Here’s a great example of a product paradox: This is a set of packaging cutters that are designed to “open anything”. In this world of hard plastic packaging, this tool can save you from cutting yourself with a knife or underpowered scissors.
Here’s the flaw in this company’s strategery: You need a pair to open the packaging on this pair. That’s right, they forgot to make it easy open!
NOTE: Make sure your product doesn’t create the very problem it purports to solve.
