摘要
本研究是以運動眼鏡之設計開發為主題，結合逆向工程技術、田口法與模流分析，從而引申出一套新型運動鏡框快速開發的製程技術，並以模流分析結合品質管理方法，從複雜的射出成型參數中分析出重點參數與合理範圍。在考量產品的耐用性與功能性下，結合設計與塑料成形性，在模流分析與田口式的品質管理間取得優化的射出成形壓力與剪切率，相較於一般的成形條件，其射出成形的剪切率可降低約 18％、射壓值可大幅減少約 26％ 間，除了可以強化產品的使用耐用性外，亦可減輕生產耗能的問題，而在結合逆向工程的新式運動眼鏡開發設計上，則更可快速設計出符合人體工學以及流線的新式造型，研究成果可提供運動眼鏡在設計、改良與生產上，一套快速且穩定的研發參考。

Abstract
This study presents a novel process technology for the rapid development of sports glasses, which combines reverse engineering technology, Taguchi method, and mold flow analysis. The key parameters and their reasonable ranges were analyzed from complex injection molding parameters using the mold flow analysis and quality management method. Optimal injection molding pressure and shear rate were obtained by considering durability, functionality, design, and plastic formability. The results show that, compared with general molding conditions, the injection molding shear rate can be reduced by approximately 18% and the injection pressure value can be reduced by approximately 26%, leading to improved durability and reduced energy consumption during production. The application of reverse engineering technology in the development and design of new sports glasses enables the creation of ergonomic and streamlined shapes in a shorter time. The research results provide a stable reference for the design, improvement, and production of sports glasses using a fast and efficient approach.
