Vehicle Locks TRIZ Cases

Aircraft overwing exit door uses a piano hinge and crank system to simplify passenger operation.

A pivotable plate mechanism prevents rear door opening until the front door opens, reducing manufacturing complexity and accidental damage risks.

A vehicle door lock uses a centering and guide wedge to maintain proper alignment of the rotary latch during engagement.

Integrating support rails with the latch mechanism reduces component count and weight while maintaining stable door positioning.

A vehicle door hold lock mechanism uses a dual grip assembly to securely engage the door component.

Radial cam positioning and flexible rocker mediation lower friction and assembly difficulty in compact fuel tank lid locks.

A torque dividing arrangement redirects drive reaction torque to a locking transmission.

Microcracked chromium layers on primer substrates enable LF and RF antenna detection while maintaining a premium metallic texture.

A tractor bonnet lock rod uses a surrounding member to protect the release end.

A retention assembly secures coupled door handle assemblies using magnetic and mechanical interlocking elements.

A vehicle latch handle assembly uses a flexible bezel finger to pivot the grip while maintaining a straight cable pull path.

Offset surfaces in a cylindrical casing accommodate hasp variations, preventing tampering without damaging enclosures.

A bidirectional hinge cover slides and rotates to seal large containers.

A plastic joint securing device uses a snap-in latching section to attach levers without tools.

Additional upper handles allow cab door opening from elevated positions, preventing interior energy loss and environmental exposure.

A vehicle hood apparatus raises both ends to the rear upper side using a segmented hinge mechanism.

An oblique movement mechanism clears finger interference during pulling, enabling a natural ergonomic grip.

Integrating the closure block into the hinge arm eliminates external locking devices, reducing weight and complexity while maintaining secure door closure.

A bistable spring urges a lever between locking and release positions to control the storage lid movement.

Protruding wall section on steering column engages lock unit groove to distribute rotational forces and prevent cracking during forced wheel rotation.

A dual-function fastener secures a preassembled lock cylinder unit to the inner door side using aligned holes in the hood and carrier.

A vehicle push-lifter uses a lower drainage portion and upper air vent to manage fluid flow within the case.

A motor vehicle lock uses pawl and catch contours to drive cinching movement without a separate drivetrain.

A vehicle handle device uses a connection aid with a guide hole to stabilize inner cable posture during assembly.

Counter-balancing springs offset ramp wall weight for single-user operation, while an integrated locking assembly secures the wall and prevents interference.

A mechanical child lock uses a low-friction plastic lever to rotate a coupling finger within a cavity.

A hinged metal housing fully encloses cargo door seals to prevent accidental breakage during transit.

A triggering lever with a pivotably attached coupling lever actuates two separate latching devices simultaneously for motor vehicle doors.

A pivoting stop lever and actuating handle assembly secures vehicle cargo doors in the open position.

A cam mechanism rotates gripping jaws via a yoke to distribute sealing pressure evenly and prevent accidental release.

Eliminating an intermediate base lever reduces component count and assembly complexity while improving operational response speed.

An oblique slide-in link guides the lock cylinder housing into a bearing bracket receptacle, preventing removal by a single force to enhance break-in security.

A slidably supported second bracket engages with a key cylinder turning arm to secure the rear seat of a saddle riding vehicle.

Segmented rotor and bar fuse zones break under forceful rotation, blocking control means while preserving legitimate key operation.

A latch locking mechanism uses a spring and stopper to maintain the closed position of the latch body within an enclosure.

A vehicle double-pull lock uses a Bowden cable to actuate a catch and pawl mechanism for sequential hood opening.

Inclined contact surface in vehicle door handle lever mechanism increases rotational torque with minimal operational force.

Coaxial pins and a helical spring secure the protective flap, preventing accidental disengagement of key-operated mechanisms.

A frangible lock insert shatters upon force, breaking the ignition circuit.

A film hinge connects a movable cover to a vehicle lock housing, enabling latching positions that resolve obstruction during Bowden cable installation.

Asymmetric gibbous pins constrain lateral movement in exterior handles, eliminating looseness during operation.

Rotating rollers on a bar lock absorb lateral truck movement to prevent surface marring and corrosion.

A lockable device expands within a zero turn radius vehicle control lever slot to block movement.

A pivotable support arm articulates between a rest and functional position to secure the tailgate in open configurations.
