Application of quality function deployment in product design and development: car seat case study

Quality Function Deployment (QFD) plays a big role in product design and development. It is consisted of several techniques which are very useful and suitable to be applied in whatever field. This project focuses on how the QFD is implemented and applied in designing a car seat. Ergonomics study is important because it helps to analyze the human posture behavior. According to QFD, the process of designing a new product starts from customer’s requirement. Then some of concepts are developed as the early picture resulting from the product design specification and customer’s requirement. Other techniques were applied such as morphology chart, concept generation and concept screening. These techniques were then lead into concept selection using weighted scoring method. CAD was performed by using SolidWorks CAD software. An ergonomics analysis were also studied to see the final score of the design using RULA analysis. As the result from QFD process, a new ergonomics car seat design is developed.
