Intermittent Wiper Blade Science Commonly In Use.

The wiper blade has seen many style variations since its invention and employment in nineteen fifteen to its current day form exemplified by state of the art silicone replacement wiper blades. The story of one such ancestor is that of an designer called Rob Kearns, who was responsible for the creation of the intermittent wipers appliance you take for granted whenever it pours. All technology has an beginning and a back story but it’s also something so all-present that we take several of these modern day miracles for granted. Just take a moment to analyze something as common as an intermittent wiper blade mechanism and how truly breath taking this seemingly basic academic discipline is.

The whole contraption is driven by an infinitesimal energy field called electricity compounding of numerous sub atomic particles which can some how be translated into mechanical force to propel the replacement wiper blades. Just how this strange invisible particle translates to mechanical force, how is energy held within a flow of electrons. The entire wiper blade apparatus is in effect driven by a flow of electric charge along a copper wire which carries electrons which carry the charge. This astonishing feat can be described in terms of how the wire connected from the battery to the wipers mechanism is like a footpath for the electrons in the outer shell which are fastened rather loosely are abandoned to move up and down the wire like a crowd of displaced people. When an electric force is set to either end the free electrons all rush toward the positive end in the direction of the electric force. These intrepid electrons can be then changed into mechanical force to drive the replacement wiper blades by using an electric motor. The electric motor is able to propel the replacement wiper blades by using electricity to produce a magnetic field, coiling wire around a metal spike will bear an electro magnet.

Place the electro magnet inside another magnet and the two poles will attempt to line up, then by repeatedly flipping the magnetic field by changing the direction of electrons through the wire you get rotational movement. This activity is then harnessed and used to drive the wipers mechanism, easy. The inventor of the intermittent wiper blade mechanism Rob Kearns used this energy to create his new technology, legend has it that he got his bug idea on his wedding day when champagne cork fired into his eye which creepingly started to go blind, then years later the constant motion of the replacement wiper blades started to irritate his poor vision and so the idea was born to model the motion of the replacement wiper blades like the blinking of a human eye. After trying unsuccessfully to generate interest in his idea by the big car manufacturers, they then went on to produce their own versions for which they were promptly sued. Ford lost their trial and was advised to pay ten million dollars to the rightful inventor; next to fall was Chrysler who was told to pay nearly twenty millions in costs. And rightfully so, justice was served and big business was unable to screw over the little guy, paying dearly for their greed and hubris. The wipers has gone on to live a interesting and rich life since those early crazy days.
