Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If different sizes of circuit boards of voltage stabilizers are disposed in power supply systems to meet different power requirements, then voltage stabilization performance is improved, but space utilization decreases
Solution Approach 1:
The patent implements a dynamic circuit board sizing mechanism where the voltage stabilizer circuit board automatically adjusts its operating parameters based on real-time power requirements. The control unit monitors the actual power demand and dynamically configures the stabilizer circuit to provide appropriate voltage stabilization, eliminating the need for multiple fixed-size circuit boards and optimizing space utilization while maintaining stabilization performance.
Solution Approach 2:
The patent designs a universal voltage stabilizer circuit board that can handle multiple power requirements through configurable operating modes. The stabilizer circuit is capable of providing different levels of voltage stabilization for various power loads, making a single circuit board design suitable for all power supply system configurations, thereby improving space utilization without compromising voltage stabilization performance.
2Power
If an additional power supply system cabinet capable of supplying higher voltage is purchased to meet external device voltage requirements, then voltage supply capability is improved, but system cost and complexity increase
Solution Approach 1:
The patent employs parameter change technology where the voltage stabilizer circuit dynamically adjusts its output voltage parameters based on the connected load requirements. The control unit monitors voltage demands and modifies the stabilizer circuit's operating parameters to provide the necessary voltage levels, eliminating the need for additional high-voltage power supply cabinets and reducing system complexity while maintaining adequate voltage supply capability.
3Adaptability or versatility
If the power supply system is designed with a maximum voltage of 52V to accommodate future needs, then adaptability is improved, but battery charging capability deteriorates due to insufficient voltage for full charging
Solution Approach 1:
The patent implements a dynamic voltage adjustment mechanism in the stabilizer circuit that can temporarily increase output voltage beyond the standard 52V maximum when battery charging is detected. The control unit identifies charging scenarios and dynamically raises the voltage parameter to the required level for complete battery charging, then returns to normal operating voltage, thus maintaining both adaptability and reliable battery charging capability.
