In Taiwan, people who enjoy traditional Gongfu tea are becoming older and older, while the younger generation has many alternative beverages to select from. In order to sustainably pass down traditional tea-drinking culture, this study has incorporated concepts and methodologies of the peak-end rule, customer journey maps (CJMs), quality function deployment (QFD), fuzzy analytic hierarchy process (FAHP), and fuzzy comprehensive evaluation based on entropy, resulting in the development of a set of tea utensils tailored for a novice or beginner tea maker with the purpose of improving the tea-drinking experience of the younger generation. In this study, the ranking of the importance in regard to six design requirements turned out to be: enhancing the sniffing experience (0.240); having ergonomic designs that facilitate a smooth process of pouring hot water into the cup (0.205); increasing the ease of storing tea utensils after brewing (0.162); enabling users to more precisely determine the strength of the tea (0.144); increasing fun while pouring tea leaves into the teapot (0.143); and having clearly designated space for placing each tea utensil (0.107). Through the experts’ evaluation, 66.6% of them rated the design outcome as “good” or “very good”, indicating that the innovative tea utensils developed in this study can effectively satisfy users’ needs. This study can be the supplement to the innovation shortage of tea-culture-related studies, establish the research framework in the academic field, and bring more innovation and potential to the field of the tea culture.
Existing medical masks have various disadvantages, such as the environmental damage caused by disposable masks, the discomfort and poor ventilation caused by prolonged mask wearing, and the lack of aesthetic design in mass-produced masks. Thus, this study used quality function deployment, the fuzzy analytic hierarchy process, and fuzzy comprehensive evaluation to research, develop, and design masks. The aforementioned methods were also used to determine the ranking of design requirements. The following priority ranking of design requirements from most to least important was obtained: reducing discomfort at the contact between the mask and the skin (0.265), avoiding foul odor inside the mask (0.187), convenient cleaning and portability (0.166), good airtightness (0.152), suitable aesthetic design for wearing in public and on social occasions (0.130), and reducing waste (0.100). Experts evaluated mask designs, and their opinions were subject to fuzzy analysis. Specifically, 50% of the experts evaluated the designs to be “good” or “very good”. Only 29% of the experts rated the design results as “average”. Thus, the innovative mask designed in this study can meet the needs of users, overcome the drawbacks of existing masks, and provide a feasible solution for the current COVID-19 pandemic.
