摘要:针对产品概念设计阶段获取的用户需求功能,利用空间定性推理方法,在功能范畴下以基本功能集为组成单元,以包含运动、能量、控制、关联、综合5种类型基本功能集的用户需求功能矩阵表达为表现形式,建立了空间变换和运算法则及其判定准则。在变换运算过程中采用三维模型二维化表达方法,将三维空间和变换运算转换为二维平面和变换运算,使得从用户需求功能到设计需求功能的变换可以伴随用户知识空间到设计者知识空间的变换实现。在全文中,通过一个实例贯串在各个部分中来验证方法的可行性。
For the customer requirement functions (CRF) obtained during the conceptual design of a product, we use the space qualitative reasoning method to establish space transformation rules and their judgement criteria in the form of matrices of the CRF that includes the five basic function sets such as motion function, power function, control function, relational function and synthetic function. We use a 3D model to transform its 3D space into a 2D plane. Thus, the transformation from CRF to designer requirement function is realized at the same time with the transformation from customer knowledge space to designer knowledge space. We use an instance to verify the feasibility of the method.
