Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a battery is charged through direct connection to mains supply, then charging reliability is improved, but charging availability deteriorates when power source is unavailable
Solution Approach 1:
The battery system is designed to perform multiple charging functions: it can charge through direct mains supply connection (via the interface unit) and also charge wirelessly through electromagnetic wave capture (via the wireless charging unit). This multi-functionality allows the battery to adapt to different charging scenarios and power source availability, resolving the contradiction between charging reliability and charging availability.
2Adaptability or versatility
If wireless electromagnetic wave charging is implemented, then charging availability is improved, but energy conversion efficiency deteriorates
Solution Approach 1:
The control unit dynamically manages the charging process by detecting battery parameters and controlling the wireless charging unit accordingly. The system can switch between charging modes (mains supply vs. electromagnetic wave) based on real-time conditions, optimizing energy conversion efficiency while maintaining charging availability. The dynamic control ensures that wireless charging is utilized appropriately without excessive energy loss.
3Measurement precision
If control unit manages charging based on battery parameters, then charging precision is improved, but device complexity deteriorates
Solution Approach 1:
The control unit implements a feedback mechanism by detecting battery parameters (such as charge level, voltage, current) and using this information to control the charging process. The control unit adjusts charging parameters based on detected battery states, ensuring precise and safe charging. This feedback-based control achieves high charging precision while managing device complexity through intelligent control algorithms.
