摘　　要：文章基于质量功能展开法(QFD)和发明问题的解决理论(TRIZ),结合用户工艺需求、性能需求与技术特性之间的依赖与反馈,提出一套针对工程装置的创新设计流程。基于该流程,在工程条件约束下,将加工工艺与性能需求转换为技术需求,并对技术需求重要度进行量化,实现初步设计;然后采用TRIZ方法解决负相关矩阵的矛盾冲突,进而得到最终的设计装置。采用该流程,对微射流冷却装置进行设计,其结果表明,该装置满足工程要求又符合工艺、性能需求,从而验证了该创新设计流程是可靠的。Based on the quality function deployment(QFD)and theory of inventive problem solving(TRIZ),and combining the dependence and feedback among the user's process requirements,performance requirements and technical characteristics,a set of innovative design flow for engineering devices is proposed.Through the guidance of the process,under the constraint of engineering conditions,the processing technology and performance requirements are transformed into technical requirements,and the importance of technical requirements is quantified to guide the preliminary design.Finally,the contradiction of negative correlation matrix is solved by TRIZ method,and the design is carried out in detail.A micro-jet cooling device was designed to meet the engineering requirements,process and performance requirements,and to meet the basic requirements of users.At the same time,the reliability of this innovative design process was verified.
