Puzzle Locks TRIZ Cases
- Garage Door Parcel Receiver with PIN-Secured Aperture Access
See how a lockable aperture frame installed in a garage door uses PIN access and spring-loaded
- Cipher Wheel Lock Reset Structure for Stable Code Changes
An auxiliary guide block extends reset-cam travel to prevent cipher wheel overshoot and keep lock code changes accurate and stable.
- Seed Phrase Disk Assembly for Concealed Crypto Key Storage
Encoding disks on a holding rod conceal seed phrase order, improving physical crypto backup security against theft or loss.
- Combination Padlock Reset Lever to Prevent Accidental Code Changes
A reset lever and clutch mechanism let users change a padlock code only at the correct combination, preventing accidental resets in normal use.
- Coded Lock Inner Wheel Mechanism for Self-Service Password Retrieval
A spare-key-driven inner wheel and spring mechanism lets users recover a forgotten coded lock password without professional unlocking.
- Combination Lock Bushing Layout for Code Retrieval and Anti-Probing
Unique groove positions in lock bushings let users recover forgotten combinations while making probing attacks harder.
- Bottom-Opening Password Lock With Integrated Code Adjustment
Integrated clutch sleeves and password wheels help prevent unauthorized code changes while simplifying bottom-opening lock assembly.
- Combination Lock Reset Mechanism for Secondary-Access Detection
Heart-shaped cams uncouple the setting wheels and reset the combination code after secondary-lock access, alerting authorized users.
- Anti-Detection Combination Lock with Split Gear Mechanism
An anti-detection piece restrains lower gears while upper gears rotate, limiting password deduction from click sounds.
- Programmable Combination Lock with Keyed Override and Nested Rings
Nested rotatable rings and a keyed override mechanism allow multiple users to share a locker while maintaining independent security codes.
- Safe With Interengaged Panels And Alarm For Tamper Resistance
Interengaged wall panels with resilient spring tabs resist unauthorized access while an integrated alarm system alerts users to tampering attempts.
- Combination Lock Disc Securing Mechanism Prevents Axial Disengagement
A locking lever disc securing portion captures tumbler discs axially to prevent unintended code changes from forced movement.
- Combination Lock Assembly Keyless Access Mechanism
A combination lock assembly replaces physical keys with a rotary code input system for secure access.
- Password Lock Rotating Case Mechanism for Convenient Code Reset
Rotating lock case drives internal cam grooves to automatically reset password wheels without manual buttons.
- Push Button Reset Locking Cap with 4-Dial Combination
A locking cap uses a push button reset mechanism to secure prescription medications against unauthorized access.
- Password Rebound Leaf Mechanism for Repeatable Combination Locks
Movable positioning blocks on rebound leaves allow repeated password digits, expanding combination volume without adding static components.
- Non-intrusive Dial Rotation Detection for High Security Locks
A magnetic rotation detector uses a Hall-effect sensor to identify dial movement without physical contact.
- Dual-Unlock Combination Lock With Independent Password Switch
A dual-unlock combination lock uses a password switch pushbutton to drive a bracket for independent access via two distinct password sets.
- Dog Harness Locking Mechanism Prevents Theft
Combination lock and spring retainers prevent unauthorized removal while allowing easy owner release.
- Resettable Combination Lock Visual Mode Indicator
A resettable combination lock mechanism exposes a visual indicator to signal operational mode changes.
- Auto-Reset Combination Lock Gear Mechanism
A combination lock gear mechanism automatically returns dials to a preset position after use.
- Code-Changeable Dial Wheel Assembly Simplification
An integrated adjuster merges retaining, pushing, and spring functions into one component, reducing assembly complexity while enabling tactile code changes.
- Lock Code Change Without Demounting Using Key Override
A lock mechanism uses a key-operated cancelling means to release button rotation for code changes.
