Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If real-time communication is maintained to detect impacts and congestion during battery logistics movement, then detection reliability is improved, but power consumption increases
Solution Approach 1:
The communication period is made dynamic rather than fixed. The controller adjusts the communication period based on the available limit of the power supply unit, allowing the system to adapt its communication frequency to current power conditions while maintaining necessary detection reliability.
Solution Approach 2:
The system changes the communication parameter (communication period) based on environmental conditions and power availability. By calculating the available limit based on temperature and humidity differences, the system optimizes the balance between detection reliability and power consumption.
2Use of energy by moving object
If communication period is reduced to save power, then power consumption decreases, but detection responsiveness deteriorates
Solution Approach 1:
The system uses feedback from environment sensors to continuously monitor temperature and humidity conditions. This feedback loop allows the controller to calculate the available power limit and adjust the communication period dynamically, ensuring that detection responsiveness is maintained within acceptable ranges while optimizing power consumption.
Solution Approach 2:
The communication period is made dynamic rather than fixed. The controller adjusts the communication period based on the available limit of the power supply unit, allowing the system to adapt its communication frequency to current power conditions while maintaining necessary detection reliability.
3Reliability
If environmental monitoring is added to calculate available power limit, then power management accuracy is improved, but device complexity increases
Solution Approach 1:
The environment sensor serves multiple functions: it monitors both the operational environment (temperature and humidity) and provides data for calculating the available power limit. This multi-functionality reduces the need for separate power management sensors, thereby limiting the increase in device complexity while improving power management accuracy.
Solution Approach 2:
The system merges environmental monitoring with power management functions. By using the same environment sensor data for both operational monitoring and power limit calculation, the system reduces overall component complexity while achieving accurate power management.
