Also not sure about a name, but in Greek mythology, there's Daedalus. He built a massive maze, which was then used against him to imprison him & his son. Daedalus crafted wings out of feathers & beeswax to escape the island of Crete, but his son Icarus flew too close to the sun. Melting the wax, destroying the wings, and drowning in the sea.
To be fair, he gave adequate warning to Icarus. The fault with the wax wings doesn't lie in the inventor or invention, but pure simple user error not following the directions.
Irony can be used in many situations. I want a German word that specifically refers to this situation. Something like Erfinderhybris; I just slammed Inventor and Hubris together.
