Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If frequency spectrograph is used to analyze interference signals, then measurement precision is improved, but ease of operation deteriorates
Solution Approach 1:
The base station automatically performs interference detection and analysis by collecting interference parameters from multiple cells and generating spectrum graphics autonomously, eliminating the need for manual frequency spectrograph operations while maintaining high measurement precision
Solution Approach 2:
The patent replaces manual frequency spectrograph analysis with automated digital signal processing algorithms that collect interference parameters, calculate spectrum graphics, and identify interference sources through computational methods, substituting mechanical/manual operations with electronic automation
2Adaptability or versatility
If base stations are deployed in remote places, then adaptability is improved, but loss of time worsens
Solution Approach 1:
The network manager serves multiple base stations simultaneously through a unified interference detection system, enabling remote base stations to perform interference analysis locally while the network manager coordinates data collection across the entire network, reducing overall detection time
Solution Approach 2:
The system pre-configures interference detection parameters and thresholds in the network manager before field deployment, allowing base stations in remote locations to immediately begin interference monitoring without requiring on-site configuration, thus eliminating deployment delays
3Measurement precision
If threshold values are increased to accurately determine interference, then measurement precision is improved, but device complexity worsens
Solution Approach 1:
The patent dynamically adjusts interference detection thresholds based on signal characteristics and network conditions, using multiple parameters (interference parameters, spectrum graphics, threshold values) that are automatically optimized by the network manager to maintain high detection accuracy without manual intervention
Solution Approach 2:
The system implements feedback loops where the network manager continuously monitors interference detection results, adjusts threshold values based on observed patterns, and refines detection parameters over time, automatically optimizing precision while maintaining system simplicity through adaptive learning
4Measurement precision
If additional software is deployed to investigate interference, then measurement precision is improved, but device complexity worsens
Solution Approach 1:
The network manager integrates multiple functions (data collection, spectrum analysis, interference detection, and source identification) into a single unified software platform, eliminating the need for separate specialized software while maintaining comprehensive interference analysis capabilities
Solution Approach 2:
The patent combines interference detection, spectrum graphics generation, and source identification functions into the existing network manager system, merging multiple analytical tools into one integrated platform that reduces software complexity while preserving measurement precision
