It is already the solution, sorry if you can't see it. It might help you to research what I've written, the proofs are all there. All the best, I guess it's unlikely we will ever work together.
You should realise also I've never met an Engineer who would say something is impossible with no proof. Personally I wouldnt rate such an Engineer very highly at all. I would be inclined to say you are in the wrong job, you might do better as a politician or lawyer, you know one of those trades where everything is arguable.
