本文以積木立體造形設計為個案研究主題，從心理層面的心理表像運作模型與完形心理學知覺組織準則的角度切入，此為理論基礎，探究設計者在造形創作歷程中的思考邏輯與運作模式，解構系列積木之設計。接著再以物理層面從材料結構方面說明具體實務的經驗觀點，透過實際製作流程，加以建構及創作各式造形，並據以解構設計者如何將心理表像轉化為具體實像，發展精粹造形設計的原則。

In this paper, we present a case study of three-dimensional form design with building blocks. Based on the combination of the psychological models of mental image and Gestalt theory, the design logic and mental model of the designers are described. The work flow of form design with building blocks is conducted and explained. Physical constraints and considerations about building blocks are discussed. The design principles are then extracted from the designer’s experience. We wish the result can explain how the designer transforms the mental image to real object image in the practical design of building blocks.
