Fireproof Doors TRIZ Cases
- Frameless Fire Protection Glass Door with Intumescent Sealing
Removing visible frames from the closure eliminates visual obstruction while intumescent seals maintain fire protection properties.
- U-Profile Frame with Undercut Grooves for Fire Door Assembly
Undercut grooves in a U-shaped frame profile accept cover elements, simplifying assembly while maintaining fire protection integrity.
- Non-flammable Glass Balustrade Interlayer
Potassium silicate interlayers replace flammable PVB to resolve fire safety and load-bearing strength contradictions.
- Intumescent Strip Placement on Steel Fire Door Frames
Localizing intumescent material prevents frame deformation while maintaining reliable fire sealing.
- Fire Door Sash Frame Using Non-Separated Profile
A fire door sash frame uses a thermally non-separated profile to eliminate bimetallic warping in the wing structure.
- Flood Seal Arrangement for Low Threshold Doors
Segmented gaskets with deformable protrusions improve sealing under water pressure without increasing door closing force.
- Eccentric Axis Escape Door Torque Mechanism
Eccentric pivot axes convert excess tunnel pressure into opening torque, eliminating costly wall bulges while maintaining gas-tight seals.
- Pivotable Smoke Door With Nested Screen For Ventilation
A pivotable smoke door uses a nested screen to create a large ventilation aperture within the existing frame structure.
- Three-Layer Window Joint Sealing System for Moisture and Heat Regulation
A three-layer sealing system uses vapor-permeable exterior and low-permeability interior layers to regulate moisture flow in window joints.
