Abstract

Conceptual design is the most important phase of engineering design process and the product cost is significantly determined at this phase and it has a direct effect on product innovation. However, academic and commercial design support systems have usually served embodiment and detail phase, namely with the aim of drawing, analysis, simulation. Design authorities envision that new generation CAD/E systems mainly will built on innovative conceptual design. An innovative conceptual design process must be developed in a structure that is comprehensive, systematic and inventive, and that includes all contradictions at the beginning of design. But, actual works being conducted on this subject focus usually on the improvement of existing products and the resolving only a single contradiction. Therefore, they are not sufficient to design especially original and innovative products. To overcome the challenge, we develop a new and innovative conceptual design process. The proposed model consists of Pahl and Beitz’s conceptual design approach, QFD and TRIZ. To prove the usability and the reliability of this model, a design case study is carried out. As a result energy-efficient, low cost, high performance, innovative solutions at the level of patents are obtained. This results show that this design process model will be successful in finding innovative solutions through the example of water filter design

Yeni ve İnovatif bir Kavramsal Tasarım İslem Modeli ile Su Filtresi Tasarımı

Öz

Kavramsal tasarım, mühendislik tasarım isleminin en önemli asaması olup ürün maliyeti ve inovatif çözümler genelde burada belirlenir. Buna karsın akademik ve ticari tasarım yazılım sistemleri daha çok sekillendirme ve ayrıntılı tasarım asamalarını kapsamaktadır. Yani; genellikle çizim, analiz, simülasyon vb. amaçlamaktadırlar. Yeni nesil CAD/E sistemlerinin ise temelde inovatif kavramsal tasarıma dayalı olacağı tasarım otoritelerince ön görülmektedir. Đnovatif bir kavramsal tasarım islemi; kapsamlı, sistematik, yenilikçi ve tüm çeliskileri dikkate alacak bir yapıda olmalıdır. Ancak bu konu üzerine yürütülen çalısmalar genelde mevcut tasarımları

iyilestirmekte veya bir çeliskiyi çözmektedir. Bu nedenle de orijinal ve inovatif ürün tasarlamada yetersiz kalmaktadır. Sorunu çözmek için bu arastırma kapsamında yeni ve inovatif bir kavramsal tasarım islem modeli gelistirilmistir. Önerilen model, Pahl ve Beitz’in kavramsal tasarım yaklasımı, QFD ve TRIZ’i içerir. Bu modelin kullanım ve güvenilirliğini test için örnek bir tasarım uygulaması yapılmıstır. Uygulama sonucunda

enerji-verimli, düsük maliyetli, yüksek performanslı ve patent düzeyli inovatif çözümler elde edilmistir. Böylece yeni tasarım islem modelinin inovatif çözümler bulmada basarılı olabileceği örnek filtre tasarımı ile görülmüstür.
