Solution Overview
Problem
Current decorative cover plates for electronic devices lack diversity and personalization, leading to monotonous appearances that fail to meet consumer needs and reduce product competitiveness.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a simple decorative layer is attached to the cover plate surface, then the manufacturing process is simple and cost-effective, but the appearance is monotonous and lacks personalization
Solution Approach 1:
The patent changes the surface parameters of the decorative layer by forming grating grids with specific geometric structures (strip-shaped protrusions with controlled heights, widths, and spacing) to create three-dimensional light reflection effects. This transforms a flat decorative layer into one with micro-relief structures that produce woven grid patterns, achieving appearance diversity while maintaining a relatively simple manufacturing process through molding or coating techniques
Solution Approach 2:
The patent introduces a third dimension by creating raised grating grid structures on the decorative layer surface. The strip-shaped protrusions form three-dimensional patterns that reflect light differently than a flat surface, producing the illusion of woven fabric textures. This dimensional transformation enables complex visual effects without requiring multiple layered components
2Shape
If a complex texture structure is created to achieve three-dimensional woven grid pattern, then the decorative effect is enhanced, but the manufacturing complexity increases
Solution Approach 1:
The patent segments the decorative layer into multiple grating grids, each consisting of strip-shaped protrusions arranged in specific patterns. By dividing the overall texture into repeating modular units (grating grids with central points and radial arrangements), the complex three-dimensional woven effect is achieved through systematic repetition of simpler elements, reducing manufacturing complexity while maintaining visual complexity
Solution Approach 2:
The patent applies local quality variations by arranging strip-shaped protrusions with different heights, widths, and orientations in different regions of the grating grids. The protrusions closer to central points have different dimensions than those farther away, creating localized optical effects that collectively produce the overall three-dimensional woven grid pattern. This allows complex visual effects to be achieved through controlled local variations rather than uniform complex structures
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 decorative substrate enhances the aesthetic appeal by presenting a vivid three-dimensional woven grid pattern, improving the visual appeal and uniqueness of electronic device covers.
Implementation Method 1
the strip-shaped protrusions with a specific structure and arrangement in the grating structure can make the reflected light on the surface of the protrusions deviate towards the central point of the grating grid

AI summary
A decorative substrate includes a base, and a texture layer arranged on the base. A plurality of grating grids are arranged on a surface on the side of the texture layer from the base. The plurality of grating grids includes a plurality of grating structures annularly arranged around a central point. Each grating structure includes a plurality of strip-shaped protrusions, which are sequentially arranged in a radius direction of a circle with the central point as its center. In the grating grids, each strip-shaped protrusion includes a first surface close to the central point, and a second surface away from the central point. The first surface and the second surface are connected to a third surface of the strip-shaped protrusion. An included angle formed by the first surface and the third surface is less than or equal to an included angle formed by the second surface and the third surface.
