Vehicle Cleaning TRIZ Cases

A wiper blade end cap uses a movable spoiler element to deflect airflow and generate pressing force.

A sliding collar mechanism secures the washer tank to its support, eliminating complex assembly steps and reducing connection failure risks.

A silicone rubber wiper blade coating uses boron nitride and graphite solid lubricants to enhance surface friction properties.

A vehicle window cleaning foam generator adjusts air flow to optimize foam density for effective windshield washing.

Merging the reservoir and emitter eliminates complex fluid connections, reducing construction complexity while maintaining cleaning reliability.

A universal windshield wiper connector accommodates varying pin lengths and locking mechanisms across multiple arm types.

An offset longitudinal web guides the adapter laterally, absorbing high torques while maintaining minimal play across multiple wiper arm types.

Resilient legs in the U-shaped connector block lateral bending during wiping for stability, then release to allow easy disconnection for maintenance.

A vehicle wiper control device moves blades to a storage position when motor load exceeds a threshold.

A windscreen wiper blade uses a resilient bottom to move the wiping element perpendicular to the glass surface under pressure from a carrier strip.

A continuous-rotation motor drives a wiper at variable speeds to spray de-icing liquid onto vehicle windows.

Offset detent means on the wiper blade adapter engage corresponding spring rail cut-outs to distribute fastening forces and prevent detachment during operation.

A plastic protective cover with flexible arms snaps onto the wiper arm to seal the shaft connection interface.

A hinged adapter joins wiper drive arm sections via a U-shaped front and rear part assembly.

Segmented abrasive channels mimic blade deformation to uniformly resurface all three sides, preventing overcutting on varying thicknesses.

Rectilinear slot design simplifies fitting by inverting conventional elbow-shaped geometry.

Spring-loaded interference fingers in a U-shaped joint part secure various wiper arms, eliminating multiple connecting devices and lowering manufacturing costs.

A spring arrangement presses the wiper arm against a curved windshield, resolving reliability and complexity contradictions.

Asymmetric connecting device with protrusions and guiding tongue prevents reverse mounting to maintain wiping performance.

Dual pour-point plasticizers increase viscoelastic damping in chloroprene rubber, reducing friction noise while maintaining low-temperature elasticity.

A detachable nozzle engages a U-shaped adapter on the wiper arm to follow its oscillatory motion.

A liquid spraying device mounts on a wiper blade tip using an integrated housing and lugs for secure fixation.

Resistive heating wires in wiper blade accessories prevent washing liquid freezing and structural stiffening at low temperatures.

A heating device routes electrical connections through a stiffening element's central hole to distribute heat along the wiper blade.
