中文摘要：

产品创新设计的过程就是确定新的原理方案解的过程。科学效应是实现原理方案创新的有效途径。从设计流程的角度，阐明了科学效应与原理方案创新及结构方案创新的关系，并在此基础上建立了基于科学效应的产品设计流程。为了有效的实现计算机辅助创新设计过程，作者构建了科学效应库的原型系统。

英文摘要：

Confirmation of the principle solution is the esseutial process of product innovation design Scientific effects are the powerful tool for ascertaining principle innovation solution, From the view-point of design flow, the relationships of scientific effects and innovation solution of principle and structure are discussed. A prototype system of scientific effects is built to implement the process of computer aided innovation.
