The wiper blade has seen major adjustment over the duration of its quick evolution; to date the everyday design has reached a pinnacle in automotive design by utilising a substance called silicone to improve performance characteristics. The wiper blade is the output of many human minds thinking together on a single over arching goal that is to maintain a clear wind screen so drivers have an clear view of their destination. This goal is relatively basic but none the less contributes massively to road safety and therefore is accountable for reducing death and serious injury by a huge factor. Indeed the common wiper blade is commonly taken for granted but without the safety data on the road would be truly appalling and in the opinion of this observer the wiper blade has contributed just as much to safety culture as the air bag or the seat belt. In fact, it was an accidental meeting between a car and a bicycle at the start of the twentieth century which prompted a rich industrialist to start manufacturing wiper blades in huge quantities such was his grief at having caused bodily harm to an unwary life.
According to the government body responsible for cataloguing serious road accidents the major cause of which is often down to poor visibility, in fact so much so that having faulty windscreen wipers is adequate grounds for quiting the Ministry of Transports car performance test. The windscreen wipers is a truly remarkable example of design, take a moment to consider just how special it truly is. Think for a second to adjudge how magical electricity is that powers the windscreen wipers, this being composed of countless tiny particles which are invisible to the bare eye yet are responsible for powering our entire civilisation. These little points of charge flow through metal due to the free electrons present in their chemical structure that is why they are called conductors. The windscreen wipers motion is driven by the changing of this flow of invisible sub atomic particles into motion energy by a process called electromagnetic induction, the electricity creates an magnetic field which can be harnessed to produce kinetic energy driving the wipers though its range of motion.
The electric motor is the design marvel most responsible for the replacement wiper blades huge success, in the past a device called a vacuum motor was utilised but this had the unfortunate side effect of slowing down in relative to how fast the motor was revving. Therefore at high pace the replacement wiper blades would slow to a walk and at low speeds they would go like the clappers. With the advent of the electric motor the replacement wiper blades was able to become more flexible and soon developed different speed settings to suit the prevailing weather conditions. The inventor of the intermittent replacement wiper blades mechanism was a guy called Mr Kearns who got the thought after the regular motion of the replacement wiper blades began to irritate his poor vision. Later a bitter protracted legal battle would ensue as Mr Kearns fought for his patent rights as the large car companies proceeded to steal his great idea.
