Solution Overview
Problem
The challenge is to ensure seamless 5G mobile communication in head-mounted display devices by addressing the issue of shaded regions where the antenna module's beam coverage is inadequate, leading to reduced service data transmission and reception efficiency.
Innovation Solution
The electronic device incorporates an antenna module with a wireless circuit layer, heat radiating layer, and absorption layer, featuring a plurality of dipole antenna elements and switches to dynamically connect with the best-performing antenna groups based on signal quality, ensuring comprehensive beam coverage and stable communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the antenna module is disposed in a specified region to suppress radio wave interference, then communication efficiency is improved, but shaded regions are created where beam coverage is inadequate
Solution Approach 1:
The antenna module is divided into multiple antenna elements (first antenna element, second antenna element, third antenna element, fourth antenna element) that can be independently controlled. This segmentation allows the system to activate specific antenna elements based on the external device's orientation, thereby covering shaded regions while maintaining communication efficiency.
Solution Approach 2:
The antenna module dynamically adjusts which antenna elements are activated based on the determined orientation of the external device. The processor controls the antenna elements to operate in directions corresponding to the external device's orientation, ensuring continuous coverage as the device moves and rotates.
2Reliability
If the antenna module faces a specific direction, then signal transmission in that direction is optimized, but shaded regions appear when the external device moves
Solution Approach 1:
The processor determines the orientation of the external device (using sensors or other detection mechanisms) and uses this information to control which antenna elements are activated. This feedback loop ensures the antenna module adapts to the external device's movement and maintains optimal signal transmission quality.
Solution Approach 2:
The system dynamically switches between different antenna elements based on real-time orientation data. When the external device moves or rotates, the processor identifies the new orientation and activates the appropriate antenna elements to maintain coverage, making the system adaptable to continuous movement.
3Area of stationary object
If multiple antenna elements are included to cover shaded regions, then beam coverage is improved, but device complexity increases
Solution Approach 1:
The antenna module uses multiple discrete antenna elements that can be independently controlled. This segmentation allows the system to achieve comprehensive coverage by activating only the necessary elements based on orientation, rather than requiring a complex continuously-variable antenna system.
Solution Approach 2:
Each antenna element is designed to serve multiple purposes: they can transmit and receive signals in different directions, and different combinations of elements can be activated depending on the external device's orientation. This multi-functionality reduces the need for separate specialized components.
