Decorative Sheet Stair-Like Embossed Surface Shine Suppression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing decorative sheets lack design enhancement due to limitations in embossing techniques, resulting in surfaces that are not visually appealing and do not effectively utilize embossing patterns for aesthetic purposes.
Innovation Solution
A decorative sheet with a concave portion on its front face, featuring a stair-like bottom surface formed by embossing, utilizing an embossing apparatus with a mold portion that includes protrusions and slits to create a design that reduces shine and enhances visual appeal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional embossing techniques are used with flat top surfaces, then the embossing process is simple, but the visual appeal and design quality are insufficient
Solution Approach 1:
The bottom surface of the embossed pattern is segmented into multiple stepped surfaces (first surface, second surface, third surface) at different depth positions. This segmentation creates a stair-like structure that enhances visual appeal while maintaining manufacturability through standard embossing processes.
Solution Approach 2:
The embossed pattern transitions from a conventional two-dimensional flat surface to a three-dimensional stepped structure with multiple depth levels. This dimensional change creates rich visual effects and shadows that significantly improve aesthetic appeal without complicating the manufacturing process.
2Ease of manufacture
If simple embossed patterns are used, then the manufacturing process is easy, but the design quality and aesthetic appeal are lacking
Solution Approach 1:
The embossed pattern is divided into multiple stepped surfaces at different depth positions, creating a complex design that appears to require high manufacturing precision but can be achieved through conventional embossing techniques by controlling the mold geometry.
Solution Approach 2:
The design quality is enhanced by changing the depth parameter of different surface regions. The first surface is at a greater depth than the second and third surfaces, creating a stair-like structure that improves aesthetic appeal while using standard embossing parameters.
3Ease of manufacture
If uniform embossed surfaces are created, then the manufacturing process is straightforward, but visual recognition of patterns is limited
Solution Approach 1:
The uniform surface is segmented into multiple stepped surfaces at different depth positions. This segmentation creates varying shadows and light reflections that significantly enhance visual recognition of the embossed patterns while maintaining process straightforwardness.
Solution Approach 2:
The transition from a uniform two-dimensional surface to a multi-level three-dimensional structure adds depth information that greatly improves visual recognition. The stepped configuration creates optical contrast that makes patterns more distinguishable.

AI summary
In a decorative sheet, a base material has a concave portion on a front face. The concave portion includes a bottom surface. The bottom surface includes a first surface, a second surface and a third surface. A depth dimension of the first surface is a first value. The depth dimension is a dimension from the front face of the base material along a thickness direction of the base material. The depth dimension of the second surface is a second value which is smaller than the first value. The third surface is a surface which is connected with the first surface at a back side of the thickness direction, and is connected with the second surface at a front side of the thickness direction.
