Removable External Protective Coverings TRIZ Cases

A protective cover on the hopper side wall prevents paving material from entering the gap between the discharge flap and hopper, avoiding jamming.

A mirror protector uses an indent and notches to shield a vehicle wing mirror while allowing indicator light transmission.

Nesting holding arms reduce space in non-working positions while preventing mechanical stress on the tarpaulin during deployment.

Automated motorized winding overcomes manual crank difficulty while protecting the drive mechanism from impact damage.

A trailer bumper block assembly uses a spring-mounted fastener to maintain recessed positioning during compression cycles.

Pneumatic inflation expands flexible panels to tension the covering sheet, resolving the trade-off between weather protection and ease of operation.

Mating magnets on vertical strips automatically reattach after outward pressure, reducing ingress time while maintaining secure closure.

A biasing element maintains tension on a rolling rod to prevent folds that cause mechanical stress and reduce tarpaulin lifespan.

Variable fixing devices anchor roller blind guide rails to vehicle windows at discrete positions, preventing fabric sagging changes that obstruct the view.

Hingeable housing stores the cover on a rotatable roller, resolving bulkiness and placement difficulty.

Removable thermoformed ABS plates secured by neodymium magnets shield off-road vehicle body panels from impacts while preserving urban aesthetics.

A foldable waterproof bag uses a segmented lower cuboid part and upper cover to ensure watertightness and floatability for stored items.

Curved shade cover supported by rods shields RV roofs from UV degradation, resisting wind displacement while maintaining elevated cooling positions.

A rotatable frame vehicle cover system unfolds automatically to shield the car from environmental elements.

A foam body connects a waterproof plane to the caravan roof, providing immediate hail protection without manual deployment.

A rack-mounted weather shield uses folding fans to create a protected space along vehicle sides.

An electric motor drives a cable winch to move trolleys along a track, replacing manual cranking for easier tarp operation.

Removable magnetic platform assembly shields pickup truck cabs from impact damage during hauling operations.

Telescoping control arms replace manual climbing to improve operator safety while maintaining simple mechanical construction.

A retractable vehicle cover system uses a cord reel to wind the fabric into a container, replacing manual stuffing that wastes time and labor.

Resilient clips bias a vehicle cover body toward the frame for secure attachment.

A tonneau cover side rail incorporates a ridge structure to guide the flexible cover during closure.

Spring-loaded roller retracts vehicle cover into bumper housing, eliminating manual folding and reducing user exposure to contaminants.

Segmented panels slide into roof enclosures to resolve weather protection versus deployment speed trade-offs in open-air vehicles.

Pre-folded accordion lower panels compress storage volume while expanding to shield vehicles from hail and water ingress.

A door protection pad uses wedge-shaped stay tabs inserted between the window and weather stripping alongside a suction cup for secure attachment.

Segmented cover panels nest for storage while resisting hail impacts.

LIDAR sensors detect nearby objects and trigger pneumatic valves to expand accordion bellow strips, absorbing impact energy before it reaches the door panel.

Downward-extending pulling ropes and sticks lift a rectangular box cover from ground level, eliminating hazardous roof climbing during assembly.

A frangible breakaway connector links a radial arm assembly to a tarp roller, absorbing mechanical stress through controlled fracture.

Neodymium magnets in a flexible strip attach a protective device to vehicles without damaging the paint during installation or removal.

A universal elastic mirror cover prevents sliding and damage by adapting its fit across different vehicle types without custom molds.

A vehicle cover cloth zipper employs a flexible maneuvering element to uncouple the windshield portion, enabling one-sided operation in confined spaces.

Segmented bed rail covers reduce shipping costs and transit damage while maintaining a continuous aesthetic appearance through concealed seam design.
