Engineering Contradiction Analysis
1Measurement precision
If manual check methods are used to determine power supply relationships, then operators can identify the connection between power supply units and radio frequency units, but the process becomes time-consuming and labor-intensive
Solution Approach 1:
The system enables automatic determination of power supply relationships through self-service mechanisms. The base station autonomously controls load variations on carriers and monitors power consumption changes without external intervention, eliminating the need for manual field checks and significantly reducing determination time while maintaining accuracy.
Solution Approach 2:
The patent replaces manual mechanical inspection methods with an automated electronic measurement system. By substituting human operators with automated load control and power consumption monitoring mechanisms, the system achieves faster and more consistent determination of power supply relationships.

Solution Approach 1:
The system enables automatic determination of power supply relationships through self-service mechanisms. The base station autonomously controls load variations on carriers and monitors power consumption changes without external intervention, eliminating the need for manual field checks and significantly reducing determination time while maintaining accuracy.
3Extent of automation
If automated load control is implemented to determine power supply relationships, then manual participation is eliminated and time is saved, but the system must coordinate load changes across multiple carriers
Solution Approach 1:
The patent segments the determination process into distinct phases: selecting a target carrier, controlling its load to vary, monitoring power consumption changes, and identifying the corresponding power supply unit. This segmentation simplifies the overall automation process by breaking down complex coordination tasks into manageable steps that can be executed systematically.
