本书提出了一种创新设计理论的综合体系，能够提升设计中所必需的创新思维和创造力。该理论构建了设计中各元素以及设计过程的模型和算法，能够帮助收集和量化概念设计阶段中可用的较为模糊的设计信息，通过推动创造性的思维和抽象性思考，促进设计的逻辑性和结构化的进程。该理论应用可拓学探索设计问题的重构和设计思维的发散，并应用公理化设计理论指导功能需求和设计参数的迭代分解，在此过程中促进创新思维和创新设计方案的产生。可拓学与公理化设计理论的协同作用，是跨专业、跨学科的协同研究和发展，同时融合了中国哲学中的抽象思维模式和西方理论中的迭代设计流程。
本书能够帮助学生以及工程、自然和社会科学、商业等多领域的从业人员建立解决设计问题的创造性和创新性的思维及方式。

李文娟，北京航空航天大学博士后，专注于机械设计方法理论的研究工作，提出了公理化设计与可拓学的融合理论，为创新设计和智能设计开辟了新的研究方向。
