Description

Technical Field

[0001] This invention relates to the field of sleep support technology, and in particular to a method for determining human waist length and a mattress zoning method. Background Technology

[0002] With increasing public concern about healthy sleep, mattress design is no longer solely focused on appearance and basic sleep functions, but also increasingly emphasizes ergonomic design to improve sleep quality. Among these, zoned mattresses are gaining popularity due to their ability to provide different support for different body parts. Their design philosophy is based on the natural curve of the human spine and the varying pressure requirements of different areas. By providing targeted support in zones, they improve spinal alignment, reduce tossing and turning, and ultimately enhance sleep comfort and health.

[0003] When designing a zoned mattress, the specific length of each support zone is a key design parameter.

[0004] Some national standard documents (such as "Anthropometric Dimensions of Chinese Minors" and "Anthropometric Dimensions of Chinese Adults") provide some static anthropometric dimensions for reference. Theoretically, the width dimensions of each support zone can be determined by referring to the above national standard documents, thereby completing the design of the zoned mattress.

[0005] Taking "Anthropometric Dimensions of Chinese Minors" as an example, see... Figure 1 The standard document provides the static anthropometric dimensions for minors, including: height, shoulder height, perineal height, anterior superior iliac spine height, and upper arm length.

[0006] For example, see "Anthropometric Dimensions of Chinese Adults". Figure 2 The standard document provides the static anthropometric dimensions for adults, including: height, shoulder height, upper arm length, perineum height, thigh length, and tibialis point height.

[0007] Among them, the static human body dimensions such as height, shoulder height, perineal height, anterior superior iliac spine height, upper arm length, thigh length, and tibia height do not require complex technical means such as X-ray imaging. They can be directly obtained by simple measurement on the human body surface and belong to "directly measurable body surface dimensions".

[0008] The lumbar region usually refers to the location of the lumbar vertebrae, that is, from the first lumbar vertebra L1 to the fifth lumbar vertebra L5. The first lumbar vertebra L1 and the fifth lumbar vertebra L5 are both internal structural features of the human body and cannot be directly obtained by simple measurement on the human body surface. Therefore, the waist length of the human body cannot be directly obtained through existing national standard documents.

[0009] Since the human waist length cannot be directly obtained, the current method for determining the zoning dimensions of zoned mattresses often involves first determining the lengths of the head zone, back zone, and leg zone based on static human body dimensions, and then using the remaining space as the lumbar zone. In other words, the width of the lumbar zone is determined last, and its matching degree with the actual waist length is low. As a result, the comfort of the lumbar support provided by the zoned mattress determined in this way is also poor.

[0010] In fact, when providing support for different parts of the body during sleep, lumbar support is the most crucial. Therefore, the final design method for determining the length of the lumbar region is extremely unreasonable.

[0011] Therefore, it is necessary to develop a method for determining the waist length of the human body based on static human body dimensions, so as to provide a reference for mattress zoning design and thus improve the comfort of sleep support.

[0012] The above information is provided as background information only to aid in understanding this disclosure and does not constitute an assertion or admission that any of the above content can be used as prior art relative to this disclosure. Summary of the Invention

First, the distance dimension A corresponding to the length dimension of n lumbar vertebrae is determined by existing static human body dimensions. Then, the waist length dimension of the five lumbar vertebrae is determined according to the distance dimension A and the number of lumbar vertebrae n. Thus, the waist length dimension not explicitly stated in the prior art can be calculated, so as to provide a reference for mattress partitioning design and improve the comfort of sleep support.

[0074] Example 1

[0075] Please refer to the attached document. Figure 3 This is a flowchart illustrating a method for determining the waist length of a human body according to an embodiment of the present invention. This method is applicable to scenarios requiring the acquisition of waist length dimensions (from the thoracolumbar vertebrae dividing line to the end position of the fifth lumbar vertebra, L5). It can determine the waist length of a human body based on static human body dimensions, providing a reference for mattress zoning design and thus improving the comfort of sleep support. The method specifically includes the following steps:

[0076] S101: Obtain several static human body dimensions;

[0077] In this embodiment, several static human body dimensions can be obtained from the "Anthropometric Dimensions of Chinese Minors" and / or the "Anthropometric Dimensions of Chinese Adults"; wherein, the static human body dimensions include at least one of height, shoulder height, perineal height, anterior superior iliac spine height, upper arm length, thigh length, and tibial point height.

[0078] Specifically,

[0079] The static body dimensions of minors that can be directly obtained from "Anthropometric Dimensions of Chinese Minors" include: height, shoulder height, perineal height, anterior superior iliac spine height, and upper arm length.

[0080] The static anthropometric measurements of adults that can be directly obtained from "Chinese Adult Anthropometric Measurements" include: height, shoulder height, upper arm length, perineum height, thigh length, and tibialis point height.

[0081] It should be noted that when obtaining static anthropometric dimensions from "Anthropometric Dimensions of Chinese Minors" and "Anthropometric Dimensions of Chinese Adults", only the 50th percentile (P50) value can be taken. This is because the 50th percentile (P50) size is usually used as a representative of "average" or "medium" size. Designing a zoning system based on P50 data is beneficial to ensure that the resulting zoning is suitable for individuals of "average height" in most populations.

[0082] S102: Based on the static human body dimensions described above, calculate the distance A from the elbow joint to the termination position of the fifth lumbar vertebra L5;

[0083] For minors, the following is based on the "Anthropometric Dimensions of Chinese Minors": Distance dimension A = shoulder height - upper arm length - height of the anterior superior iliac spine;

[0084] For adults, the following is based on the "Anthropometric Dimensions of Chinese Adults": Distance dimension A = shoulder height - upper arm length - (thigh length + tibia point height).

[0085] S103: Determine the number of lumbar vertebrae n contained in the distance from the elbow joint to the termination position of the fifth lumbar vertebra L5;

[0086] The human spine has 12 thoracic vertebrae and 5 lumbar vertebrae. Anatomically, the termination position of the 12th thoracic vertebra T12 is defined as the dividing point between the thoracic and lumbar vertebrae (thoracolumbar dividing line). Therefore, the total length of the 12 thoracic vertebrae is defined as the shoulder and back length, and the length of the 5 lumbar vertebrae is defined as the waist length dimension.

[0087] When conducting anthropometric measurements, the standard document referenced in "Anthropometric Dimensions of Chinese Minors" and "Anthropometric Dimensions of Chinese Adults" is "GB / T 5703-2010 Basic Anthropometric Items for Technical Design". "GB / T 5703-2010 Basic Anthropometric Items for Technical Design" specifies that the upper arm length is measured as the vertical distance from the acromion to the lower edge of the elbow joint (hereinafter referred to as "elbow joint") at the horizontal flexion point of the forearm.

[0088] See Figure 4 For a typical human anatomy, the starting positions of the anterior superior iliac spine height and thigh length, two static human body dimensions, generally match the location of the fifth lumbar vertebra (L5). However, the ending position of the upper arm length (i.e., at the elbow joint) differs significantly from the starting position of the first lumbar vertebra (L1) (i.e., the thoracolumbar dividing line). Specifically, the elbow joint is clearly lower than the thoracolumbar dividing line. Therefore, the distance A from the elbow joint to the ending position of the fifth lumbar vertebra (L5) is not the actual length of the five lumbar vertebrae; the actual length of the five lumbar vertebrae is slightly larger than A.

[0089] from Figure 4 It can be seen that the position of the elbow joint corresponds to the position of the second lumbar vertebra L2. That is, the elbow joint is located between the starting position and the ending position of the second lumbar vertebra L2. Therefore, the number of lumbar vertebrae n included from the elbow joint to the ending position of the fifth lumbar vertebra L5 is 3 (third lumbar vertebra L3 to fifth lumbar vertebra L5) to 4 (second lumbar vertebra L2 to fifth lumbar vertebra L5).

[0090] Therefore, the distance A from the elbow joint to the termination position of the fifth lumbar vertebra L5 is the length of the 3rd to 4th lumbar vertebrae.

[0091] S104: Determine the lumbar length of the five lumbar vertebrae based on the distance dimension A and the number of lumbar vertebrae n.

[0092] Generally, the lengths of the lumbar vertebrae are not significantly different.

[0093] If the distance A from the elbow joint to the termination position of the fifth lumbar vertebra L5 is 3 segments, then the length of a single lumbar vertebra is A / 3. In this case, the actual length of the five lumbar vertebrae is 5A / 3.

[0094] If the distance A from the elbow joint to the termination position of the fifth lumbar vertebra L5 is 4 segments, then the length of a single lumbar vertebra is A / 4. In this case, the actual length of the five lumbar vertebrae is 5A / 4.

[0095] If half of the people have a distance A of 3 vertebrae from their elbow joint to the L5 vertebra, and the other half have a distance A of 4 vertebrae, then the average of the two distances can be used as a reference for subsequent design.

[0096] Waist length = (5 / 3 + 5 / 4)·A / 2 = 35A / 24.

[0097] In summary, the method for determining the human waist length provided in this embodiment first determines the distance dimension A corresponding to the length of n lumbar vertebrae based on existing static human body dimensions, and then determines the waist length of the five lumbar vertebrae based on the distance dimension A and the number of lumbar vertebrae n. This allows for the calculation of waist length dimensions not explicitly stated in existing technologies, providing a reference for mattress zoning design and thereby improving the comfort of sleep support.

[0098] Example 2

[0099] This embodiment provides a mattress partitioning method, which is applicable to application scenarios where the size of each support partition is limited according to the waist length dimensions provided in Embodiment 1. This method can improve the scientificity and rationality of partition size design and further enhance the comfort of sleep support.

[0100] See Figure 5 The mattress partitioning method provided in this embodiment includes the following steps:

[0101] S201: Obtain the waist length dimension according to any of the human waist length determination methods described in Example 1;

[0102] The specific method for obtaining the waist length has been described in Example 1. Based on Example 1, features not explained in this example will be explained using the method described in Example 1, and will not be repeated here.

[0103] S202: Determine the width of each support section based on the waist length dimension;

[0104] In this embodiment, the two documents, "Anthropometric Dimensions of Chinese Minors" and "Anthropometric Dimensions of Chinese Adults," provide different static anthropometric dimensions. Therefore, when designing mattress zones:

[0105] ①See Figure 6 The mattress designed based on the static human body dimensions provided in "Chinese Minors' Human Body Dimensions" is a zoned mattress suitable for minors.

[0106] ②See also Figure 7 The mattress designed based on the static human body dimensions provided in "Chinese Adult Anthropometric Dimensions" is a zoned mattress suitable for adults.

[0107] Furthermore, most zoned mattresses currently on the market have a three-zone or five-zone structure.

[0108] Specifically, when it is a three-zone structure, each of the support zones includes a head, shoulder and back zone (zone one), a waist and hip zone (zone two), and a leg zone (zone three).

[0109] When it is a five-zone structure, each of the support zones includes the head and neck zone (zone 1), the shoulder and back zone (zone 2), the waist zone (zone 3), the hip zone (zone 4), and the leg zone (zone 5).

[0110] Therefore, based on the target population and the number of zones as the dividing criteria, the mattress zoning method in this embodiment can be further refined as follows:

[0111] A. A three-zone mattress zoning method suitable for minors;

[0112] B. Five-zone mattress zoning method suitable for minors;

[0113] C. Three-zone mattress zoning method suitable for adults;

[0114] D. Five-zone mattress zoning method suitable for adults.

[0115] A: Three-zone mattress zoning method suitable for minors

[0116] At this point, in step S202:

[0117] The width of the head, shoulder, and back section = height - height of the anterior superior iliac spine - waist length;

[0118] The width of the lumbar and hip area = lumbar length + (anterior superior iliac spine height - perineal height) + transition dimension;

[0119] Leg section width = perineal height - transition dimension;

[0120] The transition dimension is 5cm to 10cm.

[0121] B: Five-zone mattress zoning method suitable for minors

[0122] At this point, in step S202:

[0123] The width of the head and neck section = height - shoulder height;

[0124] The width of the shoulder and back section = shoulder height - height of the anterior superior iliac spine - waist length;

[0125] The width of the waist section equals the length of the waist.

[0126] The width of the buttock section = height of the anterior superior iliac spine - height of the perineum + transition dimension;

[0127] Leg section width = perineal height - transition dimension;

[0128] The transition dimension is 5cm to 10cm.

[0129] C: Three-zone mattress zoning method suitable for adults

[0130] At this point, in step S202:

[0131] The width of the head, shoulder and back section = height - waist length - (thigh length + tibia height);

[0132] The width of the waist and hip area = waist length + (thigh length + tibia point height - perineum height) + transition dimension;

[0133] Leg section width = perineal height - transition dimension;

[0134] The transition dimension is 5cm to 10cm.

[0135] D: Five-zone mattress zoning method suitable for adults

[0136] At this point, in step S202:

[0137] The width of the head and neck section = height - shoulder height;

[0138] The width of the shoulder and back section = shoulder height - (thigh length + tibialis point height) - waist length;

[0139] The width of the waist section equals the length of the waist.

[0140] The width of the hip section = (thigh length + tibialis point height) - perineal height + transition dimension;

[0141] Leg section width = perineal height - transition dimension;

[0142] The transition dimension is 5cm to 10cm.

[0143] It should be noted that the "Anthropometric Dimensions of Chinese Minors" and "Anthropometric Dimensions of Chinese Adults" referenced the national standard document "GB / T 5703-2010 Basic Items for Anthropometric Measurement for Technical Design" when conducting anthropometric measurements.

[0144] GB / T 5703-2010, "Basic Items of Anthropometric Measurement for Technical Design," specifies that the perineal height is measured as the vertical distance from the ground to the area below the pubic symphysis. Since the lower edge of the buttocks (the natural fold where the lower edge of the gluteus maximus meets the posterior thigh) and the area below the pubic symphysis are not on the same horizontal line, the lower edge of the buttocks is lower vertically than the area below the pubic symphysis. Therefore, the height of the lower edge of the buttocks is smaller than the perineal height. Consequently, the perineal height is not equal to the leg length. Furthermore, considering the transitional position of the buttocks, the leg length is calculated by subtracting 5-10 cm from the perineal height (referred to as the "transitional dimension" in this application). Correspondingly, the hip length is calculated by adding 5-10 cm to the formula: height of the anterior superior iliac spine - perineal height (for adults: thigh length + tibialis point height - perineal height). Therefore, the formula for calculating the leg length is: perineal height - transitional dimension.

[0145] S203: Based on the width of the pillow, perform size compensation on the support area corresponding to the head and / or the leg area to determine the final width dimensions of the support area corresponding to the head and / or the leg area.

[0146] In the mattress zoning methods A through D described above, the sum of the widths of each support zone (generally less than 180cm) is usually smaller than the actual length of the mattress net. For example, with a 180×200cm mattress and 1cm wide side rails, if there is an edge reinforcement system (8cm wide) around the perimeter, the mattress net dimensions (width × length) are 162×182cm; if there is no edge reinforcement system (8cm wide), the mattress net dimensions (width × length) are 177×197cm. That is, whether it's 182cm with edge reinforcement or 197cm without, the total length will be greater than 180cm. Excess dimensions = Total mattress net length - Sum of the widths of each support zone.

[0147] The excess dimensions can be handled as follows:

[0148] When the width of the support area for the head (i.e., the head, shoulder, and back section or the head and neck section) is smaller than the width of the pillow (the pillow's width is typically 40×60cm or 48×74cm), at least some of the excess space should be allocated to the head support area to ensure the pillow can be placed properly. This ensures the waist, hips, shoulders, and back are correctly aligned with the shoulder or waist position. After ensuring the head support area can accommodate the pillow, the remaining excess space should be allocated to the leg section.

[0149] It should be noted that for mattresses with edge reinforcement systems, when considering whether a pillow can be placed in the head support area, the width of the edge reinforcement system should also be taken into account, i.e.:

[0150] If (width of the support area where the head is located + width of the edge reinforcement system) < width of the pillow, it can be considered that the size of the support area where the head is located is insufficient to fit the pillow, and the excess size should be used to compensate for the support area where the head is located.

[0151] Conversely, if (the width of the support area where the head is located + the width of the edge reinforcement system) > the width of the pillow, then the size of the support area where the head is located can be considered sufficient to fit the pillow, and the excess size can be compensated for in the leg area.

[0152] S204: Calculate the number of rows of independent pocket springs corresponding to each support section based on the waist diameter of the independent pocket springs and the width dimensions of each support section after compensation.

[0153] After obtaining the final width dimension of each support section, the number of rows of independent pocket springs corresponding to each support section can be obtained by dividing the width dimension of each support section by the waist diameter of the independent pocket spring.

[0154] For three-zone mattresses, the firmness of the waist and hips is higher than that of the head, shoulders, back, and legs; for five-zone mattresses, the firmness of the head, neck, waist, and legs is higher than that of the shoulders, back, and hips.

[0155] The following examples illustrate this with specific parameters:

[0156] There is a children's mattress targeting children aged 7-12, and the goal is to design a five-zone independent pocket spring mattress suitable for this age group. First, based on the anthropometric data in GB / T 26158-2010 "Anthropometric Dimensions of Chinese Minors," there are anthropometric data for children aged 7-10 and 11-12, with the average dimensions (50th percentile, P50) used as the base data. For children aged 7-10: height 132cm, shoulder height 103.8cm, anterior superior iliac spine height 70.4cm, perineum height 56.5cm, upper arm length 24cm; for children aged 11-12: height 146.6cm, shoulder height 116.9cm, anterior superior iliac spine height 80.1cm, perineum height 64.7cm, upper arm length 27.1cm. According to the formula, the value of A is calculated first: for children aged 7-10: A = 9.4cm; for children aged 11-12: A = 9.7cm. Then calculate the waist length: for children aged 7-10: waist length = 13.71cm; for children aged 11-12: waist length = 14.15cm. Finally, calculate the dimensions for the five zones based on the existing data: for children aged 7-10: head and neck = 28.2cm, shoulders and back = 19.7cm, waist = 13.7cm, hips = 18.9cm, legs = 51.5cm; for children aged 11-12: head and neck = 29.7cm, shoulders and back = 22.7cm, waist = 14.1cm, hips = 20.4cm, legs = 59.7cm. Therefore, for children aged 7-12, there are two methods for using a five-zone independent pocket spring mattress. First, if the weights for the two age groups are evenly distributed, then the head and neck = 29cm, shoulders and back = 21cm, waist = 14cm, hips = 20cm, and legs = 56cm. Second, if, based on actual sales data, a higher proportion of the products sold to minors aged 11-12 are found within the target group of 7-12 years old, then the 11-12 year old group can be given a higher weight, and the final values ​​will change accordingly.

[0157] This explanation uses a weighted average approach. After obtaining the data from the five zones, the sum of the data from the five zones is 140cm. The standard length of the mattress is 200cm, the reinforcement system around the four edges is 8cm wide, and the side strips are 1cm thick. Therefore, for a 200cm long mattress, the actual length of the mattress net is only 182cm. The remaining 42cm, whether it should be placed at the head or foot area, can be considered as follows:

[0158] Since most pillows for minors are 40 x 60 cm, it's essential to ensure that Zone 1 of the mattress net can accommodate the width of one pillow, allowing Zone 2 to correctly align with the shoulders and back. Currently, the head and neck area is 29 cm, with 8 cm for edge reinforcement and 1 cm for the side strips, totaling 38 cm. Considering that the pillow edge doesn't perfectly align with the mattress edge, a margin of approximately 2-3 cm is left. Therefore, 5 cm of this 42 cm is allocated to Zone 1, and the remaining 37 cm to Zone 5. The final five-zone dimensions are: Head and Neck = 34 cm, Shoulders and Back = 21 cm, Waist = 14 cm, Hips = 23 cm, Legs = 90 cm. For a 182 cm long mattress net, if the spring waist diameter is 6.5 cm, there are 29 rows of individual pocket springs. Note that due to slight compression between the springs, a spring with a waist diameter of 6.5 cm will actually be used in approximately 6.3 cm of the mattress net. Therefore, the final number of rows for the five zones is as follows: head and neck (zone 1) 5 rows, shoulders and back (zone 2) 4 rows, waist (zone 3) 2 rows, hips (zone 4) 4 rows, and legs (14 rows).

[0159] In summary, the mattress zoning method provided in this embodiment has the following beneficial effects:

[0160] ① By first determining the waist length and then determining the width of each support zone based on the waist length, the waist length is used as a key parameter in the design of the zoned mattress. This changes the existing design method of determining the waist zone length last, making the width of the waist zone more consistent with the actual waist length and the design of the zoned mattress more scientific and reasonable, especially improving the support comfort of the waist.

[0161] ② Based on the static body dimensions of different groups, we offer three-zone and five-zone mattresses suitable for minors and adults, making mattress design more targeted and positioning more precise;

[0162] ③ Considering the impact of pillow width on the head support area, a method for size compensation of the head and leg areas is proposed to ensure that the pillow can be placed normally and that the waist and hips are correctly aligned with the waist position.

[0163] ④ A method for calculating the number of spring rows based on the waist diameter of the individual pocket springs and the width of each support zone was proposed, providing a reference for the specific production of mattresses;

[0164] ⑤ The zoning data is based on the national standard for Chinese human body size big data. The data source is authoritative and reliable. The bed grid zoning data calculated based on this data is more suitable for Chinese body types and is conducive to the development of a zoned mattress that is truly suitable for Chinese body size.

[0165] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
