The paper aims to better meet the emotional cognition of users and modern interior design requirements of ceramic daily necessities, as well as to promote the usage, making ceramic daily necessities possess modern elements. Taking cobblestone-like ceramic batching tank as an example, the appearance design of batching tank is studied by using multi-index orthogonal test combined with imitation design and user emotional cognitive evaluation. First of all, according to cobble appearance and product elements, four factors and three levels of orthogonal table are established. Secondly, Kansei Engineering is used to select two most appropriate vocabulary, and Likert 7 scale is used to quantify the users' emotional cognition of each scheme. At last, based on the quantitative data of users' emotional cognition, the range analysis results and variance analysis results are combined to obtain the best appearance modeling scheme to meet users'emotional cognition. The imitation cobble ceramic dressing tank appearance design is completed, and a research idea of appearance design of ceramic daily necessities combining imitation design and user emotional cognition is established. Through the combination of imitation design and user emotional cognition, the product, the designer and users can be closely linked, the ceramic daily necessities can be more accurately optimized, and the optimal appearance design parameters can be obtained. At the same time, it provides a reliable reference for the future ceramic daily necessities design.
