Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional battery assembly structure is used, then the structure is simple, but humidity accumulates inside causing electrical safety issues
Solution Approach 1:
The battery assembly is divided into functional modules: battery packs, pipe modules, and drain case modules. This segmentation allows the humidity removal function to be added as a separate module rather than redesigning the entire structure, thus improving electrical safety while controlling overall complexity.
Solution Approach 2:
The pipe module acts as an intermediary component between the battery packs and the drain case. It provides a dedicated pathway for humidity to travel from the battery compartment to the drainage system, enabling electrical safety improvement without requiring direct modification of the battery packs or case structure.
2Reliability
If additional humidity removal devices are added, then humidity can be removed effectively, but the structure becomes more complex and size increases
Solution Approach 1:
The humidity removal function is merged with the existing structural components. The pipe module utilizes the natural gravitational flow path, and the drain case integrates with the bottom of the battery assembly, combining multiple functions (drainage, humidity collection, and structural support) into unified components rather than adding separate dedicated systems.
Solution Approach 2:
The system uses passive gravity-driven drainage rather than active pumping mechanisms. Condensed humidity naturally flows down the pipe module into the drain case and exits through the drainage hole without requiring additional power devices or complex control systems, thus removing humidity effectively while minimizing size and complexity additions.
3Device complexity
If passive gravity-driven drainage is used, then the structure is simplified and no power devices are needed, but drainage efficiency may be reduced
Solution Approach 1:
The drainage system utilizes the vertical dimension by positioning the drain case at the bottom of the assembly and the pipe module extending downward from the battery packs. This vertical arrangement maximizes gravitational effect, allowing efficient passive drainage without requiring horizontal transport mechanisms or additional power devices.
Solution Approach 2:
The pipe module is strategically positioned to contact or be near the battery packs, creating a localized condensation zone where humidity is most prevalent. The drainage hole is positioned at the lowest point of the case to ensure complete drainage. This localized optimization ensures efficient humidity removal at critical points without requiring a complex system throughout the entire assembly.
