建構圈椅風格的造形要素及其操作之探討

A Study on the Key Form Elements and the Operation in Constituting the Product Style of 'Loop Chairs'

本研究透過一風格認知實驗及迴歸分析等統計方法，探討構成圈椅風格認知的造形構件及要素為何，其相對重要性為何。結果顯示，最主要的造形要件為圈背，其次為靠背板，之後依次則為椅腳支架、椅腳圈框、雕飾及扶手立柱。本研究再以圈背之造形要件，探討其長度、角度及形狀在何種變異範圍仍能被認知為圈椅風格。實驗結果顯示，當圈背長度超過扶手立柱，角度在20°與70°之間，外形稍變成ㄇ字形，但仍保有大的弧曲線與圓角時，仍可保有圈椅的風格認知。這個研究結果顯示特定風格與造形要素之間的明確關係，及其可能的操作特性。其可直接應用來建立圈椅風格之家具，更提供一風格建構與操作之理論架構。

In the first part of this study, an experiment on the style of 'loop chairs' has been conducted to find out the key form elements and their related importance in constituting this style. The result reveals that the 'loop back' is the most influential element, while the 'back slab' is the second one, and 'seat supporting frame,' 'reinforced rods for legs,' carved decoration on the back slab,' and 'struts under armrest' are the following elements in the descending order of influential strength on the perception of this 'loop chair' style. In the second part of this study, we have altered the length, the angle and the shape of the 'loop back' on a loop chair in different degrees to see how these alternations will degenerate the perception of this style and how far these alternations can be taken within the limit of perceptibility of this style. The result shows that as far as the length of the loop back extended beyond the location of the struts under armrest, the angle of the loop back kept between 20° and 70°, and the transformed shape of the loop back preserved the curvilinear and rounded corner characteristics, this 'loop chair' style can still be recognized. This study assures us that the clear relation exists between a specific style and some relevant form elements of a product which can be operated within some acceptable ranges. The findings of this study can not only be directly applied in establishing the 'loop chair' style in furniture design, but set the foundation for a general theory in style constitution and operation.
