| This paper strives to establish the basic concept of the product design for jovial mentality and its related theories. It starts with the jovial mentality, namely something that capable to evoke fine memories and life experience of the users of the products, which is brought by the products interacting with the users in course of the usage of the products. How could the products remind the users of fine memories or association, how could the products bring the users worthwhile aftertaste in course of the usage of the products? Life is the jumping-off point of the design. From the angle of the users'emotion, the design is to design a new usage style, the design is to design the products that are real convenient, handy, tallied with the users'emotional request. Therefore, to make a thorough research of the mode of jovial mentality brought by the usage of the products, and to seek for the track of the design of usage-act-mode, will be an affirmative task.Part two deals with the study on emotional design of the products. After studying the actuality and the trend of the development of the emotional design of the products foreign or domestic, it represents the relations between the products and the users, from the users'perceptual images and aesthetic mentality, for accomplishing communication or communion with the products. Let the users accept the products, meanwhile, let the users'emotion resonate with the designers'thought. The author holds it as a kind of communication among the designers, the products and the users.Part three is engaged in the analysis of 11 kinds of the usage-act-mode products with the theory of the product design for jovial mentality. The paper makes efforts to explore the possible mode of the product design for jovial mentality by summing up the serial design modes. The product design leaves space for the users'association, so when the products are put into use, there will produce product-revert thought, understanding, and jovial psychological feedback.Part four is engaged in the analysis of the analogical cases of usage-act-mode products and the cases of the deep-seated cultural scenario. After consummating the mode of the product design for jovial mentality, the author discloses that the best way of the design mode among interaction is to develop the association, and summarizes the theoretic process of the product design for jovial mentality. The process is to learn the macroscopic cultural scenario mode firstly, and then proceed to subdivide related motion with the using-motion-mode design. So the development of the design mode is from the development of the macroscopic cultural mode to the subdividing research of the sub-mode.Part five confirms the possibility of the theory of the product design for jovial mentality by an actual conception design with the usage of the design theories process offered above. The author argues that taking the theory of the product design for jovial mentality to solve the problem of the users'mentality, can be applied to the primary stage of the design conceiving so as to cultivate the innovational ability of the designers. |
