Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If battery cells are isolated in sealed chambers to prevent thermal propagation, then thermal safety is improved, but electrical connectivity and sealing reliability deteriorate
Solution Approach 1:
The connector is divided into multiple independent sealing regions, each with its own gasket and sealing mechanism. The plate structure segments the sealed chamber into distinct compartments, allowing electrical connectivity while maintaining isolation between battery cells to prevent thermal propagation.
Solution Approach 2:
Gaskets serve as intermediary sealing elements between the plate and the sealed chamber,以及between the connector components. These gaskets provide the necessary sealing function while allowing the electrical connector to pass through, resolving the conflict between sealing integrity and electrical connectivity.
2Object-affected harmful factors
If IP68 sealing is implemented to isolate battery cells, then thermal runaway isolation is improved, but device complexity increases
Solution Approach 1:
The sealing function and electrical connectivity function are merged into a single integrated connector assembly. The plate structure combines the sealing surface, connector housing, and electrical contact elements into one component, achieving IP68 sealing without proportionally increasing complexity.
Solution Approach 2:
The connector assembly performs multiple functions simultaneously: it provides IP68 sealing, enables electrical connectivity, and maintains structural integrity. The gasket serves both as a sealing element and as a mechanical feature for assembly, reducing the need for separate components.
3Productivity
If high-density current transfer is supported, then power transmission efficiency is improved, but heat generation increases
Solution Approach 1:
The sealed chamber acts as a thermal intermediary, isolating the heat generated by high-density current transfer from the surrounding environment. This allows efficient power transmission while containing thermal effects within the sealed compartment.
Solution Approach 2:
The sealed chamber creates a controlled environment that isolates thermal effects. By sealing the chamber with IP68 rating, the system prevents external factors from interfering with the thermal management of high-density current pathways.
