Tractor-Trailer Combinations TRIZ Cases

An actuator shifts the coupling sensor follower between sensing and release positions to cut load during trailer coupling and disengagement.

A stress-absorbing front coupling and rigid slave links keep articulated vehicles aligned while allowing pitch and independent post-deployment driving.

A rotor-mounted plug and damped coupling axis separate connection from hitching to prevent damage under misalignment, tilt, and vibration.

Ultra-wideband sensing tracks kingpin coupling position despite grease and metal chips, reducing sensor count and improving fault recognition.

A camera-detected trailer marker is transformed into 3D kingpin position data, enabling precise autonomous coupling with less damage risk.

A rail-mounted chain bracket secures gooseneck safety chains without drilling the frame, preserving strength, warranties, and bed clearance.

A kingpin-coupled optical encoder with LIDAR measures trailer articulation, helping autonomous yard tractors reverse and place trailers safely.

A laterally offset camera on the bearing element keeps the kingpin in view while reducing dirt buildup and impact risk during coupling.

Real-time kingpin force sensing drives trailer motor torque to counter lateral and longitudinal loads, improving tow stability and fuel use.

A movable camera inside the fifth wheel contour retracts during coupling to avoid damage while preserving precise trailer alignment.

Movable tractor and trailer coupling heads align air and electrical lines automatically, cutting manual docking time, labor, and yard complexity.

A suspended gooseneck pin box enables direct ball coupling without adaptors, reducing king pin stress and preserving trailer stability.

Automated dock-ready signals control a king pin interlock so shunt trucks cannot move trailers before loading dock conditions are safe.

Interlocking flanges, friction bushings, and multi-point fasteners simplify hitch alignment while distributing loads on a single shear surface.

A bearing-mounted camera stays outside grease spray and king pin impact zones while preserving clear alignment visibility during coupling.

Magnetic flux sensing tracks fifth wheel lock position to verify kingpin engagement, detect wear, and prevent towing disengagement.

Pivoting support arms brace a detached gooseneck against the tractor, preventing bounce and unsafe manual support during loading.

Movable tractor and trailer coupling heads align air and electrical lines automatically, cutting manual hookup time and system complexity.

A magnet-coupled rotary encoder with compliant springs measures tractor-trailer articulation accurately while tolerating alignment variation.

Stored hitch position and heading let a towing vehicle return to a parked trailer and couple automatically without manual alignment.

A moving-frame torsion coupler absorbs vertical and direction-of-travel towing forces while avoiding moment arms and offset loading.

A driven cover mechanism shields plug contacts until alignment is complete, cutting coupling force, damage risk, and contamination.

Multiple rear cameras identify trailer type and coupling features to guide hitch alignment, cut repeated maneuvers, and reduce contact risk.

Patterned closed-end reliefs in a fifth wheel hitch plate retain and spread grease, extending surface life while avoiding added lubrication hardware.

Cam-actuated fasteners and biasing members let a fifth wheel hitch mount attach securely in tight truck beds while accommodating under-bed tolerance stack-ups.

Mounting the camera on an insertion flange keeps it away from wheel dirt, grease, and king pin impact while improving trailer alignment.
