Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pressing tools for producing material boards with decorative layers require environmentally harmful chromium coatings and are costly, lacking in reproducibility and flexibility for achieving different degrees of gloss and structural detail.
Innovation Solution
A pressing tool with a base structure and at least two ceramic layers, one full-surface and one partial-surface, applied using a surface magnetron sputter coating system, allowing for different degrees of gloss and structural complexity without chromium, enabling cost-effective and environmentally friendly production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If chromium layers with masking processes are used to create structured pressing surfaces with different gloss degrees, then the desired surface structure and gloss variation are achieved, but the manufacturing process becomes environmentally harmful and complex
Solution Approach 1:
The patent applies composite materials by combining multiple ceramic layers (first ceramic layer and second ceramic layer) with different gloss degrees to form the pressing surface. This replaces the chromium-based coating system with an environmentally friendly ceramic composite that achieves the same functional result of creating varied gloss surfaces without requiring complex masking processes
Solution Approach 2:
The patent changes the material parameter from chromium-based coatings to ceramic materials, and varies the gloss degree parameter by using different ceramic compositions or treatments in the first and second ceramic layers. This allows achieving different gloss levels through material composition rather than through complex masking and coating processes
2Manufacturing precision
If chromium layers and multiple masking steps are used to produce structured surfaces, then the pressing tool achieves the required surface properties, but the production process becomes environmentally harmful
Solution Approach 1:
The patent uses composite ceramic layers to replace chromium-based coatings. The first ceramic layer and second ceramic layer form an environmentally friendly composite structure that achieves the desired gloss variation without releasing harmful chromium compounds during manufacturing or use
Solution Approach 2:
The patent changes the material parameter from toxic chromium to non-toxic ceramic materials, fundamentally altering the environmental impact parameter while maintaining the functional parameter of gloss degree control through compositional variation of the ceramic layers
3Productivity
If traditional pressing tools are used to produce material boards with structured surfaces, then the basic pressing function is achieved, but the reproduction accuracy of natural surfaces is insufficient
Solution Approach 1:
The patent uses composite ceramic layers with different gloss degrees to accurately reproduce the complex optical properties of natural surfaces. The first ceramic layer and second ceramic layer work together to create multi-dimensional surface characteristics that closely mimic natural materials like wood or stone, significantly improving reproduction accuracy
Solution Approach 2:
The patent applies local quality by giving different regions of the pressing surface different gloss degrees through the first and second ceramic layers. This allows different areas to replicate specific local characteristics of natural surfaces, enhancing the overall fidelity of the reproduction while maintaining production efficiency

AI summary
A pressing tool for producing a workpiece having a pressing surface. The pressing tool comprises a base structure and at least two ceramic layers which are arranged on the surface and form the pressing surface, of which a first ceramic layer has a first degree of gloss, and a second ceramic layer has a second degree of gloss, which differs from the first degree of gloss of the first ceramic layer.
