My understanding was that most of the “modern” items (excepting things like the lamps in Azkhaban) are magic-based items, they simply got the ideas from muggle items. There’s no obvious indication that Minerva’s clock was purely mechanical; the one Trelawney used had voice recognition, for example.

Even torches are a “muggle-inspired technology” if you think about it. Purely magical lighting would be a glowing globe, or even unexplainably-lit rooms like the Wizengamot hall, there’s no reason to have it shaped like a torch (albeit proximity self-lighting and ever-burning) unless you got inspired by real torches and just went on with tradition, and at least many of those are probably not created by enchanting a manufactured torch. (Given how many there are in Hogwarts, and that you seem to find them even in rooms that didn’t exist yesterday, I’d guess the weird self-building architecture just includes most of them by itself.)
