中文摘要:

      目的 为明确电热水器产品功能要素与需求要素的对应关系，提高电热水器用户的使用满意度。方法 通过构建QFD与TRIZ的集成设计模型，使用亲和图筛选分析顾客需求，利用QFD整理顾客需求权重并构建质量屋，从而明确关键设计要素;通过TRIZ分析方法判断了质量屋中的矛盾类型后，将设计要求转换为与工程要素间的矛盾，并利用阿奇舒勒矩阵中相应的发明原理，提出了解决矛盾的方法。结果 通过模糊综合评价法筛选最优设计方案，最终的评估结果表明新的设计方案满足了实际市场用户需求的目标问题优化。结论 从用户被动发现产品零部件寿命耗尽转换为产品信息主动提示，并具备辅助用户操作的结构，提升了用户需求与产品功能的匹配度，可见质量功能展开理论与发明问题解决理论的集成设计方法对产品概念设计阶段的重要性，为之后的室内智能家电设计研究提供了参考。

英文摘要:

      The work aims to clarify the corresponding relationship between the functional elements and need elements of electric water heater products, and to improve the user satisfaction of electric water heaters.By constructing an integrated design model of QFD and TRIZ, the affinity graph was used to screen and analyze customer needs, QFD was used to sort out the weight of customer needs and construct a house of quality, to clarify the key design elements; the types of contradictions in the house of quality were judged by TRIZ analysis. Then, the design requirements were converted into contradictions with engineering elements, and a method to solve the contradiction was proposed with the corresponding invention principles in the Altshuller matrix. The optimal design scheme was screened by the fuzzy comprehensive evaluation method, and the final evaluation result showed that the new design scheme satisfied the target problem optimization of the actual market user needs. The change from user's passive discovery of product parts life exhaustion to an active prompt of product information with structure assisting user operation improves the matching degree between user needs and product functions, shows the importance of the integrated design method of quality function deployment theory and inventive problem solving theory for the conceptual design stage of products, and provides a reference for the subsequent research on the design of indoor smart home appliances.
