Description

Technical Field

[0001] The present invention belongs to the technical field of textiles, and in particular relates to a method for determining the curvature radius of a sponge pad with a zipper-like structure, a production method, a system, equipment and a medium. Background Art

[0002] A mattress is a piece of bedding that is placed between the human body and the bed to ensure that consumers get a healthy and comfortable sleep by dispersing body pressure.

[0003] Children often sleep in a supine position. When lying flat, their abdomen exerts pressure on the sunken lumbar spine, causing downward force on the lumbar spine. Sleeping on a mattress that is too soft can easily cause them to sink, making it difficult to turn over. Sleeping on a mattress that is too hard lacks effective support for the sunken lumbar spine, potentially causing the thoracic and cervical vertebrae to tilt forward, impacting spinal development. Spinal damage can affect height and aesthetics, as well as the development of internal organs. Therefore, for children, it is crucial to ensure that the mattress effectively supports the entire S-shaped curve of the spine. However, commercially available children's mattresses do not effectively support this entire S-shaped curve. Furthermore, a child's spine undergoes significant and rapid growth and change during development. For example, infants aged 3-6 require enhanced support in the lumbar and hip regions to prevent kyphosis. School-age children aged 7-10 need to evenly distribute the rapidly increasing weight load. Pre-adolescents aged 10-12 also require support to prevent scoliosis. However, existing children's mattresses can only meet the needs of a certain stage, and the needs of different stages can only be met by replacing the mattress, resulting in a waste of resources and an increase in consumer usage costs.

[0056] See also Figure 1 , Figure 1This is a flow chart of a method for determining the curvature radius of a zipper-like structure sponge pad, shown in an exemplary embodiment of the present application. The zipper-like structure sponge pad is used as the core of a mattress or sofa cushion. The zipper-like structure sponge pad includes an upper layer 11 and a lower layer 12. The difference between the preset density of the lower layer 12 and the preset density of the upper layer 11 is 2-5 kg / m 3 , that is, the preset density of the upper layer 11 is 2-5 kg / m lower than the preset density of the lower layer 12 3 The upper layer 11 is provided with a plurality of upper teeth 111, and the lower layer 12 is provided with a plurality of lower teeth 121. The lower teeth 121 mesh with the upper teeth 111. The upper teeth 111 include a base 1111 and a crown 1112 with an arc-shaped protrusion. Along the longitudinal direction, the zipper-like structure sponge pad is sequentially divided into the first zone 13 to the sixth zone 18. The first zone 13 to the second zone 14 are respectively used to provide support for the head, shoulders and neck of young children under nine years old (excluding nine years old), including children aged 6-9 but over 145 cm in height. The third zone 15 is used to provide support for the hips and legs of young children under nine years old (excluding nine years old) and people over nine years old (including nine years old). The sixth zone 18, the fifth zone 17 and the fourth zone 16 are respectively used to provide support for the head, shoulders and neck and waist of people over nine years old (including nine years old).

[0057] Please continue reading Figure 1 In an exemplary embodiment of the present application, a method for determining the curvature radius of a zipper-like structure sponge pad includes steps S110 to S130, which are described in detail as follows:

[0058] Step S110. Obtaining the preset density of the upper layer, the preset density of the lower layer, and the preset total longitudinal length of the zipper-like structure sponge pad;

[0059] It should be noted that, in this application, longitudinal length refers to the direction of human body extension, that is, the direction from head to toe;

[0060] Step S120: Solving the objective function based on the preset density of the upper layer, the preset density of the lower layer, and the preset total longitudinal length of the zipper-like sponge pad to obtain the optimal solution for the curvature radius of the lowest point of the base of the upper teeth and the optimal solution for the curvature radius of the highest point of the crown of the upper teeth in each region;

[0061] For example, the objective function is shown in formula (I):

[0062]

[0063] In formula (I), r i1 The curvature radius of the lowest point of the base of the upper tooth is in mm; r i2 is the radius of curvature of the highest point of the crown of the upper tooth, in mm; i represents the number of the area, with a minimum of 1 and a maximum of 6; Dμ The preset density of the upper layer, in kg / m 3 ;D d The preset density of the upper layer, in kg / m 3 ;D i is the overall density of the corresponding area, in kg / m 3 .

[0064] Step S130 : Determine the optimal solution as the curvature radius of the lowest point of the base of the upper teeth in the corresponding area and the curvature radius of the highest point of the crown of the upper teeth.

[0065] In the related art, children's mattresses generally use sponge pads. After analyzing the related art, the inventor found that existing children's mattresses can only meet the needs of a certain stage, and the needs of different stages can only be met by replacing the mattress, resulting in a waste of resources and an increase in consumer usage costs. Therefore, the inventor considered dividing the sponge pad into six areas along the longitudinal direction during the design of the children's mattress, and dividing the sponge pad into two upper and lower layers with different densities. Both the upper and lower layers are provided with teeth, and the curvature radius of the lowest point of the base of the upper teeth in different areas and the curvature radius of the highest point of the crown of the upper teeth are designed to be differentiated. The hardness of the sponge pad in different areas is controlled to be differentiated, so that the mattress can meet the usage needs of children of different age groups. Specifically, by obtaining the preset density of the upper layer, the preset density of the lower layer and the preset total longitudinal length of the zipper-like structure sponge pad, the objective function is solved based on the preset density of the upper layer, the preset density of the lower layer and the preset total longitudinal length of the zipper-like structure sponge pad, and the optimal solution of the curvature radius of the lowest point of the base of the upper teeth in each area and the optimal solution of the curvature radius of the highest point of the crown of the upper teeth are obtained. The optimal solution is determined as the curvature radius of the lowest point of the base of the upper teeth and the curvature radius of the highest point of the crown of the upper teeth in the corresponding area. In other words, in the process of determining the curvature radius of the lowest point of the base of the upper teeth and the curvature radius of the highest point of the crown of the upper teeth, the preset densities of the upper and lower layers are taken into account, and the objective function is solved, so that the hardness of the sponge pad in different longitudinal areas is differentiated, and different areas meet the usage needs of children at different stages of growth, thereby solving the technical problem that existing children's mattresses can only meet the needs of a certain stage, and can only meet the needs of different stages by replacing mattresses, resulting in waste of resources and increased consumer usage costs.

[0068] Step S510: Determine the longitudinal length of each area based on the preset total longitudinal length of the zipper-like structure sponge pad and the preset longitudinal length ratio of each part of the minor child;

[0069] It should be noted that, in this application, the longitudinal length ratio of each part of the minors is obtained by summarizing and arranging the longitudinal lengths of each part of the minors;

[0070] Step S520. Solve the objective function based on the preset density of the upper layer, the preset density of the lower layer, the preset total longitudinal length of the zipper-like structure sponge pad, and the longitudinal length of each area to obtain the optimal solution of the curvature radius of the lowest point of the base of the upper teeth in each area and the optimal solution of the curvature radius of the highest point of the crown of the upper teeth.
