Wing Handles TRIZ Cases
- Smart Door Lock Transmission Mechanism for Peephole Attack Prevention
A smart door lock transmission mechanism switches between connected and blocked states based on sensing signals.
- Espagnolette Lock Nut Triggering Mechanism
Dual-direction nut actuation releases stored energy via decoupled mechanisms, resolving tolerance-induced button failure.
- Intelligent Lock Proximity Mode and RF Shielding
Configurable proximity modes and RF shielding prevent unintentional activation while maintaining ease of access for authorized users.
- Portable Generator Lock with Variable Depth Lever
A portable generator lock uses a rotating handle to drive a sleeve along an axis, positioning the locking lever for secure engagement.
- Interchangeable Toggle Handle Set for Privacy and Passage Modes
A handle set uses a toggle mechanism with interchangeable heads to switch between privacy and passage modes.
- Piezoelectric Door Release Powered by Energy Harvester
A piezoelectric energy harvester converts door kinetic motion into electrical power for the release actuator.
- Motorized Door Opener for RF-Shielded Chambers
A motorized door handle grabber rotates handles to enable independent access.
- Rotating Cylinder Lock Guiding Structures for Assembly Alignment
Asymmetric cross sections and curved surfaces guide lock transmission elements into engaging grooves, resolving assembly alignment difficulties.
- Handle with Embedded Surface-Modifying Substance for Hygiene
Embedded surface-modifying substances in deformable plastic handles prevent microorganism colonization without skin absorption risks.
- Hinged Locking Shroud for Doorknob Security
A hinged locking shroud covers a doorknob with a spring-loaded latch to block keyhole picking.
- Universal Cam Interface for Lockset Actuation
A modular pushbutton mechanism uses a cam interface to correlate rotational and axial movements.
- Rotary-Handle Latch with Electrical Feedback for Aircraft Doors
A rotary-handle latch uses a plunger and electrical switch to signal locked positions.
- Sliding Sash Secondary Lock Mechanism
A sliding sash secondary lock uses a spring-biased pin to engage header apertures for intermediate positioning.
