What's it called when an inventor's invention backfires on them? - eviltoast

Is there a name for this specific concept? Where somebody invents something (to do them good) but then that thing turns around and backfires on them?

      Well, not with that attitude… ;-)

      Nah, fair enough - as I said, I can’t speak German, so was just mucking about trying to get something that might be plausible. Thanks for clarifying.
