Pivotable Antenna Assembly to Avoid Laptop Screen 5G Blocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The screen part of a conventional laptop computer significantly degrades the signal transmission/reception efficiency of a 5G antenna due to its blocking effect on the main signal transmission/reception direction, as 5G signals have weak penetration ability and a small transmission/reception range.
Innovation Solution
The electronic device incorporates a pivotable assembly with a rotatable antenna assembly, allowing the angle of the main signal transmission/reception surface to be adjusted, ensuring no elements block the signal path, thereby maintaining optimal signal performance.

Engineering Contradiction Analysis
1Device complexity
If the 5G antenna is disposed on the same position as the 4G antenna under the conventional laptop configuration, then the device structure is simple, but the screen part blocks signals in the main signal transmission/reception direction, significantly degrading signal transmission/reception efficiency
Solution Approach 1:
The patent applies the dynamics principle by making the antenna assembly rotatable relative to the casing through a pivotable mechanism. This allows the antenna's main signal transmission/reception surface to dynamically adjust its angle, enabling it to rotate away from the screen's blocking path and maintain optimal signal reception without requiring a completely separate fixed antenna structure.
Solution Approach 2:
The patent resolves the spatial conflict between the screen and antenna by introducing rotational freedom in a different dimension. Instead of only adjusting the antenna's position in the horizontal or vertical plane, the antenna assembly can rotate around an axis perpendicular to the screen, creating a new dimensional degree of freedom that allows signal transmission in directions not blocked by the screen.
2Reliability
If the antenna assembly is made rotatable to avoid signal blocking, then signal transmission/reception efficiency is maintained, but the device structure becomes more complex
Solution Approach 1:
The patent merges the antenna assembly with the existing pivotable screen assembly structure. The antenna assembly is integrated into the screen assembly such that it shares the same pivot mechanism and mounting structure, allowing the antenna to rotate together with the screen. This combining approach avoids creating a separate complex rotation mechanism solely for the antenna.
Solution Approach 2:
The pivotable assembly structure serves multiple functions: it enables both the screen to pivot for viewing angle adjustment and the antenna to rotate for signal optimization. This multi-functionality reduces the need for separate mechanisms, as the same structural elements serve both the display and communication functions simultaneously.
