Towing Devices TRIZ Cases

A motorized pin-lever and ramp assembly automates hitch alignment and locking, enabling secure remote coupling without manual pin insertion.

A spring-biased locking pin and pivoting lever simplify trailer hitch alignment, reduce hand force, and auto-lock the hitch ball.

Matching indicia on the ball mount and trailer coupler simplify size selection, avoid test fitting, and reduce towing connection errors.

Camera-based hitch verification detects trailer connection defects and alerts the driver before towing with an unsafe latch, chain, or harness setup.

A hydraulic piston raises and lowers the gooseneck ball coupler to eliminate manual cranking and safer solo trailer hitching.

Adjustable cross-member and tow-coupling interfaces fit different vehicle chassis without welding, cutting parts count and assembly cost.

Real-time tongue-load measurement and spring bar tilt adjustment speed hitch setup and help prevent sway and axle overloading.

A waterproof elastic cover and rigid helmet assembly protect a tow hitch ball from weather while adding a football-themed appearance.

A rotary handle, rod, and ramped surfaces simplify trailer hitch ball locking while adding a secondary pin lock for more secure attachment.

A removable two-point tie-down secures gooseneck safety chains without drilling extra bed holes or obstructing the load bed.

Sensor-guided control lets a trailer coupling arm detect contact, retry movement past soft obstacles, and reduce damage or injury risk.

A damping element slows the towing hook near its end position so load sensing can stop motion before harmful motor currents and torques rise.

A compact compliant moment bar improves trailer weight distribution, cuts setup effort, and reduces sway and traction loss on uneven terrain.

An elastic deformation section at adjacent vehicle joints disperses bending stress, extending wire harness life and sorting stability.

A 3D marker and virtual prepositioning point let a vehicle align with a trailer kingpin more accurately during autonomous coupling.

A lower-modulus moment bar expands preload adjustment range, improving trailer hitch stability and traction on uneven roads.

Direct sensing of the ball neck tracks rest, working, and intermediate positions to improve trailer coupling movement control and obstacle detection.

A hinged clamshell lock encloses the trailer coupler and hitch ball receiver to deter theft while protecting exposed wiring from damage.

A magnetic field sensor detects active and inactive lock positions in a trailer coupling, enabling clear locking confirmation and defect detection.

A flexible pin assist adds grip and controlled tension so retaining pins can be inserted or removed in recessed, rust-prone locations without tools.

An elastic sleeve keeps trailer safety chains tensioned so they avoid ground drag yet still extend for turning without binding.

A detachable hitch-mounted A/V unit projects sound beyond the vehicle cabin with water-resistant, battery-powered outdoor playback.

A linear actuator adjusts spring arm tension remotely to speed hitch setup, balance axle loads, and improve towing stability.

A microcontroller-controlled gladhand lock blocks unauthorized tractor air-line coupling and verifies digital certificates for secure trailer connection.

A removable interposer and hitch pin block unauthorized trailer coupling, delivering low-cost theft prevention without cumbersome locks.

An oblique channel and recessed outlet route sensor wiring through the coupling ball and ball neck without weakening the hitch.

A hitch- or ground-mounted bracket with cruciform shuttles and straps makes outdoor strength training portable while keeping resistance adjustable.

An outrigger base plate ties the center socket to forward puck receivers, spreading offset towing loads to reduce torsion and socket failure.

A spar-and-extension coupling rigidly joins modular vehicles in motion despite misalignment, avoiding operator intervention and electronic alignment.

A cushioned T-shaped trailer boot sheath uses segmented coverage and a mold fit to protect hitch components from impact, rotation, and weather.

A sliding torsion bracket with a threaded bolt enables under-load hitch adjustment without uncoupling torsion arms, cutting setup time.

A recessed draw bar preserves secure, adjustable hitching while clearing the MultiPro tailgate and enabling stowage without removing the ball mount.

An ECU uses the towing vehicle's reverse-light signal to hold flat-towed wheels straight, preventing jackknifing and tow bar damage.

Hydraulic slide assemblies move the hitch in and out, side to side, and up and down so one driver can align and connect a trailer alone.

A lubricant channel and plug keep the trailer ball socket wet, reducing abrasion, shock loads, and disconnection risk during towing.

Multiple rigid drawbar mounting positions correct coupling height mismatch, keeping trailers level for safer braking and lower tire wear.

A compliant moment bar and pivoting latch simplify hitch setup while reducing trailer sway and maintaining stability on uneven terrain.

A removable adapter plate, shank, and bed protection plate secure truck cranes to a gooseneck hitch without truck bed damage.

A passive trailer reflector and towing-vehicle ultrasonic sensors measure articulation angle without wiring, while adapting to different wheelbases.

A parallelogram linkage lets the tow coupling height be fixed at different positions, maintaining stable and torsion-resistant towing across vehicle heights.

A displaceable tow hook mount stays secure during towing but moves under impact loads to preserve bumper force distribution and crashworthiness.

A hybrid shank with arc and flat contact surfaces fits round or square hitch sockets while maintaining secure load transfer.
