The work aims to transform the idle space in scientific research institutes by a collaborative design method to improve the quality of participation in the process of science communication and summarize the path according to the practical results to provide a certain reference for similar design activities. The overall research was divided into four parts:conception, practice, verification and summary of the design scheme. Firstly, the conception stage was divided into two parts:one was the questionnaire survey based on Kano model and the other was the discussion combined with focus group and in-depth interview, aiming to obtain and transform the needs of users. Secondly, the practical stage relied on the three kinds of professional knowledge of environment, product and video transmission, and materialized the needs through the cooperation of various branches of design science. Thirdly, the POE model was selected to analyze the results to evaluate the effect of participation process optimization. Finally, all kinds of data in the above three stages were summarized, and theoretical summary was carried out with experts in CAS. The established scheme was completed on schedule and satisfied the needs of CAS. All relevant departments cooperated with each other to help the team collect the materials needed for the experiment. The most important characteristic of collaborative design is to coordinate the benefit correlation and achieve the best benefit. As far as this study is concerned, CAS has the knowledge of science communication and the experience of holding "Science Cafe" activities for a long time, which is the fundamental basis for the realization of the practice objectives. The discipline related knowledge mastered by the team from Beijing University of Chemical Technology and the inherent visual advantages of design discipline are the basis for the completion of various design tasks. The valuable suggestions put forward by teachers and students, administrative and logistics staff make this practical study more reasonable. It is the breaking of the barriers between the three that finally optimizes the process of scientific participation and produces certain social benefits.
