Based On Design Methed Of The Man-Machine Relationship

Industrial design is a subject combining rational and emotional thinking; the emotional side is reflected more in imagination and study on forms, while the rational side is reflected in the structure and function of science. Ergonomics is a systematic subject, which studies interrelationship of human, machine and environment. It guides the designer to create a system with scientific and reasonable man-machine-environment relationship. "Human criterion","machine's function" and "environmental factors" are the main research contents of ergonomics. With people-oriented thinking, how products can better serve people in the environment becomes the key ideological basis of ergonomics studies.This research summarizes the principles, procedures and methods of designing products for old people by studying the whole man-machine system of shopping cart for old people. First, it analyses the old people's physical, mental characteristics, including the data analysis of Chinese old people's body, the old people's physiological recession performance, the old people's psychological change and influence factors. In the end, it presents the principles and opinions in designing products for old people which corresponds to the old people's physiological and psychological changes.Next, it analyses the products. It researches shopping cart's market status, functional structures, colour form, processing technology and development trends etc by the methods of comparison and drawing Schema so as to find the deficiencies of this shopping cart.Then, it makes simple analysis of the environmental factors which greatly influences the old people and shopping cart. The factors includes the family domestic space, supermarket, market, shops, etc. Product design should be integrated into the environment. the paper puts forward the suggestions for the improvement of shopping environment for care of the old.And then, it summarizes the analysis of man-machine system. It is the key contents of thesis. It firstly analyses the shopping behavior of old people. Secondly it respectively analyses the relationship between the old and the shopping cart, the old and the environment, the shopping cart and environment. During the analysis it presnts the shopping cart's shape, texture, structure, etc have great impact of human using comfort so that man machine engineering get theoretical application and development on this particular shopping cart product. Finally, through this analysis author summarizes that product design should meet ergonomic requirements and proposes the design guidelines and reference methodsAt last, it proves the theory principles and process of designing products for old people by the proof of shopping cart.
