Building Locks TRIZ Cases
- Cable Interlock System for Furniture Drawer Safety
Flexible cables anchor to furniture and drawers, preventing simultaneous opening while absorbing transit impacts.
- Self-releasing Ceiling Latch for Tool-free Panel Removal
A self-releasing ceiling latch uses a front-mounted mechanism to enable tool-free panel installation and removal.
- Pivoting Cover Lock Mechanism for Narrow Space Stability
A pivoting cover lock mechanism uses a latch moving in an intersecting direction to engage a recessed portion.
- Door Handle Bearing Screwless Clamping Mount
Rotating the lower rosette expands nested clamping sections radially, eliminating screw installation complexity while maintaining non-rotatable fixation.
- High Security Striker Box Assembly Design
Segmented striker box assemblies with divergent screws resist lateral kicks by distributing impact forces across multiple structural dimensions.
- Anti-tamper Cam System with Dual Mechanical Locks
Dual mechanical locks require a dedicated key to rotate the cam, preventing tampering while maintaining reliable switch operation.
- Automatic Shootbolt Mechanism for Door Alignment
An automatic shootbolt assembly uses a biasing member and actuation lever to extend the bolt upon door closure.
- Lock Swing Bolt Housing Edge Anti-Pushback
A lock housing edge collides with the pivot bolt body to prevent unwanted rotation.
- Window Fitting Hand Lever Mounting with Axial Force Absorption
Polygonal shaft coupling with a wave washer isolates axial loads from the drive mechanism, preventing gear wear while enabling secure hand lever attachment.
- Lockset Safety Mechanism Preventing Unauthorized Access
A lockset safety mechanism uses a spring-loaded push rod to block unauthorized access.
- Automatic Foldable Door with Two-Way Structure for Narrow Space Safety
Segmented door leaves with electromagnetic buckles allow automatic release in emergencies, preventing evacuee injury from wide swing radii.
- Pivoting Lock-out Bar for Electrical Panel Security
A pivoting lock-out bar secures electrical panels using L-brackets and a padlock.
