Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In foldable electronic devices, the proximity of antenna radiators when the device is folded leads to mutual interference, causing distortion of wireless signals and deterioration of antenna radiation performance.
Innovation Solution
The device employs a switching mechanism for the antenna groups based on its state, using a processor to recognize the folded or unfolded state and activate the appropriate antenna group to maintain optimal performance.

Engineering Contradiction Analysis
1Reliability
If the housing is made of conductive material to serve as antenna radiator, then antenna radiation performance is improved, but mutual interference occurs when the device is folded causing signal distortion
Solution Approach 1:
The antenna system is divided into multiple independent antenna groups (first antenna group and second antenna group) located on different housing structures. This segmentation allows the system to avoid mutual interference by selecting which antenna group to activate based on the device's folded or unfolded state, thereby maintaining reliable antenna radiation performance without signal distortion.
Solution Approach 2:
The antenna system dynamically switches between different antenna groups based on the device's state (folded or unfolded). This dynamic adaptation ensures that the active antenna radiators are always positioned optimally to avoid mutual interference, maintaining consistent antenna radiation performance across different device configurations.
2Adaptability or versatility
If multiple antenna radiators are used to improve wireless communication, then communication capability is enhanced, but antenna performance deteriorates when radiators come close in folded state
Solution Approach 1:
The antenna system is divided into multiple independent antenna groups (first antenna group and second antenna group) located on different housing structures. This segmentation allows the system to avoid mutual interference by selecting which antenna group to activate based on the device's folded or unfolded state, thereby maintaining reliable antenna radiation performance without signal distortion.
Solution Approach 2:
The system changes the operational parameters by switching between different antenna groups based on the device's state. When folded, one antenna group is activated while the other is deactivated, and vice versa when unfolded. This parameter change ensures optimal antenna performance across different device configurations.
3Ease of operation
If the device structure allows folding to improve portability, then ease of operation is enhanced, but antenna radiation performance becomes unstable
Solution Approach 1:
The antenna system dynamically switches between different antenna groups based on the device's state (folded or unfolded). This dynamic adaptation ensures that the active antenna radiators are always positioned optimally to avoid mutual interference, maintaining consistent antenna radiation performance across different device configurations.
Solution Approach 2:
The system changes the operational parameters by switching between different antenna groups based on the device's state. When folded, one antenna group is activated while the other is deactivated, and vice versa when unfolded. This parameter change ensures optimal antenna performance across different device configurations.
