基于需求—功能映射分析的概念设计

产品设计是从市场需求映射（求解）至产品（设计解）的过程。概念设计直接考虑客户需求，是产品设计过程中最重要、最复杂，同时又是最活跃、最富创造性的设计阶段。利用价值工程的思想，提出了一种需求和功能分析的方法，将用户需求转化为产品的功能系统图Function System Chart(FSC），把用户需求与产品功能有机联系起来，并利用数据库技术实现概念产品的设计过程，从而能够有效地实现客户需求向概念设计的转化。

Application of Function Analysis in Conceptual Design

Product design is a procedure that enterprises meet the needs of consumers; conceptive design is one of the steps in product design and it directly considers requirements of consumers. So how to supply consumers with satisfying function is the essential point. On the basis of function analysis of Value Engineering, the paper puts forward a new method to exercise function definition and function analysis, implements conceptual product design procedure with database techniques.A new way is gotten to convert requirements to conceptual product.
