FWIW, "seriously contributing to this kind of problem" sounds basically the same as "pushing the envelope" to me. They both suggest contributing something novel and useful.

They are basically the same thing.

What are not basically the same thing are "he started seriously contributing to this kind of problem after a week in the woods" and "he spent a week in the woods a year ago and is ready to start contributing now. A year after that week in the woods."
