產品造形意象元素設計系統之研究——以行動影音產品為例

The Form Element System Design for Portable Multimedia Digital Products

產品的構想與造形設計是設計師不可缺少的必備技能，設計師往往藉由視覺的感官刺激，激發出更具創意、有價的產品，而數位化設計資訊的應用，已成為知識、經驗、構想發展的新利器。本研究的目的在於擷取行動影音產品的造形元素，結合各種感性形容詞語彙的運用，建構一個支援設計師發展產品造形階段的造形意象元素整合系統，透過本系統協助設計師發展構想，了解產品的造形意象。首先，本研究透過專家訪談，將市面上搜集到的65種行動影音產品進行造形元素拆解，並以CAD軟體進行2D造形元素描繪，再運用型態分析法與焦點團體法（Foucs Group），共篩選出整體造形元素15種、輸入造形元素15種、輸出造形元素12種，即47種造形元素。而形容詞語彙的篩選，則運用問卷調查與語意差異法（SD），從100組形容詞語彙，選出具有評價性、力量性與行動性三類共8組語彙。為了解造形元素與感性形容詞語彙的關聯性，透過平均數折線圖的方法，探討每一種造形元素與語彙之間的相關性係數。最後，依每種元素在各個形容詞語彙相關性係數與設計需求程度值之間的相差值，以Visual Basic程式語言，完成本造形元素系統的開發。此系統能在資深與新進設計師之間提供一個設計知識累積與傳承的平台，在快速掌握客戶的要求與條件之下，設計師可利用網際網路進入此系統，得到多種造形設計參考，並可將新上市產品與語彙的關連性加到資料庫中，增加造形元素的變化性與完整性。

Product form design and ideas are indispensable techniques of designers. The external stimulus often triggers designers to generate creative and valuable products. Particularly, the application of digital design information has been a new tool in the development of knowledge, experience and ideas. The objective of this study is to use different perceptual adjectives to capture the form element of the portable multimedia digital products, and to help designers establish a product form element integration system at the design development stage. Designers can rapidly use the system to integrate the appearance of products. Furthermore, in the product form development stage, designers can understand product images via this system. This study is divided into 5 stages. The first stage is the classification and choice of form elements. Through the interview with experts, the form elements of 65 types of portable audio-video products found in market were identified. The CAD software was used to perform 2D form element scanning from which 42 types of form elements could be specified, including 15 total form elements, 15 input form elements and 12 output form elements. In the second stage, 100 pairs of perceptual adjectives for portable audio-video products were collected. Through the subjective screening, 61 pairs were chosen and further divided into three types in the semantic differential method: appraisal, strength and action types. Then from the questionnaire investigation in the third stage, eight groups were chosen finally. According to the screened samples from Stages one and two, the relationships between form elements and perceptual adjectives were investigated. From the average of broken-line graph, the differences among one element and the others could be investigated from analysis of form imagery at Stage 4. At Stage 5, the degree value of each form element on each perceptual adjective can be built by using Visual Basic as the system language. From the searching and integration by the users, several concrete appearances of the products can be obtained. Moreover, the accumulation and passing on of design knowledge are shared between experienced and junior designers from the platform of element integration system. In this kind of training mode, designers can rapidly get the requirements and conditions of customers in hand, adding variety and wholeness to product form design.
