Vehicle Cleaning TRIZ Cases

An embedded motor drives linear blade motion on glazed surfaces, cutting wiper bulk and preserving a clear field for detection modules.

An elastic hollow check valve with a pressure-opened slit simplifies washer nozzle assembly and shrinks the wiper blade washer unit.

A constant-width rod and dual retention channel reduce play, corrosion, and force loss in flat-blade wiper arm connections.

A recessed rear wiper receptacle hides the blade when parked while adding drainage, heating, and precise position sensing for snow and water control.

A rear fascia door relocates the washer fluid reservoir out of the hood area while preserving refill access and rear fascia structural integrity.

Frequency-tuned polyurethane blade rubber balances curved-surface followability with stable contact and stronger dirt scraping.

A spring-loaded wiper uses sensor housing rotation to clear debris and moisture while maintaining contact without damaging the housing surface.

Adjustable wiper pressure cleans camera and LiDAR sensor surfaces effectively while limiting blade wear, noise, and motor load.

Multiple connector claws hold the wiper spoiler in the height direction to stop detachment and keep the blade assembly stable.

Short conduits, valve control, and timed pressure pulses cut vehicle sensor cleaning fluid use while maintaining effective coverage.

Cleaning nozzles are selectively stopped in overlapping sensor regions, while non-cleaned sensor data is prioritized to preserve sensing accuracy.

A rib-and-window retention structure strengthens the adapter-to-mount connection, preventing wiper disassembly under heavy lateral, torsional, ice, and wash loads.

A pivoting locking cap and universal coupling groove help one wiper adapter fit varied arm shapes while keeping blade attachment stable and easy to release.

Surroundings-aware control delays or modifies vehicle sensor cleaning when pedestrians, cyclists, or sensitive objects are nearby.

Liquid and air jets with a deflection orifice keep self-driving car sensors clear while preventing air-jet contamination in a compact layout.

Driver gaze and precipitation sensing trigger wipers only when visibility is needed, reducing idle energy use and splash on nearby people or vehicles.

Clamping the wiper lip before tip cutting prevents elastic deformation, producing a flatter cut and restoring stable wiping performance.

A clamped and pre-pressed lip enables precise wiper blade rubber recutting, preventing cut-surface tilt and restoring uniform wiping.

An integrated top-cover release element lets engineers replace a wiper blade without removing the cover, while preserving aerodynamics and appearance.

A single pressurized tank uses shared gas and washing liquid delivery to clean vehicle sensors with less hardware, cost, and complexity.

Adaptive heater control uses outside temperature and vehicle speed to clear snow from a ranging window while reducing power use.

Compressed air drives venturi mixing and liquid delivery for vehicle sensor cleaning, removing shut-off valves and extra pumps.

Heated water vapor is pumped through the interior wiper to loosen fog and dust on the windshield, improving visibility in humid driving conditions.

Dual elastic fasteners let a wiper blade detach easily from nozzle-integrated arms while staying securely fixed during wiping.

Mounting the washer nozzle on the wiper arm shortens the spray path, clears fluid faster, and reduces windshield washer use.

Independently controlled air nozzles target contaminated headlamp lens zones, improving optical sensor visibility without running the full cleaner.

A rotatable locking adapter secures the wiper blade to varied arm shapes, improving seating stability, replacement ease, and noise control.

A coaxial rotating connector keeps power flowing through wiper articulation, enabling blade heating to melt ice without scraping the glass.

Opposed abutment surfaces in the arm head and shank stabilize the wiper linkage, cutting rattling noise and improving wiping performance.

A single-sided bent middle blade balances wiping pressure to improve cleaning while reducing wiper noise, wear, and jumping.

A segmented cam profile extends contact signal duration, making wiper park position detection more reliable for vehicle drive systems.
