Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If battery units are arranged close to one another for saving space, then space utilization is improved, but heat dissipation deteriorates
Solution Approach 1:
The patent combines the electrical connection function and thermal conduction function into a single integrated structure. The electrically conductive sheet serves dual purposes: connecting battery terminals electrically and conducting heat away from battery units. This merging eliminates the need for separate cooling apparatus while maintaining both electrical connectivity and thermal management in the compact battery arrangement.
2Temperature
If liquid/air cooling heat dissipation apparatus is used, then heat dissipation is improved, but device complexity and cost increase
Solution Approach 1:
The patent implements self-service thermal management where the battery system's own electrical connection structure performs the cooling function. The electrically conductive sheet, which is already present for electrical connectivity, simultaneously acts as a heat conduction path. This eliminates the need for additional active cooling systems, reducing device complexity and aligning with energy conservation principles.
3Device complexity
If electrically conductive sheet is used for both electrical connection and thermal conduction, then device complexity is reduced, but electrical insulation may be compromised
Solution Approach 1:
The patent segments the thermal management function across multiple battery units rather than requiring a single complex insulation solution. The electrically conductive sheet makes contact with only specific portions of each battery unit (the terminals), while the broader surfaces remain thermally coupled through the sheet. This segmentation allows thermal conduction through the electrically conductive sheet without compromising electrical insulation, as the contact areas are localized and controlled.
