Planar Antenna Support with Gravity-Aligned Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Planar antenna apparatuses used in outdoor communication systems, such as VSAT systems, face instability due to wind and other environmental factors, which can cause them to incline and lose alignment, affecting communication quality.
Innovation Solution
The design includes a support structure with three or more rotatable support legs and movable units that allow the antenna unit to be adjusted to a minimum use angle, aligning the center of gravity of the entire apparatus with the center of gravity of a polygon formed by the support legs' grounding points, ensuring stability against wind-induced inclines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the planar antenna apparatus is installed outdoors with a simple support structure, then the installation is easy and the structure is simple, but the apparatus becomes unstable under wind influence and inclines
Solution Approach 1:
The support structure is divided into multiple independent support legs (at least three) that are segmented and distributed around the installation surface. Each support leg can be independently positioned to form a stable polygonal base, allowing easy installation while providing collective stability against wind forces.
Solution Approach 2:
The support legs extend in different directions from the installation surface, creating a three-dimensional stable base. By distributing support points in multiple spatial dimensions and forming a polygonal configuration, the structure achieves stability without complex mechanical components, maintaining installation simplicity.
2Reliability
If the antenna unit is positioned at a higher elevation angle for optimal communication, then the communication quality improves, but the apparatus becomes more susceptible to wind-induced inclining
Solution Approach 1:
The center of gravity of the entire apparatus is strategically positioned directly above the center of gravity of the polygon formed by the support legs' grounding points. This creates a gravitational counterbalance that resists wind-induced tilting, allowing the antenna to maintain higher elevation angles for better communication while remaining stable against wind forces.
Solution Approach 2:
By aligning the apparatus center of gravity with the polygon center of gravity, the system achieves a state of gravitational equipotential stability. This configuration minimizes the torque effect of wind forces, allowing the antenna to maintain its communication-optimized elevation angle without being excessively affected by wind-induced inclining.
