In order to make the product function configuration reasonable and the final output technical solution meet the user needs,the quality function deployment (QFD) method was introduced into the design process of moxibustion robots for home using,converting user needs into design needs and ensuring that the designed moxibustion equipment meets the home using needs and its competitive.The contradictory design needs derived in the QFD stage were analyzed,and the corresponding invention principles were found to solve it.Finally,the substance-attribution-function-causality (SAFC) model of U-TRIZ theory was used to construct a technical solution for each pair of technical contradictions and solve the corresponding technical contradictions.The results show that the combination of QFD and U-TRIZ can not only make the product construction reasonable,but also can effectively make the realization of functions conform to the requirements,which makes the design process more rigorous and facilitates the designer to quickly find a suitable technical solution that conforms to the requirement ratio.The technical solution designed with this method was applied for a patent for invention,which effectively verified the effectiveness of the method.
