Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a pulse current with pulse width less than 1 μs is used to remove lead sulfate film, then the sulfate removal effect is improved, but the device complexity and manufacturing cost increase due to requiring separate oscillator, amplifier, waveform shaping circuit and negative pulse generator
Solution Approach 1:
The patent combines multiple separate circuits (oscillator, amplifier, waveform shaping circuit, negative pulse generator) into a single integrated control circuit that generates the required pulse current waveform. This merging reduces device complexity and manufacturing cost while maintaining the pulse width less than 1 μs necessary for effective sulfate removal through conduction skin effect.
Solution Approach 2:
The control circuit is designed to perform multiple functions: generating the oscillating signal, amplifying it to required current levels, shaping the waveform to achieve pulse width less than 1 μs, and providing negative pulse generation. This multi-functionality eliminates the need for separate dedicated circuits for each function, simplifying the overall device structure.
2Manufacturing precision
If a high-voltage pulse of 1200V to 1400V is applied to electrodes for 9 hours, then the oxide film removal effect is improved, but the device complexity increases due to requiring pulse generator and rectifier
Solution Approach 1:
The patent integrates the pulse generation and rectification functions into a unified control circuit that directly generates the high-voltage pulse current without requiring separate pulse generator and rectifier components. The circuit applies pulses of 1200V to 1400V for 9 hours to remove oxide films from lead sulfate deposits while maintaining simplified device architecture.
Solution Approach 2:
The control circuit is designed to automatically generate and regulate the high-voltage pulses required for oxide film removal, eliminating the need for external pulse generators or rectifiers. The system self-regulates the voltage and timing parameters to achieve effective oxide film removal while maintaining operational simplicity.
3Manufacturing precision
If conventional recycling apparatus with multiple separate circuits is used, then the sulfate removal capability is achieved, but the power consumption increases and durability decreases
Solution Approach 1:
By consolidating multiple separate circuits into a single integrated control circuit, the patent reduces redundant power consumption associated with multiple independent power supplies and control systems. The unified circuit architecture maintains effective sulfate removal capability while improving energy efficiency and reducing overall power consumption of the recycling apparatus.
