Towing Devices TRIZ Cases

A removable support bar lets heavy ball mounts hang vertically, saving retail space while making size and variation differences easier to see.

A lever-driven transmission retracts the coupling pin by pulling instead of pushing, making drawbar coupling easier and more ergonomic.

An extendable lever built into the handwheel cuts locking force, improves intuitive use, and blocks accidental trailer coupling actuation.

An ECU adapts knob steering limits to each trailer backing maneuver, making reverse control more accurate and easier for one driver.

A pivoting, detachable tow hook assembly preserves towing strength while reducing front-end collision damage to the vehicle and barrier.

Invalid speed or ignition signals can trigger unsafe coupling-arm movement, so this control unit validates vehicle status before actuation.

A camera tracks trailer features in the image to calculate relative position, helping drivers maneuver turns and reversals with fewer collisions.

Adjustable delivery housings, turntables, and rail sensors automate RV storage and retrieval while reducing damage risk and wasted space.

A load-measuring hitch adjusts spring bar tilt and preload to set tongue weight quickly and reduce sway and tire overload.

Magnetic field sensing in tow coupling pins measures load direction and force without strain-gauge weakening, enabling alerts and stability control.

An incomplete gear and locking layout lets an electric trailer hitch retract cleanly while holding stable extended and retracted positions.

A rotating hitch arm uses a swivel and lock mechanism to keep towing stable while opening tailgates, trunks, or cargo doors.

Electromagnetic force keeps a stable gap in a vehicle joint coupler, reducing impact and slipping during turning, acceleration, and braking.

Blocking surfaces and angularly spaced rotary locking units hold the actuating body only in intended release positions, reducing noise and complexity.

Offset brackets remove transverse cross members so under-bed hitches fit varied truck frames with easier installation, access, and lower weight.

A rotating base plate and shackle self-align with load direction, spreading force for safer side pulling on recovery vehicles.

Multi-sensor sway prediction combines hinge angle, cameras, radar, and IMUs to warn drivers early and apply staged trailer stability control.

A flexible cable grommet adds space for switches or speakers while the hard housing protects trailer coupling electronics from dust and moisture.

A rotating receiver piece and composite bearing assembly expand hitch articulation to reduce towing stress and failure on uneven terrain.

A Hall sensor detects active and inactive lock states in a trailer coupling, giving unambiguous rest and operating position signals.

Adjustable fixing surfaces compensate for tolerance and wear, keeping a swivel trailer coupling securely locked in use and non-use positions.

By integrating sensors, drive motor, and pivot control into one housing, the coupling cuts mounting complexity and improves fault resistance.

A single camera tracks two trailer image regions to determine relative orientation accurately without multi-sensor triangulation.

A sensor-triggered locking mechanism retracts the tow hook before impact to reduce damage to vehicle components and barriers.
