基于QFD&TRIZ的帕金森患者助行器优化设计研究

目的 帕金森病作为常见神经类病症，严重影响着病患群体的生活。为提高帕金森病患者使用助行器产品的便利性，提出基于QFD&TRIZ的帕金森患者助行器优化设计方法。方法 将QFD&TRIZ理论组合作为优化帕金森助行器的研究方法。通过对用户特点和助行器功能的分析获取用户需求，并采用访谈调研总结出重点需求。运用QFD理论方法，构建出帕金森患者助行器功能质量屋，将用户的重点需求转化为技术需求；运用TRIZ理论进行冲突问题的分析与转化，并针对设计层面产品特性的矛盾提出解决方案。结果 优化帕金森患者助行器，让患者在实现助力行走的同时，可不完全依赖产品进行一定程度的运动康复训练；为患者提供震颤反馈及短期休息功能，实现产品功能多维度的转化。结论 通过对帕金森患者助行器的整体分析和优化设计，提出了将QFD&TRIZ理论融合并应用于帕金森患者助行器产品设计的可能。

Design of Walking Aid for Parkinson Patients Based on QFD&TRIZ

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.
