Isekai Craft Gurashi ~Jiyuu Kimama na Seisan Shoku no Honobono Slow Life~ - Ch. 33

While I know that it's likely the case (I never questioned the story reason for it), I just argue that it's bad writing. It would have been much better if Miyabi just made a comment like "Now, I wonder how to make a brake for it?" and then the craftsman brought it up.

At that point, the author would both highlight the other person, and not make a mockery of Miyabi. After all, even someone that can figure something out themselves would benefit from simply using an existing idea that already solves said problem.

Basically, I just complain about consistency issues here. There'd be no problem if he was stumped by something actually complex (like steam engine). It's a problem when he has shown problem-solving skills before, but suddenly having all the necessary knowledge cannot think of the most basic thing that is simpler than what he already made.

I kind of think it's a visualization problem than anything else. Miyabi's basically working off his imagination and skipping past a proper design process by going straight to the conclusion (bicycle brakes / modern-style brakes) instead of working out why the brake mechanisms are the way they are, even worse that it's the sort of engineering he's not really learned.

Arguably, this has been consistent with his character that he does tend to go straight to the conclusion of the results he wants to achieve, before running into the actual practical problems. Hell, it's been a thing since the arc where he wanted to impress the Duke but didn't really ruminate on what the Duke actually wanted out of the baths.
