Shutters/ Movable Grilles TRIZ Cases
- Bent Sheet Metal Rolling Shutter Slat for Compact Retraction
A single bent steel sheet forms secure interlocking shutter slats that cut roll-up diameter while lowering cost and improving durability.
- Loading Bay Safety Barrier With Vertical Closure and Impact Locking
A vertically moving loading bay barrier uses guides, rollers, and locking hooks to save space while resisting forklift impacts.
- Baby Gate Topper With Pivoting Apron to Prevent Climbing
A flexible pivoting apron raises baby gate height without adding rigid leverage, helping block climbing while preserving gate stability and adult access.
- Stacking Panel Door Cam Levers for Higher Vertical Clearance
Cam levers and wheeled end caps lift and separate door panels for vertical stacking, increasing clearance and enabling panel-by-panel repair.
- Expandable Barrier Hinge for Partial Aisle Enclosures
A central hinge and scissoring sections let temporary barriers form partial or full aisle enclosures with stable adjustable angles.
- Shading Box Closure With Removable Frame and Power Receptacle
A removable frame closure gives tool-free access to shading box components while adding battery contact, fastening, and cable routing without wall damage.
- Ramp Gate Sealing Structure for Low-Heat-Loss Closure
A flexible side seal and guide arrangement helps ramp gates close reliably despite channel tolerances while reducing heat loss.
- Insulated Window Receiving Frame With Integrated Roller Shutter Box
A pre-assembled insulated frame integrates the roller shutter box to cut thermal bridges, improve air tightness, and simplify facade installation.
- Insulated Window Gantry Structure for Flush Facade Integration
A thermally insulating gantry fits within facade cladding to house shades, avoid thermal bridges, and simplify opening installation.
- Roller Shutter Guide Rail With Elastic Clamping Compensation
An elastic clamping member stabilizes roller shutter guide profiles, compensating for dimensional variation and preserving precise alignment.
- Roller Shutter Slats With Integrated Lattice Mosquito Net
Integrated lattice slots let roller shutter slats pass air and light while forming a mosquito barrier without extra accessories.
