Description
Technical Field
The invention relates to the technical field of garment design and fabric design, in particular to a shock absorption garment capable of measuring human body dimensions, and particularly relates to a sports shock absorption garment capable of measuring human body dimensions.
Background
The collection of human body surface data is an important subject of costume research, and the subject not only relates to human body type classification, and the construction of drawing patterns to obtain the size of clothes and the size of wearing clothes, but also has a very important influence on the shape difference between the clothes and the human body, namely the design of the clothes structure. Except for the clothing discipline, the anatomy, the nutrition, the human ergonomics and the anthropology, the human body surface data acquisition is very concerned. However, because the breadth of our country is broad, the climate is various, the eating habits are greatly different, and the nationalities are numerous, although the human body has a certain structural mechanism in terms of structure, the human body forms have great individual differences.
Moreover, with the improvement of life quality, the human body data of each generation of people can be changed remarkably, and the old data cannot accurately reflect the body type characteristics of the people at present. According to related data, the average height of adult men in east China is increased by 1.75cm compared with the average height of adult men ten years ago, and the adult men are higher in body size. However, GB/T1335-2008 garment No. type, which is mainly used in China, is revised on the basis of GB/T1335-1997 garment No. type, the data of the revised garment No. is almost unchanged from GB/T1335-1997 garment No. type, and the adopted human body data is obtained by measurement in the 90 th generation of 20 th century, so that the revised garment No. has very large hysteresis.
The young people are the leading force of the clothing market consumption, so that the research on the data of the young people is more, the research on the data of the old people and children is neglected, the phenomenon that the middle of the whole human body data research is heavy and the two ends of the whole human body data research are light appears in the aspect of age distribution, and the balanced development of the body type classification research is not facilitated. And for economic reasons, more people body data are collected in coastal regions at present, less people body data are collected in western regions, and the condition of region unbalance occurs.
The problems of large hysteresis, unbalanced regions and over-centralized research population are faced to the acquisition of human body data in China, and the current human body measurement experiment has great defects. The measurement methods mainly used at present are a martin measurement method, a three-dimensional human body scanning method and a stereographic method. Because the stereographic method with insufficient precision is rarely used for scientific research and is mostly used for auxiliary measurement, the three-dimensional human body scanner has extremely high cost, can not be equipped by all measurement teams and can not be popularized on a large scale, and the martin measurement method is time-consuming and labor-consuming, high in precision and low in efficiency. In addition, in the development of clothing products, particularly sports clothing, underwear and other articles, the body types of target people are often required to be measured, the measurement cost is extremely high, the time consumption is great, and the fast-paced product development requirement cannot be met. For the reasons, the invention provides the shock absorption garment capable of measuring the dimension of the human body, the shock absorption garment is high in universality, is beneficial to solving various pain points in human body measurement, and is a concept which is not involved in the current patent.
