Problems solved by technology

[0007] For a special group of obese children, the field of shoe last design for obese children in China is almost blank at present, and there are two major problems: (1) Studies have shown that the width of the feet of obese children is significantly wider than that of normal children. The shoe lasts of children's shoes are all designed and produced according to the proportion of normal children's feet, which will cause serious damage to the normal development of obese children's feet; (2) The foot shape survey of the Chinese population uses manual measurement methods, and the measurement errors are relatively large
This kind of ill-fitting may be barely acceptable to normal people. However, as a special group with sensitive feet, obese children will wear ill-fitting shoes for a long time, which will increase the stress on the foot-shoe interface and affect the normal development of the feet. , have an irreversible impact on their healthy growth

Embodiment 1

[0046] The specific implementation steps of the shoe last design for obese boys (taking obese boys aged 8-9 as an example):

[0047] (1) Mark the characteristic parts of the foot:

[0048] Remove the shoes and socks of the tested children, and use reflective marking points to stick on the characteristic points of the feet: the point at the end of the toe, the point at the protruding point of the big toe, the point at the protruding point of the little toe, the point at the metatarsal point of the first toe, the point at the fifth toe Plantar point, lumbar fossa point, heel process point point. The above-mentioned points are the foot feature data that must be obtained for the design of the last base sample.

[0049] (2) Obtain an accurate 3D model of the foot:

[0050] Adopt Infofoot ? The three-dimensional scanner scans the feet (bare feet) of the obese children under half-weight load, obtains the three-dimensional models of the left and right feet of the test children resp...

Embodiment 2

[0076] The specific implementation steps of the shoe last design for obese girls (taking obese girls aged 8-9 as an example):

[0077] (1) Mark the characteristic parts of the foot; (2) Obtain an accurate 3D model of the foot; (3) Analyze the characteristic data of the foot; (4) Conduct exploratory analysis on the characteristic data of the foot; (5) Analyze the difference between the left and right foot data (6) Determine the characteristic parameters of the bottom of the last of the obese girl; (7) Draw the shape of the bottom of the shoe last of the obese girl. The specific steps can be found in Example 1.

[0078] Among them, when analyzing the differences in left and right foot data, it was found that there is a significant difference in the width of the big toe between the left and right feet of obese girls (p=0.001). For the rest of the parameters, the data of the right foot (dominant foot) is selected as the benchmark.

[0079] Here, the internal width of the great t...

Abstract

The invention discloses an obese child last bottom pattern design method based on medical statistical analysis. The method comprises the following steps: (1) marking foot feature parts; (2) acquiring an accurate three-dimensional foot model; (3) analyzing foot feature data; (4) performing exploratory analysis on the foot feature data; (5) analyzing left foot and right foot data differences of a boy/girl; (6) determining last bottom part feature parameters of the boy/girl; (7) drawing an obese child last bottom pattern. One complete scheme for obese child last bottom pattern design is provided, exploratory analysis and difference analysis are performed on the foot feature data with a medical statistical method, data conversion processing is performed and applied to the last bottom pattern design, and the blank in the field of the obese child last bottom pattern design in China is filled up. The method is high in accuracy, good in reliability and high in repeatability and can be directly applied to the field of obese child last bottom pattern design in the shoemaking industry.

Description

technical field [0001] The invention belongs to the technical fields of ergonomics, shoe last design and medical statistics, and in particular relates to a method for analyzing the characteristic data of obese children's feet by using medical statistical methods and applying it to the design of shoe last samples. Background technique [0002] Domestic and foreign studies have shown that obesity is also inextricably linked to various bone and joint diseases (such as gout, bone and joint pain, etc.), all of which are related to plantar overload caused by overweight. When the human body is obese, the fat will cover the arches of the feet, especially in childhood, because the arches of the feet are not yet fully developed, and excessive arch loads are more likely to lead to flat feet (Du Xiaoning, Zhao Xiaozhe, Zhang Xin. Plantar pressure of normal feet and flat feet And gait characteristics [J]. Chinese Tissue Engineering Research and Clinical Rehabilitation, 2008,12(46):9058-9...
