Wood Veneer Floor Panel Edge Coating Against Wear and Moisture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Veneer parquet panels are susceptible to scratches, wear, and moisture penetration, particularly at the edges, due to their mechanical sensitivity and capillary effects in wood grain vessels, leading to discoloration and reduced durability.
Innovation Solution
A floor panel design with a wood veneer layer of 1 mm or less, featuring a lacquer layer extending to the side edges containing hard particles, and a glue layer with larger hard particles embedded beneath the veneer, enhancing wear and moisture resistance while maintaining aesthetic appeal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a thin wood veneer layer (1 mm or less) is used for veneer parquet, then the panel achieves aesthetic appeal and cost-effectiveness, but the panel becomes sensitive to impressions and scratches with insufficient mechanical features
Solution Approach 1:
The patent applies composite materials by combining a thin wood veneer layer with a resin-impregnated substrate and incorporating hard particles (such as aluminum oxide or corundum) into the resin layer. This creates a composite structure that maintains the aesthetic properties of thin veneer while providing enhanced mechanical strength, wear resistance, and impact resistance through the reinforcing hard particles distributed throughout the resin matrix.
2Ease of manufacture
If soft wood species are used for the backing layer, then the panel achieves cost reduction, but the panel becomes scratch-sensitive and lacks sufficient mechanical features
Solution Approach 1:
The patent applies local quality by differentiating the properties of different layers: the thin top veneer layer provides aesthetics, the soft wood backing layer provides cost-effectiveness and cushioning, while the resin-impregnated intermediate layer with hard particles provides localized wear and scratch resistance at the critical interface between the veneer and substrate.
3Device complexity
If traditional lacquer coating is applied only on the surface, then the panel maintains simplicity of application, but the side edges remain vulnerable to moisture penetration and discoloration
Solution Approach 1:
The patent extends the protective lacquer coating from the traditional two-dimensional surface application to a three-dimensional coverage that includes the side edges of the veneer panel. This dimensional extension ensures that moisture barriers are applied to all exposed surfaces, preventing capillary action in the wood grain vessels at the edges while maintaining a relatively simple application process.
4Strength
If hard particles are embedded only in the surface lacquer layer, then the panel achieves wear resistance, but the particles may not sufficiently protect against penetration through the thin veneer
Solution Approach 1:
The patent incorporates hard particles into the resin-impregnated substrate layer before the thin veneer is applied. This preliminary action ensures that the hard particles are positioned beneath the veneer surface, creating a reinforced substrate that prevents penetration from below while the surface lacquer layer with additional hard particles provides wear resistance from above, creating a dual-layer protection system.

AI summary
A floor panel with a substrate, a decorative layer of wood veneer with a thickness of 1 millimeter or less on the substrate, and a lacquer layer including transparent or translucent surface material on the wood veneer. The lacquer layer can have hard particles. The lacquer layer can extend from the upper surface of the wood veneer at least up to a side edge of the wood veneer, such that the side edge is at least partially covered by the lacquer layer.
