try mixing the first idea (the solenoid powered) and twisting
1- make some thing to catch the can from both sides
2- then as what you first tried do it the same way, but with ading some very fast motor to spin the can while crushing
by that you get tow forces acting, the pushing and the spining
just to check how effecitvive this way is
try it by your hand, twist a can you'll find it crushing by it self, then stop twisting and crush, it will be so easy, and crush to a smaller size
also another solution
aply the presure with a slope
the orginal idea was
--|can|---engine
but to aply like that
--\can\--engine
it will be better,
also another idea
try a vibrator engine with the solenoid
the thing is to apply force which are parallel to the can sides, but to do it with a slope,
to proof what i said: try easly standing on a can trying to be straight, now try to move yourself front and back or right and left
at first the can will not crash, after you move it will
