Shutters/ Movable Grilles TRIZ Cases
- Slatted Door Impact Resistance via Hook Channel Segmentation
Hook and channel connections distribute impact forces along slat length, preventing dislodgment without increasing weight.
- Articulated Door Lamellae Spiral Joint Design
Spiral joint geometry prevents unintentional unhooking while enabling easy assembly.
- Winding Shaft Box Fastening Bracket for Tool-Free Installation
A connecting bracket with a clip adapter enables tool-free lateral attachment of winding shaft boxes to window frames.
- Hem Bar with Movable Weather Strip for Uneven Surfaces
- Roller Shutter Box Twin-Wall Design for Rigidity and Drainage
Symmetric recesses allow identical components for left and right covers, reducing manufacturing complexity while improving installation flexibility.
- Blind Slat Control System Modular Connecting Box
Segmented connecting boxes and endless screws allow individual slat replacement without dismantling the entire shutter, reducing maintenance complexity.
- Roller Blind Slat Longitudinal Folds for Acoustic and Structural Performance
A roller blind slat uses internal longitudinal folds to create a double-thickness aluminum structure that enhances mechanical rigidity.
- Arc-Shaped Guard Mechanism for Protective Housing
Curved guide sections reduce travel distance and friction losses while absorbing acceleration forces during rapid opening cycles.
