Would it bother you if I started re-wrote the Wikipedia article on the hot dog in an attempt to convince everyone I invented it? And if people started believing that?
If you've "invented" some relatively simple combination of existing pieces, the only sensible and humble thing to do is acknowledge that you're probably not the first one.
When you pull the two string ends of a standard knot at the same time, the loop shrink and pull out of each other at the same time. Just figure out how to do that backwards and you probably have Ian's Knot or something very close.
