Obese child last bottom pattern design method based on medical statistical analysis

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...

AI Technical Summary

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
