Engineering Contradiction Analysis
1Measurement precision
If a conventional adjustable antenna bracket is used, then the structure is simple and easy to manufacture, but the adjustment precision is insufficient leading to suboptimal signal magnitude
Solution Approach 1:
The bracket is divided into multiple functional components: a stationary bracket for rough adjustment, a movable bracket for fine adjustment, and a driver mechanism. This segmentation allows each component to specialize in a specific adjustment range, achieving high precision without requiring the entire structure to be complex.
Solution Approach 2:
The movable bracket is designed to be pivotally connected to the stationary bracket, allowing it to rotate and adjust the antenna's pointing direction dynamically. This dynamic structure enables continuous adjustment within a specific range, improving precision while maintaining reasonable structural complexity.
2Reliability
If the antenna bracket allows rough adjustment only, then the structure remains simple, but the antenna cannot be pointed precisely at the best location resulting in non-optimum signal magnitude
Solution Approach 1:
The adjustment function is segmented into two stages: rough adjustment by the stationary bracket to position the antenna near the optimal direction, and fine adjustment by the movable bracket to precisely align with the satellite. This segmentation improves signal reception quality while keeping each adjustment stage relatively simple to operate.
Solution Approach 2:
The driver mechanism acts as an intermediary between the operator and the antenna positioning system. By providing a standardized interface for adjustment, it simplifies the operation while enabling precise control through the movable bracket's rotation capability.
