Advanced Product Robust Design (QFD, TRIZ and Taguchi DOE Integration)

Seminar Content

This is a three day course that focuses on the application of QFD, TRIZ and Taguchi DOE in product development, understanding customer’s needs, solution proposal of creative product design, and robust design of product realization process targeting customer satisfaction.

QFD (Quality Function Deployment) has been successfully applied by TOYOTA in vehicle design since 1970’s. QFD effectively establishes the relationship between Voice of Customer (VOC) and technical parameters with House of Quality, and also deploys with cascade to all the levels of product realization within enterprises.

TRIZ (Creativity Techniques) is developed by Genrich S. Altshuller (Russian) based on 2.5 million patents and 1500 man-years of research. TRIZ can dramatically improve the creativity of engineer with the systematic skills. It can be used at all the stages of the life cycle of the product to improve the quality of the product, expand the market, protect knowledge copyrights as well as research on the new product.

Taguchi DOE concentrates on parameter design. With the parameter design, the test planning can be developed, the Noise factor can be reduced based on S/N ratio, thus improve the robustness of the product.

QFD sets up the direction and target of the product design, however, QFD may not be able to find out how to break through the bottle neck and create an optimized solution.

TRIZ can resolve the issues of “Bottle Neck” with all problem/conflict solving skills, and also create the new product design.

DOE (Taguchi) can strengthen the parameter selection process which may not be effectively provided by TRIZ. DOE can be applied to reach the best parameter combination for the product.

The integrated application of QFD, TRIZ and Taguchi DOE can effectively improve the product design process and achieve the robust product design for custom satisfaction.
