Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the energy storage device continuously discharges to meet peak power demands, then the power delivery capability is improved, but the temperature of the energy storage device increases leading to safety issues and reduced reliability
Solution Approach 1:
The patent implements dynamic temperature-based control of the energy storage device. The control subsystem continuously monitors temperature and dynamically adjusts the discharge enablement state between enabled and disabled based on whether temperature thresholds are exceeded. This dynamic adjustment allows the system to maximize power delivery when safe and prevent overheating when necessary, resolving the contradiction between power delivery capability and temperature control.
2Device complexity
If the energy storage device operates without temperature-based control, then the system complexity is reduced, but the reliability and safety of the system deteriorates due to uncontrolled temperature rise
Solution Approach 1:
The control subsystem automatically monitors temperature and makes decisions about discharge enablement without requiring external intervention or complex control algorithms. The system uses simple threshold-based logic where the temperature sensor directly controls the discharge enablement state, allowing the energy storage device to self-regulate its operation based on its own thermal state, thereby maintaining high reliability with minimal added complexity.
3Temperature
If the energy storage device disables discharging to prevent overheating, then the temperature control is improved, but the power delivery capability to meet peak demands is reduced
Solution Approach 1:
The control subsystem periodically monitors the temperature of the energy storage device and alternates the discharge enablement state between enabled and disabled based on temperature threshold crossings. This periodic monitoring and state switching allows the system to achieve both temperature control and power delivery by enabling discharge during safe temperature periods and disabling only when necessary, rather than maintaining a fixed disabled state.
