Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a single voltage converter is used to supply electric power to the battery, then the system configuration remains simple, but sufficient electric power cannot be supplied to the battery
Solution Approach 1:
The patent merges the functions of multiple voltage converters into a coordinated system where multiple converters work together to supply both the battery and electric loads. This allows sufficient power to be delivered to the battery while sharing the load among multiple converters, avoiding the need for an overly complex single-converter design.
Solution Approach 2:
The voltage converters are designed to serve multiple functions: they can supply power to the battery, power electric loads, and operate in various configurations (single or multiple converters). This multi-functionality allows the system to adapt to different power requirements without requiring completely different system architectures.
2Quantity of substance
If multiple voltage converters are used to supply sufficient electric power to the battery, then the electric power supply amount increases, but the system configuration becomes complicated
Solution Approach 1:
The patent combines multiple voltage converters into a unified control system where they operate cooperatively. The control unit coordinates the multiple converters to work together, managing their activation and power distribution to achieve sufficient battery charging while maintaining manageable system complexity through integrated control.
Solution Approach 2:
The system dynamically adjusts which voltage converters are activated based on real-time power requirements. The control unit can selectively activate one or more voltage converters depending on the current demand from the battery and electric loads, allowing the system to scale its complexity only when necessary.
3Quantity of substance
If the voltage converter outputs more electric power than needed for the battery, then surplus electric power is available, but it requires effective distribution to electric loads
Solution Approach 1:
The control unit continuously monitors the power output from voltage converters and the power consumption of electric loads, adjusting the converter operation in real-time. This feedback mechanism ensures that surplus power from voltage converters is automatically directed to appropriate electric loads, maintaining power balance without complex manual intervention.
Solution Approach 2:
The system automatically manages its own power distribution by having the control unit monitor and adjust voltage converter output based on real-time demands from both battery and electric loads. This self-regulating mechanism ensures surplus power is efficiently utilized without requiring external control or complex distribution infrastructure.
