Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Miniaturized and lightweight electronic devices face challenges in securing installation space for antenna devices while maintaining stable performance and visibility, especially in screen display regions.
Innovation Solution
An antenna device is designed with a dielectric substrate and a mesh grid featuring transparent conducting wires, where a radiation conductor portion is electrically opened by a dummy pattern with discontinuous portions, ensuring uniform light transmittance and allowing installation in small spaces without compromising display quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If the antenna device is installed in a miniaturized electronic device, then the portability and convenience are improved, but the installation space and stable performance are compromised
Solution Approach 1:
The patent transitions the antenna from a traditional planar configuration to a three-dimensional mesh grid structure that can be integrated into the display's depth and surface area, enabling space-efficient installation in miniaturized devices while maintaining antenna performance
Solution Approach 2:
The mesh grid structure serves dual functions: it acts as both the antenna radiation element and a transparent overlay that does not interfere with display visibility, allowing the same structure to fulfill both communication and display requirements
2Area of stationary object
If the antenna device is installed in the screen display region, then the installation space is improved, but the display visibility and quality are compromised
Solution Approach 1:
The patent uses a mesh grid constructed from thin transparent conducting wires that allow light to pass through with minimal obstruction, maintaining display visibility while providing functional antenna coverage in the screen region
Solution Approach 2:
The mesh grid structure varies the density and configuration of conducting wires in different regions, optimizing both antenna performance in specific areas while maintaining high light transmittance in display-critical regions
3Ease of manufacture
If the mesh grid uses uniform conducting wires, then the manufacturing simplicity is improved, but the light transmittance uniformity and display quality are compromised
Solution Approach 1:
The patent implements varying line widths of conducting wires within the mesh grid, with different wire thicknesses in different regions to compensate for optical effects and achieve uniform light transmittance across the display area, while still using standard fabrication processes
