为了探究模糊前端阶段创新设想产生的机理,建立了设计活动主体与计算机辅助创新环境共同作用的认知过程模型,分析了选择性注意在创新设想产生过程中的重要作用。创新设想的产生是工作记忆处理注意焦点信息的结果。在应用机械设计理论与计算机辅助创新软件的过程中,注意焦点的形成与目标指向选择、刺激驱动捕获过程相关。匹配、回忆、变更是智能体对注意焦点的3种基本操作。利用计算机辅助创新软件InnovationTools,对立轴式冲击破碎机转子加速不理想的问题进行了分析并获得问题的特殊解,对创新设想产生过程进行了演示。
In order to explore the mechanism of the creative vision in the fuzzy front-end stage, a cognitive process model of the interaction between the subject of design activity and the computer-assisted innovation environment was established, and the important role of selective attention in the creation of innovative ideas was analyzed. The creation of innovative ideas is the result of working memory processing attention focus information. In the application of mechanical design theory and computer-aided innovation software, attention focus formation is related to target-oriented selection and stimulation-driven capture process. Matching, memory, change is the agent of the three kinds of basic operations to pay attention to the focus. The use of computer-aided innovation software InnovationTools, the vertical axis of the impact crusher rotor acceleration is not ideal to analyze the problem and get a special solution to the demonstration of innovative ideas generated.
