Overdesigned → It is formed from "over-" (meaning excessively) and "designed" (from Latin "designare", meaning to mark out or plan). The word "overdesigned" means excessively planned or elaborately designed beyond what is necessary.
Think of something that is planned or marked out ('designed') in an 'excessive' way ('over-') — that's why overdesigned means too much design.
