目的 为解决用户在房车使用上带来的便捷性差，使用率低等问题，设计了一款适用于旅居的共享房车，以增强共享化下的需求满足度。方法 以层次分析法(AHP)归纳用户需求，确立需求权重排序。结合质量功能展开理论(QFD)将需求因素映射到生活空间、外观、功能以及性能等设计要素的描述上，并透过自相关矩阵获取设计矛盾源。基于发明问题解决理论(TRIZ)化解了多功能家具制作和功能区分布合理、家居配置和水电的安装维护以及行车安全性和供水供能系统之间的设计矛盾。结论 依照研究结论开展设计实践。设计方案通过了可用性测试，满足了设计预期。研究流程为相关创新设计提供了参考思路。

The work aims to design a shared recreational vehicle (RV) suitable for travel to solve the users' problems of poor convenience and low usage of RVs, so as to enhance the satisfaction of needs under sharing. A hierarchical analysis (AHP) was used to summarize user needs and establish the ranking of need weights. The QFD theory was used to map need factors to design elements such as living space, appearance, functionality and performance, and the autocorrelation matrix was used to identify sources of design conflict. Based on the Theory of Inventive Problem Solving (TRIZ), the design contradictions between the production of multifunctional furniture and the rational distribution of functional areas, the installation and maintenance of household configurations and utilities, as well as the safety of traffic and water supply systems, were resolved. The design practice is carried out in accordance with the findings of the study. The design solution passes the usability test and meet the design expectations. The research process provides reference ideas for related innovative designs.
