Design and function of wipers: front wipers vs. rear wipers

Among the many parts of a car, wipers are undoubtedly one of the key devices to ensure driving safety. Their main function is to remove rain, dust and other dirt from the windshield to keep the driver's vision clear. According to the installation position and the shape of the windshield, wipers are divided into front wipers and rear wipers, each with its own characteristics in design and use.

Front wipers: the wisdom of fan-shaped design
Front wipers, as the name suggests, are installed on the front windshield of the vehicle. The choice of this position is not accidental, but based on careful consideration of driving safety. The front windshield is the main window for the driver to observe the road conditions ahead, so its cleanliness is crucial. The front wiper usually adopts a fan-shaped design. This shape is not designed casually, but to better fit the curved surface of the front windshield.

The fan-shaped wiper can more effectively cover the entire surface of the windshield, ensuring that every inch is swept evenly and thoroughly. In addition, the size of the front wiper is relatively long, which is to adapt to the larger area of ​​the front windshield. Longer wipers can clear rain faster and reduce the blur in the driver's field of vision, thus improving driving safety.

Rear wiper: Practical rectangular design
Compared with the front wiper, the rear wiper is simpler and more practical. It is usually installed on the rear windshield of the vehicle, and the choice of this location is also based on driving safety considerations. Although the rear windshield is not the driver's main observation window during driving, its cleanliness is also crucial when reversing, observing the rear vehicle or merging.

The rear wiper often adopts a rectangular design because the shape of the rear windshield is relatively flat. The rectangular wiper can better adapt to this shape and ensure the cleaning effect. In addition, the size of the rear wiper is relatively short, mainly because it is mainly responsible for cleaning the local area where the rearview mirror is located. Although the cleaning area is small, this design is sufficient to meet the cleaning needs of the rear windshield.

The front wiper and the rear wiper have their own characteristics in design and use, but they both contribute to driving safety. The fan-shaped front wiper can more effectively cover the entire surface of the front windshield, ensuring a clear view for the driver; while the rectangular rear wiper can accurately clean the dirt on the rear windshield, ensuring a clear view for the driver when reversing or observing the rear.

In daily use, we should regularly check the wear of the wipers and replace damaged wiper blades in time. In addition, in severe weather conditions, such as heavy rain or sandstorms, the frequency of using the wipers should be increased to ensure the cleanliness of the windshield. Only in this way can we make better use of the function of the wipers and improve driving safety.
