Towing Devices TRIZ Cases

A movable tow bar assembly uses a drive motor to translate the towing attachment along an elongate frame for precise trailer control.

A trailer hitch coupling system uses load and electrical usage sensors to detect connection states.

A vehicle mirror system automatically extends side view mirrors to a trailering position using detection devices and a controller.

An offset pivot bar inside an elongate opening secures trailer connections, eliminating cotter pins and reducing component loss.

A tow hitch assembly uses a compression spring and visual indicator to verify trailer tongue weight.

A bifurcated guide system directs a slidable pivot along diverging channels to prevent over-pivoting and reduce friction during tight turns.

A pivotally coupled guide element dynamically adjusts its angle to correct significant misalignment between trailer and towing vehicle hitches.

A hitch-mounted dolly pivots its support surface between ramp, loading, and vertical transport positions.

A towing assembly uses a diffuser strap to absorb kinetic energy from a broken recovery strap.

Segmented clamp assemblies enable rapid one-handed connection, eliminating complex screw pin threading and reducing installation time.

A dual-reacting hitch pin adapter uses a single load sensor to determine trailer weight across varied vehicle configurations.

A hydraulic hitch lift system raises a tow ball vertically to engage vehicle couplers without manual intervention.

Sensor fusion guides the hitch ball toward the coupler, preventing collision risks from manual alignment overshoot.

A motorized lead screw mechanism extends and retracts the trailer hitch, eliminating manual labor.

A spring-loaded safety arm prevents unintended drawbar release by maintaining a self-locking angle with the stop surface under extreme vibration.

A tow-hook arrangement uses a vertical locking element within a guide to secure the towing position on mobile machinery.

Segmented bracket members with adjustable mounting holes resolve frame height variability, ensuring even load distribution across towing vehicle axles.

An exterior-mounted trailer hitch control unit minimizes internal cable routing complexity by utilizing a dedicated protective housing with sealed connections.

Multi-joint elevated hitch resolves terrain adaptability trade-offs by enabling independent joint movement for minimal turning radius.

A removable securing chain attachment assembly features a rotatable body and pivoting securement member.

A monobar hitch system uses a single spring and offset pivot axis to distribute tongue weight across towing vehicle wheels.

A coupler lock housing covers the handwheel and socket while an aperture allows visual confirmation of the threaded member.

A towing hitch assembly integrates ball and clevis couplings on a single mounting plate secured to a drawbar via removable brackets.

Nested tubular members and a rotatable handle resolve manufacturing complexity while improving ergonomic operation.

A movable gooseneck hitch assembly transitions between extended and retracted positions using a sleeve and locking mechanism.

Selective hardening of a steel sheet blank creates variable strength zones in a trailer coupling carrier, resolving complexity and weight trade-offs.

Telescoping connector sections adjust length to reduce storage volume while segmented locking layers prevent theft without complicating coupling operations.

A telescoping safety chain tool with a handle and coupling mechanism enables remote attachment of trailer chains from outside the truck bed.

Merging the decorative sign with the ball mount eliminates removal steps and prevents loss while maintaining aesthetic continuity during towing.

Adjustable friction clamp restricts spindle post rotation to stabilize trailer sway during towing.

A pivotally mounted towing hook support rotates with a tilting vehicle ramp, eliminating mechanical interference and preserving full ramp usability.

A trailer hitch adaptor uses a stop assembly to guide a connecting bar into a cradle opening.

A movable dolly tongue receptacle operates a switch to extend a locking pin, preventing misalignment and unintended activation during automated coupling.

An integral rib structure on the base body increases rigidity and energy absorption while reducing manufacturing complexity.

Diagonally displaced tubular elements press against receiver walls to reduce wobble and instability in trailer hitch connections.
