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.

Merging two latches into one center pillar component reduces vehicle weight and manufacturing cost while allowing either door to initiate operation.

A door locking device uses a control unit to authenticate an external transmitter for electric release.

A two-stage tailgate uses a dual latch mechanism controlled by a single handle to open half and full doors independently.

A powered latch controller manages vehicle door unlatching through specific user input sequences and communication status checks.

A vehicle door lock control algorithm uses proximity sensors to detect objects within the swing radius and automatically locks the door.

A door lock state determination device calculates elapsed unlock time to identify operational faults without adding hardware.

A vehicle child lock latch system uses a controller to engage or disengage locks based on proximity signals from blind spot detection devices.

Routing Bowden cables through the hinge eliminates damage risks in confined cargo spaces while maintaining secure multi-point engagement for large doors.

Actuator drives slider and bolt to lock parcel doors, eliminating physical key management complexity.

A reinforcement member surrounds a vehicle side door lock to disperse impact loads.

A powered door latch system uses a controller and user communication device to display emergency release information.

A powered latch controller adjusts unlatching requirements based on vehicle speed and crash signals to secure door retention.

A driverless vehicle control module generates unique digital keys upon door closure to authenticate users and unlock compartments.

A motor vehicle door lock device uses an electric release mechanism to actuate the opening lever for swift door access.

A motor vehicle door lock uses a sensor to detect actuating lever chain status, enabling a control unit to manage functional positions and simplify production.

Hardened steel guards encase the sliding lock rod to prevent drilling attacks that compromise standard puck locks.

Sandwiching detection switches between terminal rows reduces wire length and device volume in the vehicle door lock apparatus.

Decoupling the control contour from the locking element resolves reliability versus complexity trade-offs in motor vehicle door locks.

A vehicle location device calculates the ratio between signal strength variation and acceleration variation to determine portable device distance.

Multiple trigger operations override faulty locking mechanism sensors, enabling reliable electromotoric opening without mechanical backup.

A dual function electronic control unit uses a convertible receptacle circuit to switch between operational modes.

A vehicle locking system uses a low-frequency coil to power a passive transponder for emergency access.

Modular aluminum panels create a sealed storage space that protects cargo from elements while integrating ventilation and power systems.

Adaptive filtering of ultra-wide band signals determines key fob positions, resolving low frequency antenna precision limits.
