Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If multiple battery cells are stacked and connected with busbars to optimize internal space, then the space utilization is improved, but the temperature rise during charging and discharging worsens
Solution Approach 1:
The patent divides the battery pack into multiple independent battery cells arranged in a stacked configuration. Each battery cell is separated by insulating components, creating modular units that can be independently managed thermally while maximizing space utilization within the battery pack.
Solution Approach 2:
The patent introduces thermal management components as intermediary elements between battery cells. These components include cooling plates with fluid channels that act as heat transfer mediators, conducting heat away from the battery cells during charging and discharging operations to prevent excessive temperature rise.
2Temperature
If thermal management components are added to control battery temperature, then the temperature regulation ability is improved, but the heat exchange with external environment worsens
Solution Approach 1:
The patent applies thermal insulation members selectively at specific locations where heat loss occurs, such as between battery cells and at the ends of the battery pack. This localized insulation approach reduces unnecessary heat exchange with the external environment while maintaining effective thermal management through the cooling plates that are in direct contact with the battery cells.
3Loss of energy
If thermal insulation measures are implemented to reduce heat loss, then the energy loss is reduced, but the temperature management complexity increases
Solution Approach 1:
The patent combines multiple functions into integrated components. The thermal management components serve dual purposes: they act as cooling plates for active heat removal through fluid channels, and simultaneously provide structural support and mounting surfaces for electrical connections. Thermal insulation members are positioned to provide both insulation and electrical isolation, reducing the need for separate components.
