Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If air is supplied directly to the battery cell module without purification, then the device complexity is reduced, but impurities such as water and carbon dioxide interfere with metal peroxide generation, reducing battery capacity and lifespan
Solution Approach 1:
The air purification module is divided into multiple independent air purifiers, each targeting specific impurities (water, carbon dioxide, nitrogen). This segmentation allows the system to address multiple contamination sources separately, improving purification effectiveness while maintaining manageable device complexity through modular architecture.
Solution Approach 2:
Air is purified before being supplied to the battery cell module, removing impurities in advance to prevent side reactions. The concentration detector continuously monitors air quality, and the controller adjusts air purifier operations proactively to maintain optimal conditions, preventing capacity degradation before it occurs.
2Reliability
If multiple air purifiers are added to filter different impurities, then battery capacity and lifespan are improved, but the device complexity increases
Solution Approach 1:
The controller integrates multiple functions: detecting impurity concentrations, controlling multiple air purifiers, and adjusting oxygen enrichment levels. This centralized control system manages the complex purification process through a single coordination unit, reducing operational complexity despite having multiple air purifiers working simultaneously.
Solution Approach 2:
The concentration detector provides continuous feedback on air quality, enabling the controller to dynamically adjust air purifier operations. This closed-loop control system optimizes purification effectiveness by responding to real-time impurity levels, ensuring battery capacity is maintained while avoiding unnecessary operation of air purifiers when air quality is already acceptable.
3Use of energy by moving object
If oxygen concentration is enriched in the supplied air, then battery energy density is improved, but the device complexity and energy consumption increase
Solution Approach 1:
The air purification module dynamically adjusts oxygen enrichment levels based on real-time impurity concentrations detected by the concentration detector. When impurity levels are low, oxygen enrichment is reduced or suspended, decreasing energy consumption. When impurities are high, enrichment is increased to maintain battery performance, creating a dynamic balance between energy density and energy consumption.
