Study on the Shape Image of Chinese Portable Tea Set -- Crack Cup by Using Triangular Fuzzy Number

In contemporary society, the pace of life is rapid and unrelenting, the crack cup, as a portable tea set, offers a convenient solution for individuals who enjoy drinking tea while on the go. This study seeks to investigate the evaluation of the visual image of a variety of crack cups. To this end, a considerable number of crack cup products were collected through Internet data collection, field research, and shopping websites. From these, 12 products with distinct shapes were selected as research samples. In the first stage of the study, ten individuals experienced in using tea sets were tasked with selecting the most suitable 40 adjectives from a pool of 140 adjectives collected. Subsequently, a semantic difference (SD) method questionnaire survey was conducted with a group of general consumers, and factor analysis was performed to identify six groups of adjectives that corresponded to the visual image of fast-food cup models. These groups were as follows: durable and lightweight, simple and practical, retro and elegant, fashion-forward, varied, and precise and meticulous. According to the research findings, a relevant database has been established for the subsequent design and application of crack cups. This database is founded on the evaluation values of various shapes' design intention, enabling designers to create products that cater to the diverse preferences of consumers regarding the shape image of crack cups. As a result, the design of crack cups can better meet the requirements of consumers.
