Wovel Photos – bet that phrase will send corporate web proxies into paroxysms of denial 
Neat combo of wheel (movement and leverage) and shovel. Not sure though that you wouldn’t put your back out trying energetic flips, nor that having 10kg of snow flipped skywards is going to help the clearing effort.
As a suggested upgrade, why not have either a snowploug front end (just run along the path, clearing a route) or have a twist/elliptical pivot so that the shovel flicks to one side as its raised?
No royalties required for these design “improvements”
