They do do SOMETHING. Putting multiple fragments in the analyzer unlocks the blueprint exponentially faster.

Other than that, since they spawn semi-randomly in their prescribed zone, the game needs to spawn a bunch in in case many of them spawn in difficult or impossible to reach loacations. Since the analyzer holds for, I'd be willing to bet that you'll eventually have to find four fragments to unlock the BP.
