Yes, I agree that the ideas can be generated through intuition. Intuition is a cognitive process, whereby, an individual makes decisions based on his cumulative knowledge and experiences. It is being called that 'Aha' feeling when one's internal search engine hits its mark. Many people refer to it as their 'gut feeling'. Although, structured and methodical approaches to generate ideas are important, but still intuition also plays an important role in idea generation if one learns how to use it.
