Innovative Design Of Four Wheel Walker Based On Function Analysis And TRIZ Integration

In the aging society,the life of the elderly has increasingly become the focus of social attention.With the increase of age,the changes in the body skills of the elderly,the inconveniences of the legs,the poor balance and the weakening of the weight bearing ability constantly interfere with the life of the elderly.The four wheeled walker can solve the problems in life.It is the bridge between the old people and the surrounding environment.It is a necessary tool for the old age.However,the four rounds of the domestic market are mostly functional patchwork,lack of theoretical support and functional requirements of the user,resulting in the weak design position and the deviation between the product design and the needs of the users.Therefore,the study proposes to combine the functional needs of the elderly to study the four wheel walker.The main purpose of this study is starting with the user to eliminate the negative factors affecting the functional experience of the target users,and to construct a product design model based on the functional analysis and the theory integration of the invention problem solving,and to guide the design and practice of the next project.It provides reference for series development of Walker.In this paper,first of all,through a large number of reading and sorting out the literature,this paper deeply understands and analyzes the research status of the four wheeled walker at home and abroad,sums up the problems in the design of the four round of domestic aid,and then understands how to analyze the problems through functional analysis and how to analyze the problems through the analytical tools and solutions in TRIZ and The final solution is found,and a product innovation design model based on functional analysis and TRIZ integration is built.Next,we get information about users' real functional needs through observation,interview and questionnaire.In the end,the longitudinal and lateral analysis of the four wheeled auxiliary machine is carried out,and the innovative design of the four wheel walker is carried out by using the product innovation design model based on functional analysis and TRIZ integration.At the same time,the design scheme is evaluated and verified.
