Movable Gate Segments Fire Protection Textile Transition Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Gates with movable segments face challenges in fire protection due to weak points in the transition areas between segments, which can compromise the integrity of fire-resistant materials and allow the spread of fire and smoke.
Innovation Solution
The implementation of a gate design that includes a profile frame with a fire protection material covering at least one outside area of each segment, and a fire protection textile that bridges the transition area between two neighboring segments, enhancing fire protection without significantly increasing manufacturing costs or altering the gate's mobility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fire protection material is applied to the profile frame and fire protection textile is installed across transition areas, then fire protection properties are significantly improved, but device complexity and manufacturing costs increase
Solution Approach 1:
The patent applies fire protection measures specifically at the transition areas between door segments, which are identified as the critical weak points for fire spread. The fire protection textile is installed only at these transition zones rather than uniformly across the entire door structure, providing targeted protection where it is most needed while avoiding unnecessary complexity in other areas.
Solution Approach 2:
The patent combines different fire protection materials - fire protection material applied to the profile frame and fire protection textile installed across transition areas - to create a composite fire protection system. This multi-material approach enhances overall fire resistance by addressing different aspects of fire protection (structural integrity and gap sealing) with appropriately suited materials.
2Object-affected harmful factors
If fire protection material and fire protection textile are added to seal transition areas, then fire spread prevention is improved, but manufacturing costs increase
Solution Approach 1:
The fire protection measures are concentrated specifically at the transition areas between door segments, which are the critical pathways for fire and smoke spread. By targeting only these high-risk zones rather than treating the entire door uniformly, the patent achieves effective fire protection while minimizing material costs and manufacturing complexity.
Solution Approach 2:
The patent uses fire protection textile as a flexible sealing element that can be installed across the transition areas. This textile acts as a thin film barrier that effectively blocks fire and smoke spread through the gaps between segments without requiring complex rigid structures, thereby reducing manufacturing costs while maintaining protection effectiveness.
3Reliability
If fire protection measures are implemented at transition areas, then fire protection properties are improved, but the mobility and operational efficiency of the gate may be reduced
Solution Approach 1:
The fire protection textile used in the patent is a flexible element that can accommodate the movement and deformation of the door segments during operation. This flexibility ensures that the fire protection barrier remains intact and effective even when the gate is in motion, maintaining both fire protection properties and gate mobility without compromise.
Solution Approach 2:
The fire protection system is designed to be dynamic rather than static, with the fire protection textile capable of moving and deforming along with the door segments. This dynamic design allows the fire protection measures to adapt to the operational states of the gate, ensuring continuous protection during opening, closing, and intermediate positions without restricting mobility.

AI summary
In a gate (100) with at least two gate segments (10) which are movably connected to each other via hinge elements, each gate segment (10) has a profile frame (20) which defines a segment plane (E) and is fitted with at least one panel (25). In each gate segment (10), the profile frame (20) is provided with a fire-resistant material (30) on at least one outer surface of the gate segment (10) with respect to the segment plane (E), and furthermore, two adjacent gate segments (10) are connected by a fire-resistant textile (35) spanning the transition area between the two gate segments (10).
