Integration of four-phase QFD and TRIZ in product R&D: a notebook case study

Worldwide demand for notebook computers has outstripped that for desktop computers. Today, notebook computer design and manufacturing is one of the most competitive of all electronic industry subsectors. Innovation and environmental friendliness (i.e., “green”) are both of increasing importance to notebook computer makers. Traditional strategies for NB design and manufacturing may be inadequate to meet steadily rising customer product expectations and environmental concerns. This study aimed to develop and market an environmentally friendly and energy-efficient notebook computer. A four-phase QFD plan, based on a series of matrices, was developed to create an innovative product that (1) satisfied customer needs, (2) fulfilled target specifications, (3) achieved target cost objectives, (4) was achievable within a set development timetable and (5) realized high production yields. Contradictions among plan objectives represent a threat to overall project success. This study identified major QFD contradictions in the spheres of engineering and administration and applied a methodology integrating TRIZ inventive principles, a contradiction matrix, and eco-efficiency elements to achieve green-design solutions.
