Both impression and function are important issues for design creation. These two factors compose meanings of designed objects. Design process can be viewed as a process of development of the structure of meanings. This research presents a new design methodology by focusing on the structure of meanings. The processes of search and evaluation of meanings form the fundamental phases of this method. In order to facilitate the searching for the meanings, the WordNet lexical database and an existing visualization tool (Visuwords) are adopted. The basic tool used for evaluation process is the WordNet::Similarity software, measuring the relatedness of meanings in the database. The measures of relatedness of meanings are developed as convergence criteria for application in the processes of evaluation. In this research, the steps of the design methodology, including the search and evaluation processes involved in the development of the structure of the meanings, are elucidated by carrying out demonstrations of proposed system.
