I am fascinated by the idea of "the underlying sociological and cultural factors" that go into the way a sociocultural group engages in the task of engineering (within this context: the scientific approach to problem-solving).
I realize this is a poor explanation, but an example of the phenomenon should be able to clarify what I attempt to describe. The underlying structure of the thought process behind how the Russian conception of war resulted in divergent, yet ultimately superior tank design. The cultural influence on the way tools that fill a universal need are themselves constructed. Like how western saws cut on the pushstroke, but eastern ones on the pullstroke. the saw is almost the same, and exists to serve a shared need for a tool. yet the simplest thing diverges completely.
I think those questions about the design process fall within the domain of the philosophy of technology. Maybe check out the Stanford encyclopedia of philosophy page on the Phil of technology.
