Antenna Positioning for Tablet Mode Radiation Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When a tablet PC with an antenna for radiating electromagnetic waves is used in tablet mode, the antenna may be located near the user's body, potentially influencing human health, and existing technologies lack effective methods to control electromagnetic wave radiation in response to changing usage positions and image display directions.
Innovation Solution
The tablet PC incorporates a system with antennas mounted at different angles and wireless LAN controllers, utilizing a power management and control system that adjusts electromagnetic wave transmission based on the device's usage mode and image orientation to ensure compliance with safety standards by reducing or stopping radiation when the antenna is positioned near the user's body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the antenna is mounted on the display unit for radio communication, then wireless communication functionality is improved, but electromagnetic wave radiation near the user's body occurs when used in tablet mode
Solution Approach 1:
The patent applies dynamics by making the antenna movable rather than fixed. The antenna can change its position along the display unit's surface based on the detected image display direction. When the display is in tablet mode with the image oriented vertically, the antenna automatically repositions to avoid being near the user's body, thus dynamically adapting to different usage scenarios to reduce electromagnetic wave exposure while maintaining wireless communication functionality.
Solution Approach 2:
The patent changes the physical position parameter of the antenna based on the image display direction. By detecting the orientation of the display (landscape or portrait mode) and adjusting the antenna's location accordingly, the system modifies its physical configuration to ensure that in tablet mode with vertical display orientation, the antenna is positioned away from the user's body, thereby reducing electromagnetic wave radiation to safe levels.
2Device complexity
If the antenna position is fixed on the display unit, then device structure is simplified, but the antenna cannot adapt to different usage positions and image display directions
Solution Approach 1:
The patent transforms the static antenna mounting into a dynamic system. The antenna is capable of moving along the display unit's surface and can be repositioned based on the detected image display direction. This dynamic adjustment mechanism allows the antenna to adapt to different usage scenarios (tablet mode vs. laptop mode) and display orientations (vertical vs. horizontal) without significantly complicating the overall device structure.
Solution Approach 2:
The patent implements a feedback mechanism where the system detects the image display direction (through sensors or software detection of display orientation) and uses this information to automatically adjust the antenna's position. The detection result feeds back to the antenna positioning mechanism, creating a closed-loop control system that ensures the antenna is always in the optimal position relative to the user's body, thereby achieving adaptability through an intelligent control system.
