Structured Pressing Surface for Matte Cratered Workpiece Finishes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pressing tools fail to effectively produce workpieces with a structured surface that achieves a matte appearance, particularly in regions with crater-shaped recesses, which are not adequately addressed by existing technologies.
Innovation Solution
A pressing tool with a structured pressing surface featuring peg-shaped and/or rod-shaped structures that protrude from the surface, creating crater-shaped recesses upon pressing, which absorb light to achieve a matte appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a structured pressing surface with mountain-like surface and valleys is used, then material boards with structured surfaces having multiple degrees of gloss can be produced, but the ability to create regions with matte appearance is insufficient
Solution Approach 1:
The pressing surface is divided into different regions with distinct structures: a first region with a mountain-like surface for creating glossy areas, and a second region with peg-shaped or rod-shaped protrusions for creating matte areas with crater-shaped recesses. This local differentiation allows the pressing tool to produce workpieces with multiple appearance characteristics in different zones.
2Shape
If a pressing surface with mountain-like surface is used, then structured surfaces with multiple degrees of gloss can be produced, but crater-shaped recesses for deep black or matte impression are not achieved
Solution Approach 1:
The pressing surface incorporates peg-shaped or rod-shaped protrusions that create crater-shaped recesses in the workpiece. These recesses function similarly to porous structures by trapping and absorbing light, creating regions with matte appearance or deep black impression that contrast with the glossy areas.
3Productivity
If existing pressing tools with mountain-like surface are used, then material boards can be produced, but the structured surface cannot achieve relatively matte appearance in specific regions
Solution Approach 1:
The pressing surface is segmented into functionally distinct regions: a first region with mountain-like surface structure for producing glossy areas, and a second region with peg-shaped or rod-shaped structures for producing matte areas with crater-shaped recesses. This segmentation enables simultaneous production of workpieces with both glossy and matte appearance characteristics in a single pressing operation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The structured surface of the workpiece, such as material boards, achieves a matte finish by creating crater-shaped recesses that absorb light, providing a deep black or relatively matte impression, suitable for applications like laminate flooring and furniture surfaces.
Implementation Method 1
this region absorbs at least a part of the incident light, which creates the conditions for this area to appear relatively matte

AI summary
The disclosure relates to a pressing tool which has a structured pressing surface which is provided for producing, by pressing, a workpiece having a structured surface. At least one region of the pressing surface has a peg-shaped and/or rod-shaped structure with pegs and/or rods protruding from the pressing surface. The disclosure also relates to a workpiece which comprises a structured surface. At least one region of the structured surface comprises crater-shaped recesses in the structured surface, in order to confer a relatively matte impression on this region.
