QFD（质量功能部署）已经被用来反映产品中客户的需求，而TRIZ（俄语首字母缩写为创造性问题解决理论）的发展是为了帮助工程师在产品开发过程中找到技术问题的创新解决方案。然而，目前还没有一种方法能有效地将QFD与TRIZ结合起来。本报告描述了一种名为创新产品开发过程（IPDP）的新方法，该方法系统地将QFD与TRIZ集成在一起，从而能够有效和系统地创建新产品的技术创新。在IPDP中，将目标产品的功能和机制并行部署到层次结构中，并通过计算机制权重，从客户需求分析中指定最需要技术创新的机制。然后，通过考虑指定机制与相应功能或质量特征之间的关系，定义待解决的技术问题，并应用TRIZ进行技术创新。通过对某洗衣机的技术改造，验证了IPDP方法的有效性。
QFD (Quality Function Deployment) has been used to reflect the needs of customers in products, while TRIZ (a Russian acronym for Theory of Inventive Problem Solving) was developed to assist engineers in finding innovative solutions to technical problems in product development processes. However, no method has been proposed to integrate QFD with TRIZ effectively. This report describes a new method, named the Innovative Product Development Process (IPDP), which systematically integrates QFD with TRIZ and enables the effective and systematic creation of technical innovation for new products. In IPDP, the target products' functions and mechanisms are deployed in parallel into hierarchical structures, and the mechanism that most requires technical innovation is specified from an analysis of customers' needs by calculating a mechanism weight. Then, the technical problems to be solved are defined by considering the relationship between the specified mechanism and corresponding functions or quality characteristics, and technical innovation is executed by applying TRIZ. The effectiveness of IPDP was confirmed by applying it to the technical innovation of a washing machine.
