应用TRIZ的主动再制造绿色创新设计研究

针对主动再制造设计过程中的创新问题,提出一种应用发明问题解决理论(Theory of inventive problem solving,TRIZ)的主动再制造绿色创新设计方法。将TRIZ技术冲突解决原理和环境化质量功能配置方法相结合,建立再制造设计参数与TRIZ工程参数之间的映射关联,在再制造设计需求驱动下进行零部件再制造设计改进。分析存在的主动再制造设计冲突,建立主动再制造绿色创新设计知识关联与提取机制,给出TRIZ物理冲突解决原理与知识集成的主动再制造绿色设计冲突消解方法,并从再制造性能、生命周期能耗及成本三方面进行主动再制造绿色设计评价,同时开发相应的计算机辅助设计系统。通过设计方法与工具研发,以期提高主动再制造结构绿色设计改进的效率和成功率。最后通过变速箱输入轴系零部件的设计案例验证了该方法的可行性。

Research on Green Innovation Design Method of Active Manufacturing Using TRIZ

For the innovation issue in active remanufacturing design process, green innovation design method of active manufacturing is proposed using theory of inventive problem solving (TRIZ).TRIZ conflict resolution principal and environmental quality function deployment are combined to improve the design of parts for remanufacturing using the active remanufacturing association table of design parameters and engineering parameters. The knowledge mapping and extraction mechanism of green innovation design of active manufacturing is established analyzing the existing active remanufacturing design conflicts. The green design conflict resolution method of active remanufacturing integrating TRIZ and knowledge mapping is given and the design scheme is evaluated from aspects of remanufacturing performances, life cycle energy consumption and costs. The appropriate computer-aided design system has been developed which improves efficiency and success rate of the structural green design for active remanufacturing. Finally, the design case of transmission input shaft verified the feasibility of the method.
