Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a switch and resistor are used for discharging the backup power supply, then the discharging process can be initiated, but the discharging current varies and causes deviation in capacity calculation
Solution Approach 1:
The patent changes the discharging current parameter from variable to constant by introducing a constant current source circuit. This circuit maintains a fixed discharging current regardless of the backup power supply's voltage changes, ensuring accurate capacity calculation while keeping the operation simple through automated control.
Solution Approach 2:
The patent replaces the simple mechanical switch-resistor discharging system with an electronically controlled constant current source system. This substitution uses electronic components (MOSFETs, operational amplifiers, reference voltage sources) to precisely control the discharging current, eliminating the current variation problem while maintaining ease of operation through electronic control signals.
2Adaptability or versatility
If different types of energy storage modules are used, then versatility is improved, but determining appropriate discharging currents becomes complex
Solution Approach 1:
The patent creates a universal discharging circuit that can work with different types of energy storage modules (batteries, supercapacitors, etc.). The constant current source circuit and control module are designed to accommodate various module types by simply changing the control signal parameters, eliminating the need for different hardware configurations for different module types.
Solution Approach 2:
The patent introduces dynamic adaptability through the control module, which can adjust the discharging current based on the specific type of energy storage module being used. The system dynamically selects appropriate current values from preset ranges (e.g., 0.2C-0.5C for batteries, 1C-3C for supercapacitors) based on module identification, providing both universality and optimized performance for each type.
