衍生式設計產品的造型偏好與感性評估──以眼鏡設計為例

Generative Product Design by Form Preferences with Kansei Evaluations - A Case Study of Eyeglasses Design

衍生式設計輔助系統出現後，設計過程得以明朗化。若能打破輔助系統與消費者之間的操作門檻，將可拉近消費者與心目中理想產品的距離。消費者不再需要從市面上既有的產品中挑選出自己相對喜愛的項目，而能自行建立符合自己偏好的產品外型。本研究以「黑框眼鏡」為例，探討如何打破衍生式設計輔助系統的操作門檻，期望能由「感性」做為造型調整的向度，依照各項感性程度的高低調整整體造型，幫助消費者更快速、簡易且直覺性的取得喜愛的眼鏡造型。研究統整相關眼鏡造型，經由網路問卷遴選出適合描述黑框眼鏡的9組形容詞。再配合市面上的眼鏡樣本，進行第二次的問卷調查，釐清關於黑框眼鏡的三項主要造型因子，分別為「年輕」、「樸素」與「輕巧」。再進一步分析眼鏡造型，以數量化I類方法了解造型細部因子對於各形容詞的影響力。最後以數量化I類所得之數值做為影響造型的常數，建立出衍生式設計的眼鏡模型，並產生符合各形容詞高低程度的眼鏡造型樣本。

The appearance of generative design system has succeeded in making designing progress moreexplicitly. Supporting that the operational barrier between the system and the consumers couldmake a breakthrough, thus it would be easier for the consumers to approach their ideal products. Inother words, choosing an ideal product among pre-existing items is no longer the only option forconsumers, whereas they can build up an appearance standard that fits their preferences, or theiremotions. Thus, this paper aims to take the “Plastic Eyeglass Frames” as an example for discussingmethods to break the barriers of the generative design system. Under the criteria of using the senseof perception to approach the purpose for adjusting various modeling, and we assume that by taking“perception” as a standard, it can support the consumers to understand their favorite modelingin a rapid, easy, and instinctive way. After integrating the related eyeglass modeling via internetquestionnaires, we select 12 types of plastic eyeglass frame. Moreover, we utilize questionnairesurvey again by going with the eyeglass samples on the market. Therefore, in the section of factoranalysis, we can divide the factors into three main popular descriptions, which are “Youngness”,“Plainness”, and “Lightness”. After taking further analysis of eyeglass modeling by adopting themethod “Quantification Theory Type I” to understand the impact of each description that causedby detail factors. In the end of this paper, we show the result of taking the numerical outcome fromQuantifi cation Theory Type I to control some variables in building up the eyeglass designing models,as well as various levels of eyeglass samples that fi ts descriptions from the consumers
