Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a large-capacity battery charging/discharging system is constructed to meet increasing demand, then testing capacity is improved, but facility construction cost and space requirements increase
Solution Approach 1:
The patent combines the battery charging/discharging system with an air conditioning system into a single integrated facility. The air conditioning system's cooling capability is utilized to manage heat from battery testing, while the system itself provides cooling for the facility. This merging allows the same physical space to serve dual purposes: battery testing and temperature control, thereby increasing testing capacity without proportionally increasing facility space requirements.
2Temperature
If separate air conditioning facilities are constructed to cool the battery charging/discharging system, then temperature control is improved, but construction cost and maintenance cost increase
Solution Approach 1:
The air conditioning system is designed to perform multiple functions: it cools the facility environment and simultaneously removes heat generated during battery charging/discharging operations. The cooling capacity is sized to handle both the facility's ambient cooling needs and the thermal load from battery testing. This multi-functionality eliminates the need for separate air conditioning facilities, reducing construction and maintenance costs while maintaining effective temperature control.
3Power
If the charger/discharger operates in high-power mode, then charging/discharging capacity is improved, but heat generation increases requiring additional cooling
Solution Approach 1:
The patent converts the harmful heat generated during high-power charging/discharging operations into a useful resource. The air conditioning system's cooling capacity is designed to absorb and remove this heat, and in doing so, it provides cooling for the entire facility. The heat that would otherwise be a harmful byproduct requiring separate disposal becomes the primary cooling load for the air conditioning system, which simultaneously serves the facility's temperature control needs.
