Flexible Porous Composite Structure for Crack-Tolerant Masonry Insulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing building materials fail to effectively address cracks and deformations in masonry structures due to low deformability, requiring time-consuming and costly applications that often compromise energy efficiency and aesthetic preservation.
Innovation Solution
A multilayer flexible structure with a resin matrix embedding functional fillers, where the resin penetrates into a fibrous support, providing mechanical anchorage and stability, while leaving a non-impregnated layer to absorb deformations and offer thermal or acoustic insulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If locally applied reinforcement materials with high modulus of elasticity are used to seal cracks, then crack opening is sealed, but the material breaks once it reaches elastic limit allowing crack to travel outside
Solution Approach 1:
The patent changes the mechanical parameters of the reinforcement material by using polymer impregnated into the fibrous support, creating a material with appropriate deformability and elasticity that can accommodate structural movements without breaking, thus maintaining crack sealing effectiveness while preventing crack propagation
Solution Approach 2:
The patent creates a composite structure by impregnating polymer material into a fibrous support, combining the strength of the fibrous network with the flexibility and adhesive properties of the polymer, resulting in a reinforcement material that both seals cracks and resists propagation under structural stress
2Use of energy by stationary object
If rigid boards are applied to masonry for thermal and acoustic insulation, then energy efficiency is improved, but the structure cannot absorb deformations from masonry movements
Solution Approach 1:
The patent uses a flexible fibrous support structure instead of rigid boards, allowing the insulation layer to adapt to masonry movements and deformations while maintaining thermal and acoustic insulation performance, thus resolving the contradiction between rigidity for insulation and flexibility for movement accommodation
Solution Approach 2:
The patent changes the physical state and mechanical properties of the insulation material from rigid to flexible by using a fibrous support structure, enabling the material to maintain insulation effectiveness while accommodating structural deformations and movements
3Shape
If conventional plasters and paints are applied to masonry, then aesthetic appearance is achieved, but they cannot withstand masonry movements causing flaking and peeling
Solution Approach 1:
The patent changes the mechanical properties of the plaster and paint materials by incorporating polymer components that provide elasticity and deformability, allowing the finishing layers to withstand masonry movements without flaking or peeling while maintaining aesthetic appearance
