I like the idea of having some sort of a small disc, probably on the opposite side of the drive pulley from the blade, that gets utilized for harnessing the centripetal energy. You could have some sort of a pin that gets shoved in, like a stick in bike spokes, when the trip mechanism activates. Additionally, a brake could be applied to that same disc. The disc would likely need to be replaced, but it could be a 5 or 10 dollar replaceable thing as opposed to a $100 blade.

The clutch idea is also a good one, and could be incorporated so that there are multiple points of safety. With all of this, you may still need some sort of “cartridge” or something.

Of course, since a solenoid takes relatively long to activate, you could have some sort of a small piston or hammer that exerts a downward force on the front of the arbor so that it forces the blade under the saw about the rear pivot point. This could make it so that you could just push a reset button, move the mechanism back in to place, and go your merry way.

Sure all of these ideas would take additional refining and work to get right, but there are some possibilities. And something is surely better than nothing.
