That's nonsense.  No one is asking you to reveal the design of your
company's next product.  However, you have some overall problem you are
trying to solve, and you have focused in on one POSSIBLE solution. Instead,
tell us about the PROBLEM, and we'll offer good solutions.

NO ONE will be able to give you a solution, because you have not described
the problem.
