A co-worker in the early 90s (he was a tech writer) told me of a cost savings device he invented in the 80s at Texas Instruments to fix a process where occasionally a mirror on a very expensive piece of military camera gear got scratched (I think it was during field disassembly). It was basically some forceps with more metal welded on to make them longer and that allowed you access via a different route than where the mirror was installed. TI gave cost savings awards as a percentage of money saved and he did very, very well with that little invention.
