Parkinson's disease, as a common neurological disorder, seriously affects the life of patients. The work aims to propose a design method of walking aid for Parkinson's patients based on QFD&TRIZ, in order to improve the ease of patients in using walking aid. The combination of QFD&TRIZ theories was used as the research method to optimize the walking aid for Parkinson's patients. Through the analysis of user characteristics and walking aid's function, the user needs were obtained, and the key needs were summarized by interview survey. QFD theory was applied to construct the functional house of quality of the walking aid for Parkinson's patients to transform the key needs of users into technical needs. Then, TRIZ theory was adopted to analyze and transform conflict issues and propose solution to the conflict of product characteristics in design layer. The optimized walking aid could enable Parkinson's patients to walk under assistance and exercise a certain degree of sports rehabilitation training without completely relying on product, thus providing patients with tremor feedback and short-term rest function, and realizing multi-dimensional transformation of product functions. Through the overall analysis and optimization design of walking aid for Parkinson's patients, the possibility of combining the QFD and TRIZ theories and applying them to the design of walking aid for Parkinson's patients is proposed.
