本文發展出一可行的新設計原型之系統化創新流程，以協助研發工程師快速找到產品創新的概念。本系統化流程統合技術分析、專利迴避設計策略、發明解決問題理論與專利侵權判準規則以迴避侵權的方式開發可行的新設計原型。依此設計流程，本文以導光板為例，進行重新設計，該設計可有效地提升導光板對光源利用率，並改善原網點式導光板其出光之光亮度與均齊度表現。

To guarantee a higher efficiency in research and development as well as
substantial returns on investment, it is essential that corporations reduce the costs incurred by R&D departments. This paper proposes an integrated process of systematic innovation for redesigning prototypes. This process integrates a technology analysis, patent design-around strategies, innovative design methods in the theory of inventive problem-solving, and rules of patent infringement judgment. It is expected that a redesign of prototypes of light guide panels by design-around strategies to avoid infringement of existing patents can be used to illustrate the integrated process.
