Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing antenna alignment systems face challenges in achieving precise alignment due to their design, which often fails to securely attach to the back wall of antennas with non-flat or curved profiles, leading to inaccuracies in signal strength and bandwidth optimization.
Innovation Solution
A bracketed apparatus that conforms to the back wall of antennas, with a securing mechanism and an alignment device, allows for precise alignment by attaching to the back wall, ensuring accurate positioning and alignment reference points, lines, or planes, suitable for various antenna types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If GPS antennas are mounted to the side of the antenna below it, then the system can determine azimuth, but multipath errors are introduced reducing measurement precision
Solution Approach 1:
The alignment apparatus transitions from side-mounting GPS antennas (horizontal dimension) to top-mounting with vertical positioning. By elevating the GPS antenna to the top surface and positioning it vertically above the antenna back wall, the system changes the spatial dimension of antenna mounting, thereby eliminating multipath errors caused by side-mounting while maintaining azimuth measurement capability.
2Measurement precision
If the alignment system is mounted on top of the antenna, then multipath errors are avoided, but there can be no guarantee that the system is aligned along the correct plane
Solution Approach 1:
A rigid bracket serves as an intermediary component between the alignment system and the antenna. The bracket is attached to the top surface of the antenna and provides a stable mounting platform with reference markings that define the correct alignment plane. This intermediary structure ensures both multipath error avoidance and precise plane alignment by combining top-surface mounting with reference-based positioning.
3Ease of operation
If prior art alignment systems are used, then alignment can be performed, but small errors in azimuth alignment cause significant degradation in signal quality
Solution Approach 1:
The alignment apparatus incorporates reference markings on the bracket and corresponding reference features on the antenna that provide visual feedback during alignment. These references allow the installer to verify and adjust the alignment position, ensuring high azimuth accuracy. The feedback mechanism enables precise alignment by allowing continuous verification and adjustment against known reference points.
4Ease of operation
If the alignment system uses buttons that can be pressed with force, then operation is simplified, but the system becomes out of alignment
Solution Approach 1:
The alignment apparatus removes physical buttons and interactive controls from the alignment system. Instead, alignment is achieved through passive reference markings and visual alignment methods that do not require pressing buttons or applying force. This extraction of mechanical controls eliminates the risk of alignment disruption while maintaining ease of operation through visual reference-based alignment.
5Measurement precision
If the SPAA alignment system uses two arms bracing front and back panels, then azimuth measurement is improved, but maintaining exact parallel alignment is difficult
Solution Approach 1:
The alignment system separates the mounting function from the measurement function. The bracket provides a stable single-point mounting platform on the top surface, while the alignment references are independently positioned on the bracket. This segmentation allows the measurement references to remain stable and parallel without requiring complex multi-arm structures, simplifying both maintenance and accuracy.
