Antenna Holder Counter-Support for Wind Load Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing antenna holders struggle to securely mount large-area antennas, particularly under high wind loads, due to insufficient holding forces at the mast foot.
Innovation Solution
The antenna holder design incorporates a counter-support element and support element arrangement below the mast foot, with a clamping element featuring a through-hole and a support element that increases holding force, allowing for a robust attachment mechanism that includes screw connections and welds for enhanced stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a conventional clamping element is used to fasten the antenna mast to the mounting base, then the structure remains simple, but the holding force is insufficient for large-area antennas under high wind loads
Solution Approach 1:
The clamping element is divided into two separate components: a clamping element and a counter-clamping element. These two elements work together to clamp the mounting base, with the counter-clamping element providing additional support surface area to increase holding force without requiring a single overly complex component.
Solution Approach 2:
The counter-clamping element extends in the longitudinal direction of the antenna mast, adding a dimensional aspect to the clamping mechanism. This extension provides additional contact surface area with the mounting base, increasing the holding force in the longitudinal direction where wind loads are most critical.
2Strength
If the clamping element is designed to provide sufficient holding force, then wind load capacity increases, but the risk of buckling at the mast foot increases
Solution Approach 1:
The counter-clamping element is positioned and designed to prevent buckling before it occurs by providing preliminary support at the mast foot. The support element extends below the mast foot to provide counter-support that stabilizes the mounting base against buckling forces generated by wind loads on large-area antennas.
Solution Approach 2:
The support element acts as an intermediary component between the counter-clamping element and the mounting base. It extends from the counter-clamping element to provide distributed support across the mounting base, mediating the forces and preventing concentration of stress that could lead to buckling.
3Strength
If support elements are added to increase holding force, then wind load carrying capacity improves, but manufacturing complexity increases
Solution Approach 1:
The support element and counter-clamping element are designed to be formable from a single piece of material through bending and forming operations. This merging of components into a monolithic structure eliminates the need for separate manufacturing and assembly steps, reducing manufacturing complexity while maintaining the enhanced wind load carrying capacity.
