Design and Fabrication of Super Water-Saving Toilet System by Theory of Inventive Problem Solving (TRIZ)

창의적 문제해결 이론(TRIZ)를 활용한 초절수형 양변기 시스템의 설계 및 제작

This paper describes the design and fabrication process of super water-saving toilet bowl system by the theory of inventive problem solving (TRIZ). The physical contradiction in TRIZ is defined to obtain the conceptual design for saving water in toilet bowl system with preventing the bad smell from septic tank. The super water-saving toilet bowl system is obtained by using the separation principle in time for resolving the physical contradiction. The consumption of water in the prototype system fabricated, is estimated about $3{\ell}$ comparing with $13{\ell}$ of that in conventional toilet bowl system. The noise from water in the prototype toilet bowl system is decreased by 1/3 of that in conventional toilet bowl system.
