Movable Shield Member for Antenna Interference in Rotating Electronic Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity of electronic device structures arises from the need for multiple antenna assemblies to accommodate different operating states, leading to increased complexity and potential interference between the device body and antenna performance.
Innovation Solution
An electronic device design featuring a base, connection device, body, antenna assembly, and shield member, where the shield member moves between a non-overlapping and shielding state to prevent interference between the body and antenna assembly, allowing for a single antenna assembly and simpler structure, with the shield member sliding or rotating to adjust its position based on the body's operating state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple antenna assemblies are arranged to accommodate different operating states, then the electronic device can maintain antenna performance in all states, but the device structure becomes complex
Solution Approach 1:
The patent merges the functions of multiple antenna assemblies into a single antenna assembly by introducing a shield member that can be dynamically positioned. Instead of having separate antennas for different operating states, one antenna assembly配合with a movable shield member handles all states, reducing structural complexity while maintaining antenna performance reliability.
Solution Approach 2:
The shield member is designed to be movable between different positions (shielding position and non-shielding position) based on the operating state. This dynamic adjustment allows a single antenna assembly to serve multiple purposes, eliminating the need for multiple fixed antenna assemblies and simplifying the overall structure.
2Reliability
If multiple antenna assemblies are arranged for different operating states, then antenna performance is maintained, but the number of components increases
Solution Approach 1:
The patent combines the functionality of multiple antenna assemblies into one by using a shield member that selectively shields or unshields the antenna based on operating state. This reduces the quantity of components from multiple antenna assemblies to a single antenna assembly plus a shield member.
Solution Approach 2:
The single antenna assembly is designed to be universal across different operating states, with the shield member enabling it to perform different functions (shielded and unshielded modes) depending on the operating state, replacing the need for multiple specialized antenna assemblies.
3Device complexity
If a single antenna assembly is used, then the structure is simplified, but the antenna may be affected by the device body in certain operating states
Solution Approach 1:
The shield member acts as an intermediary between the antenna assembly and the device body. When the device body may interfere with antenna performance, the shield member is positioned to shield the antenna from the body's interference. When interference is not an issue, the shield member is retracted, allowing direct operation. This mediator resolves the conflict between simplified structure and reliable performance.
Solution Approach 2:
The shield member is positioned in advance to prevent potential interference from the device body before it can affect antenna performance. By proactively shielding the antenna when the device body enters positions that could cause interference, the system maintains antenna performance reliability while using a single simplified antenna assembly.

AI summary
An electronic device includes a base, a connection device, a body, an antenna assembly, and a shield member. The body rotates to a first operating state and a second operating state relative to the base through the connection device. The shield member moves in the base to a shielding state and a non-overlapping state. When the body is in the first operating state, the body is not overlapping with the antenna assembly in a first direction, the shield member is in the non-overlapping state, and the shield member is not overlapping with the antenna assembly in the first direction. When the body is in the second operating state, the body overlaps at least a portion of the antenna assembly in the first direction, the shield member is in the shielding state, and the shield member shields between the antenna assembly and the body.
