Vaporware: Wiper Lift

There are a number of times when a piece of something (leaf, pine needle, ice, etc.) will get stuck under the windshield wiper and cause it to not stay in contact with the window leaving streaks. If a small ramp shaped lift were made at the very bottom of the stroke of the wiper then anything caught under the blade would have a brief moment to get free on each wipe or when the wiper is turned off. This would also allow for water build up at the bottom of the window to get to the upper side of the blade and get pushed off the top of the window on the next wipe.

The lift does not need to be a great distance.

The rubber not being in contact with the window when not in use should also prolong the life of the blade and help keep it from warping in extreme weather.
