本研究旨在建立一套應用於健身用收納架開發之整合性設計流程，透過多鑽石設計流程架構，結合生成式人工智慧輔助設計技術、搖籃到搖籃永續設計理念與企業識別系統設計策略，提出一套兼顧創新性、環境永續性與品牌商業價值的工業設計流程模型。多鑽石設計流程由 Hsiao 與 Tsai 於 2024 年提出，為雙鑽石設計理論的進階發展版本，將設計歷程劃分為觀察、需求、市場研究、設計目標、概念產出、概念迭代與產品確認等七個階段，具備高度的靈活性與適用性，能有效支援工業設計中高複雜性與多重迭代的實務需求。研究過程首先透過用戶訪談蒐集潛在使用者對於健身器材收納產品的實際使用需求與語彙，建立設計要素與目標語句，進而運用目標樹理論進行設計目標的層級化拆解。接續進入概念產出階段，利用生成式人工智慧 ChatGPT 作為設計輔助工具，產出大量圖像與文字構想，藉此拓展設計思維並打破傳統概念生成之侷限(Winograd and Flores,1986)。所得設計構想經設計團隊整合後填入形態學圖表進行系統性排列組合，並利用 FSM 限量性結構法將產品拆解為底層、中層、上層與主體造型四大區塊，建立多元設計選項。針對圖表中產生的設計組合，再以 Pugh 概念選擇法進行評估與篩選，評估準則涵蓋安全性、直覺使用性、材料可行性、結構穩定性與市場競爭力等面向，並由設計團隊專家賦予加權進行綜合評分，選出具發展潛力之方案。進一步進入概念迭代階段，分別從搖籃到搖籃設計觀點評估其材料循環利用與低碳排放性，並從企業識別系統設計的視覺識別、品牌理念與行為識別層面進行整體一致性檢視，確保產品在形象傳遞與商業定位上的明確性與識別度。研究最終產出之設計方案不僅回應使用者需求與設計目標，亦成功導入 AI 技術以提高創新效率，並實踐環境永續與品牌價值整合之可能性。研究結果顯示，本研究所建立之多鑽石整合設計流程能有效協助設計師於產品開發過程中系統性整合 AI 生成工具、永續設計策略與品牌識別思維，不僅提升產品創新能量與市場辨識度，亦展現該流程於未來工業設計實務推廣上的高度應用潛力。

This study aims to establish an integrated design process for the development of fitness equipment storage racks. By adopting the Multi-Diamond Design Process framework, and integrating generative AI-assisted design technology, Cradle-to-Cradle (C2C) sustainable design principles, and Corporate Identity System (CIS) design strategies, the study proposes an industrial design process model that balances innovation, environmental sustainability, and brand commercial value. The Multi-Diamond Design Process, proposed by Hsiao and Tsai in 2024, is an advanced evolution of the Double Diamond design theory. It divides the design process into seven stages: observation, needs identification, market research, design objectives, concept generation, concept iteration, and product validation. This model offers high flexibility and adaptability, making it well-suited for addressing the complex and iterative nature of industrial design practices.
The research process begins with user interviews to collect real-world usage needs and vocabulary from potential users of fitness equipment storage products. Based on this, design elements and objective statements are constructed. The goal tree method is then used to hierarchically deconstruct the design objectives. In the concept generation stage, ChatGPT is employed as a generative AI tool to produce a wide range of image-based and textual design ideas, thereby expanding design thinking and overcoming the limitations of traditional concept generation (Winograd and Flores, 1986). The resulting design ideas are then synthesized by the design team and input into a morphological chart for systematic recombination. The FSM (Function Structure Matrix) is used to divide the product into four main modules—bottom, middle, top, and main form—establishing diverse design alternatives.
Subsequently, the design combinations generated in the chart are evaluated and filtered using the Pugh concept selection method. Evaluation criteria include safety, intuitive usability, material feasibility, structural stability, and market competitiveness. Each criterion is weighted by expert designers to derive comprehensive scores, from which the most promising concept is selected for further development. In the concept iteration stage, the selected design is evaluated from a Cradle-to-Cradle perspective in terms of material recyclability and low carbon emissions. It is also reviewed from the CIS perspective, iv including visual identity, brand philosophy, and behavioral recognition, to ensure overall coherence and alignment with brand image and market positioning.
The final design solution not only meets user needs and design goals but also successfully incorporates AI technologies to enhance innovation efficiency, while realizing the potential for integrating sustainability and brand value. The research results demonstrate that the proposed Multi-Diamond Integrated Design Process effectively supports designers in systematically incorporating AI generative tools, sustainable design strategies, and brand identity thinking throughout the product development cycle. This approach not only enhances product innovation and market recognition but also shows great potential for practical application in future industrial design projects.
