What is the main purpose of brainstorming in engineering design?

The main purpose of brainstorming in engineering design is to generate innovative ideas and solutions. This creative process allows engineers and designers to explore a wide range of possibilities without the constraints of judgment or criticism. During brainstorming sessions, the focus is on quantity over quality; participants are encouraged to share all ideas, no matter how unconventional. This open approach often leads to unexpected and innovative solutions that might not emerge during more structured decision-making processes.

The essence of brainstorming lies in harnessing the collective creativity of a group, which can enhance problem-solving and lead to breakthroughs in design. It is a critical step in early design phases, enabling teams to consider various perspectives and approaches before narrowing down options for further evaluation and development.
