目的 旨在弥补可供性结构矩阵在情感内容方面上的不足，进一步明确可供性结构矩阵在产品创新设计中的使用过程。方法 用更为客观的熵权法代替可供性结构矩阵原有的赋权方式，从而实现情感因素的引入，同时结合鱼骨图和冲突矩阵进行问题的分析求解，并以扫地机器人的产品创新进行方法论证。结果 把已有的可供性结构矩阵工具作为一个主导工具，提出了将情感-熵值法将情感因素融入可供性结构矩阵中，形成了完整的产品创新设计流程。结论 对扫地机器人的改进设计证明了该方法的实用性和有效性，丰富完善了可供性结构矩阵方法体系，对之后的产品设计实践提供了参考。

The work aims to make up for the deficiency of affordance structure matrix in emotional contents, to further clarify the use process of the affordance structure matrix in product innovation design. The original weighting method of affordance structure matrix was replaced by a more objective entropy weight method, so as to introduce the emotional factors. At the same time, combined with fishbone diagram and conflict matrix, the problem was analyzed and solved, and the innovation of sweeping robot was used to make a method argument. With the existing affordance structure matrix as a dominant tool, the emotion-entropy method was proposed to integrate emotional factors into the affordance structure matrix, forming a complete product innovation design process. The improved design of sweeping robot proves the practicability and effectiveness of the method, enriches and completes the affordance structure matrix method system, and provides reference for the subsequent product design practice.
