Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single power source with DC-DC step-down circuit is used to charge multiple batteries, then charging capability is provided, but hardware cost increases and heat treatment and electromagnetic compatibility challenges arise
Solution Approach 1:
The system divides the charging function into multiple independent power modules, where each power module can independently charge one battery. This segmentation eliminates the need for complex DC-DC step-down circuits in a single centralized power source, reducing hardware cost while maintaining the ability to charge multiple batteries simultaneously.
Solution Approach 2:
Each power module is designed with universal functionality to charge any battery type through standardized interfaces. The microprocessor enables flexible allocation and management of multiple power modules, allowing them to serve different batteries dynamically, thus providing adaptability without requiring specialized circuits for each battery.
2Productivity
If multiple batteries are charged manually with repetitive connections, then charging is possible, but operation complexity and time consumption increase
Solution Approach 1:
The system implements automatic battery identification and power module allocation through microprocessor control. When batteries are connected, the system automatically detects their status and assigns appropriate power modules without requiring manual intervention. The system also automatically manages charging processes and detects when batteries are fully charged, eliminating repetitive manual operations.
Solution Approach 2:
The system performs preliminary detection of battery status and power module availability before charging begins. The microprocessor pre-allocates power modules to batteries based on their charging needs, and the system prepares charging circuits in advance, so that when a battery is connected, charging can start immediately without manual setup or configuration.
3Power
If DC-DC step-down circuits are used for high power supply, then power delivery is achieved, but heat treatment and electromagnetic compatibility costs increase
Solution Approach 1:
Instead of using a single high-power DC-DC step-down circuit that generates heat and electromagnetic interference, the system segments the power delivery function across multiple independent power modules. Each module delivers power at appropriate levels directly to its assigned battery, eliminating the need for high-voltage step-down conversion and associated thermal and electromagnetic management complexities.
