Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing composite materials for civil construction suffer from delamination under compression loads, poor bonding between layers, and degradation due to corrosion of iron-based reinforcement elements, leading to reduced durability and structural failure.
Innovation Solution
A multilayer panel comprising a composite of glass fiber impregnated with a thermosetting polymer matrix, a polymer foam core, and a concrete layer, anchored by a 'T' structure at the ends of the side faces to ensure all layers work together, resisting both tensile and compressive loads without delamination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If steel structures are used for civil construction, then mechanical strength and load-bearing capacity are improved, but susceptibility to corrosion and fire risk worsen
Solution Approach 1:
The patent employs a composite structure combining steel beams with concrete slabs and polymer foam insulation layers. The steel provides mechanical strength while the concrete and polymer layers protect against corrosion and fire, creating a composite construction system that integrates multiple material properties to simultaneously achieve strength and reliability.
2Strength
If steel structures are used for civil construction, then mechanical strength is improved, but fire risk increases
Solution Approach 1:
The patent introduces polymer foam insulation layers and concrete as intermediary protective barriers between the steel structure and fire exposure. These layers act as thermal insulation mediators that slow heat transfer to the steel, delaying thermal degradation and maintaining structural integrity during fire events.
Solution Approach 2:
The composite construction system combines steel with fire-resistant materials (concrete and polymer foam) to create a multi-layered structure where each material contributes its advantageous properties - steel for strength, concrete and polymer for fire resistance.
3Strength
If conventional construction methods are used, then structural integrity is achieved, but energy loss through insulation worsens
Solution Approach 1:
The patent creates a composite wall and panel system integrating structural steel elements with thermal insulation materials (polymer foam and concrete). This composite approach allows the structure to simultaneously provide mechanical support and thermal insulation, reducing energy loss while maintaining integrity.
Solution Approach 2:
The concrete and polymer foam layers serve multiple functions: they provide thermal insulation to reduce energy loss, contribute to fire resistance, and add structural mass. This multi-functionality allows a single construction system to address both structural integrity and energy efficiency requirements.
4Loss of energy
If monolithic insulation panels are used, then insulation performance is improved, but adaptability to complex geometries worsens
Solution Approach 1:
The patent divides the insulation system into separate modular components - polymer foam insulation panels and concrete panels that can be independently manufactured and then assembled together. This segmentation allows each component to be produced with standard geometries while the assembled structure can accommodate complex building shapes and configurations.
