Solution Overview
Problem
Current flooring products fail to provide effective slip resistance for both shod and barefoot traffic, often being too rough, difficult to maintain, or aesthetically unpleasing, and there is a lack of solutions that work well with all types of footwear.
Innovation Solution
A curable particulate coating composition with particles of specific size range (60-120 µm) is applied to flooring materials, comprising a curable polymer and particles, which provides a non-slip surface suitable for all types of footwear and bare feet, while being easy to maintain and aesthetically appealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If particles with size range from 60 to 120 µm are used in the coating composition, then non-slip properties are improved, but viscosity increases making application more difficult
Solution Approach 1:
The patent applies parameter changes by precisely controlling the particle size within the range of 60-120 µm and maintaining particles at 30% by weight of the coating. This specific parameter range optimizes the balance between non-slip performance and coating viscosity, ensuring the coating remains applicatable while providing effective slip resistance.
2Reliability
If larger particles are used to improve non-slip properties, then slip resistance increases, but surface roughness increases making the surface harder to clean
Solution Approach 1:
The patent resolves this contradiction by optimizing the particle size to 60-120 µm, which is large enough to provide effective slip resistance but small enough to maintain surface smoothness for easy cleaning. The 30% weight concentration further optimizes this balance.
Solution Approach 2:
The coating composition creates a composite material system combining polymer matrix with specifically sized particulate matter, achieving a synergistic effect where the controlled particle distribution provides slip resistance without creating excessive surface roughness that would hinder cleanability.
3Reliability
If more particles are added to enhance non-slip properties, then slip resistance improves, but the coating becomes more difficult to apply and less uniform
Solution Approach 1:
The patent maintains particles at 30% by weight of the coating, which is the optimal concentration that provides sufficient non-slip properties while preventing excessive viscosity that would compromise coating uniformity and applicability.
4Ease of operation
If particles smaller than 60 µm are used, then viscosity decreases improving applicability, but non-slip properties are insufficient
Solution Approach 1:
The patent establishes 60 µm as the minimum particle size threshold, below which non-slip properties become insufficient. This lower bound ensures particles are large enough to provide effective slip resistance while the upper bound of 120 µm prevents excessive viscosity.
