Shutters/Guards Preventing Contact Access TRIZ Cases
- Rotatable Cable Isolation Structure for Uneven Wiring Space
A rotating isolation piece reshapes cable sections inside an electrical cavity, preventing cross-stacking and easing installation.
- Switchgear Shutter Latch for Safe Maintenance Hold-Open
A spring-loaded hook latch holds switchgear shutters open during maintenance, then self-resets on breaker reinsertion to prevent damage.
- Rotating Switchboard Shutter Structure for Compact Insulation
A pivoting shutter in the switchboard cuts vertical space while preserving insulating distance as the circuit breaker is inserted.
- Filler Plate Deformation Clamping for Loadcenter Deadfronts
Leg deformation clamps a loadcenter deadfront to secure a filler plate, eliminating hazardous drilling and metal shavings during installation.
