摘要
概念设计是整个产品开发周期中最重要的环节之一，它将决定产品的基本特征和主要框架。但由于在概念设计阶段主要的工作表现为对功能进行表示、维护和推理，而设计对象的几何信息却是不完全的，因此以几何信息为核心的传统ＣＡＤ系统对概念设计过程不能进行有效支持。针对这个问题，本文研究了ＣＡＤ系统支持概念设计过程的一些关键技术，包括功能建模和推理技术，以及计算机支持的概念设计过程和后续设计过程的集成技术。
Conceptual design is the most improtant process of the product development life cycle process. During the conceptual design, the designer will decide the main parts of the product. The process of the conceptual design is the work on thd functions, such as the representation, manipulation and reasoning, but the geometrical information is always absent, so the traditional CAD system which has the kernel of geometrical information modeling cannot support the conceptual design efficiently. This paper researches on the key technique of computer aided conceptual design including the function modeling, functional reasonign, and the integration of the conceptual design and other design process.
