Towing Devices TRIZ Cases

Synchronous radar modules coordinate via a data bus to determine trailer connection states, resolving contradictory clutter indicators in blind spot detection.

A torsion adapter absorbs transient forces between a trailer tongue and coupler, preventing loss of control.

Integrating the handle rod with a flush-mounted key mechanism eliminates bulky protrusions that catch debris while securing the tow ball against theft.

Composite tow bars accommodate vehicle attitude variations through articulated joints while maintaining structural integrity via biased cam locking mechanisms.

A storage system secures weight distribution bars and hitch heads to trailer frame rails.

A pin-drop hitch mount assembly uses a biased latch to automatically return the fastening pin to an unhitched position.

A reducing pin sleeve adapts trailer hitch drawbars to accept high-strength 5/8-inch pins.

A trailer hitch locking mechanism uses a spring-loaded blocking body to secure the coupling arm against lateral movement.

A trailer hitch pivot bearing uses interlocking groove and projection elements to create a larger effective radial surface area.

A pivoting clamshell guard encases the trailer hitch coupler to block unauthorized removal.

Remote release of a tow bar latch prevents drivetrain damage during high-speed hybrid vehicle aerodynamic drag testing.

A tapered shoulder bolt drives an expansion sleeve to grip a draw bar inside a hitch receiver tube.

Extensions on the towing device hold sensors that detect rear-side surroundings, resolving information loss caused by obstruction from the towed vehicle.

Embedded metal stamping secures a rubber bumper to the jack stem, eliminating tailgate damage during lifting operations.

Nesting pivot bearing elements reduces the volume of a motorized trailer coupling while maintaining structural integrity.

Asymmetric trapezoidal geometry eliminates lateral play while plastic plates reduce friction during length adjustment.

Parallel support planes in connecting rods pre-retain a towbar crossmember, eliminating manual holding and reducing factory assembly time.

A modular trailer hitch system uses a resilient member to absorb towing impacts and protect vehicle structures.

Rotating coupling disc translates eccentric bearing hub motion to adjust adjacent cart spacing.

A telescoping trailer hitch assembly with adjustable shaft apertures and strap members secures hitch ball elevation.

Welded fastening socket in bumper beam bulkhead secures tow eyelet without weakening structural integrity.

A trailer coupling integrates a spring-loaded release position latching device to secure the actuating body during pivoting movements.

Segmenting the cross member into a tubular torsionally stiff structure and a planar tensilely stiff structure reduces mass without compromising stability.

Segmenting the hitch into a removable coupler and fixed base eliminates custom installation requirements while freeing truck bed space when not towing.

A bent composite moment bar varies hitch preload by flipping its orientation to adjust tension.

Locking pivot joints convert the towing assembly from an articulated extraction mode to a rigid triangular configuration for secure road towing.

Arched webs in trailer hitch connection parts absorb torque peaks elastically, minimizing structural damage to the vehicle body.

Replacing four rigid plates with three pivoting units eliminates wear gaps and maintains clamping force.
