In order to optimize and upgrade the intelligent milk machine, solve the problems encountered during the operation, a intelligent milk machine that improves the user's operating experience was designed by analyzing the users' behavioral contacts. The users’ behavior were observed to identify the touch points of using process and sort the contact priorities. Moreover, intelligent milk machine was designed by analytic hierarchy process. According to the design method, the demand point was transformed into a design opportunity to construct a intelligent milk machine design framework. Based on user behavior, intelligent milk machine was produced for the users to operate it conveniently.
