There are some problems whose solution just says there's no solution, as such is impossible, such as Bascule's Book. Other times there are variations on a puzzle that are offered in the comments on a given puzzle, such as my latest comment on Don't Be a Square, where I propose a generalization for a 270-degree arc, which I have no idea how to solve.
