The origin of windshield wipers can be traced back to the early stages of automobile development. Here is a clear and summarized account of their history:
Early Stages:
From the invention of the first modern automobile in 1885 until the early 20th century, cars did not have windshield wipers. Drivers had to drive with the windows open in the rain, often resulting in accidents due to poor visibility.
Initial Concept:
In 1876, an American woman named Mary Anderson observed that drivers had to frequently extend their arms to wipe the windshield in rain and snow, posing significant safety risks. She conceived an innovative design: installing a rubber blade on the windshield that could be manually operated to clear rain and snow. This idea is considered the prototype of the windshield wiper.
Appearance of Manual Wipers:
In 1903, French engineer J.P.J. De La Motte installed a manual windshield wiper on a windshield, attracting the attention of car manufacturers.
In 1917, American J.R. Oishei, after experiencing a near accident while driving in a rainstorm in Buffalo, New York, invented a manual wiper with a metal arm and a rubber strip to prevent similar incidents.
Invention of Electrically Driven Wipers:
Due to the inconvenience of operating manual wipers while driving, Oishei further developed the idea and successfully created an electrically driven wiper system in 1917. This marked the beginning of the modern windshield wiper.
Birth of Intermittent Wipers:
In the 1960s, American inventor Bob Kearns, who lost vision in his left eye from a champagne cork, found it challenging to see clearly while driving in the rain. This motivated him to invent intermittent wipers, which he successfully developed in 1963.
Development of Modern Wipers:
With the continuous evolution and innovation in automotive technology, windshield wipers have also undergone constant upgrades. Modern wipers are no longer manually operated but use electric or pneumatic power to function automatically. Advanced systems can even detect the amount and density of rain, adjusting the wiper speed accordingly, greatly enhancing driving safety and convenience.
Conclusion:
The history of windshield wipers shows their evolution from manual operation to electric power and finally to intelligent adjustment. This development not only reflects technological innovation but also demonstrates humanity's ongoing pursuit of driving safety.
