中文摘要:

      目的 解决现有儿童下肢康复训练仪难以适配儿童患者、功能性单一及缺乏互动的问题，使儿童下肢康复训练达到更好的训练效果。方法 提出一种基于约束理论（TOC）和发明问题解决理论（TRIZ）的儿童下肢康复训练仪改良设计方法，将TOC理论中的当前现实树和冲突解决图表与TRIZ理论中的冲突解决工具相结合，提出一种针对交互体验问题的基于TOC和TRIZ理论的改良设计方法与流程，并将其应用于儿童下肢康复训练仪的改良设计中。结论 基于TOC和TRIZ理论的儿童下肢康复训练仪改良设计能够显著提高患儿的训练效果，其改良点包括造型和交互体验两个方面。利用VR技术与故事（游戏）情节结合的方式，提高了患儿的训练兴趣和参与意愿；将患儿信息上传至云端数据库，可生成不同的故事（游戏）情节，匹配不同的训练阶段，提高了训练的针对性；智能控件降低了训练过程中对康复师的依懒性，从产品角度缓解了康复师供不应求的现状。

英文摘要:

      This study aims to solve the problems that the existing lower limb rehabilitation training machine could be hardly adapted to children, has single function and lacks interaction, so as to provide better training effect for lower limb rehabilitation training of children. An improved design method for the lower limb rehabilitation training machine for children was proposed based on the constraint theory (TOC) and the invention problem solving theory (TRIZ). Meanwhile, the current reality tree and conflict resolution chart in TOC were combined with the conflict resolution tool in TRIZ, to propose an improved design method and process based on TOC and TRIZ that were specific for interactive experience problems, which were then applied to the improved design of the lower limb rehabilitation training machine for children. The improved design of the lower limb rehabilitation raining machine for children based on TOC and TRIZ could remarkably enhance the training effect on children. Its improvement points include two aspects, namely, modeling and interactive experience. Specifically, VR technology is used in combination with story (game) plot to improve the training interest and willingness to participate of the affected children; the children information is uploaded to the cloud database to generate different story (game) plots that are matched with different training stages, which could boost the training specificity; and the intelligent control reduces the dependence of training on the rehabilitation therapist, thus relieving the current situation of insufficient rehabilitation therapist from the product perspective.
