Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current waterproofing technologies for solid-phase concrete are inadequate, necessitating the development of additional methods to enhance the waterproofing of concrete substrates.
Innovation Solution
A composite structure comprising a solid-phase concrete base-substrate component with a mesh component of non-woven polymeric strands, a substantially planar component, and an adhesive-layer component, where the polymeric strands are fused to form a three-dimensional structure with a thickness of at least three millimeters, and the adhesive-layer is attached to both the planar component and an exterior or interior sheet, providing improved mechanical attachment and waterproofing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a liquid-applied coating or paint is used for waterproofing concrete surfaces, then the waterproofing function is provided, but the mechanical attachment and structural integrity are insufficient
Solution Approach 1:
The patent applies composite materials by combining a mesh component made of polymeric strands with a concrete base substrate. The mesh component is embedded into the concrete, creating a composite structure that integrates the waterproofing function with enhanced mechanical attachment and structural integrity, resolving the contradiction between waterproofing reliability and mechanical strength.
2Ease of manufacture
If a simple coating is applied to concrete, then the application process is simple, but the resistance to salt, corrosion, and barnacles is insufficient
Solution Approach 1:
The patent uses a composite structure consisting of a mesh component embedded in concrete, which provides enhanced resistance to salt, corrosion, and barnacles. The mesh component acts as a reinforcement layer that protects the concrete substrate from these harmful factors while maintaining ease of application through the embedding process.
3Strength
If the mesh component thickness is increased to at least three millimeters, then the tensile properties are improved, but the device complexity increases
Solution Approach 1:
The patent applies local quality by creating a three-dimensional mesh structure with specific thickness (at least three millimeters) only where tensile strength is needed for waterproofing and structural reinforcement. The mesh component is embedded into the concrete substrate, providing enhanced tensile properties locally at the interface without requiring complex structural modifications throughout the entire system.
