A charging system for electric aircraft that includes a charger port, a sensor to detect charging data, and a controller to compare this data to pre-set thresholds, detecting charging failures and recording them in a database, while also initiating mitigating responses like stopping electricity flow and alerting users.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If charging systems operate without monitoring and control mechanisms, then charging speed and convenience are improved, but safety and reliability deteriorate due to short circuits, disconnections, and battery overheating
Solution Approach 1:
The patent implements a feedback mechanism where sensors continuously monitor charging parameters (current, voltage, temperature) and transmit data to a controller. The controller compares actual values with expected ranges and automatically adjusts or terminates charging when anomalies are detected, creating a closed-loop control system that maintains safety without compromising convenience
Solution Approach 2:
The patent introduces an intermediary control system between the power source and the battery. This intermediary includes controllers and sensors that mediate the charging process by monitoring parameters and controlling power flow, preventing direct harmful interactions between the charger and battery while maintaining efficient charging
2Reliability
If charging systems implement comprehensive monitoring and control mechanisms, then safety and reliability are improved, but device complexity increases due to additional sensors and controllers
Solution Approach 1:
The patent designs controllers that perform multiple functions: monitoring various charging parameters, comparing data against thresholds, controlling power flow, and logging events. This multi-functionality reduces the need for separate dedicated components for each task, thereby limiting the increase in system complexity while maintaining comprehensive safety monitoring
3Loss of information
If charging failures are detected and recorded in a database, then loss of information is reduced for analysis, but loss of time increases due to data recording and processing
Solution Approach 1:
The patent implements preliminary action by continuously monitoring and pre-processing charging data during the charging process itself. When anomalies are detected, the system immediately logs the relevant information with timestamps and terminates the charging session, rather than requiring post-charging analysis. This approach retains critical information while minimizing additional processing time by acting in real-time
