Brainstorming

Brainstorming is a very good concept and technique to get a solution to aproblem and to innovates something new.
Brainstorming combines a relaxed, informal approach to problem-solving with lateral thinking. It asks that people come up with ideas and thoughts that can at first seem to be a bit crazy. The idea here is that some of these ideas can be crafted into original, creative solutions to the problem you're trying to solve, while others can spark still more ideas. This approach aims to get people unstuck, by "jolting" them out of their normal ways of thinking.

During brainstorming sessions there should therefore be no criticism of ideas: You are trying to open up possibilities and break down wrong assumptions about the limits of the problem. Judgments and analysis at this stage stunt idea generation.

Ideas should only be evaluated at the end of the brainstorming session – this is the time to explore solutions further using conventional approaches.
