Solution Overview

Problem

Existing methods for manufacturing coated panels with decorative top layers struggle with achieving complex and pronounced structures, particularly those with acute angles and deep features, due to limitations in accuracy, flexibility, and the unnatural appearance caused by rounded portions.

Innovation Solution

A method involving the use of multiple print layers on top of each other to create protrusions, allowing for varied depth resolution and structure complexity, with the option of using digitally controlled inkjet printing units and a transparent or translucent layer to enhance visibility and durability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If a single print layer is used to form structures on the substrate, then the manufacturing process is simple and economical, but the structures lack depth, complexity, and pronounced features

Engineering Contradiction:
Improvestructure depth and complexityVSAvoidnumber of print layers
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent applies dimensionality change by transitioning from a single two-dimensional print layer to multiple stacked print layers. This allows the creation of three-dimensional protrusions with varying heights and complex geometries. Each print layer contributes to building up the structure vertically, enabling acute angles and deep features that cannot be achieved with a single layer, while maintaining alignment through registration marks and templates.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Shape

If traditional printing methods are used to create structures, then the process is economical, but structures with acute angles and deep features cannot be realized due to rounded portions

Engineering Contradiction:
Improveacute angles and deep featuresVSAvoidaccuracy of structure correspondence
Core Design Contradiction:
ShapeVSManufacturing precision

Solution Approach 1:

The patent segments the structure formation process into multiple discrete print layers, each contributing a portion of the final three-dimensional structure. This segmentation allows each layer to be printed with precise geometric control, avoiding the rounded portions that occur in single-layer printing. The stacked layers can be designed with acute angles and deep features, and their cumulative effect creates the desired complex shape with high manufacturing precision through proper registration.

Inventive Principle:
Principle #1Segmentation

3Manufacturing precision

If multiple print layers are stacked to create complex structures, then depth resolution and structure complexity are enhanced, but the alignment accuracy between layers becomes more difficult to maintain

Engineering Contradiction:
Improvedepth resolutionVSAvoidalignment and registration system
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent implements preliminary action by incorporating registration marks and alignment features into each print layer before the actual structure printing. These preliminary elements are used to establish precise registration between layers, ensuring that the complex multi-layer structure maintains accurate alignment. The template-based approach allows depth resolution to be enhanced through multiple layers while the preliminary alignment features prevent registration errors from compromising the final structure.

Inventive Principle:
Principle #10Preliminary action

AI summary

A coated panel may include a substrate and a decorative top layer provided on the substrate. A method for manufacturing the panel may involve forming at least a portion of the top layer by printing on the substrate to provide a structure on the substrate. The structure may include protrusions formed by two or more prints provided on top of each other.
