Engineering Contradiction Analysis
1Power
If higher current is drawn to support remote equipment power demands, then power delivery capability is improved, but cable overheating and safety standard compliance deteriorate
Solution Approach 1:
The system dynamically changes the voltage parameter in real-time based on measured cable conditions. The processor adjusts the voltage output from the boosting circuit according to the measured current and temperature, optimizing power delivery while preventing cable overheating by operating within safe current thresholds.
Solution Approach 2:
The system implements a closed-loop feedback mechanism where the measuring circuit continuously monitors cable current and temperature, and the processor uses this feedback to dynamically adjust the voltage output. This feedback loop ensures the cable operates within safe parameters while maximizing power delivery capability.
2Power
If higher current is drawn to meet power demands, then power delivery is improved, but cable efficiency deteriorates due to increased resistance
Solution Approach 1:
The system dynamically changes the voltage parameter to optimize the current flow through the cable. By adjusting voltage based on measured conditions, the system maintains operation in a more efficient range, reducing resistive losses while still meeting the power demands of remote equipment.
3Length of moving object
If cable length is increased to reach remote equipment at top of tall cell towers, then coverage capability is improved, but power loss and heating increase
Solution Approach 1:
The system compensates for cable length-related losses by dynamically adjusting the voltage parameter. The processor calculates the required voltage boost based on the cable length and measured current, ensuring adequate power delivery to remote equipment at the top of tall cell towers while minimizing power loss and heating in the extended cable run.
