Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If x-ray production systems operate with high power consumption to achieve sufficient output power, then the output power is improved, but the power consumption from the power supply network increases
Solution Approach 1:
The backup circuit with energy storage cells is pre-charged during periods when the mains connection is stable and voltage is within normal ranges. This preliminary energy storage allows the system to draw from stored energy during high-power x-ray emission phases, reducing instantaneous power consumption from the mains network while maintaining sufficient output power.
Solution Approach 2:
The backup circuit acts as an intermediary energy buffer between the mains connection and the inverter circuit. It decouples the direct power transmission path, allowing the system to smooth out power consumption peaks by drawing from stored energy, thereby reducing the maximum power demand on the power supply network while maintaining the required output power.
2Use of energy by moving object
If the number of energy storage cells is increased to further reduce power consumption, then the power consumption is reduced, but the device complexity increases
Solution Approach 1:
The backup circuit incorporates a dynamic configuration where additional energy storage cells can be switched into or out of the series connection based on operational requirements. The control circuit dynamically adjusts the number of active cells depending on the voltage level, power consumption demands, and charging state, optimizing the balance between power consumption reduction and system complexity.
