Movable Antenna Bracket for Slim Display Wireless Performance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge is to develop a slim display device with improved wireless performance, particularly in designs with minimal bezel size and thickness, where components like antennas are affected by surrounding elements.
Innovation Solution
The display device incorporates a moving bracket system with a driving unit, including a motor and rack gear, to selectively expose components like antennas in the front direction, maintaining a clean appearance while ensuring effective wireless communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the display device is designed with minimal bezel size and slim thickness, then the aesthetic appearance and modern design are improved, but the wireless performance deteriorates due to antenna interference from surrounding components
Solution Approach 1:
The antenna is implemented as a movable component that can change its position between a retracted state (when the display is off) and an extended state (when the display is on). This dynamic configuration allows the antenna to be hidden during non-use to maintain aesthetic appearance, and exposed during use to ensure optimal wireless performance without interference from surrounding components.
Solution Approach 2:
The antenna structure is divided into a movable bracket portion and a fixed housing portion. The movable bracket can be independently actuated to extend or retract the antenna relative to the housing, allowing separate control of aesthetic appearance and wireless performance requirements.
2Reliability
If components like antennas are always exposed in the front direction, then wireless performance is improved, but the aesthetic appearance deteriorates due to visible components on the bezel
Solution Approach 1:
The antenna implementation uses a movable bracket that can dynamically adjust its position based on operational requirements. When the display is off, the antenna retracts to maintain a clean aesthetic appearance. When the display is on, the antenna extends to ensure optimal wireless performance, thus resolving the contradiction between appearance and functionality.
3Shape
If the antenna is retracted to maintain clean appearance, then aesthetic appearance is improved, but wireless performance deteriorates due to limited signal transmission
Solution Approach 1:
The system dynamically adjusts the antenna position based on operational state. The movable bracket extends the antenna when the display is activated to ensure adequate wireless performance, and retracts it when the display is off to maintain aesthetic appearance. This conditional positioning resolves the contradiction between appearance and performance.
Solution Approach 2:
The antenna is pre-positioned in the retracted state during manufacturing to maintain aesthetic appearance. Before wireless communication begins (when the display turns on), the movable bracket automatically extends the antenna to the optimal position, ensuring performance is prepared in advance.
