The effects of time and incubation on design concept generation
More ideas and a greater variety were found with additional time (2h versus 50min). A two-day incubation period helped novice designers break fixation. For higher quality concepts, additional consecutive time is better than incubation. For more novel concepts, additional consecutive time is better than incubation. For efficiently generating novel, feasible solutions, a 50-min session is best.
