Electrical Locking Circuits TRIZ Cases
- Motor Vehicle Lock Actuating Element Worm Contour
Longitudinal actuation via a worm contour resolves the conflict between override reliability and manual pivoting range in motor vehicle locks.
- Capacitive Door Handle Electrode Segmentation for False Trigger Reduction
Distinct monitoring zones on multiple electrodes distinguish user presence from environmental interference, reducing false triggers in wet conditions.
- Motor Vehicle Door Handle with Emergency Pivot Mechanism
A motor vehicle door handle pivots about a transverse axis to enable manual operation when the drive element fails.
- Vehicle Door Handle System with Touch Sensing and Dynamic Deployment
A vehicle door handle system uses touch sensing signals to drive a controller for deploying the handle body from a flush position.
- Door Lock Verification via Motor Encoder
Encoder output determines locking mechanism position, eliminating primary sensor failure risks and reducing system complexity.
- Motor Vehicle Lock Servo Drive Housing Sensor Integration
A motor vehicle lock servo drive housing integrates a micro-switch and Bowden cable bearing into a single compact unit secured by a clipped lid.
- Vehicle Door Latch Device with Integrated Interlocking and Operating Units
A vehicle door latch device integrates interlocking and operating mechanisms within a single casing to achieve a compact design.
- Vehicle Closure Lock Rotary Latch Position Detection
A vehicle closure lock uses separate preliminary and main pawls with dedicated sensors to detect rotary latch positions.
- Concealed Door Handle Assembly with Lockable Push-Push Mechanism
A concealed door handle assembly integrates a lockable push-push mechanism to transition between flush and deployed states.
- Rail Vehicle Rotary Latch Locking Mechanism Monitoring
A rotary latch locking device uses a single switch to detect the position of a pivoted locking lever and blocking lever.
- Vehicle Door Actuator for Hands-Free Operation
Actuator moves vehicle door to half-open position via push switch, enabling hands-free access for loaded users.
- Adaptive Vehicle Door Control Modes for Obstacle Avoidance
A vehicle door control system selects automatic or assistive modes based on real-time distance to obstacles.
- Piezoelectric Door Handle Sensor for Gloved Detection
Ridge-patterned piezoelectric sensors detect gloved or wet-hand contact, solving capacitive failure in adverse weather.
- Motor Vehicle Emergency Door Handle Pivot Mechanism
Integrated pivot handle and spring reduce weight while maintaining manual release reliability.
- Door Position Sensing via Accelerometer Integration
Replacing complex absolute sensors with accelerometers eliminates hardware cost while maintaining precise door positioning accuracy.
- Motor Vehicle Door Handle Latching Mechanism
An elastic spring element latches a motor vehicle door handle in its release position, eliminating manual force requirements during mechanical key insertion.
- Vehicle Door Handle Backup Mechanism for Electronic Failure
A vehicle door handle uses a blocking element to enable mechanical unlatching via the grip lever.
- Flush Vehicle Door Handle Actuator Lever Mechanism
Actuator lever drives grip member between flush and active positions, eliminating preliminary flap movements required by traditional designs.
- Interior Door Handle Integrated Pivoting Lever Actuator
Integrates a pivoting lever into the interior door pull handle to resolve space constraints while enabling mechanical emergency operation.
- Concealed Door Handle Microswitch Position Detection
A concealed door handle uses deployment microswitches to detect handle position and signal the vehicle control module.
- Exterior Door Handle Manufacturing with Post-Paint Electronics Integration
Segmenting the manufacturing process allows painting of molded parts before installing electronics, preventing paint particle damage and short circuits.
