Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Previous abrasion-resistant coatings for flooring surfaces have been inefficient due to excessive use of abrasion-resistant particles like aluminum oxide and a lack of consideration for the size distribution of these particles, leading to suboptimal usage and performance.
Innovation Solution
A curable coating composition with a binder comprising acrylate-functional compounds and diamond particles of specific size distribution (average size between 2 µm and 50 µm with a narrow standard deviation) is applied in multiple layers, allowing for controlled thickness and particle placement to enhance abrasion resistance and gloss retention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If large amounts of abrasion resistant particles (aluminum oxide) are used, then abrasion resistance is improved, but material cost and coating complexity increase
Solution Approach 1:
The patent changes the key parameter from particle material type to particle size distribution. By using diamond particles with a narrow size distribution (standard deviation less than 35% of average particle size) in the optimized size range of 2-50 micrometers, the coating achieves superior abrasion resistance with significantly reduced particle loading compared to conventional aluminum oxide coatings.
Solution Approach 2:
The patent creates a composite coating system combining diamond particles of controlled size distribution with a curable coating matrix. This composite structure optimizes the interaction between particles and matrix, allowing efficient particle distribution and reduced particle content while maintaining enhanced abrasion resistance.
2Ease of manufacture
If abrasion resistant particles are added without considering size distribution, then coating formulation is simplified, but particle usage efficiency decreases
Solution Approach 1:
The patent introduces precise control over particle size distribution as a critical formulation parameter. By specifying that diamond particles shall have a standard deviation less than 35% of the average particle size within the 2-50 micrometer range, the patent optimizes particle packing and distribution efficiency in the coating matrix.
Solution Approach 2:
The patent applies uniform particle size characteristics throughout the coating formulation, ensuring consistent particle-matrix interaction and optimal abrasion resistance properties across the entire coating layer.
3Manufacturing precision
If multiple coating layers are applied with controlled thickness ratios, then surface finish and particle embedding are improved, but manufacturing complexity increases
Solution Approach 1:
The patent divides the coating application into multiple layers with specific thickness ratios (0.6:1 to 2:1 between consecutive layers). This segmentation allows progressive particle embedding and surface smoothing, with each layer contributing to the final surface quality and particle distribution.
Solution Approach 2:
The patent applies preliminary partial curing to coating layers before subsequent layer application. This preliminary action stabilizes the underlying layer, preventing particle displacement while maintaining the structured multi-layer architecture for optimal surface finish.
4Reliability
If diamond particles are properly embedded in coating matrix, then abrasion resistance is enhanced, but particle dislodgment risk under shear force increases
Solution Approach 1:
The patent optimizes the coating matrix thickness relative to particle size (maintaining specific thickness ratios), ensuring adequate matrix coverage and bonding around each diamond particle. This parameter optimization enhances particle embedding depth and bonding strength, preventing dislodgment under shear forces while maintaining abrasion resistance.
