Abstract

Upper limb rehabilitation robots are pivotal devices for assisting patients with upper limb injuries in performing rehabilitation training. Guided by the principle of user demand orientation, the work aims to integrate the demands of three core user groups, including patients, medical staff, and equipment operation and maintenance personnel, to achieve a precisely designed product that enhances the target users' experience. From the perspective of the hierarchical theory of user experience design, the user demands for upper limb rehabilitation robots were systematically sorted out through methods such as questionnaire surveys and subsequently a corresponding evaluation indicator system was constructed. Furthermore, the KANO model was employed to categorize user demands and prioritize them based on their attributes. On this basis, the Quality Function Deployment (QFD) method was introduced to translate abstract user demands into concrete design elements, enabling refined design and optimization of upper limb rehabilitation robots. In this study, a scientific and rigorous framework is established for demand analysis in upper limb rehabilitation robotics and a QFD-based technical indicator system encompassing industrial engineering, interactive emotional design, and intelligent algorithms is constructed. In addition, a robustness verification method is proposed for the product system. These contributions lay a solid foundation for transforming user demands into functional innovations and advancing upper limb rehabilitation robots from mechanical aids to intelligent partners. Additionally, the findings provide new insights and methodological references for the development of similar products.
