Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The radiation performance of antennas in electronic devices with flexible displays is degraded due to their proximity to conductive materials in the housing, affecting wireless communication capabilities.
Innovation Solution
Forming a hole in the second housing between the antenna and the flexible display to create a spacing gap, improving antenna radiation performance by reducing interference from conductive materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the antenna is disposed adjacent to the ground having conductive material (second housing or flexible display), then the device structure is compact and simple, but the radiation performance of the antenna is degraded
Solution Approach 1:
A hole is formed in the second housing to create a spacing gap between the antenna and the conductive ground. This hole acts as an intermediary space that electrically isolates the antenna from the conductive material, improving radiation performance while maintaining a relatively simple device structure without requiring additional shielding components
Solution Approach 2:
The hole is specifically positioned at a location where it does not interfere with the overall structural integrity of the device. By creating a localized opening only in the necessary area, the antenna's radiation performance is improved while the rest of the device maintains its compact and simple structure
2Reliability
If a hole is formed in the second housing to improve antenna radiation performance, then the radiation efficiency is enhanced, but the structural integrity of the housing is compromised
Solution Approach 1:
The hole is formed at a specific location in the second housing where it creates the necessary spacing for antenna radiation while minimizing impact on overall structural integrity. The hole's position and size are optimized to provide electromagnetic isolation without compromising the housing's mechanical strength
Solution Approach 2:
The hole creates a three-dimensional spacing gap between the antenna and the conductive ground, establishing an electromagnetic isolation path in the vertical dimension while maintaining the housing's two-dimensional structural integrity in other directions
