Vehicle Cleaning TRIZ Cases

A narrowed adapter hinge with inclined and guide surfaces cuts mounting force and stress, preventing end cap breakage during wiper assembly.

A yoke-mounted pivoting end cap adds rotational and translational freedom, helping a faired wiper follow windshield curvature without assembly stress.

Separate air and washer flow paths merge at the nozzle tip to maintain LiDAR cleaning when cold fluid viscosity lowers discharge pressure.

Separate air and washer-fluid paths discharge together to keep camera lenses clean in cold conditions while using less washer fluid.

An external pivot and shear-pin wiper mount lets rotating disc dryers be adjusted and serviced outside the shell, reducing damage and downtime.

Position-timed liquid spray and air puffs clean rotating sensor surfaces while reducing overspray, waste, and signal blockage.

Elastic arms with bumps engage restricting slots to stop wiper driving arm loosening and keep the connection stable over time.

Position-controlled air nozzles on the wiper arm redirect washer fluid away from A-pillars to reduce runoff and preserve visibility.

A timed delay between washer spray and wiper motion helps thaw a frozen windshield faster while reducing blade damage.

A longitudinal stop limits wiper arm insertion to protect the locking button and enable secure blade assembly and removal.

A sliding, pivoting telescopic wiper extends reach and maintains blade pressure to clean curved windshields and upper corners more completely.

A rail-guided wiper with tilting and length adjustment reaches windshield corners and keeps stable blade angle and pressure on curved glass.

When the driver-side wiper motor fails, the passenger-side blade expands its sweep to preserve visibility without blade interference.
