idea means?

(1)
A 'solid idea' is a concrete idea. It gives us the complete picture on how to make things work. Every one can follow the idea and translate it into action.

Example: Our manager always brings up solid ideas in the meeting.

(2)
A 'universal idea' is an idea that is always used and always works, no matter what.

Example: Cost saving is a universal idea in a recession.

(3)
Please note that it should be 'in the light of' (not 'in light of').

in the light of this = with the help of this

Example: In the light of the court's decision, we are able to proceed with our claims
