I have managed senior engineers in almost every discipline who were SMEs in their area, and either much smarter or skilled than myself. A way I dealt with this was to ensure the discussion was on the project/problem - and that people had input on the solution regarding its feasibility. i.e. "OK, team, tell me why or how this solution can fail" and "OK, what is the negative impact of doing it this way?" "Can you see any holes in this method?" The idea is that people can voice concern about failure conditions for a solution - and it keeps them focused on the project/problem/solution and less on their ego or interpersonal communication between team members. So if an engineer wants to do something that will have an impact on someone else should that thing break, then it can be weighed into the value of that solution.
