Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the auxiliary energy storage element is charged only from the power unit, then the charging system is simple, but the charging cannot proceed when the power unit is not operational
Solution Approach 1:
The charging supply circuit is designed to accept power from multiple sources (power unit and external energy source) and perform the same charging function regardless of which source is available. This multi-functionality ensures the auxiliary energy storage element can be charged in various operational scenarios, resolving the contradiction between charging availability and system complexity.
Solution Approach 2:
The charging supply circuit dynamically switches between different power sources based on availability. The circuit can adaptively select whether to charge from the power unit or external energy source, providing flexible charging capability that maintains reliability while managing complexity through intelligent control.
2Productivity
If the charging supply circuit uses a single power source, then the circuit design is simple, but the charging speed is limited by the single source's power output
Solution Approach 1:
The charging supply circuit merges power from multiple sources (power unit and external energy source) to provide combined charging power. This combination allows the auxiliary energy storage element to charge faster by utilizing the aggregate power capacity of both sources, resolving the contradiction between charging speed and circuit complexity.
Solution Approach 2:
The charging supply circuit is designed to handle multiple power sources simultaneously, providing universal charging capability that can operate in single-source or multi-source modes. This multi-functionality enables flexible power combination for accelerated charging while maintaining manageable circuit complexity through standardized design.
3Reliability
If the auxiliary energy storage element is not rechargeable, then the auxiliary unit is simpler, but the auxiliary battery must be periodically replaced
Solution Approach 1:
The auxiliary energy storage element is designed to be rechargeable from the power unit during normal operation. This self-service capability allows the auxiliary battery to replenish its own charge using the system's power output, eliminating the need for external charging or periodic replacement and thereby improving availability while managing complexity through integrated charging functionality.
