Locking Wings Simultaneously TRIZ Cases

A lead screw, cable levers, and a spring structure let one actuator cinch multiple vehicle door latches despite stroke differences.

Integrated primary and secondary latch mechanisms let pillar-less vehicle doors release independently while improving selective security control.

A material shield extends into the tailgate striker notch to block debris, protect latch function, and keep cargo contained.

When autonomous driving stops unexpectedly, door lock control switches by occupant presence to preserve escape access or protect goods.

Automatic compartment locks tied to ignition, key, or park status add theft protection for valuables stored inside vehicles.

A fixed lower hinge and lower edge lock keep the hinge triangle stable when the sliding door closes, improving support and water sealing.

A multi-locking vehicle door structure uses one input to unlock coordinated upper and lower doors for easier bidirectional access.

Automatic locking ties glove box and sub-compartment access to ignition, key, or park state to deter theft without slowing owner access.

One mobile command locks vehicle doors plus trailers or roof boxes, while status feedback removes manual key checks and lock-by-lock inspection.

Coaxial rods and anchors lock sliding doors into an A-to-C pillar load path, limiting side-impact intrusion without sacrificing ingress or egress.

Interlocking door-mounted members reinforce B-pillarless vehicle doors during side impacts by holding the doors closed and limiting intrusion.

Closure speed, acceleration, and travel time are monitored to block locking during rapid door slams and protect the mechanism from impact damage.

Two separate actuator displacements and dual ASIL-B control units prevent unintentional vehicle flap opening while keeping the lock simple.

Immediate re-locking of a mechanical changeover door lock prevents careless handle openings while balancing child safety, theft deterrence, and access.

Hardened steel guard plates prevent drill and pry bar access, resolving the security vulnerability of standard locks while maintaining ease of operation.

A double-leaf vehicle door device uses a pre-locking function to hold the first leaf closed until the second leaf arrives.

Sensor detects door apparatus engagement from inside the vehicle to trigger processor notifications, resolving child lock exit capability bottlenecks.
