Sadly you can't skip to engineering a solution. If you're designing a device getting quality requires rigorous specification and testing, in a feedback loop with design. What you describe might be a solution, but you can't know it's worked without that testing, and it's premature/risks over-engineering unless the testing shows you need it.

It's the time and money of testing that is usually being skipped, not the engineering itself. (Although many manufacturers might sacrifice quality to save the cost of what you describe anyway :( )
