Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing apparatuses for treating plate-shaped workpieces, such as those in the furniture industry, are limited in achieving a high-quality, cost-efficient, and customizable appearance, particularly in applying coatings and adjusting gloss and haptic properties on wood or wood materials.
Innovation Solution
An integrated apparatus comprising a coating device, lacquer application device, structuring device, printing device, machining unit, cleaning device, plasma treatment device, and adhesion promoter application device, which allows for the application of strip-shaped coating materials, lacquer application, surface structuring, printing, and machining in a single operation, enabling high gloss to dull matte finishes and individual design options.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple separate devices are used for coating, lacquer application, and surface structuring, then each device can be optimized for its specific function, but the overall process complexity increases and production time increases
Solution Approach 1:
The patent combines coating device, lacquer application device, and structuring device into a single integrated apparatus. The coating device applies coating material, the lacquer application device applies lacquer to the coating material, and the structuring device structures the lacquer surface - all in one continuous process without transferring the workpiece between separate devices.
Solution Approach 2:
The integrated apparatus performs multiple functions (coating application, lacquer application, and surface structuring) within a single device system. This multi-functional approach allows the apparatus to handle the complete surface treatment process, reducing the need for multiple specialized devices while maintaining high surface quality.
2Reliability
If multiple separate devices are used for coating, lacquer application, and surface structuring, then each device can be optimized for its specific function, but the production time increases
Solution Approach 1:
The patent combines coating device, lacquer application device, and structuring device into a single integrated apparatus. The coating device applies coating material, the lacquer application device applies lacquer to the coating material, and the structuring device structures the lacquer surface - all in one continuous process without transferring the workpiece between separate devices.
Solution Approach 2:
The integrated apparatus enables continuous processing where the workpiece moves through coating application, lacquer application, and surface structuring in a single uninterrupted flow. This eliminates idle time between operations and maintains continuous productive action throughout the surface treatment process.
3Adaptability or versatility
If traditional coating methods are used, then the process is simple, but the ability to achieve high gloss to dull matte finishes and individual designs is limited
Solution Approach 1:
The structuring device enables dynamic adjustment of surface properties during the lacquer application process. By controlling the structuring parameters, the apparatus can achieve varying gloss levels from high gloss to dull matte finishes on the same workpiece, allowing for individual design customization.
Solution Approach 2:
The apparatus applies different treatments to different areas of the workpiece surface. The coating device, lacquer application device, and structuring device can be positioned and configured to apply specific treatments to specific zones, enabling multi-zone designs with different gloss levels and haptic properties.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables high-quality, cost-efficient, and customizable surface treatment of workpieces with precise control over gloss and haptic properties, allowing for individual design and high throughput without the need for realignment, improving reproducibility and surface quality.
Implementation Method 1
The lacquer application device may comprise a nozzle for spray application
Implementation Method 2
The lacquer application device may comprise an inkjet print head
Implementation Method 3
The action on the lacquer surface results in polymerization of the lacquer so that the surface is, so to speak, folded
Implementation Method 4
The structuring device may be, or include, an excimer lamp
Implementation Method 5
a gloss value can also be adjusted precisely by means of an infrared lamp
Implementation Method 6
a gloss value can also be adjusted precisely by means of an infrared lamp, a microwave source and/or an LED source
