Sometimes it's hard to distinguish between factual knowledge and just cleverness. There's no reason a bumpkin fresh off the farm can't be curious about what makes something tick, so they look under it or break it open - and whaddya know, they find a hidden thing. It's really up to the DM to say no, your character wouldn't know to do that. The intelligence you show when you figure out a puzzle or a trap could make total sense as the same spark that made the naive character want to leave the farm and explore the big wide world.
