Due to the ever present requirement for drag reduction, the windscreens of many cars are becoming ever more inclined. This presents the problem of requiring larger and larger legal swept areas; this in turn requires a longer blade and a longer arm with a more powerful motor driving it but in a smaller space and with a lower overall weight.
As the height and width of windscreens increase, the length of a driver-side wiper becomes longer than the passenger-side blade to provide a wider view for the driver.
Over the past few years, the so-called flat wiper blade market has blossomed. Flat blades have a lower profile than conventional wiper blades, making them more aesthetically pleasing as well as giving them better wind resistance, especially at high speeds. In addition, the fact that flat wiper blades don't clog with ice and snow causing them to bend and break also leads to fewer warranty claims for manufacturers.
The flat blade market is booming in India as rest of the world. Numak™ is the pioneers in bringing flat blade wipers here.
