Solution Overview

Problem

Existing veneer surfaces face challenges in wear resistance, water resistance, and production cost, particularly when using low-quality or thin veneers, and lack the aesthetic appeal of solid wood surfaces.

Innovation Solution

A method involving a substrate with a sub-layer applied to a veneer layer, where the sub-layer permeates through the veneer under pressure, and a protective thermoplastic layer is applied to enhance wear and water resistance, while the sub-layer's permeation alters the veneer's design.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a thin wood veneer layer is used to reduce production cost, then production cost is reduced, but wear resistance and water resistance deteriorate

Engineering Contradiction:
Improveproduction costVSAvoidwear resistance
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The invention uses a composite structure consisting of a thin veneer layer (0.2-1 mm) combined with a WFF (Wood Fibre Floor) surface layer. The WFF layer comprises wood fibres, binder, and wear-resistant particles (such as aluminium oxide) that provide enhanced wear and water resistance. This composite approach allows the use of thin, cost-effective veneer while achieving the durability properties of thicker, more expensive veneers through the protective WFF surface layer.

Inventive Principle:
Principle #40Composite materials

2Ease of manufacture

If a thin wood veneer layer is used to reduce production cost, then production cost is reduced, but water resistance deteriorates

Engineering Contradiction:
Improveproduction costVSAvoidwater resistance
Core Design Contradiction:
Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The WFF surface layer acts as a protective barrier against water penetration. The mixture of wood fibres, binder, and wear-resistant particles creates a dense, water-resistant surface that protects the underlying thin veneer from moisture damage, enabling the use of cost-effective thin veneer while maintaining water resistance.

Inventive Principle:
Principle #40Composite materials

3Ease of manufacture

If low quality veneer is used to reduce production cost, then production cost is reduced, but aesthetic appeal deteriorates

Engineering Contradiction:
Improveproduction costVSAvoidaesthetic appeal
Core Design Contradiction:
Ease of manufactureVSIllumination intensity

Solution Approach 1:

The invention applies different quality requirements to different layers: the underlying veneer layer can be thinner and lower quality (serving as a cost-effective substrate), while the WFF surface layer provides the aesthetic appearance with its wood fibre composition and natural colour variations. This local differentiation of quality allows cost reduction in the veneer layer without compromising the visual appeal provided by the WFF surface.

Inventive Principle:
Principle #3Local quality

4Reliability

If a protective thermoplastic layer is applied to enhance wear resistance, then wear resistance is improved, but device complexity increases

Engineering Contradiction:
Improvewear resistanceVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The WFF surface layer has a porous structure composed of wood fibres and binder that allows it to function as both a protective layer and an aesthetic surface. The porous nature provides pathways for the sub-layer to permeate through, creating decorative effects while maintaining protection. This eliminates the need for separate protective coatings, reducing device complexity while maintaining wear resistance.

Inventive Principle:
Principle #31Porous materials
