Door/Window Protective Devices TRIZ Cases
- Sliding Folding Shutter Drive with Pivoting Levers
Segmented pivoting levers align shutter elements in a common plane while reducing drive device complexity.
- Motorized Home Automation Screen Wind Control via Threshold Positioning
Wind sensors trigger segmented screen positions to reduce structural stress and noise while maintaining partial sun protection.
- Side-Inserted Cord Rolling Device for Window Blinds
Relocating the cord rolling device to the beam end eliminates central interference during blind assembly while maintaining reliable lift transmission.
- Shutter Open-Closing Apparatus Simplifies Fire Door Mechanism
A shutter open-closing apparatus uses a link unit driven by main door movement to operate fire shutters without separate motors.
- Insulated Glazing with Low-Emissive Sunblind
A sunblind with a low-emissivity layer reflects infrared radiation within the insulated glazing unit.
