Decorative Sheet Surface Structure for Touch and Gloss Contrast
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing decorative sheets struggle to balance both touch feeling and designability, particularly when incorporating a protrusion layer for gloss difference, limiting material selection freedom.
Innovation Solution
A decorative sheet design featuring a base material layer, partially provided protrusion layer, and a first resin layer containing a matting agent, with the protrusion layer comprising particles, which provides an irregular surface texture for enhanced touch feeling and designability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a protrusion layer is partially provided on a layer that imparts a gloss difference to achieve touch feeling, then the touch feeling is improved, but the degree of freedom in material selection decreases due to the need to match gloss levels
Solution Approach 1:
The patent extracts the gloss-differentiating function from the protrusion layer by removing the protrusion layer entirely and replacing it with a pattern layer that provides only the visual gloss difference. This allows the touch-feeling layer to be independently selected without gloss matching constraints, thereby resolving the contradiction between touch feeling and material selection freedom.
Solution Approach 2:
The patent segments the decorative sheet into distinct functional layers: a pattern layer for visual gloss difference and a separate touch-feeling layer for tactile properties. This segmentation allows each layer to be optimized independently for its specific function, enabling free material selection for the touch-feeling layer without being constrained by gloss matching requirements.
2Adaptability or versatility
If multiple layers are added to achieve both gloss difference and touch feeling, then the designability is improved, but the structural complexity increases
Solution Approach 1:
The patent merges the pattern layer and touch-feeling layer into a single integrated layer structure where the touch-feeling layer is formed directly on the pattern layer. This merging maintains the functional benefits of both gloss difference and touch feeling while reducing the overall structural complexity compared to using completely separate, independently laminated layers.
