Keys TRIZ Cases
- Lock Cylinder Key Profile Design for Hierarchical Master Keying
Segmented vertical ridges and grooves on the key blank enable hierarchical master keying, resolving security versus manufacturing complexity.
- Sinusoidal Flat Key Profile for Cylinder Lock Anti-Picking
A flat key with sinusoidal lateral surfaces creates a paracentric profile that blocks electro-picking wires while maintaining structural stability.
- Cylinder Lock Axial Tumbler Stacking for Compact High-Variation Design
Axial tumbler stacking resolves the contradiction between reducing cylinder core diameter and maintaining reversible key strength.
- Positional Multiplex Keyway System for Hierarchical Lock Extension
A positional multiplex keyway system extends lock hierarchies using a narrowed foot and key projection to control vertical pin stack alignment.
- Locking System Contact Surface Coding via Magnetic Orientation
Magnetic coding elements attach to base bodies in arbitrary rotational positions, eliminating mechanical stops and reducing manufacturing complexity.
- Lock Cylinder Key Sequential Release Mechanism
Varying flank contour angles in lock cylinder keys enable sequential blocking element release.
- Deviated Key Locking System with Rotating Idler Block
A deviated key rotates an idler block to align pin slots within a lock cylinder.
- Foldable Keycard for Vehicle Access
A foldable keycard aligns segmented blade layers to form a functional mechanical key within a credit-card-sized profile.
- Motor Vehicle Key Anti-Spreading System for Torque Stability
An anti-spreading mechanism prevents the key case from opening under high torque, ensuring reliable locking operations without housing failure.
- Disc Cylinder Key Shank with Oblique Connecting Section
A key shank features a narrowed, obliquely oriented connecting section that resists unauthorized picking tool insertion.
- Locking Cylinder Two-Row Tumbler TSA006 Key Security
Two-row tumblers and a deeper furthest tumbler prevent unauthorized tool insertion into the keyway.
- Hollow Key Shank with Internal Coding Tracks for Lock Security
Internal coding tracks in a hollow key shank prevent visual scanning while maintaining structural strength through segmented design.
- Two-Part Key With Segmented Safety Openings
Segmenting safety openings into through and blind holes prevents tool access, stopping loosening while keeping manufacturing simple.
- High-Security Locking Device With Multi-Face Encryption
A high-security locking device uses a reversible flat key with multiple encryption grooves and alveoli to ensure correct rotor alignment.
- Key Blade Undercut Groove Prevents Cross-Keying
An asymmetric key blade featuring a single-sided undercut groove aligns with specific lock cylinder projections to prevent cross-keying vulnerabilities.
