Solution Overview

Problem

Existing decorative panels with beveled edges are costly to produce, require high manufacturing accuracy, and are prone to staining and damage, with visible color differences between the bevel and top surface.

Innovation Solution

A decorative panel design featuring a chamfered edge with a coating layer that seamlessly covers both the top surface and chamfer, providing protection and consistent gloss level, applied in a single manufacturing step, and optionally includes a wear layer to prevent staining and enhance durability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Shape

If digital printing is used to decorate the bevel surface, then the visual effect is enhanced, but the production cost increases and manufacturing accuracy requirements become very high

Engineering Contradiction:
Improvevisual effect of bevel surfaceVSAvoidproduction cost and manufacturing accuracy
Core Design Contradiction:
ShapeVSEase of manufacture

Solution Approach 1:

The patent merges the decoration process with the coating application by incorporating pigments directly into the coating layer that is applied to both the top surface and bevel surface. This eliminates the need for separate digital printing operations and reduces manufacturing complexity while achieving consistent visual appearance across all surfaces.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent applies the coating layer with integrated pigments to the bevel surface during the initial coating process, before any potential staining or damage can occur. This preliminary protective and decorative coating eliminates the need for subsequent expensive digital printing operations and provides immediate protection against staining.

Inventive Principle:
Principle #10Preliminary action

2Shape

If the bevel surface is decorated separately, then the aesthetic appearance is improved, but color differences between the bevel and top surface become visible

Engineering Contradiction:
Improveaesthetic appearanceVSAvoidcolor consistency
Core Design Contradiction:
ShapeVSManufacturing precision

Solution Approach 1:

The patent combines the decoration of the top surface and bevel surface into a single coating application process. The coating layer containing pigments is applied simultaneously to both surfaces, ensuring uniform color and pattern across all visible areas, thereby eliminating color differences that would result from separate decoration processes.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent achieves homogeneity in appearance by using a single coating layer with integrated pigments that covers both the top surface and bevel surface uniformly. This ensures that the color, gloss level, and overall aesthetic appearance are consistent across all surfaces, eliminating the color mismatches that occur with separate decoration methods.

Inventive Principle:
Principle #33Homogeneity

3Ease of manufacture

If the chamfer is left unprotected, then the manufacturing process is simpler, but the chamfer becomes prone to damage and staining

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoidresistance to damage and staining
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The patent combines the protection of the top surface and chamfer into a single coating application step. The coating layer is applied to both surfaces simultaneously, providing comprehensive protection against damage and staining while maintaining manufacturing efficiency. This eliminates the need for separate protection processes for the chamfer.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent applies the protective coating layer to the chamfer surface during the initial coating process, before any staining or damage can occur. This preliminary protection ensures that the chamfer is resistant to staining and damage from the outset, eliminating the need for subsequent protective treatments.

Inventive Principle:
Principle #10Preliminary action

4Reliability

If multiple separate coating steps are used for the top surface and chamfer, then each surface can be optimized, but the manufacturing process becomes more complex and time-consuming

Engineering Contradiction:
Improvesurface optimizationVSAvoidmanufacturing efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent merges the coating of the top surface and chamfer into a single application process. The coating layer is applied simultaneously to both surfaces in one operation, maintaining consistent quality and protection while significantly improving manufacturing efficiency and reducing production time compared to multiple separate coating steps.

Inventive Principle:
Principle #5Merging (Combining)
