創造的工学設計支援システムの構築: 第2報，品質工学手法による創造的思考プロセスの評価

摘要

In recent years, industrial designers are required to design creative products in a short period of time. Attractive product is changed significantly by requirement definition and conceptual design phases. The Quality of product concepts, which is result of these phases, depend heavily on the creativity of designers or development teams. It is difficult that a computer-aided system supports a creative and inventive thinking process, and searches a creative design solution. To overcome these difficulties, authors developed a systematic approach of the creative and inventive thinking process called Creative and inventive Design Support System (CDSS). In this paper, its validity is examined by using to the Design of Experiments (DOE) and the Taguchi Method. From these evaluation results, it is confirmed that creative design solutions can be searched by using the creative and inventive thinking process of CDSS.%製品の魅力に影響を与える要因は，製品の外観や信rn頼性もさることながら，「製品コンセプトの作成」といrnった概念設計フェーズに担うところが大きい．また，近rn年の製品開発サイクルの短期間化や要求の多様化に伴rnい，本フェーズに対する十分な時間の確保や要求間の矛rn盾解決がより－層困難になってきている．さらに，1つrnのヒット商品を輩出するには，3,000以上のアイデアがrn必要であると言われている．このことからも莫大なコrnンセプトの輩出が必要となる．
