概念设计作为产品开发的前端,其创新程度取决于设计过程中大量新知识的应用。为研究立式加工中心外观设计中新知识的获取问题,论述了设计知识的获取方法,特别是隐性知识的挖掘与利用。分析了设计中知识流动的过程及其与设计过程的关系,构建了概念设计过程模型并提出了设计概念。通过设计知识的获取与综合利用,设计了立式加工中心的外观,为知识密集型产品的设计提供参考。 As the front end of product development, concept design depends on how much new knowledge is used in the design process. In order to study the acquisition of new knowledge in the design of vertical machining center, the methods of obtaining design knowledge, especially the excavation and utilization of tacit knowledge, are discussed. The process of knowledge flow in design and its relationship with design process are analyzed. The conceptual design process model is constructed and the design concept is proposed. Through the acquisition and comprehensive utilization of design knowledge, the appearance of vertical machining center is designed, which provides a reference for the design of knowledge-intensive products.
