The purpose of this study is to enable policymakers to make right and proper design principles. At the same time, the designers can take advantage of it. They may design the products that respond to the needs of the market according to the study. It is difficult for consumers to choose a pair of sport sunglasses that are suitable for them because there are few related products available on the domestic market. Being a modern developing and small-scale market, Taiwan lacks data in this field. So I needed to find out the relationship between the product types and the material layouts in different times through the information of the foreign market's competitive brands, applying them to the procedures of methodology and setting up the basic model of different types. Then questionnaires about the layout of the materials in many parts of the sunglasses are made of Taguchi Methods to see the differences among various matches. After this experiment, I conclude that there are 3 types: professional, leisure and outstanding sports sunglasses. Men differ greatly from women in the professional one. Men enjoying outdoor activities like the sunglasses made of several kinds of materials on the bridge; however women only pay attention to the material in the rear part of the temple and show the interest in no more than two elements layout. Furthermore, I find out the design rules of the popular sport sunglasses through the analysis of the parameters of the former three types by Grey Relational Method. These rules are invaluable references both for designers and decision makers.
