern is obtained; wherein the spring hardness gradient pattern represents the spring hardness relationship between different areas of the 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 suitable for the customer's supine sleeping position is obtained.

[0065] It is understood that the personalized mattress production method in this embodiment is applicable to both single and double mattresses. For double mattresses, corresponding mattress units can be manufactured based on the individual characteristics of the two customers and then assembled together to achieve personalized customization. Furthermore, this embodiment is designed and optimized primarily for supine sleeping, providing a more comfortable sleeping experience for those sleeping in that position. However, it should be noted that this mattress is also suitable for other sleeping positions, though the comfort in these positions may be slightly lower than that for supine sleeping.

[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 S1, if 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.

[0068] 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.

[0069] 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.

[0070] 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 supine mattress springs, thereby achieving accurate body zoning.

[0071] 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.

[0072] 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;

[0073] 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, and straight-line hip width.

[0074] 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.

[0075] Therefore, in the specific implementation, in step S1, the longitudinal dimensions of each part of the human body are obtained by the following method:

[0076] The longitudinal dimension of the head and neck = height - height of the posterior cervical vertebrae;

[0077] 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);

[0078] The longitudinal dimension of the back = 0.5 × (shoulder blade height - nipple height) + 0.5 × (nipple height - horizontal waistline height);

[0079] The longitudinal dimension of the waist = 0.5 × (nipple point height - horizontal waistline height) + (horizontal waistline height - abdominal convex point height);

[0080] 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);

[0081] 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.

[0082] Optionally, the basic human body data is obtained by two-dimensional image recognition, and includes gender, height, weight, and mattress hardness preference;

[0083] 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 thigh roots to the height, the ratio of the longitudinal size of the legs and feet to the height, and the straight-line hip width to shoulder width ratio.

[0084] Specifically, the heights of the top of the head, the posterior cervical vertebra point, the scapula protrusion point, the nipple point, the horizontal waistline, the anterior abdominal protrusion point, the lower horizontal line of the gluteal groove, and the midpoint of the knee relative 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.

[0085] Therefore, in specific implementation, in step S1, 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.

[0086] It should be noted that the detailed data collection of the human body here is obtained through two-dimensional image recognition, which is more convenient.

[0087] During implementation, in step S2, the number of spring rows in each longitudinal area of the mattress is obtained by the following method:

[0088] S21. Based on the longitudinal dimensions of each part of the human body, obtain the longitudinal dimensions of each longitudinal area of the mattress.

[0089] Specifically, the longitudinal dimensions of each longitudinal region of the mattress are obtained by:

[0090] The longitudinal dimension of the head and neck area in the mattress = max{longitudinal dimension of the human head and neck, set pillow width};

[0091] The longitudinal dimension of the shoulder area of the mattress = the longitudinal dimension of the human shoulder;

[0092] The longitudinal dimension of the back area of the mattress = the longitudinal dimension of the human back;

[0093] The longitudinal dimension of the lumbar region of the mattress = the longitudinal dimension of the human waist;

[0094] The longitudinal dimensions of the mattress's buttocks and thigh root areas = the longitudinal dimensions of a person's buttocks and thigh root areas;

[0095] 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}.

[0096] Specifically, the pillow width is set according to actual needs. For example, the pillow width is set to 40 cm. It is understandable that regarding the longitudinal dimension of the head and neck area of a supine 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 mattress head and neck area is slightly smaller than the pillow width. Therefore, the size of the mattress head and neck area 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 supine mattress head and neck area can also be set to the same as the pillow width.

[0097] 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.

[0098] S22. 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.

[0099] 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.

[0100] More specifically, the rounding method is rounding off.

[0101] 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 in longitudinal dimension 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 of the mattress.

[0102] Specifically, the spring is a cylindrical coil spring, and the diameter of the spring is selected according to the actual situation. More specifically, the spring diameter is usually selected between 5cm and 6.5cm. For example, the spring diameter is selected to be 6.5cm. It should be noted that the edges of the springs can fit together or maintain a certain distance; if there is a distance between the springs, when calculating the number of spring rows, the sum of the actual spring diameter and the distance is used as the spring diameter when calculating the number of spring rows.

[0103] During implementation, in step S3, the spring hardness levels from soft to hard include soft, medium and hard; the mattress hardness preference includes soft, medium and hard; the baseline hardness level of the mattress spring is obtained by the following method;

[0104] Based on the height and weight of the customer's body data, the customer's BMI value is obtained;

[0105] If the BMI value is less than the first threshold, the baseline hardness level of the mattress spring is soft;

[0106] If the BMI value is greater than or equal to the first threshold and the second threshold, then

[0107] If the customer's mattress hardness preference is soft in their body data, the baseline hardness level of the mattress spring will be soft;

[0108] If the customer's body data indicates a mattress firmness preference of medium or firm, the mattress spring's baseline firmness level will be medium.

[0109] If the BMI value is greater than or equal to the second threshold, the baseline hardness level of the mattress spring is moderate.

[0110] Specifically, the BMI value a of the customer is obtained by the following method: BMI :

[0111]

[0112] Specifically, the unit of weight is kilograms and the unit of height is meters.

[0113] Specifically, the first threshold is 22 and the second threshold is 24.

[0114] Specifically, in this embodiment, spring hardness levels 1 to 3 are considered hard and are labeled F; spring hardness levels 4 to 6 are considered medium and are labeled M; and spring hardness levels 7 to 9 are considered soft and are 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.

[0115] 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.

[0116] It should be noted that, in this embodiment, the spring hardness distribution in each longitudinal area of the mattress is designed based on the comfort and support requirements of people with different body shapes when lying on their backs, forming two spring hardness gradient patterns.

[0117] When implemented, the mattress spring hardness gradient modes suitable for supine sleeping position include YA mode and YB mode;

[0118] like Figure 3 As shown, the YA 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;

[0119] like Figure 4 As shown, the YB 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 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.

[0120] During implementation, in step S3, the pattern discrimination model is:

[0121] If the mode function value is greater than the set mode threshold, the YA mode is used as the optimal spring hardness gradient mode;

[0122] Otherwise, the YB mode is taken as the optimal spring hardness gradient mode.

[0123] Specifically, the mode threshold is set to 0.5.

[0124] In specific implementation, the pattern discrimination function value p is expressed as:

[0125]

[0126] 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 represents the client's BMI value; q represents the straight-line hip-to-shoulder width ratio.

[0127] Specifically, if the human body fine data is obtained by three-dimensional human body scanning, the straight-line hip-shoulder width ratio q = straight-line hip width / straight-line shoulder width; if the human body fine data is obtained by two-dimensional image recognition, the straight-line hip-shoulder width ratio is directly obtained.

[0128] Compared with the prior art, the method for making a personalized mattress suitable for supine sleeping position provided in this embodiment fully considers the individual differences of mattress users in terms of body characteristics and softness and hardness preferences, and determines the number of springs arranged in each zone of the 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 supine mattress according to the BMI value and the mattress hardness preference; and determines the spring hardness gradient of each zone of the supine mattress according to the body characteristics; in this way, a personalized mattress suitable for supine sleeping position and meeting their body characteristics and hardness preferences is customized for the customer, thereby improving sleep quality and providing forward-looking production planning for mattress companies.

[0129] Example 2

[0130] The present invention provides a specific embodiment 2 for illustrating the specific process of the personalized mattress manufacturing method provided in embodiment 1.

[0131] Scenario 1: Male, weight 68.36 kg, mattress firmness preference. Detailed body data obtained through 3D body scanning: height 175.00 cm, cervical vertebra 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 lower horizontal height 79.10 cm, knee mid-height 45.40 cm, straight shoulder width 38.30 cm, straight back width 35.70 cm, straight chest width 29.70 cm, straight waist width 29.30 cm, and straight hip width 33.60 cm.

[0132] 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 calculation method provided in Example 1 yields the following longitudinal dimensions for different body parts: 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.

[0133] 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 shoulders, back, waist, buttocks, and thighs of the customized supine mattress are directly calculated based on the actual longitudinal dimensions of the corresponding body parts: 19.55 cm for shoulders, 12.40 cm for back, 16.45 cm for waist, and 32.77 cm for buttocks and thighs. Because the leg and foot areas of the mattress extend to the rear of the mattress, the leg and foot areas are set at 78.83 cm for a standard 200 cm mattress.

[0134] 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.

[0135] Calculation shows that the customer's BMI value in this scenario is 22.32, which is between 22.0 and 24.0. 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, a cylindrical coil spring with a spring hardness level of 5.0±0.4 and moderate hardness.

[0136] According to the detailed human body data obtained from three-dimensional human body scanning, the straight-line hip width is 33.60cm and the straight-line shoulder width is 38.30cm. From this, it can be calculated that the straight-line hip-to-shoulder width ratio is 0.8773.

[0137] The customer's gender value of 1, BMI value of 22.32, and straight hip-to-shoulder width ratio value of 0.8773 in scenario 1 are substituted into the mattress spring hardness gradient pattern discriminant function in the supine sleeping position. The calculated pattern discriminant function value p is approximately 0.5363, which is greater than the set pattern threshold of 0.5. The spring hardness gradient pattern YA mode is selected as the optimal spring hardness gradient pattern.

[0138] Taking the customer in scenario 1 as an example, the summary of the judgment results is as follows:

[0139] 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 YA 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 M; the 12th to 14th rows of springs correspond to the waist area, with a hardness level of F; 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.

[0141]

[0142] Scenario 2: A female, 166.00 cm tall, 60.50 kg in weight, preferring a soft mattress. Photos of the woman wearing form-fitting clothing were taken and uploaded using a mobile phone. A sophisticated method for automatically extracting body dimensions based on two-dimensional 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 hip-to-shoulder width ratio was 0.9406.

[0143] 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.

[0144] 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 of the customized supine 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.

[0145] Dividing the above values by the 6.50cm spring diameter of the custom mattress for supine sleepers 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 rows 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's 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.

[0146] 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.

[0147] Based on the detailed human body data extracted from the two-dimensional image, the linear hip-to-shoulder width ratio is 0.9406. Substituting the gender value of 0, BMI value of 21.96, and linear hip-to-shoulder width ratio value of 0.9406 from scenario 2 into the mattress spring hardness gradient pattern discriminant function for the supine sleeping position, the calculated pattern discriminant function value p is approximately 0.918, which is greater than the set pattern threshold of 0.5. The YA spring hardness gradient pattern is selected as the optimal spring hardness gradient pattern:

[0148] Taking the customer in scenario 2 as an example, the summary of the judgment results is as follows:

[0149] 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 YA 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 M; the 7th to 8th rows of springs correspond to the shoulder area, with a hardness level of S; the 9th to 10th rows of springs correspond to the back area, with a hardness level of S; 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.
