Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If charging power is increased to improve charging speed, then charging speed is improved, but temperature increases causing safety issues and reduced service life
Solution Approach 1:
The patent applies preliminary action by performing temperature prediction before actual charging occurs. The prediction model forecasts future temperature trends based on charging power, ambient temperature, and historical data, allowing the system to proactively adjust charging parameters to prevent overheating while maintaining high charging speeds.
Solution Approach 2:
The patent implements feedback control by continuously monitoring actual temperature during charging and comparing it with predicted temperature. The system dynamically adjusts charging power based on the difference between actual and predicted temperatures, creating a closed-loop control mechanism that maintains optimal charging speed while preventing temperature-related safety issues.
2Reliability
If temperature is controlled within a set range to prevent overheating, then safety is improved, but charging speed may be reduced
Solution Approach 1:
The patent applies dynamics by making the charging power adjustable and dynamic rather than fixed. The system continuously modifies charging power levels based on real-time temperature conditions and predicted temperature trends, allowing the charging speed to adapt dynamically to safety requirements while maximizing charging efficiency within safe operating parameters.
Solution Approach 2:
The patent implements parameter changes by adjusting charging power as a variable parameter based on temperature conditions. The system changes operating parameters (charging power levels) in response to temperature measurements and predictions, enabling the balance between safety and charging speed to be optimized through continuous parameter adjustment rather than fixed settings.
3Temperature
If temperature adjustment components are added to control temperature, then temperature control capability is improved, but device complexity increases
Solution Approach 1:
The patent applies mechanics substitution by replacing physical temperature adjustment mechanisms (such as heating elements or cooling systems) with a control-based approach. Instead of adding mechanical components to actively adjust temperature, the system uses intelligent control algorithms that adjust charging power parameters to achieve temperature management, thereby avoiding increased device complexity while maintaining temperature control capability.
