テレビの商品ラインアップの展開におけるデザインの考え方: 商品ラインアップにみるデザイン手法に関する研究(4)

This study discusses the wide-frame and the standard-frame cathoderay tube TV sets, particularly the product line-ups and designs of these two types marketed by five leading manufacturers during the past six years, these two categories having higher component ratios. The product line-ups for the two categories are based on improved performances and functions for cathode-ray tubes and image displays, but their process of changes were different by manufacturers.Examination of new models for each of these six years in regard of the common features of the outside designs revealed "unified type design" where all models had the identical design, and "distribution type design" where all models had plural designs.The latter could be classified into three based on the presence/absence or difference of viewpoints common to design; "type dependent design", "frame-size dependent design" and "distribution type design" where the design was not uniform.Differences in the design philosophy as well as differences in the types and frame-sizes of new product line-ups were considered to be reflecting differences in merchandising strategies and the attitude toward production costs of manufacturers.
