中文摘要：

提出了能量链原理，从设计本质的层面上指出，机械产品创新设计求解的本质过程即是选择合适的能量转换原理及确定支持相应能量转换的结构方案的过程。在广义定位原理与能量链原理的基础上，建立了相应的概念设计产品信息模型，构建了支持能量转换推理的机械产品概念设计过程模型以及支持功能结构自动映射过程的概念零件编码体系。介绍了基于该原理开发的概念设计CAD软件系统——DARFAD。

英文摘要：

Energy Chain Principle was put forward and it pointed out that the essence of the conCeptual innovation design for mechanical products is the choice of proper principle for energy transforming and the corresponding structure scheme supporting the energy transforming function. Based on Generalized Location Principle and Energy Chain Principle, the corresponding conceptual product information modeling was established and the conceptual design methodology supporting energy transforming deduce was built, The coding system of conceptual parts for the function--structure automation mapping was founded. As a conceptual design tool, DARFAD（Decomposition and Reconstitution for Automation Design） is developed and introduced.
