Shutters/ Movable Grilles TRIZ Cases
- Foam Roller Shutter Insulation With Integrated Coupling Sections
A foam insulating material incorporates functional elements produced exclusively by a foaming process to create secure plug-and-latch connections.
- Roller Shutter Profile Bar Connection with Guide Housing
Segmented connecting elements nested inside guide housings allow profile bars to fold while maintaining alignment and preventing light gaps.
- Dual-Plane Blind Head Rail with Independent Roller Channels
Independent upper and lower rollers store opaque and translucent panels in a slim head rail, reducing friction between moving parts.
- RF Coupler Printed Transmission Line PCB Footprint
Printed transmission line replaces bulky coils to reduce printed circuit board area while maintaining high current capacity and manufacturing reliability.
- Safety Gate Spinning Mechanism for Compact Storage
A safety gate cover body winds around a spinning mechanism to reduce storage footprint.
- Retractable Safety Gate Control Assembly Simplification
Integrating a ratchet unit with a spiral spring into the control assembly reduces structural complexity and manufacturing costs for retractable safety gates.
- Roller Shutter Guiding Device for Polygon Effect
An adjustable guiding mechanism prevents polygon effect and shaking in high-speed roller shutters.
- Reusable End Cap for Window Covering Rail via Elastic Bias
Elastic arcuate end cap resolves reuse versus securement trade-off by flattening to maintain tight fit during repeated installation.
