目的 研究基于动作过程的产品设计模式。方法 通过观察人们起立、坐下的过程，开展功能分析，描述腿部各支点变化的规律，构建多点支撑，形成设计参考指标，利用工业设计的方法进行产品设计。 结论 完成了草图、数字化模型、3D 打印模型的设计构建，展现设计过程，为后续研究及同类产品提供有效的指导建议。

It aims to make a research on product design mode based on the action. By observing the process of people's standing and sitting, the function analysis is carried out, the rules of the variation of each leg in the leg are described, the multi point support is constructed, the design reference index is formed, and the product design is designed by the method of industrial design. The design and construction of the sketch, digital model and 3D printing model are completed, showing the design process and providing effective guidance for subsequent research and similar products.
