The wiper blades has seen numerous model variations since its design and availability in nineteen fifteen to its present day form exemplared by state of the art silicone replacement wiper blades. The backgorund of one such ancestor is that of an engineer called Rob Kearns, who was responsible for the creation of the intermittent wipers technology you take for granted whenever it pisses down. All technology has an beginning and a back story but it’s also something so all-pervading that we take several of these contemporary day amazements for granted. Just take a second to adjudicate something as everyday as an intermittent wiper blade apparatus and how truly astonishing this seemingly simple academic discipline is.
The whole contrivance is driven by an infinitesimal energy field called electricity composed of many sub atomic particles which can some how be converted into mechanical force to drive the replacement wiper blades. Just how this odd invisible particle translates to mechanical force, how is energy held within a flow of electrons. The entire wiper blades 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 bracketed from the battery to the wipers mechanism is like a hiking trail for the electrons in the outer shell which are held rather loosely are accessible to move up and down the wire like a assemblage of displaced people. When an electric force is employed 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 employing an electric motor. The electric motor is able to propel the replacement wiper blades by using electricity to generate 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 try to line up, then by repeatedly altering the magnetic field by changing the agency of electrons through the wire you get rotational movement. This motion is then harnessed and used to propel the wipers mechanism, easy. The inventor of the intermittent wiper blades mechanism Rob Kearns used this stuff 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 attempting 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 forced 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 cultured and rich life since those early crazy days.
