Abstract: Aiming at the problems about current researches on integration of TRIZ and DFSS stayed at using TRIZ to solve conflicts in DFSS processes and key problems might not be identified in engineering problem solving processes， TRIZ and DFSS integration was needed to solve practical problems. The necessity and feasibility of TRIZ and DFSS integration were discussed. DMADV（define, measure, analyze, design, verity） process of DFSS was selected to conduct TRIZ tools integration， a framework was built and the core key techniques were expounded. The TRIZ and DFSS integration was focused in problem definition phases， integration routes and implementation steps were proposed， and the diesel fuel oil supply system design example was used to verify the method. The research formed a complete and executable integrating innovation method of TRIZ and DFSS， which might solve practical engineering problems for enterprises and provide guidances to realize multi-method integrating innovation.

Key words: TRIZ, design for six sigma（DFSS）, problem identification, integrating innovation

摘要： 针对目前TRIZ和六西格玛设计（DFSS）融合研究多停留在用TRIZ解决DFSS过程中存在的冲突，以及工程问题求解过程中关键问题无法识别的问题，急需将TRIZ与DFSS深入融合以解决工程实际问题。论证了TRIZ与DFSS融合的必要性和可行性；选取了DFSS的DMADV流程进行TRIZ工具的集成，构建了融合框架并阐述了其中核心关键技术；问题定义阶段是TRIZ和DFSS的重点融合阶段，提出了融合路线和实施步骤，并用柴油车辆供油系统设计实例加以验证。研究形成了一套完整可实施的TRIZ与DFSS融合创新方法，可为企业解决实际工程问题，为实现多方法融合创新应用提供新路径。
