Towing Devices TRIZ Cases
- Pivoting Trailer Hitch for Misaligned Coupler Alignment
A height-adjustable pivoting hitch uses swivel and horizontal pivot assemblies to align misaligned trailer couplers and lock securely.
- Universal Trailer Coupling Lock With Interchangeable Hitch Adapters
A universal lock body with nested hitch adapters secures many trailer coupler types while cutting SKU count, cost, and fit confusion.
- Vehicle Hitch Plunger Dampener for Debris-Resistant Noise Control
A lever-driven plunger presses on the hitch attachment arm to cut rattle and wear while resisting debris during off-road use.
- Pivoting Hitch Adapter With Multi-Point Cargo Securement
Multiple anchor points and a pivoting latch plate let one hitch adapter secure varied cargo quickly across different hitch sizes.
- Foldable Ball Hitch Indexing for Stowed and Deployed Positions
Indexing holes, channels, and pins let the hitch plate pivot and lock between stowed and deployed positions without removing the hitch.
- Single-Motion Trailer Hitch Locking for Full-Ball Engagement
A slide plate and lever lock the hitch ball on all sides in one motion, improving trailer coupling stability, security, and ease of use.
- Coupling Pin Torque Sensing for Accurate Towing Force Detection
Torque sensors on coupling pins separate vertical and horizontal towing forces to avoid distortion and keep force readings accurate on slopes.
- Telescoping Trailer Coupler for Adjustable Tongue Height
Nested legs, aligned bolt holes, and nut holders let a trailer coupler lock at different tongue heights for secure vehicle hitch matching.
- Trailer Hitch Hardening for Load and Wear Resistance
Localized hard support elements reinforce high-load hitch regions, improving wear resistance while keeping the main body ductile.
- Adjustable Trailer Coupler With Height-Locking Quick Mount
A height-locking connecting base and elastic latch simplify trailer coupler mounting across vehicle heights while improving secure engagement.
- Magnetic AGV Coupler for Stable Utility Cart Towing
Magnetic coupling helps AGVs tow utility carts securely, using rotational alignment and sensor-triggered disengagement to improve safety.
- Tow Bar With Integrated Wiring for Flat Towing EVs
Integrated mechanical joints and a wiring harness enable flat towing of EVs while cutting trailer cost and supporting brake and signal control.
- Adjustable Trailer Hitch Restrictor Arms for Jackknife Prevention
Adjustable arms and stop points limit trailer hitch swivel during turns, helping prevent jackknifing across different trailer sizes.
- Trailer Coupling Cladding for Protected Ball Neck Styling
A separate cladding covers trailer coupling support spaces to improve appearance, resist water and stone chips, and house sensors or connectors.
- Trailer Cord Retention Mount for Clearance Without Hanging Damage
A rotatable mount coils and secures a trailer electrical cord to preserve towing clearance while preventing hanging damage and pest access.
- Crash Box Reinforcement for Stronger Lashing Hook Support
A crosswise reinforcing member inside the spot-welded crash box boosts lashing hook strength while avoiding thicker steel and higher welding cost.
