Design Of Elderly Assisted Shopping Cart Based On Human-Machine Relationship

China's elderly population ranks first in the world,the degree of aging continues to deepen,but the elderly products on the market are far from meeting their needs,the development of the aging industry is still in the initial stage,"quality" and "quantity " Can not reach a certain standard,causing widespread concern in the community.The design industry's attention is also improved to the elderly products gradually,explore the elderly related product design guidelines and excellent design cases,improve the quality of life of the elderly effectively.The elderly population have a special demand for the living environment and life aids with special physiological and psychological characteristics.Shopping as a higher frequency of life for old people,home shopping cart design related to the quality of safety and life of old people,the study of help shopping carts with old people reflect the country and society attention to old people,but also provide new direction of development for our country of the elderly shopping cart market innovation.This study is aimed at the low and middle age old people as the target group,choosing the assistant shopping cart for the elderly as the object of study,first of all,it studies the physiological and psychological characteristics of the elderly,puts forward the guiding principles for product design for the physiological function,motor function decline and psychological changes,and provides the basis for the subsequent product design of the shopping cart;Secondly,through the research on the existing shopping carts in the market,this paper makes a comparative analysis of the functions,structures,shapes,processing techniques and materials to find the potential problems and puts forward the design direction of the shopping cart;In addition,it elaborates the design principle of the assistant shopping cart under the guidance of the ergonomics theory,puts forward the corresponding design strategy,focus on the relevant man-machine size of the shopping cart,and analyzes the relevance of "human-machine-environment";Finally it uses the questionnaire survey and interview method to carry on the market research to the shopping behavior of old people,discusses the non-applicable factors and the development space of the old shopping cart emphatically,confirms the design orientation and the final plan of the shopping cart,analyzes functional structure,shape,man-machine size,material,color,finally analyzes comfort with the use of catia software to the shopping cart's handle,seat adjustment range,confirms the rationality of the program.This subject seeks to combine theory with practice,which is intended to serve as a reference and guidance for future research.
