New Design of Hydraulic Paving Block Machine Using QFD and DFMA Method

Abstract

Intense market competition makes companies continue to develop or create an innovate products based on the needs of the customer. This study aims to design a more effective and efficient design of the hydraulic paving block machine as well as to minimize the time and cost of assembly/production using the QFD integrated DFMA method. A private company engaged in manufacture the industrial machinery and manufacturing equipments, one of which is hydraulic psving block machine was used as a case study of this research. QFD was used to identify the company’s problems. Based on the QFD phase I method, the result showed that there are 5 of 7 attributes that have high valued added by technical characteristic, i.e. cost and time of installation, cost of component and assembly, total components, and design efficiency. Meanwhile, there are 2 of 3 critical part attributes in the QFD phase 2, i.e. mold and frame. As a result, the QFD integrated QFD save the assembly time of the paving block hydraulic machine from 6,605.07 to 6.045.47 minutes, design efficiency increase as 1.39%, and save the cost of installation as one million rupiahs.
