目的 针对运动障碍患者用智能轮椅设备，得到高质量、易于管理的功能需求，以指导方案设计。方法 运用一种基于用户故事-需求质量评估(US-RQA)的需求获取与需求质量评估方法，首先从现有用户和现有产品出发，分别得到用户需求集和产品功能配置表，之后通过对需求集的质量进行定义，并对所得到的用户需求集在完整性、一致性和准确性方面进行评估，最后根据评估结果对需求集进行召回和修改，得到最终用户需求集。结果 结合功能配置表与最终用户需求集，得出了面向MI患者智能轮椅的功能规格总表，在此指导下进行了面向MI患者使用的智能轮椅设计，并借助三维建模软件和AIGC技术对设计方案进行了仿真表达。结论 将产品需求分析中的用户需求路线和产品功能需求路线相融合，弥补了通过单一途径获取需求的片面性与局限性，并结合基于US-RQA的需求质量评估方法，构建了一种创新的产品功能需求分析模型，有助于指导面向运动障碍患者的智能轮椅设计，为面向特定人群的产品设计提供了设计思路参考。

The work aims to design the intelligent wheelchair equipment for patients with motor impairment to realize high-quality and easy-to-manage functional requirements, thus guiding the concept design. A method of requirement acquisition and requirement quality assessment based on user story-requirement quality assessment (US-RQA) was used. Firstly, the user requirement set and product function configuration table were obtained from existing users and existing products respectively. Then, the quality of the requirement set was defined, and the integrity, consistency and accuracy of the obtained user requirement set were evaluated. Finally, according to the evaluation results, the final user requirement set was obtained by recalling and modifying the requirement set. By combining the function configuration table and the end-user requirement set, the functional specification table of intelligent wheelchair for MI patients was obtained. Under the guidance of this, the design of intelligent wheelchair for MI patients was carried out, and the design scheme was simulated with the help of 3D modeling software and AIGC technology. The integration of user requirement route and product function requirement route in product requirement analysis makes up for the one-sidedness and limitation of obtaining requirements through a single way, and combined with the requirement quality assessment method based on US-RQA, an innovative product function requirement analysis model is constructed, which is helpful to guide the design of intelligent wheelchairs for patients with motor impairment and provides a reference for design ideas of product design for specific groups of people.
