Keys TRIZ Cases
- Key Rib Control Planes for Lock Cylinder Security
A key shaft features a longitudinally extending rib with multiple adjacent control planes that interact with pin tumblers in the lock cylinder.
- Lock Cylinder Control Ring and Pin Mechanism
Distinct control pin locations across lock families enable unique key interactions while preventing unauthorized access.
- Helical Keyway Locking Device Pick Resistance
A helical keyway guides a matching blade to rotate the core.
- Lock Key with Irregular Sinuous Channel for Anti-Copying
Irregular sinuous channel in lock key blade enables variable width and depth indentations that prevent fraudulent copying and bumping attacks.
- Lock Cylinder Anti-Theft Mechanism Using Auxiliary Pin Tumblers
A lock cylinder assembly incorporates auxiliary pin tumblers and positioning pins to secure the locking mechanism.
- Key Blank Identification via Bitting Analysis
Imaging system extracts bitting data to compare against known blanks, resolving accuracy issues in manual replication.
- Locking Device Radial Projections Anti-Picking
Radial projections engage annular channels to prevent unauthorized rotation, resolving security vulnerabilities against picking tools.
- Key Light Device Visual Feedback Electromechanical Lock
A key light device uses color and flashing patterns to communicate access authorization status via integrated electronics.
- Flat Key Profile with Paracentric Grooves for Anti-Copying
Paracentric triangular grooves prevent accurate replication by circular saws and 3D printers, ensuring copied keys remain unusable.
- Lock Cylinder with Asymmetrical Attachment Element for Key Restriction
A lock cylinder uses an attachment element to partially cover a symmetrical key channel, restricting insertion to specific reversible key profiles.
- Cylinder Lock Anti-Burglary Pin and Slide Mechanism
A cylinder lock uses hardened metal additional pin assemblies and profiled slides to engage key wave grooves for secure operation.
- Cylindrical Key Plug Profile Member Cavity Design
Segmented cavities hold non-rotatable profile members, freeing internal volume for additional locking tumblers and simplifying manufacturing.
- Lock Cylinder Key Partial Obstruction Bypass
A lock cylinder key bypasses partial obstructions in the keyway using a narrowed shaft and transverse cut-outs.
- Lock Tumbler Cut Determination via Acoustic Vibration Analysis
Acoustic vibration analysis determines tumbler cuts without disassembly, eliminating damage risks and trial-and-error key testing.
- Detainer Disc Locking System With Deviated Picking Path
A detainer disc locking system uses a deviated key and idler block to rotate the cylinder bidirectionally.
- Key Safe with Rotating Housing and Wiping Lock
A key safe uses a rotating housing part and an internal wiping mechanism to obscure the combination lock coding elements during entry.
