Preventing Unauthorised/Accidental Actuation TRIZ Cases
- Gas Valve Lock Assembly for Tamper-Resistant Maintenance Isolation
Symmetrical locking elements and spring clips secure the valve actuator to block tampering while keeping gas valve lock assembly simple.
- Segmented Closure Cap With Release Tool for Securing Slide Valves
Segmented locking hooks and a guided release tool secure slide valves against tampering while allowing authorized cap removal.
- Adjustable T-Handle Ball Valve Lockout for Secure Fit
Adjustable slides shrink the stem opening to fit different valve handles securely, preventing lockout removal or drop-off.
- Rotary Actuator Lockout Insert for Multi-Position Lever Fixing
A slotted plate and locking pin let a rotary actuator lever lock at multiple positions without modifying the existing actuator.
- Oil Container Valve Handle Bracket for Anti-Tamper Locking
A channeled bracket, connecting pin, and lock keep the valve handle attached and block unauthorized stud rotation on oil containers.
- Underground Valve Access Monitoring via Sensor Housing
A two-part housing over the valve actuator detects movement and records access timing without securing the valve box.
- Spring-Loaded Valve Lever Locking for Unauthorized Actuation Prevention
A spring-biased blocking element locks the valve lever until deliberate pressure retracts it, reducing accidental or unauthorized actuation.
- Double Paired Water Key Merging Four Valve Shapes
A double paired water key combines four valve shapes into one compact tool for rapid selection.
- Valve Lock Torque Support with Pivoting Arm
Segmented design reduces device complexity while maintaining secure locking through spring-loaded ratchets.
