Key Findings
- 01Brainstorming and morphological analysis demand more cognitive activation across the prefrontal cortex (PFC), particularly in regions associated with divergent thinking (right DLPFC, ventrolateral PFC).
- 02TRIZ elicits more cognitive activation in the left DLPFC, associated with convergent thinking and judgment.
- 03Morphological analysis and TRIZ enable greater coordination between brain regions compared to brainstorming.

Design takeaway
When aiming for efficiency and focused problem-solving, consider structured ideation methods like TRIZ. For initial broad idea generation, techniques like brainstorming or morphological analysis might be more appropriate, but be mindful of the higher cognitive demand.
How to apply
During the early, divergent phases of a design project, utilize brainstorming or morphological analysis. As the project progresses towards selection and refinement, transition to more convergent techniques like TRIZ or structured evaluation methods.
Project actions
- 01When describing your ideation process, consider mentioning the cognitive demands of different techniques.
- 02If you observe differences in your own or your team's engagement with various methods, relate it back to cognitive load and brain activation patterns.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Uses neuroimaging to provide objective data on cognitive processes.
- +Compares multiple established ideation techniques.
Limitations
It's difficult to directly measure brain activity without specialized equipment. You can infer cognitive load through proxies like time taken, number of ideas, and participant feedback.
Reliability & validity
The use of fNIRS provides a degree of objective measurement (reliability). The validity is supported by correlating brain activity with known cognitive functions (divergent vs. convergent thinking). However, the sample size and specific task design could influence generalizability.
Think critically
To what extent do individual differences in cognitive styles or prior experience with specific techniques influence the observed brain activation patterns?
Design Principles
"Cognitive load in ideation can be modulated by the structure and focus of the technique employed."
Understanding how different ideation techniques impact cognitive load and brain activation can inform the development of more effective design processes and training methodologies. This knowledge allows design teams to select or adapt techniques that best suit the specific stage of design and the cognitive demands required.
What This Means for Your Design
Different ways of coming up with ideas use different parts of your brain. Some methods, like TRIZ, make your brain work more efficiently by focusing on specific problem-solving areas, while others, like brainstorming, use more brain power for exploring lots of possibilities.
How to use in your project
- 1.Reference this study when discussing the rationale behind choosing specific ideation techniques for your design project, particularly if you are exploring different methods.
- 2.Use the findings to justify why a particular technique might be more suitable for a certain stage of your design process.
