in spite of taking the sign conventions during the derivation why should we use it again while doing the problems?

The signs need to be taken care of everytime you do any problem. Derivation is also a sort of problem and so, in order to derive the right thing, you need to keep sign conventions in mind as well as while solving any problems.
