WTW for an advanced technology that is logistically unfeasible in-universe, but exists to cover up the fact that the producers don't have the special effects for the more logistically easy option?

Famous examples of these kinds of tech are the beam teleporter in Star Trek (designed to cover up the fact that the producers didn't have the means to depict the ship landing, which would be far easier in-universe) and the morph ball in Metroid (designed to cover up the fact that the game designers couldn't animate the far easier feat of having Samus get on her belly and crawl).
