Description
Technical Field
The invention relates to the technical field of garment design and fabric design, in particular to a shock-absorbing garment capable of measuring human dimension, and especially relates to a sports shock-absorbing garment capable of measuring human dimension.
Background
The collection of human body surface data is always an important subject of clothing study, and the subject not only relates to the classification of human body types, construction of drawing patterns, obtaining of clothing sizes and wearing sizes, but also has a very important influence on the morphological difference between clothing and human body, namely, the design of clothing structures. Except for clothing disciplines, anatomies, nutriology, ergonomics, and mankind are all very concerned with the acquisition of human body surface data. However, since the Chinese operators are wide, the climates are various, the eating habits are very different, and the people have a certain structural mechanism in terms of structure, but the human body forms have great individual differences.
Moreover, with the improvement of life quality, the human body data of each generation can be changed obviously, and old data cannot accurately reflect the body shape characteristics of the present human. According to the related data, the average height of adult men in the east China is increased by 1.75cm compared with that of adult men in the ten years ago, and the average height of adult men in the east China is higher. However, the GB/T1335-2008 clothing size used mainly in China is revised based on GB/T1335-1997 clothing size, the data of the clothing size is almost unchanged from the GB/T1335-1997 clothing size, the adopted human body data is obtained by measuring the 20 th generation 90, and the hysteresis is very large.
Since young people are the dominant force of clothing market consumption, the research on the human body data of young people is more, and the research on the human body data of old people and children is neglected, so that the phenomenon of heavy middle and light two ends appears in the aspect of age distribution in the whole human body data research, which is not beneficial to the balanced development of body type classification research. And because of economic reasons, the current collection of human body data of people in coastal areas is more, and the collection of human body data of people in western areas is less, so that the situation of unbalanced areas occurs.
Not only is the collection of human body data in China subject to the problems of large hysteresis and unbalanced territory and too concentrated research crowd, but also the current anthropometric experiment has great defects. Currently, the main measurement methods used are Martin measurement, three-dimensional body scanning and stereography. Because the stereo photography method is not accurate enough and is rarely used for scientific research and is mostly used for auxiliary measurement, the three-dimensional human body scanner is extremely high in cost, not all measurement teams can be equipped, the large-scale popularization cannot be realized, the Martin measurement method is time-consuming and labor-consuming, and the Martin measurement method is high in precision and low in efficiency. In the development of clothing products, particularly articles such as sportswear underwear, the body type of a target crowd is often required to be measured, the measurement cost is extremely high, the time consumption is huge, and the rapid-rhythm product development requirement cannot be met. For the above reasons, the present invention proposes a damping garment capable of measuring human dimensions, which has high popularity and helps to solve various pain points in human measurement, and is a concept not related in the current patent.
