Design ideation is a core stage in the design process that begins with a design brief and results in a range of design concepts from which solutions can be selected. The success of design ideation relies upon designers’ creativity and ingenuity. In current practice, design ideation tends to be an ad hoc process which combines the designer’s experience with techniques such as sketching, brainstorming, and mock-up to develop creative solutions in response to the brief. There are notable differences in ideation performance between novice and expert designers in that experts tend to follow a more systematic process, and have more experience and knowledge of previous designs to draw on. Design ideation is more challenging for novice designers who have limited experience on which to draw and no systematic process to follow. This thesis provides a method that enhances the design ideation performance of novice designers by providing a systematic design ideation process for them to follow, and a database and associated visualisation method that gives them access to previous designs. The method was assessed through empirical evaluation experiments conducted with 101 students in the UK and South Korea. This confirmed that the method improves novice designers’ generation of creative solution concepts in response to a design brief. The research makes four contributions. The method, Knowledge-Enabled Design Ideation Method (KEDIM), provides a systematic design ideation process that includes three steps. The first step draws on a Database of Design Cases (DOS) that is supported by a database schema. DOS is a part of the research contribution that provides a structure to capture case data. DOS was validated through population with 540 design cases, and through use in the second stage of KEDIM, Perceptual Mapping Generation Software (PMGS). The core contribution of PMGS is its visualisation method that brings together selected design cases from the database and presents them in a way that enhances novice designers’ abilities to draw analogies. The final contribution is Systematic Brainstorming (SBI), where these analogies are developed through a set of specific ideation themes alongside solution concepts. KEDIM, through these three tools, improves the effectiveness of novice designers ideation by increasing the number of solution concepts generated when compared with students not using KEDIM responding to the same brief.
