This research sets up a conceptual design of a future mobile healthcare device through the quality function development (QFD) with the analytic network process (ANP) and the theory of inventive problem solving (TRIZ). We use a three-stage QFD in order to consider the customers’ requirements, extend the whole design process, and calculate the weight of the house of quality (HOQ) by implanting ANP. Some contradictions to the top-side items of the “house” (or “how” parts) are able to be overcome by TRIZ. After integration of the three methods, the analysis characterizes the features and their priorities for the future device. We believe that the device will push the healthcare system to be more efficient and provide a better service for an aging society.
