Solution Overview
Problem
Existing methods for manufacturing textured surfaces are costly, time-consuming, inefficient, and limit custom textures, making them complex and less versatile.
Innovation Solution
A method involving a thermally stable sheet where a three-dimensional textured pattern is printed and cured, then applied to a fiberglass sheet to create a negative texture, which is pressed into a decorative laminate, allowing for efficient production of varied textures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If steel plates with desired pattern are fabricated and/or purchased to produce textured surfaces, then the textured surface can be manufactured, but the process becomes costly and time-consuming
Solution Approach 1:
The patent applies preliminary action by pre-forming a negative texture on a release sheet before the actual manufacturing process. This negative texture is created in advance and then used to efficiently produce the desired positive texture on the final product, eliminating the need for time-consuming steel plate fabrication while maintaining manufacturing precision
Solution Approach 2:
The patent uses copying by creating a negative impression or mold of the desired texture pattern on a release sheet. This negative copy is then used to generate the positive texture on the final product through a secondary forming process, significantly reducing the time and cost associated with creating the actual textured surface
2Manufacturing precision
If steel plates with desired pattern are used to manufacture textured surfaces, then the textured surface can be produced, but the process becomes complex
Solution Approach 1:
The patent simplifies the manufacturing process by performing preliminary preparation of the release sheet with a negative texture. This pre-prepared release sheet then serves as a ready-to-use tool, eliminating the need for complex steel plate fabrication equipment and reducing overall process complexity while maintaining manufacturing precision
Solution Approach 2:
The patent reduces device complexity by using a simple negative copy or mold on a release sheet instead of requiring complex steel plate fabrication equipment. The copying process allows the desired texture to be transferred through a simple forming operation rather than requiring sophisticated manufacturing machinery
3Manufacturing precision
If steel plates with desired pattern are used to manufacture textured surfaces, then the textured surface can be produced, but custom textures are limited
Solution Approach 1:
The patent applies dynamics by making the release sheet with negative texture adaptable and reconfigurable. Unlike fixed steel plates, the release sheet can be easily modified or replaced to create different negative textures, allowing the same manufacturing process to produce a variety of custom textures while maintaining consistent manufacturing precision
Solution Approach 2:
The patent enables texture design flexibility by allowing changes in the negative texture parameters on the release sheet. Different negative patterns, depths, and configurations can be created on the release sheet without changing the fundamental manufacturing process, enabling versatile custom texture production while maintaining high manufacturing precision
4Manufacturing precision
If existing methods are used to manufacture textured surfaces, then the textured surface can be produced, but the process is inefficient
Solution Approach 1:
The patent improves manufacturing efficiency by performing preliminary preparation of the release sheet with the negative texture in advance. This pre-prepared release sheet can then be used repeatedly or quickly replaced to produce multiple textured surfaces, significantly increasing productivity while maintaining consistent manufacturing precision across all produced parts

AI summary
One embodiment of a method of manufacturing a textured surface may include providing a first thermally stable sheet, printing a pattern of material on the first sheet to form a three-dimensional textured surface, and curing the material, then using said first sheet to impart negative texture into Tedlar faced epoxy composite blanket, which is in turn used to impart texture into a decorative laminate.
