Towing Devices TRIZ Cases

A spring-loaded plunger catches the shank aperture for fast hitch alignment, then locks the pin to stop transverse play and rattling.

Sectional crashbox support on the crossbeam lowers the initial impact force peak while preserving crashbox strength and simple manufacturing.

A lever-driven vertical plunger presses on the hitch attachment arm to cut noise, sway, and wear while resisting debris interference.

A box-structured tow bar end section improves torsional load distribution and towing strength while reducing material use and weight.

Movable side impact elements and energy absorbers let a rear cross member take sliding impacts without damaging the central unit or vehicle body.

A sliding drawbar retracts into a housing and locks in place, cutting trailer protrusion during transport and easing unloading.

An integrated hitch ball and retention coupling measures tongue weight while allowing controlled sliding to improve towing stability and tire loading.

A rotatable pulley body with split shackles improves rope threading, adapts traction angles, and reduces stress concentration and equipment damage.

A telescoping jack and spherical link assembly spreads trailer tongue weight across all wheels to keep the tow vehicle level and stable.

A two-arm lock secures hitch pins around the receiver tube to prevent lost parts, tampering, and accidental trailer disconnection.

A pivoting hitch offsets narrow towed items into the rearview mirror using a lockable flat bar and semi-circular channel.

A holding jaw and vertical groove tighten the hitch ball connection, improving RV towing stability and speeding assembly and disassembly.

Angle-dependent restoring force returns a carried vehicle pivot toward neutral to prevent sideways orientation and keep towing smooth.

A one-way wrap spring clutch holds the tow hitch arm in stowed or deployed position, blocking vibration-driven reverse movement.

A groove-and-pin positioning layout keeps the first mount body strong while allowing height adjustment and easier tow ball size changes.

A movable steering linkage lets the towing ball shift and steer for faster hookup, easier disassembly, and more stable RV towing.

A telescoping sleeve and load cell measure trailer tongue weight at the correct hitch height, helping prevent sway and tow vehicle overload.

Rotating semi-spherical ball locks and tapered prongs create a more secure trailer attachment during maneuvers, heavy towing, and uneven terrain.

Built-in threaded tow points on the front frame eliminate aftermarket base plates and reduce flat-tow installation time and disassembly.

Timed latch actuation and wireless attachment ID help the controller avoid false attached or detached states during hitch operation.

A single motor and gear mechanism moves coupling arms into position to tow a cart while avoiding the complexity of dual-side couplers.

An under-trailer gateway uses one cable through the kingpin plate to link trailer devices directly with tractor electrical systems.

A forward-extending mounting bracket boosts tow hook rigidity and towing strength while preserving rope and bull bar clearance.

A rotating base plate and bearing let the recovery shackle self-align with load direction, improving side-load capacity and pin safety.

A U-shaped bumper with a triangular brace doubles as a towing receiver, letting firefighting vehicles move aircraft while protecting onboard monitors.

An angled, rearward-releasing tow hook stays secure for towing but breaks away in low-speed impacts to protect bumper and airbag components.

A clevis pin with equidistant edges lets the vehicle lug nut wrench adjust or detach the tow hook without a separate tool.

A pin-positioned mounting block and spacing column let one hitch assembly match different tow heights without separate fixed hitches.

An adjustable clamp and attachment-arm assembly adds towing capability to rear or box blades while staying secure and easy to remove.

Wireless trailer coupling control uses sensor-based visual feedback and color-coded status display to confirm locking and load state.

A vehicle hitch anchor moves the attachment point close to the ground, combining secure mounting with quick setup for portable rope workouts.
