Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing antenna adjustment methods, such as universal joints and three-axis rotation schemes, fail to provide sufficient fixing capability and are cumbersome for outdoor use, especially under varying weather conditions and in high places during assembly of satellite and LTE antennas.
Innovation Solution
An antenna support device with a support arm, holder, and connecting members that allow for rotatable adjustment around two distinct axes, enabling quick and accurate positioning of the antenna via simple rotation operations, ensuring stability and ease of assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a universal joint is used for connection between antenna and holder, then the antenna can be adjusted to different directions, but the fixing capability is insufficient and the antenna cannot maintain desired position under external force
Solution Approach 1:
The patent employs a two-axis rotation mechanism where the first connecting member rotates around a first axis and the second connecting member rotates around a second axis. This dynamic structure allows the antenna to be adjusted to different directions while maintaining stable positioning through sequential rotation and locking at desired orientations, resolving the contradiction between adjustability and fixing capability.
2Measurement precision
If a three-axis rotation scheme is used for adjusting the antenna, then the antenna can be positioned accurately, but the assembly process becomes complicated
Solution Approach 1:
The patent divides the positioning function into two separate rotation stages: first connecting member for initial positioning around a first axis, and second connecting member for fine adjustment around a second axis. This segmentation simplifies the assembly process compared to a three-axis scheme while maintaining sufficient positioning accuracy for antenna installation.
3Adaptability or versatility
If the antenna components are assembled in the field at high places, then transport convenience is improved, but the assembly process becomes difficult with complicated adjustment methods
Solution Approach 1:
The two-axis rotation mechanism enables simple sequential adjustment operations that can be easily performed by workers in field conditions at high places. The first connecting member provides coarse adjustment and the second connecting member provides fine tuning, making the assembly process straightforward and suitable for field installation without requiring complex adjustment procedures.
