Table Saw finger saver

To make the table saw safer there is a great invention already on the market (sawstop):

The only problem with this - it destroys the sawing disk, the device itself and probably the motor since the shock wave may crash the rollings.

My suggestion is to have not as fast but some finger saver.

To save finger 7 which could be cut with the wood 6 the blade 5 with all the motor and the base 2 pushed down (diagonally since the disk is circle) by very stressed springs. The same detector as in existing saw saver tell when release the trigger.  Ratchet 1 prevent the saw to go back.
There will be a lot of noise but the motor could be saved.
