Using TRIZ and human-centered design for consumer product development

TRIZ is increasingly being applied to consumer product development, in which products have to solve more than just technical problems, they have to provide compelling solutions to consumer needs. This paper discusses the use of TRIZ together with Human-Centered Design (HCD), a design methodology evolved for consumer product development. Using a case study, we illustrate why understanding user needs in consumer product development is particularly important, and then compare TRIZ and HCD methodologies. To better understand the appropriate use of TRIZ in consumer product development, we present a framework of Use, Usability and Meaning. Design situations where the emphasis is on a product‟s Use stand to benefit most from TRIZ methods, whereas for product areas with strong Meaning attached, HCD methods provide the most guidance. We finish by presenting some opportunities for successful integration of the two methodologies.
