公理化设计理论与TRIZ集成的设计方法研究

Research on design method of integrating axiomatic design and TRIZ

公理化设计理论与TR IZ在产品设计开发中都有其优势及局限性.公理设计在系统性地生成概念初始方案方面有优势,TR IZ在解决设计中出现的冲突方面有优势.提出了集成公理化设计理论与TR IZ解决设计问题的一种方法.首先应用公理设计理论形成设计的概念初始方案;其次分析所得设计方案中可能存在的冲突,并分清冲突的类型是物理冲突还是技术冲突;然后对不同的冲突采用相应的冲突解决原理来解决;最后重新设计新的设计参数来消除冲突.通过液压修井机设计实例说明了这种方法的有效性.

Both axiomatic design and TRIZ have their advantages and disadvantages in product design. Axiomatic design has advantage in systematically generating conceptual design, while TRIZ has advantage in solving design contradiction. Therefore, a method integrating axiomatic design and TRIZ is proposed. Firstly, axiomatic design is utilized to generate conceptual design. Then the potential contradiction in the design is examined as well as identifying whether the contradiction is a physical one or a technical one. Furthermore, proper contradiction solving laws are adopted according to different contradiction types. Finally contradiction is eliminated by redesigning des feasibil gn parameters. The case study of hydraulic workover rig was given to demonstrate the ty of this proposed method.
