Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional site acceptance testing procedures are used, then comprehensive network testing can be performed, but the testing process becomes time-consuming and requires multiple skilled personnel
Solution Approach 1:
The system enables self-service testing where the automated drive test system independently collects RF data, processes it through algorithms, and generates diagnostic reports without requiring continuous intervention from multiple skilled personnel. The single field technician simply operates the system while the automated processes handle analysis and interpretation.
Solution Approach 2:
The patent replaces manual mechanical testing procedures with automated electronic systems. The drive test system uses automated data collection, processing algorithms, and electronic report generation to substitute for traditional manual testing methods that required multiple personnel to perform measurements and analyze results.
2Reliability
If traditional site acceptance testing procedures are used, then comprehensive network testing can be performed, but the process becomes resource-intensive requiring multiple skilled personnel
Solution Approach 1:
The drive test system is designed as a universal platform that can perform multiple testing functions through a single integrated system. It collects RF data, processes it through various algorithms, generates reports, and provides diagnostics all in one system, replacing the need for multiple specialized personnel who would traditionally perform separate testing tasks.
Solution Approach 2:
The system performs self-diagnosis and self-analysis by automatically processing collected RF data through algorithms that identify network issues, determine MIMO status, and generate diagnostic reports without requiring multiple skilled personnel to manually analyze the data.
3Productivity
If automated data processing is implemented, then testing time is reduced, but the system complexity increases
Solution Approach 1:
The system introduces an automated processing intermediary that acts as a mediator between data collection and result interpretation. The processing algorithms serve as an intermediary layer that automatically transforms raw RF data into actionable diagnostic information, reducing the need for human expertise while maintaining testing quality.
