Numerous studies have shown the value of introducing cognitive supports to encourage the development of creative ability, and researchers have developed a variety of methods to aid in generating ideas. However, design students often struggle to explore more ideas after their initial ideas are exhausted. In this study, an empirically validated tool for idea generation, called "Design Heuristics," was introduced as a means of productively pushing past creative exhaustion in an industrial design course at a large Midwestern university. Students worked on a simple design task on their own, generating an average of 6.1 concepts in a 30-min session; then, after 10 min of instruction on the "Design Heuristics" tool, students generated an average of 2.8 additional concepts for the same task using Design Heuristics for an additional 30 min. The concepts created in this second session using Design Heuristics were rated as higher in novelty, specificity and relevance. These results suggest that students benefit from introducing support tools following a period of working on their own ideas. Once their own ideas are exhausted, students may be more open to using and learning from support tools, and these tools may support skill development while producing higher quality outcomes.
