将合适的原理解综合在一起形成设计解是概念设计中的一种通用方法。现代机电一体化产品的概念设计往往是多学科的，要综合多学科的原理方案是非常费时费力的。利用原理解的功能性知识和结构性知识，提出了一种集成原理解综合方法，该方法不仅实现了多学科原理解的自动综合，而且解决了待综合原理解之间的物理冲突问题。在集成原理解综合中，设计了一个综合智能体，将原理解的功能流程链接起来形成组合原理解集，综合智能体选择可用度最高的组合原理解作为推荐的组合原理解。然后利用可拓学理论，通过对冲突功能结构的扩展和变换，处理组合原理推荐解中隐藏的部分设计冲突。以紧急切断装置设计为例，验证了集成原理解综合方法的工业实用性，表明与传统综合方法相比，综合原理解综合不仅可以得到紧急切断装置的多学科设计结果，而且可以进一步解决设计冲突（即振动冲击），优化紧急切断装置的功能结构。
Synthesizing suitable principle solutions together to form the design solution is a universal method in conceptual design. For the modern mechatronic product, the conceptual design is often multi-disciplinary, which would be extremely time consuming and labour-intensive for designers to synthesize multi-disciplinary principle solutions together. Taking advantage of functional knowledge and structural knowledge of principle solution, this article proposes an integrated principle solution synthesis method which not only achieves the automated synthesis of multi-disciplinary principle solutions but also solves the undesired physical conflicts among principle solutions to be synthesized. In integrated principle solution synthesis, a synthesis agent is developed to chain the functional flows of principle solutions to form the combinatorial principle solution set, and synthesis agent selects the combinatorial principle solution with highest availability value as the recommended combinatorial principle solution. Then extensic theory is employed to deal with the partial design conflicts hidden in recommended combinatorial principle solution by extending and transforming the conflict functional structures. A case study on the emergency cutting off device design is given to prove the industrial applicability of integrated principle solution synthesis, which indicates that compared with traditional synthesis method, integrated principle solution synthesis can not only get multi-disciplinary design result of emergency cutting off device but also further resolve the design conflict (i.e. vibration impact) to optimize the functional structure of emergency cutting off device.
