Luneberg Lens Feed Positioning With Motorized Screw Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional Luneberg lens antennas require manual and labor-intensive adjustments of the feed's tilt angle, which is time-consuming and error-prone, especially in adverse weather conditions, and existing electrically adjustable solutions lack stability and convenience in assembly.
Innovation Solution
A Luneberg lens antenna with a position-electrically adjustable feed featuring a reflecting plate, a motor, guide rails, sliding blocks, and a screw mechanism that allows for precise and stable adjustment of the feed's position relative to the Luneberg lens, enabling convenient assembly and low production costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual adjustment of feed tilt angle is used, then operators can adjust the antenna position, but it is time-consuming and labor-intensive
Solution Approach 1:
The patent replaces the manual mechanical adjustment system with an electrically driven positioning mechanism. A driving assembly including a motor, transmission mechanism, and driving rod enables automated electrical adjustment of the feed position, eliminating the need for operators to manually climb towers and adjust clamps, thus resolving the contradiction between ease of operation and time consumption.
2Ease of operation
If manual adjustment is performed in bad weather, then the antenna can be adjusted, but operation difficulty increases
Solution Approach 1:
The electrically driven positioning mechanism allows operators to adjust the feed position from ground level or remotely, eliminating the need to climb towers in adverse weather conditions. The motor-driven system provides controlled adjustment without exposing operators to wind, snow, or other harmful environmental factors.
3Ease of operation
If manual adjustment is used, then the antenna position can be changed, but large error is introduced
Solution Approach 1:
The electrically driven positioning mechanism provides precise control over feed position adjustment through motor control and transmission mechanisms. This eliminates the large positioning errors inherent in manual adjustment, achieving accurate beam pointing while maintaining ease of operation through electrical control.
4Adaptability or versatility
If hinged connection is used for swinging rod, then the swinging rack can swing, but assembly convenience is reduced
Solution Approach 1:
The patent replaces the hinged connection mechanism with an electrically driven linear positioning system. The driving rod moves the feed assembly along a guide rail or track in a straight line, eliminating the need for hinged connections and swinging motions. This simplifies the assembly process while maintaining the ability to adjust the feed position effectively.
