Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the fire control system operates independently without integrating state information from energy storage units, then the system structure remains simple, but the temperature control accuracy and thermal runaway prevention capability are insufficient
Solution Approach 1:
The patent merges the fire control system with the energy storage management system by integrating temperature monitoring and control functions. The fire control system no longer operates independently but instead receives state information from energy storage units and coordinates with the management system to determine operating modes for heat management and fire-fighting units, achieving unified temperature control and safety management.
Solution Approach 2:
The energy storage management system is enhanced to perform multiple functions: it not only manages the energy storage units but also integrates fire control capabilities. The system can determine operating modes for both heat management and fire-fighting units based on state information, making the management system a multi-functional platform that handles both operational control and safety management.
2Reliability
If the heat management unit operates alone without fire-fighting unit coordination, then the control system remains simple, but the system cannot effectively prevent thermal runaway when temperature limits are exceeded
Solution Approach 1:
The system performs preliminary action by proactively monitoring state information and determining operating modes before thermal runaway occurs. The fire-fighting unit is prepared and can be activated based on predicted temperature trends and state information analysis, preventing thermal runaway rather than merely responding to it after occurrence.
Solution Approach 2:
The control system dynamically adjusts operating modes of both heat management and fire-fighting units based on real-time state information. The system transitions between different operating modes (such as normal operation, warning, and emergency modes) according to temperature conditions and state parameters, enabling flexible and adaptive thermal runaway prevention.
3Reliability
If state information is not integrated into fire control decisions, then the response time remains fast, but the temperature control effectiveness and system safety are compromised
Solution Approach 1:
The system implements feedback by continuously acquiring state information from energy storage units and using this information to determine appropriate operating modes for heat management and fire-fighting units. The state information serves as feedback that closes the control loop, enabling the system to adjust its response based on actual conditions and improve overall safety.
