Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the system voltage is increased to improve power transmission efficiency, then the power losses are reduced, but the risk of battery degradation increases
Solution Approach 1:
A DC-DC converter is introduced as an intermediary device between the power supply unit and the radio network node. This converter dynamically adjusts voltage levels, allowing the system to operate at higher voltages for efficient power transmission while protecting the battery from excessive voltage that would cause degradation. The converter acts as a buffer that decouples the high-voltage power transmission from the battery's voltage constraints.
Solution Approach 2:
The system implements dynamic voltage control through the DC-DC converter, which continuously adjusts the voltage output based on real-time conditions. The converter can switch between different voltage levels (e.g., 48V, 60V, 80V) and adjust current distribution to multiple outputs, enabling the system to optimize power transmission efficiency while protecting the battery from sustained high-voltage stress that would accelerate degradation.
2Power
If additional power units are added to support 5G radio units, then the power capacity is increased, but the device complexity increases
Solution Approach 1:
The DC-DC converter is designed with multi-functionality to handle various power distribution scenarios. It can simultaneously provide multiple voltage outputs (48V, 60V, 80V) to different components, support both battery and grid power inputs, and dynamically allocate power to different radio units based on demand. This universal design consolidates what would otherwise require multiple separate power management devices, reducing overall system complexity while supporting 5G power requirements.
3Use of energy by stationary object
If the output voltage is dynamically adjusted to optimize energy efficiency, then the energy efficiency is improved, but the control complexity increases
Solution Approach 1:
The system incorporates feedback mechanisms where the DC-DC converter continuously monitors power consumption, voltage levels, and load conditions. Based on this feedback, the converter automatically adjusts its output voltage and current distribution to optimize energy efficiency. The converter receives input from the control unit about power consumption patterns and dynamically modifies its operation, eliminating the need for complex manual control systems while achieving optimal energy efficiency.
