  • 本研究致力於探索體驗設計方法和腦力寫作法在鐵鎚設計中的應用,尤其關注其如何深化設計思維過程並提升設計構想的心理效益。鑒於鐵鎚作為一種基礎工具,在物理功能和結構設計上已近乎完善,傳統的創新路徑如提高使用效能、人因工程和安全性對其而言已顯得有限。因此,本研究旨在探查如何通過設計方法的應用來提升使用者的情感體驗和心理上的滿足,從而拓展鐵鎚設計的創新空間。
    本研究分為四個階段進行:首先,在第一階段,研究生收集並分析了一系列獲獎的鐵鎚設計作品,並嘗試應用體驗設計方法產生初步設計構想。隨後,在第二階段,大學二年級學生利用腦力寫作法和體驗設計方法分別產生兩組新的構想草圖。在第三階段,對所有設計構想進行風格和表述的統一化處理,以確保構想草圖的一致性並通過問卷調查評估其創意性程度。最終階段,通過量化分析探討不同設計方法對於設計構想的創意性、新穎性和多樣性的評分。
    通過以上研究,本文期望為設計學界提供一個新的視角,即在傳統手工工具設計中,尤其是鐵鎚的設計上,如何運用設計方法來強化用戶的情感體驗和心理上的滿足。筆者認為,將設計焦點從物理創新轉向心理層面的探索,不僅能夠為鐵鎚等傳統工具的設計注入新的活力,還能夠為設計領域帶來更深入的用戶體驗導向的設計思維方式。同時,如何協助設計者從以更有效率的方式評估構想也是值得探討的議題。

    This study explores the application of experiential design methodologies and brainstorming techniques in the design of hand tools, specifically hammers, with a focus on enhancing the design thinking process and psychological benefits. Despite the physical functionality and structural design of hammers nearing perfection, the pursuit of innovation through improved efficiency, ergonomics, and safety reveals its limitations. Thus, this research aims to enhance the emotional experience and psychological satisfaction of users through the application of design methods, thereby expanding the innovative space in hammer design.
