Application of the Integrated QFD technique in the Design of an Innovative Machine for Cleaning the Drinking Water Tank

摘要

Due to the growing population and demand for clean water consumption, this research aimed to employ the Quality Function Deployment (QFD) to design and construct an innovative process for production of clean drinking water for small and medium enterprises. The QFD integrated various consumer-oriented product development techniques including Kansei engineering concept, the Theory of Analytic Hierarchy Process (AHP) for the selection of design parameters validated by users and the Theory of Inventive Problem Solving (TRIZ) to solve problems that originated from the new product. The innovative machine cleaning drinking water tank has a capacity of 360 units per day, a work methods reduction of 10.89%, and an employee reduction of 23.81%. The results of the test showed that the user satisfaction was very high.
