To me, a "critical thinker" is someone who can see the underlying assumptions, and challenge them.

As a mechanical engineer, "creative problem solving" may be more beneficial. Note: That doesn't mean you don't challenge the "conventional wisdom" (what a critical thinker would do).

I am a visual thinker. I visualize the solution, and work backwards - visualize each component. Then, work the details. IMHO, if I can visualize the solution, then there is a fighting chance that I can get it to work.

Don't be afraid of people who say "it won't work" because what they usually mean is "we don't do it that way". If I can get the pieces working, and it solves the problem, then it doesn't matter if they never did it that way before.

Obviously you have to live within constraints of safety, cost, etc. Creative problem solving starts with "no constraints" (brain storming) or you eliminate potential solutions. Work the potential solutions to see if you can get them to fit within your constraints.
