Keys TRIZ Cases
- Locking System Key Stop Profile for Secure Axial Alignment
A locking system key stop section limits insertion depth to ensure correct axial alignment.
- Key Identification Scanner Using Shadow Detection and Photodetector Arrays
A key identification scanner uses an illuminated plate and photodetector matrix to capture unique shadow patterns for digital signal generation.
- Lock Cylinder Counter-Abutment Security Mechanism
A lock cylinder employs a spring-biased movable counter-abutment to block rotor rotation, preventing unauthorized access without the correct flat key.
- Deviated Keyway Locking System with Rotating Idler Block
A locking system uses a rotating idler block and translating shields to create a deviated keyway path for secure access.
- Bait Box Maintenance Tool With Rotating Keys
A bait box maintenance tool consolidates multiple keys on a rotating hub to reduce management complexity and prevent loss.
- Key Tool Orthogonal Pin Decoding for Complex Locks
Orthogonal pin translation in a key tool decodes complex locks with large height differences.
- Cylinder Lock Concealing Tumbler Pin Recesses Above Axis
A cylinder lock positions tumbler pin recesses above the rotational axis to conceal them from the keyway interior.
- Automotive Flip Key Rotatable Bearing Torque Resistance
Radially extending legs resist excessive rotation by distributing torque through transverse shear forces, preventing damage from improvised tool misuse.
