Power Transmission/Actuator Features TRIZ Cases
- Motor Vehicle Door Lock Latching Element for Low-Friction Opening
A pivotable latching element and evoloid gear stage cut rotary latch-pawl friction, enabling compact, lower-power door lock opening.
- Vehicle Lock Sealing for Emergency Unlock Without Moisture Ingress
A sealed through-hole and dry-wet housing split enable manual emergency unlocking while blocking moisture and dirt from the drive.
- Vehicle Door Flush Handle Assembly With Mechanical Backup
A compact lever-and-spring flush door handle keeps a smooth exterior while adding manual deployment and key-based backup during electronic failure.
- Motor Vehicle Door Lock Emergency Release Reset Mechanism
A spring- or handle-reset emergency release enables tool-free door lock opening after drive failure while staying concealed behind trim.
- Integrated Powered Door Latch for Thin-Wall Camper Doors
A single-bolt latch with frame-side electronics fits thin camper doors, enabling solenoid, key, and inside lever operation without door wiring.
- Motor Vehicle Door Lock Bidirectional Slotted Link for Stable Coupling
A bidirectional slotted link separates engagement and disengagement paths to stabilize the coupling lever and prevent lock malfunctions.
- Motor Vehicle Lock Coupling Lever With Bidirectional Slotted Link
Separate pin paths in a bidirectional slotted link stabilize a vehicle lock coupling lever and prevent disruption-prone motion.
- Vehicle Door Handle Assembly With Cam-Lever Tolerance Control
A cam-and-lever handle mechanism reduces play, wear, and tolerance sensitivity while keeping vehicle door handle extension smooth and secure.
- Motor Vehicle Lock Release Lever for Manual Lockout
A shared release lever enables motorized and manual pawl lifting while blocking manual actuation in idle stroke without extra coupling parts.
- Vehicle Latch Actuator With Single-Motor Crash Unlock
A single motor and actuator gear handle both power release and crash unlock, keeping the vehicle latch compact and operable in collisions.
- Single-Motor Closure Latch Assembly for Multi-Function Door Release
One motor drives pawl release, double-pull mechanical release, and child lock functions to cut door latch size, complexity, and cost.
- Spring-Assisted Motor Vehicle Lock Drive for High Sealing Forces
A pre-tensioned leg spring helps a motor vehicle lock drive overcome door sealing pressure with lower motor load and simpler gearing.
- Two-Part Vehicle Door Lock Release Lever for Blockage Recovery
A linearly displaceable coupling lets a two-part release lever decouple under blockage so the pawl returns home and the door can close.
- Vehicle Door Lock Linkage for Stable Child-Safety Engagement
An integrated locking linkage simplifies vehicle door lock transmission while keeping child-safety engagement secure and stable.
- Compact Child-Lock Module for Vehicle Door Lock Assemblies
A stacked movable-arm locking module adds child safety to vehicle door locks while cutting structure complexity and saving installation space.
- Vehicle Door Latch Kinematics for Persistent Unlock After E-Release
Coordinated mechanical and electrical release kinematics keep the locking lever unlocked after e-release, preventing vehicle lockout.
- Vehicle Door Latch Override Lever for One- or Two-Motion Release
An interchangeable override lever lets one vehicle door latch meet one- and two-motion release rules without separate latch designs.
- Flush Door Handle Actuator With Position-Based Motor Shutoff
An integrated position indicator stops the motor at deployed and recessed handle positions, avoiding stall wear and external limit switches.
- Vehicle Door Latch With Parallel Mechanical-Electrical Unlocking
Parallel mechanical and electrical release paths keep the locking lever unlocked after opening, preventing vehicle door lockout.
- Vehicle Door Latch Layout for Compact Dual Release Mechanisms
A common-shaft latch layout fits electrical and mechanical door release functions into limited space while preserving modularity and override features.
- Vehicle Door Latch Override Geometry for Release Rule Switching
An interchangeable override lever shape lets one vehicle door latch meet one- or two-motion release rules without redesign.
- Vehicle Door Latch Layout for Thin Independent Release
Separate shafts for the mechanical lever and electric gear wheel cut door latch thickness while keeping both release paths independent.
- Vehicle Door Latch Two-Shaft Layout for Reduced Thickness
A central opening lever with separate electric and mechanical pivot points cuts latch thickness while preserving independent door release.
- Vehicle Door Latch Lever Decoupling for Motor-Failure Closing
When a release motor fails, a manual cancellation mechanism decouples latch levers so the vehicle door can still be closed securely.
- Vehicle Door Lock Release Using GPS and Smartphone Authentication
GPS, Bluetooth, and smartphone authentication let a vehicle door lock open only at the delivery location, with offline emergency access.
- Vehicle Door Lock Ratchet Release With Compact 3D Motor Layout
A spiral-groove actuator shifts the ratchet in one rotation, shrinking door lock layout and cutting parts, noise, and rebound.
- Refuse Vehicle Tailgate Locking Assembly for Faster Unloading
An actuator-driven locking arm secures the refuse vehicle tailgate automatically, cutting cycle time and extra actuator complexity.
- Vehicle Door Latch Assembly with Single-Motor Crash Unlock
A single motor reconfigures the latch between power-only release and crash-ready mechanical opening, keeping the assembly compact and economical.
- Motor Vehicle Lock Coupling for Pawl Reset After Blocking
A switchable coupling lets a blocked locking pawl return to the lowered position, preserving vehicle lock closure in motorized or manual use.
