Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual measurement method is used to obtain antenna engineering parameters, then the measurement can be performed, but the measurement error is large and data accuracy is poor
Solution Approach 1:
The patent replaces manual mechanical measurement methods with an automated electronic system that uses GPS/BeiDou satellites to obtain antenna position information and automatically calculates engineering parameters, eliminating human error and improving measurement precision
Solution Approach 2:
The antenna system performs self-measurement and self-monitoring by automatically obtaining position information from satellites and calculating its own engineering parameters, eliminating the need for external manual measurement
2Ease of operation
If remote electrical tilt apparatus is used to adjust antenna downtilt, then the adjustment can be performed remotely, but the apparatus cannot obtain antenna engineering parameters
Solution Approach 1:
The patent merges the remote adjustment function with the position information acquisition function into a single integrated system, allowing the apparatus to both remotely adjust antenna downtilt and obtain engineering parameters through the same satellite-based positioning system
Solution Approach 2:
The adjustment apparatus is designed to perform multiple functions: it can remotely adjust electrical downtilt and simultaneously obtain and process antenna position information to calculate engineering parameters, making the system universal and multi-functional
3Device complexity
If antenna engineering parameters are not updated in real time, then the system structure remains simple, but network coverage is affected due to environmental changes
Solution Approach 1:
The patent implements continuous real-time monitoring and updating of antenna engineering parameters through ongoing satellite position information acquisition, ensuring the system continuously adapts to environmental changes and maintains reliable network coverage
Solution Approach 2:
The system establishes a feedback loop where antenna position information is continuously obtained from satellites, engineering parameters are calculated in real-time, and adjustments are made based on this feedback to maintain optimal network performance despite environmental variations
