Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If power-consuming apparatuses such as TRX and PA are added to enhance bearer capability, then the base station's communication capability is improved, but electric energy consumption is greatly increased
Solution Approach 1:
The energy storage device stores electric energy in advance during periods when the base station power consumption is low, so that the stored energy can be used later when power consumption increases, avoiding the need to continuously supply high power that would deplete the grid connection
Solution Approach 2:
The system dynamically adjusts the power output parameters of the base station based on the state of the energy storage device. When the energy storage device is fully charged or not present, the base station operates at baseline power; when energy is available, it can operate at higher power levels to enhance communication capability
2Productivity
If the base station operates at high power for extended periods, then communication performance is maintained, but the energy storage device becomes insufficient and causes site breakdowns
Solution Approach 1:
The base station continuously monitors the state of the energy storage device (charged, discharging, or insufficient) and adjusts its power consumption accordingly. When the energy storage device state indicates insufficient energy, the base station automatically reduces power consumption to prevent site breakdowns
Solution Approach 2:
The base station power consumption is made dynamic rather than static. It adapts its power usage based on real-time conditions including the presence and state of the energy storage device, transitioning between baseline power mode and enhanced power mode as energy availability changes
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Reduces site breakdowns and maintains stable operation by optimizing energy usage, ensuring efficient power distribution and reducing excessive power consumption.
Implementation Method 1
adding an energy storage device. When power of a main device is lower than baseline power, that is, the baseline power output by a power supply device still has a remainder after provided for use by the main device, the energy storage device is in a charged state and stores the remaining electric energy
Implementation Method 2
When the power of the main device is greater than the baseline power, that is, the baseline power output by the power supply device is insufficient to be provided for use by the main device, the main device receives electric energy output by the power supply device and the energy storage device, that is, the energy storage device is in a discharging state and supplies power together with the power supply device

AI summary
This application disclose example electric energy control methods. When power of a main device is lower than baseline power, an energy storage device is in a charging state and stores remaining electric energy. When power of a main device is greater than the baseline power, the main device receives electric energy output by a power supply device and the energy storage device. To be specific, the energy storage device is in a discharging state and supplies power together with the power supply device to ensure operation of the main device. However, an amount of electric energy stored in the energy storage device is limited. When an amount of the electric energy of the energy storage device is insufficient, the main device is notified to decrease radio frequency power of a preset frequency band of the main device, to reduce a breakdown caused by excessively high power of the main device.
