      摘要 目的：基于质量功能展开和TRIZ理论的集成模型，针对脑卒中患者对居家康复设备的需求，设计一款便于脑卒中患者居家康复训练使用的智能设备。 方法：通过文献研究、竞品调研和场景观察分析康复设备的现状。基于扎根理论和MEC理论，对10例脑卒中患者进行访谈，并收集29位专家对需求的评分，以综合提取用户需求。利用质量功能展开计算权重并构建质量屋，运用TRIZ理论识别并解决功能矛盾，以优化设计方案。最终完成设备设计，并通过用户评分和JACK仿真分析评估可用性。 结果：该设备是一款支持7个关节部位、10种运动方式，并结合多模式、多模态交互的智能康复设备。用户对设计方案的综合评分为8.8分（满分10分），仿真结果符合人体工学要求。 结论：本研究提出的设计方案贴合现阶段脑卒中患者对居家康复设备的需求，并验证了QFD-TRIZ集成方法在康复设备设计中的有效性，为脑卒中康复设备设计提供了有效参考。

Abstract:

      Abstract Objective： Based on an integrated model of quality function deployment （QFD） and TRIZ theory， this study aims to design an intelligent rehabilitation device tailored for home-based stroke recovery. Method： Initially, a literature review， competitive product analysis， and scenario observation were conducted to examine the current state of rehabilitation devices. Subsequently, grounded theory and means-end chain （MEC） analysis were applied to interview 10 stroke patients， while demand ratings were collected from 29 experts to extract user needs. QFD was used to calculate weightings and construct a house of quality （HOQ）， and TRIZ theory was applied to identify and resolve functional conflicts， optimizing the design solution. The final design was evaluated through user ratings and JACK simulation analysis. Result： A multifunctional， intelligent rehabilitation device was developed， supporting 7 joint areas and 10 types of motion， integrated with multi-modal and multi-mode interaction. The design received an average user rating of 8.8 out of 10， and simulation results confirmed its ergonomic feasibility. Conclusion： The proposed design aligns with the current needs of stroke patients for home rehabilitation， demonstrating the effectiveness of the QFD-TRIZ integrated approach and providing valuable insights for future rehabilitation device development.
