Solution Overview

Problem

Decorative panels often exhibit shiny bevels that detract from their visual appeal, and existing solutions involving additional coatings or varnishes are costly, time-consuming, and can lead to overspray issues.

Innovation Solution

A device and method using an embossing roller with adjustable alignment and pressure to mechanically matte the bevels, incorporating embossing structures such as knurling, to reduce gloss without additional coatings.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If coating or varnishing is applied to bevels to reduce gloss, then visual appearance is improved, but production cost increases and overspray problems occur

Engineering Contradiction:

Improvegloss level of bevelVSAvoidproduction process complexity

Core Design Contradiction:

Illumination intensityVSDevice complexity

Solution Approach 1:

The patent replaces the chemical coating/varnishing process with a mechanical embossing process. An embossing roller with a structured surface mechanically presses the bevel area to create a matte effect through surface deformation, eliminating the need for additional coating materials and application equipment.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The embossing roller is integrated directly into the panel production line, allowing the bevel matting to be performed automatically during the manufacturing process itself. The panel's own structure (the bevel) serves as the target for the embossing action, combining the matting function with the existing production flow without requiring separate coating operations.

Inventive Principle:

Principle #25Self-service

2Illumination intensity

If coating agent is applied to bevels, then gloss is reduced, but production time increases due to additional processing steps

Engineering Contradiction:

Improvegloss level of bevelVSAvoidproduction speed

Core Design Contradiction:

Illumination intensityVSProductivity

Solution Approach 1:

The embossing operation is merged with the existing panel production process. The embossing roller is positioned to act on the bevel area during or immediately after the panel forming operation, combining multiple functions (panel formation and surface matting) into a single integrated process step, thereby maintaining high production speed.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The bevel matting is performed as a preliminary action during panel manufacturing, before the panels are installed or further processed. This ensures the matte effect is achieved in advance, eliminating the need for post-installation touch-ups or separate matting operations that would delay overall productivity.

Inventive Principle:

Principle #10Preliminary action

3Illumination intensity

If coating is applied to bevels, then visual appearance improves, but overspray causes optical disadvantages and panel rejection

Engineering Contradiction:

Improvegloss level of bevelVSAvoidoverspray contamination

Core Design Contradiction:

Illumination intensityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces the spray coating process with direct mechanical contact through the embossing roller. This localized mechanical action applies force only to the specific bevel area, completely eliminating overspray and the associated contamination problems that lead to panel rejection.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
