abstract
Background When there are various problems in the design process, it is necessary to prioritize problem solving. This study attempted to define and prioritize the problems raised in toast devices by applying the affinity diagram and the DEMATEL method. Methods The top three target toast devices were selected through the sales ranking of the domestic(Korea) open market, and problems were derived by analyzing the recent 100 product reviews for each product. Based on this, three experts and four undergraduates participated to derive priorities by implementing the affinity diagram and the DEMATEL method. Result As a result of performing the affinity diagram, the problems were one level structures with eight factors. And based on this, through the DEMATEL method, the order of 'usability/functionality', 'quality', 'product size', 'washing', 'code length', 'uniform heat transfer', 'slot size', and 'smell on primary use' could be confirmed. Conclusion Since the DEMATEL method is based on adjacent matrices, high-priority problems are highly related to other problems, which have the effect of solving other problems. This study attempted to solve the usability/functionality problem by simplifying the toast device. As a result, it is expected to improve to ‘cleaning’, ‘slot size’, and ‘smell on primary use’ by designing it as an open type.
