Flush Fire Door with Segmented Vertical Frame
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fire protection doors and windows have complex frame structures with protruding profile elements that compromise aesthetics and increase temperature loads during fires, limiting design options and fire resistance.
Innovation Solution
A flush and form-fitting connection of fire protection panes with non-combustible building material boards or wooden elements, held on two sides instead of four, using a high-temperature silicone adhesive with intumescent material for secure bonding and enhanced fire resistance, and incorporating a sealing arrangement for improved smoke and fire protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fire protection panes are held by profile elements forming a frame on all four sides, then the glass pane is securely held, but the structure becomes complex and profile elements protrude beyond the pane
Solution Approach 1:
The patent removes the horizontal profile elements (friezes) from the frame structure, extracting only the necessary vertical profile elements to hold the glass pane. This simplifies the overall structure while maintaining the secure holding function through the remaining vertical profiles and glazing beads.
Solution Approach 2:
The frame structure is segmented into only the essential vertical profile elements rather than a complete four-sided frame. The glass pane is held by these segmented vertical profiles with glazing beads, eliminating the need for continuous horizontal framing elements.
2Reliability
If profile elements and glazing beads are used to hold the fire protection pane, then the pane is securely fixed, but temperature load increases during fire events
Solution Approach 1:
The patent extracts the horizontal profile elements that created thermal bridges and concentration points for temperature loads. By removing these friezes and reducing the frame to essential vertical elements only, the structure has fewer points where heat concentrates during fire events.
Solution Approach 2:
The patent applies glazing beads only where absolutely necessary for secure fixation rather than continuous framing. This localized approach to fixation reduces the overall thermal mass and heat transfer paths in the frame structure during fire events.
3Reliability
If protruding profile elements are used to hold the glass pane, then the pane is securely mounted, but aesthetic impression is impaired
Solution Approach 1:
The patent removes the protruding horizontal profile elements (friezes) that disrupted the aesthetic appearance. Only essential vertical profile elements remain, creating a cleaner, more streamlined visual appearance while maintaining secure mounting through these reduced elements and glazing beads.
4Reliability
If all-glass door design is used, then design options are limited, but fire and smoke protection is achieved
Solution Approach 1:
The patent combines fire protection glass panes with a simplified frame structure made of vertical profile elements and glazing beads. This composite construction achieves fire and smoke protection requirements while the modular nature of the simplified frame allows for greater design flexibility compared to traditional four-sided framing.
Solution Approach 2:
The door leaf is segmented into fire protection glass panes and a minimal vertical profile frame structure. This segmentation allows the glass areas to be optimized for fire protection while the simplified frame provides structural support and design flexibility, enabling various configurations.
