摘要: 针对传统的创新设计方法在解决多冲突问题时,通常只能解决某一对冲突的现状,提出一种面向核心问题的系统原因识别方法,该方法可实现对多冲突问题的求解。通过质量屋获得产品设计中的冲突关系并从中选取核心问题,采用根因分析法获得各核心问题的系统原因;建立核心问题与系统原因间的关系网络图,采用最佳最差法获得各系统原因的重要度并依次开展创新设计;通过对系统原因的求解从而实现对多组冲突问题的求解。以浮置板隔振器设计为例,验证了该方法的可行性与有效性。

Abstract:  Aiming at the facts that traditional innovative design methods might only solve one pair of conflicts when solving multi-conflict problems, a core problem-oriented system cause identification method was proposed, which might solve multi-conflict problems. The conflict relationship in product design was obtained through the house of quality and the core problems were selected. The root cause analysis method was used to obtain the system causes of each core problems, and the relationship network diagram between the core problems and the system causes was established. The best worst method was used to obtain the importance degree of each system causes and carry out innovative design in order of importance. The solution of the system causes may realize the solution of multi-conflict problems. Moreover, the design of floating plate vibration isolator is taken as an example to verify the feasibility and effectiveness of this method.

Key words: multi-contradiction, complex network , system cause, floating plate vibration isolator
