【摘要】：效应推理是概念设计的重要方法,推理结果是否为创新解会影响功能分解的过程和结果。为能够在推理中取得创新解,提出以拓展变换支持创新的可拓学推理方法,将效应推理过程分为流拓展变换和效应拓展变换两个阶段,流拓展变换用来构建效应链,通过效应拓展变换产生创新解。对两极效应模型及其组合模式建立了关系元表达,来支持信息元的拓展变换;给出了流的相关与匹配定义,建立了基于匹配和相关分析的流拓展变换规则,支持正向、逆向及混合推理;分析了流拓展变换结果的特点,根据效应拓展变换的目的,提出采用解释结构模型分析效应拓展变换关系,实现效应拓展变换。机器人末端夹持器设计实例验证了所提方法的正确性。
[Abstract]:Effect reasoning is an important method of conceptual design. Whether the result of reasoning is an innovative solution will affect the process and result of functional decomposition. In order to obtain the innovative solution in reasoning, an extension transformation method to support innovation is proposed. The process of effect inference is divided into two stages: flow extension transformation and effect expansion transformation, which is used to construct the effect chain and generate innovative solutions through the effect expansion transformation. The relational element representation of the bipolar effect model and its combination model is established. The definition of flow correlation and matching is given, and the rules of flow expansion transformation based on matching and correlation analysis are established to support forward, reverse and mixed reasoning. According to the purpose of the extended effect transformation, an interpretative structural model is proposed to analyze the relation of the effect expansion transformation and to realize the effect expansion transformation. The design example of the robot terminal gripper verifies the correctness of the proposed method.
