Ferrari has filed a new windshield wiper patent that completely rethinks how the system clears rain from the glass, replacing the conventional back-and-forth motion with a sliding design. The unusual concept could reduce weight and costs while also offering Ferrari new design and aerodynamic possibilities.
Ferrari Wants to Change How Windshield Wipers Work
The conventional windshield wiper uses a motor and mechanical linkage to move the wiper arm back and forth across the glass. Ferrari’s latest patent proposes eliminating that rotational movement altogether.
Instead, the patented system would use an electromagnetic linear actuator mounted in a track. The wiper would remain pointed straight up as it slides from side to side across the windshield rather than sweeping across the glass in a traditional arc.
The system would cover at least half of the windshield, with Ferrari outlining two possible configurations for completing the wiping process.
Two Different Sliding Wiper Designs
In the first configuration, the track would extend across roughly half of the windshield. Once the wiper reaches the end of the track, a motor would move the blade like a conventional wiper to clear the remaining portion of the glass. The blade would then slide back and repeat the process.
The second configuration would use a track extending across the entire windshield. In that setup, the wiper would simply slide back and forth across the glass.
Why Ferrari Is Exploring the New Wiper System
Despite the added track, flexible wiring and the possibility of a chain drive, Ferrari’s patent describes potential advantages in both weight and cost. The inventors say the system could have small dimensions and low weight while clearing a “particularly wide” area of the windshield.
The design could also reduce costs when adapting the system to different vehicles. According to the patent, Ferrari would only need to change the track and the height of the blade for a new car.
The system would also work identically for left- and right-drive vehicles, whereas current systems need to be adapted for both configurations.
Ferrari’s Wiper Could Also Affect Aerodynamics
The patented design could offer an aerodynamic benefit as well. Ferrari says the system would allow the hood to run directly up to the windshield, improving the aerodynamic transition between the two areas.
The automaker also suggests that the arrangement could improve the wiper’s appearance. However, a wiper parked alongside the A-pillar would remain visible, even though Ferrari says the components would “become one single assembly to the human eye.”
Ferrari’s latest patent therefore proposes a fundamentally different approach to windshield wiping, combining a sliding mechanism with potential weight, cost, aerodynamic and design benefits.
