Vehicle Cleaning TRIZ Cases

Air guide sections on a wiper arm redirect airflow to increase pressing force, resolving structural height constraints at high speeds.

Elastic side jaws on wiper blade end caps hold spring rails via molded engagement lugs, reducing material stress during assembly.

Segmenting locking and retaining functions into a single sliding element prevents flexible flap breakage during wiper blade attachment.

Variable blade speed and reduced ejection amount prevent centrifugal splatter into the upper windshield, protecting image capturing devices.

A self-adaptive wiper control system adjusts trigger thresholds and wiping speeds based on detected manual driver inputs.

Rear top clip member covers hook arm to reduce vibrations and noise while maintaining strong binding force in wiper blade adapter assemblies.

A wiper arm connector uses a resilient engaging portion to secure the blade assembly without rotating the entire unit.

A wiper arm hose guide forms a coupling element to attach auxiliary nozzle units without extra hardware.

A sealed windshield wiper structure uses a thermoplastic vulcanization cover to isolate the metal elastic sheet from external moisture.

A wiper adapter element uses a spring-loaded detent connection to release the wiper arm from the holding element for manual removal.

Engraved cavities in the main layer expose secondary pigment layers, solving fading issues from water and dirt exposure.

A cast fixing device for wiper arms uses securing elements to lock bearing bushes and retaining pins in place within dedicated receptacles.

Asymmetric spoiler design on semi-rigid wiper blades optimizes aerodynamic lift while reducing drag, lowering motor consumption and preventing detachment.

Laminated composite plates with viscoelastic layers reduce vibration and noise transmission in windscreen wiper geared motors, enhancing acoustic insulation.

A universal windshield wiper connector integrates a cantilever locking tab to secure side-saddle arms.

Rotating the transparent cover against a stationary wiping member cleans the lens, preventing rain or dust from degrading imaging quality.

Merging separate lines into one common bus reduces pipe count and assembly complexity for autonomous vehicle sensor cleaning.

Resilient latching means on a wiper blade limit pivoting movement to prevent unintended detachment and provide audible assembly feedback.

A vehicle window cleaning apparatus uses a suction pump and fluid tight conduit to extract water from the glass surface.

Resilient tongue with protrusions snaps into oscillating arm holes, eliminating separate joint parts and reducing device complexity.

Replaceable adaptor connects various wiper main arms to one support frame, eliminating material waste from dedicated frames.

A tapered channel in the wiper end piece grips the scraper heel via elastic deformation, preventing tearing during insertion and enabling easy replacement.

A wiper blade adapter uses a peripheral belt to surround the locking pin and secure the connection.
