Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electrode assemblies are immersed in electrolyte to ensure normal operation, then the energy-storage device can function properly, but the electrolyte level decreases during charging and discharging, causing incomplete immersion of electrode assemblies
Solution Approach 1:
The patent introduces a movable displacement plate that can dynamically adjust its position to compensate for electrolyte level changes. The displacement plate moves upward as electrolyte is consumed during charging and discharging, maintaining continuous contact with the electrode assembly and ensuring complete immersion throughout the operational cycle.
Solution Approach 2:
The displacement plate is designed to move automatically based on electrolyte level changes without requiring external control systems. As the electrolyte level drops, the displacement plate rises accordingly, and when electrolyte is replenished, the plate descends, creating a self-regulating mechanism that maintains proper immersion.
2Productivity
If electrolyte level decreases during charging and discharging, then the energy-storage device operates, but part of the electrode assembly cannot be immersed in electrolyte, affecting performance
Solution Approach 1:
The movable displacement plate dynamically adjusts its height to match electrolyte level changes during charging and discharging operations. This dynamic adjustment ensures that the electrode assembly remains fully immersed in electrolyte throughout the entire operational cycle, preventing performance degradation.
Solution Approach 2:
The displacement plate acts as an intermediary element between the electrode assembly and the housing. It compensates for electrolyte level fluctuations by moving vertically, thereby maintaining the necessary immersion depth of the electrode assembly without requiring additional electrolyte or modifying the electrode structure.
3Duration of action of moving object
If electrolyte level decreases, then charging and discharging can proceed, but the service life of the energy-storage device is shortened
Solution Approach 1:
The movable displacement plate continuously adapts to electrolyte level changes over extended operational periods. By maintaining proper immersion depth throughout numerous charging and discharging cycles, the system prevents electrode damage and electrolyte depletion, thereby extending the overall service life of the energy-storage device.
Solution Approach 2:
The displacement plate provides preventive protection by maintaining electrode immersion before complete electrolyte depletion can occur. This proactive mechanism prevents damage to the electrode assembly and other critical components, cushioning against failures that would otherwise shorten the device's service life.
