IMO, both innovation & philosophy involve thinking. Thinking at a deeper level than usual. (technically you are 'thinking' when your brain 'commands' your hand to pick up the spoon & feed you, but I am referring to thinking in its more complex usage).
When I 'innovate', the process involved thinking, I need to find a scope, a need, a method to fulfill that need & then think how to implement it & implement it.
Philosophy is not much different. When I am musing about life, the purpose of life and such other rudimentary concepts, I am often trying to find a need, for life, a way to explain what is happening & why is it happening & apply it to life.
So is it just that they are 2 different types of thinkings? Maybe. Yet to figure it out.
This was my answer to a question about the relation between innovation & philosophy.
