Passenger Lock Actuation TRIZ Cases
- Vehicle Door Locking Mechanism Blocking Key-Based Outside Opening
An inner-handle-actuated stopper blocks outside opening with an authorized key while preparing the vehicle door for user re-entry.
- Vehicle Door Locking Mechanism With Inner-Handle Stopper Release
An integrated stopper blocks control-paddle rotation from outside and moves to an unblocking position when the inner handle opens the door.
- Vehicle Door Latch Over-Center Spring Axial Positioning
Ribs on the spring support shaft prevent axial deviation of the over-center spring coil, stabilizing lock lever switching against vehicle vibration.
- Vehicle Door Handle Input Lever Sub Plate Support
A sub plate supports the input lever shaft to prevent inclination, maintaining base plate thickness and formability.
- Vehicle Sliding Door Relay Mechanism With Independent Lock Levers
A relay mechanism for vehicle sliding doors uses separate outer and inner lock levers to control latch release via a ratchet system.
- Motor Vehicle Door Lock Actuation Force Reduction
Cam and spring unit create unstable equilibrium to lower actuation force, resolving the trade-off between structural simplicity and ease of operation.
- Child Protector Bush Retention Mechanism
Position retaining means between the first lever and bush prevents movement errors, ensuring accurate actuation stroke transmission.
- Motor Vehicle Door Lock U-Shaped Spring Composite Design
A motor vehicle door lock uses a steel spring with distinct contour and fixing limbs to actuate a plastic control element.
- Vehicle Door Latch Switching Element One-Motion Operation
Integrated switching element merges double locking control with release linkage, reducing device complexity while maintaining anti-theft capability.
- Asymmetrical Toggle Spring Child Lock Mechanism
A child lock mechanism uses asymmetrical toggle springs to provide distinct tactile feedback for position verification.
- Motor Vehicle Door Lock Clutch Lever Segmentation
Segmented clutch levers reduce assembly complexity in motor vehicle door locks while maintaining reliable child safety locking functions.
- Dual Pull Latch Assembly Preventing Accidental Release
A double cable pull assembly uses a selector lever and linkage to secure vehicle panels.
- Motor Vehicle Door Lock Child Safety Indicator
An integrated switching indicator light illuminates the rotary latch inlet mouth, resolving visibility issues in dark garage environments.
- Childproof Lock Mechanism Segmentation for Assembly Efficiency
Segmenting the childproof lever allows independent projection movement, resolving cover complexity constraints while improving assembly efficiency.
- Universal Vehicle Door Latch for Rod or Cable Actuation
A universal vehicle door latch uses a single outside handle lever to secure either a rod or cable actuator.
- Motor Vehicle Locking Device Spring Lip Control Element
Segmented spring lips on the control element increase deflection stability by 25%, resolving elasticity trade-offs in high-strength plastics.
