Towing Devices TRIZ Cases

A floor-mounted adjustable hitch keeps the trailer tongue level in a garage, enabling stable ATV loading while reducing lift, gate drop, and injury risk.

An encapsulated tracking circuit inside the trailer wiring harness avoids retrofit installation, corrosion exposure, and visible tampering.

By lifting the front of the towed truck and keeping its rear wheels on the ground, this towing setup stays under height limits and avoids reverse-tow damage.

A movable engagement and locking structure lets the hitch handle heavy towing loads, road inclines, and vibration without unintended disassembly.

A rubber tow hitch bumper with reflective magnetic plates helps align the trailer ball and coupler while preventing attachment damage.

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

An adjustable spring arm replaces multiple tow-load bars while using friction pads and pin mounting to balance trailer weight and control sway.

A color-changing insertion prompt and turning plate help confirm full tractor hitch insertion quickly while reducing trial-and-error adjustment.

Corrected trailer-end and hitch-ball coordinates improve camera-based hitch angle calculation after world-coordinate transformation.

Positive-locking contours and clamped support bodies simplify trailer coupling mounting while improving force transfer and tilt resistance.

Camera-guided drive systems align the hitch arm and trailer coupler automatically, cutting manual ratcheting and hitching time in harsh conditions.

Adjustable aerofoil wings rotate to create downforce and lift that counter crosswinds, helping parked trailers resist rollover.

Sensor-driven wheel actuation counters crosswind and load-shift instability in towed vehicles to reduce sway and jackknifing.

Multi-sensor hinge, radar, camera, and IMU data predict trailer sway early, warn the driver, and trigger staged stability control.

An insertion aid shields the lubricant cap edge in a coupling socket, tolerates alignment variation, and reduces impact damage under high loads.

Expandable tubular sections press against the hitch receiver to secure varying fits and prevent towing vibration and oscillation.

A segmented hitch, shock assembly, and caster steering improve trailer backing control, stability, tire wear, and manufacturing efficiency.

A strut-based ball neck cuts trailer coupling mass while preserving stability and creating space for sensors and electrical connections.

A spring-reset pin lets trailer ball heads rotate and relock without disassembly, cutting adjustment time and preventing pin loss.

A tow hook retracts under lower impacts and detaches at higher loads, reducing collision damage while preserving towing strength.

Integrated locking blocks replace loose hitch pins, enabling fast towing setup, receiver fit adjustment, and theft-resistant retention.

A multi-size hitch ball attachment uses locking and quick-release pins to switch skid steer or forklift towing setups with less downtime.

A compliant two-leg vehicle tether uses prismatic joints and damping to stabilize platoons, reduce jack-knifing, and keep exact path following.

Inflatable billows position trailer lines for automatic truck-trailer connection, improving alignment reliability without manual intervention.

An adjustable threaded and pivoting trailer coupling fits different power-assisted vehicles while allowing vertical and rotational towing movement.

A rotating door plate and lock unit secure a wheel support member without lifting or chain locks, preventing cart shift during transport.

Sensors and a three-position actuator guide misaligned cart hooks into a secure hitch latch, improving tugger maneuverability in tight turns.

Sensors track trailer distance and a controller adjusts rear steering to maintain clearance and prevent jackknifing during turns or reversing.

An adjustable clamp pushes the hitch shank against the receiver tube walls to stop rattle while preserving easy insertion.

Multiple rear camera positions triangulate tow ball location, improving trailer assist calibration despite varying tow ball sizes and heights.

A chain-sprocket slider layout triples hydraulic cylinder stroke, giving precise hitch positioning and easy retraction through narrow openings.

An adjustable slide plate clamps the hitch shank against receiver tube surfaces to stop trailer hitch rattle without tightening insertion tolerances.

A crossbeam receiver partly outside the beam uses shaped openings for self-locking towing lug attachment with simpler, lower-cost assembly.

Movable locking linkages let a hitch guide keep coupling alignment while freeing the payload tongue for tight autonomous vehicle turns.

A detachable sealed storage box inside a vehicle hook arm keeps valuables hidden, dry, and harder to steal.

Bi-directional powerline communication lets hardwired vehicle cameras auto-authenticate and send video without extra Wi-Fi hardware.

PLC links tractor and trailer modules through existing power lines so the TMS can verify the assigned trailer and flag unauthorized hookups.

Multiple swivel and height adjustments let a tow vehicle and trailer self-align, cutting repeated hitching attempts despite ball-coupler misalignment.

Force, acceleration, temperature, and inclination sensing are combined to estimate trailer mass accurately under real towing loads.

Threaded joints, snap-fitting, and latch locks solve loose tow hook connections while keeping installation and disassembly fast and stable.

Motorized hitch arm and drive systems automate trailer ball alignment, cutting hookup time and reducing operator exposure in harsh conditions.

A biasing member holds the tow hook secure for towing, then lets it retract under reverse impact loads to reduce vehicle and obstacle damage.

Angularly spaced locking surfaces let a trailer coupling secure only working and rest positions, reducing mechanism complexity and transition noise.

Local weakenings around the towage bushing restore symmetric bumper deformation and more uniform energy absorption during repairable impacts.

A forward, higher telescoping hitch uses damped extension and a support frame to spread trailer load across all tires for steadier towing.

An over-center spring pin lets the trailer coupler latch onto a hitch ball and reset automatically, reducing manual actuation and wear.

Embossed receiving planes and a welded sleeve help a bumper cross member mount a tow lug with precise alignment and stronger load transfer.

Active OBD-linked control coordinates trailer brakes, cargo systems, and sensors to replace passive, closed vehicle diagnostics.

A bellows with preload and magnetic sealing keeps the coupling ball protected when coupled or uncoupled while allowing lubricant to spread.
