SPEED WIPER BLADE(1960s to 1970s)
Appearance in 1968, it used wire to help with wind resistance. This solved the problem of windshield wiper blades being pulled away the window in high winds. Mazda Luce ( Cosmo) was the first vehicle to use speed blades.
Slim Wiper Blade (1970s to 1980s)
It was developed in 1976. With the slim wiper blade came more wind resistance and it was improved to help reduce glare. The coloring also went from silver to the standard black of modern times.
Tournament Wiper Blade ( From 1980s)
Introduced after 1980, it showed significant change which handled better at high speed. It was made to apply equal pressure to all parts of the windshield to avoid streaking . Wipers today are based around this design.

I don't see what this has to do with anything??

1.Windshield Wiper Blade

The wipers combine two mechanical technologies to perform their task:
A combination electric motor and worm gear reduction provides power to the wipers.
A neat linkage converts the rotational output of the motor into the back-and-forth motion of the wipers.

2.Wiper DC Motor and Gear Reduction

It takes a lot of force to accelerate the wiper blades back and forth across the windshield so quickly. In order to generate this type of force, a worm gear is used on the output of a small electric motor.
The worm gear reduction can multiply the torque of the motor by about 50 times, while slowing the output speed of the electric motor by 50 times as well. The output of the gear reduction operates a linkage that moves the wipers back and forth.
Inside the motor/gear assembly is an electronic circuit that senses when the wipers are in their down position. The circuit maintains power to the wipers until they are parked at the bottom of the windshield, then cuts the power to the motor. This circuit also parks the wipers between wipes when they are on their intermittent setting.

3.Linkage and Arm
A short cam is attached to the output shaft of the gear reduction. This cam spins around as the wiper motor turns. The cam is connected to a long rod; as the cam spins, it moves the rod back and forth. The long rod is connected to a short rod that actuates the wiper blade on the driver's side. Another long rod transmits the force from the driver-side to the passenger-side wiper blade.
Now let's talk about some details of the wiper blades.
