Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If voltage conversion is performed through charger and boost converter, then voltage compatibility is achieved, but power efficiency deteriorates due to power loss
Solution Approach 1:
The patent extracts the voltage conversion function from the mandatory power path by introducing a bypass path. When input voltage is compatible with the battery, power flows directly through the bypass path without undergoing double conversion, thereby eliminating unnecessary power loss while maintaining voltage compatibility when needed.
Solution Approach 2:
The system dynamically switches between two power paths: the conventional conversion path (when voltage conversion is needed) and the bypass path (when input voltage is compatible). This dynamic adjustment optimizes power efficiency based on real-time voltage conditions while maintaining adaptability to different charging scenarios.
2Adaptability or versatility
If double voltage conversion is performed, then voltage compatibility is ensured, but temperature increases due to power loss
Solution Approach 1:
The patent removes the heat-generating voltage conversion steps from the power path by introducing a bypass path. When input voltage matches battery requirements, power flows directly without conversion, eliminating the source of heat generation while preserving voltage compatibility capability when conversion is actually needed.
3Reliability
If conventional battery power supply system is used, then battery charging is achieved, but battery life is reduced due to repeated conversion
Solution Approach 1:
The patent extracts the harmful repeated conversion process from the charging path. By providing a bypass path that allows direct power flow when voltage is compatible, the system eliminates the stress of double conversion on the battery, thereby extending battery life while maintaining reliable charging functionality.
