Brainstorming variants to favor creative design

Area of Science:

• Ergonomics and Human Factors
• Design Thinking
• Cognitive Psychology

Background:

• Creative design is crucial for preventive and prospective ergonomics.
• Existing user-centered methods often lack support for creative ideation.
• Brainstorming is a common technique, but its creative potential can be enhanced.

Purpose of the Study:

• To adapt the brainstorming technique to better support creative design processes.
• To investigate the impact of focusing on idea evocation versus constraint evocation.
• To determine optimal conditions for fostering creativity in design tasks.

Main Methods:

• Developed two variants of brainstorming: one for idea evocation, one for constraint evocation.
• Conducted three studies with diverse participant groups: designers, generalist teachers, and creative arts teachers.
• Varied instructions provided to participants: idea evocation, constraint evocation, or no specific guidance.

Main Results:

• Both idea and constraint evocation techniques positively influenced creative design outcomes.
• The effectiveness of each variant depended on the participants' background and the task's complexity.
• Specific instructions significantly impacted the creative process compared to no guidance.

Conclusions:

• Tailoring brainstorming approaches to focus on idea or constraint generation can enhance creative design.
• Understanding participant expertise and task demands is key to optimizing creative ideation.
• Modified brainstorming offers a valuable tool for improving user-centered design in ergonomic contexts.
