like the umbrella wedge/spring to make it open automatically.

That to me is a very specific algorithm. It's a simple mechanism but putting it together might be a bit tricky.

That's very similar to SHA, it's a fairly simple set of mechanisms but the actual composure of those ideas into something that works as well as SHA does takes very specific research experience. It's not at all an abstract idea, it's a very concrete and specific set of operations that you invented first.

Imagine if the patent was "an umbrella can open itself with the push of button" no further details. That's close to the level of detail some software patents are argued at and effectively what the "put a game in your loading screen" patent was awarded on.

You can't patent the idea that "an umbrella should be able to open [somehow]" so I likewise think it's ridiculous that someone was able to parent "your game [somehow] runs another simpler game before it runs."

Patents should be to protect very specific research so that the private sector can do said research and profit from it. Patents should not block out broad concepts. The patent in the video game situation was and should've been ruled as bogus. It's not the type of thing anyone needed to research or think about, you just literally go "what if I added a game to my loading screen" and you're in violation.
