Shutters/ Movable Grilles TRIZ Cases
- Tensioned Sheet Wall System for Wind Load Resistance
Flexible sheet wall system uses longitudinal tensioning assembly to secure weather enclosure across building openings.
- Inspection Cover Lock with Pivotable Profile for Roller Shutter Box
Segmented profiles and dynamic locking reduce installation time while maintaining secure attachment.
- Adjustable Slat Mobile Screen Control for Vision and Safety
Dynamic control switches between progressive and simultaneous blade orientation based on screen position to balance field of vision with safety.
- PVC-Free Window Slat Material Using Mineral-Polyolefin Composites
Mineral-polyolefin composite slats eliminate dioxin risks from incineration while preserving impact resistance for window coverings.
- Roll-Up Door Guide Rail S-Shape Condensation Drainage
An S-shaped guide rail section directs curtain condensation into a gutter, preventing water fallout on the floor.
- Adjustable Width Barrier With Telescoping Locking Arm
Telescoping barrier and sliding locking arm adapt to varying opening widths while maintaining reliable pressure fit engagement.
- Sliding Window Security Panel with Automatic Locking
A sliding security panel system covers windows to block visibility and resist penetration using composite materials.
- Roller Shutter Box Closure Device With Flexible Sealing Stoppers
Pre-drilled openings with removable flexible stoppers maintain sealing performance while allowing installation adaptability for winding mechanism boxes.
- Retractable Door Sill With Adjustable Torsion Spring
Adjusting rod and ratchet mechanism modify torsion spring deformation to resolve fixed force trade-offs in retractable door sills.
- Force Indicator for Child Safety Gate Installation
Pressure-installed child safety gate uses lower and upper force indicators to display visual representations of proper installation status.
- Tunnel Box Connecting Means Integration
Embedding connecting means in side wall recesses maintains smooth exteriors while enhancing structural stiffness and wind resistance.
- Roller Shutter Box Top Side Sound Insulation
Sound insulation on the top side of a roller shutter box absorbs acoustic energy and dampens vibrations, reducing noise permeability through gaps.
- Stereoscopic Locking Connecting Assembly for Door Guardrails
A connecting assembly uses transverse and longitudinal locking devices to secure door guardrail components in two dimensions.
- Security Grille Chain Mechanism for Sag Prevention
Segmented shafts and a chain drive replace heavy rolling cylinders, reducing sagging risks while maintaining structural strength across wide openings.
- Box Body with Transverse Grooves for Thermal Bridge-Free Lintel Connection
An inverted U-shaped box body uses transverse grooves to nest a junction piece, preventing thermal bridges between lintels and joinery frames.
- S-Shaped Modular Slat for Independent Air and Light Control
Elongated modular slats use an S-shaped channel to manage airflow and light transmission independently.
- Interlocking Slats with Retention Grooves for Wind Load Resistance
Segmented slats engage guide walls via retention grooves to withstand wind loads and prying forces without permanent structural damage.
