Not long ago, I purchased a universal airplane/auto adapter. There was a packaging insert that exhorted me, the user, to NOT insert the plug the wrong way. There was even a “helpful” green line to help me line up the proper orientation (pictured at left, click for a larger view).
The problem was…. well, the plug was properly error-proofed. It was impossible to insert the wrong way. Great design.
So why the packaging insert? Why the green line? Seems like the “waste of overprocessing” to me. Extra helpful or unnecessary? How would you vote if it were your company? Do you do this to protect yourself from customer complaints, those who *do* try to force it together the wrong way?
