Composite Fire Protection Profiles That Bake Together in Fire
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fire protection materials, such as polyurethane cushions and bricks, require numerous units to be joined and cut to size for effective sealing, which is complex and increases material density, compromising fire resistance and installation simplicity.
Innovation Solution
Fire protection profiles made of composite materials with inorganic fiber and film, designed to expand and connect during a fire, reducing density and eliminating the need for complex cutting, achieved through a simplified production method involving a continuous hose filled with intumescent material and divided into pieces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a large number of fire protection units are joined to form a fire stop, then fire resistance is improved, but device complexity and installation time increase
Solution Approach 1:
The patent combines multiple fire protection units into a single modular profile structure. The hollow profile can be filled with fire protection material to create a unified component that provides fire resistance without requiring assembly of multiple separate units, thereby reducing installation complexity while maintaining fire protection effectiveness.
2Adaptability or versatility
If fire protection units are cut to size to adapt to line feedthroughs, then adaptability is improved, but installation time and complexity increase
Solution Approach 1:
The hollow profile is designed with segmentation capabilities, allowing it to be divided into multiple sections or adapted to different sizes while maintaining its structural integrity and fire protection properties. This enables easy adaptation to various line feedthrough configurations without complex cutting procedures.
3Ease of operation
If additional sealants are used to reduce cutting, then installation complexity is reduced, but device complexity and cost increase
Solution Approach 1:
The hollow profile is designed to serve multiple functions: it provides structural support, fire protection, and sealing capabilities in a single component. The profile can be adapted to different applications without requiring additional sealants or auxiliary materials, thereby reducing overall device complexity while maintaining installation simplicity.
4Reliability
If density of fire protection material is increased, then fire resistance is improved, but weight and handling difficulty increase
Solution Approach 1:
The patent utilizes composite material structures within the hollow profile, combining different materials with complementary properties. This allows the fire protection component to achieve high fire resistance through its structural design and material composition rather than relying solely on high density, thereby reducing weight and improving handling while maintaining fire protection effectiveness.
