Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current fire-resistant building elements, particularly those using aluminum profiles, face challenges in maintaining load-bearing capabilities and aesthetic finishes due to the degradation of composite materials at high temperatures, and the complex process of assembling multiple slabs or shaped inserts.
Innovation Solution
A fire-resistant building element design featuring a main metal hollow profile with a pressure plate and a fire-resistant insert composed of interconnected external and internal tubular profiles filled with composite material, allowing for easy integration and stable fastening, which maintains integrity and load-bearing capabilities even at high temperatures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the composite material of the fire-resistant insert is exposed to high temperatures during final treatment, then the aesthetic finish can be applied, but the composite material loses its fire-retarding properties
Solution Approach 1:
The fire-resistant insert is divided into two separate tubular profiles (external and internal) that are interconnected but can be manufactured and treated independently. This segmentation allows the external profile to receive high-temperature aesthetic finishes while the internal profile with composite material maintains its fire-retarding properties by avoiding direct exposure to finishing temperatures
Solution Approach 2:
The internal tubular profile is nested within the external tubular profile, creating a concentric structure. The internal profile containing the composite material is protected from high-temperature exposure during aesthetic finishing of the external profile, while both profiles work together to provide fire resistance
2Reliability
If multiple slabs or shaped insert parts are used to fill the profile, then fire resistance can be achieved, but the assembly process becomes complex and time-consuming
Solution Approach 1:
The external and internal tubular profiles are interconnected to form a single integrated fire-resistant insert unit. This merging of components simplifies the assembly process by reducing the number of separate parts that need to be assembled, while maintaining the fire resistance properties through the combined structure
Solution Approach 2:
The interconnected tubular profile structure serves multiple functions simultaneously: it provides fire resistance through the composite material, enables aesthetic finishing of the external surface, and simplifies assembly as a single integrated unit. This multi-functionality improves productivity without compromising fire safety
3Ease of manufacture
If the fire-resistant insert is placed before final treatment, then the structure can be assembled, but the composite material is damaged by high temperatures
Solution Approach 1:
By segmenting the insert into external and internal profiles, the patent enables selective placement and treatment. The external profile can be placed before final treatment for aesthetic finishing, while the internal profile with composite material is protected from temperature damage, maintaining manufacturing precision
4Weight of moving object
If aluminum profiles are used for frame structures, then the structure is lightweight, but the profiles lose load-bearing ability and melt in high temperatures
Solution Approach 1:
The patent uses composite materials by combining aluminum profiles with fire-resistant composite material filled in the internal chamber. This composite construction maintains the lightweight property of aluminum while adding fire resistance and load-bearing capability through the composite material that does not melt at high temperatures
Solution Approach 2:
The nested structure of internal and external tubular profiles creates a protective configuration where the internal profile with composite material reinforces the aluminum external profile, maintaining load-bearing ability during fire exposure while preserving the lightweight characteristic
