Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If battery cells are laid in parallel on one layer, then the power supply can supply maximum voltage, but the volume occupied by the power supply is large
Solution Approach 1:
The patent transitions from a single-layer parallel arrangement to a multi-layer stacked configuration, adding the vertical dimension to the battery cell layout. This allows multiple layers of battery cells to be stacked vertically within the same footprint, increasing voltage capacity while maintaining a compact overall volume.
Solution Approach 2:
The patent implements a nested structure where battery cells are arranged in concentric or stacked patterns, with inner cells surrounded by outer cells. This nesting approach maximizes the use of available space, allowing more battery cells to be packed into a smaller volume while maintaining electrical connectivity for high voltage output.
2Power
If battery cells are laid in parallel on one layer, then the power supply can supply maximum voltage, but it requires disassembly of the cleaner to separate the power supply
Solution Approach 1:
The patent divides the battery system into modular segments, with each battery cell or group of cells forming an independent module. These modular segments are connected through flexible bus bars or connectors, allowing the power supply to be separated into individual battery cell modules that can be easily removed or serviced without disassembling the entire cleaner.
Solution Approach 2:
The patent employs dynamic or flexible connection methods between battery cells, such as spring-loaded connectors or detachable bus bars, that allow for easy assembly and disassembly. This enables the power supply to be separated and reconfigured as needed while maintaining stable electrical connections during operation.
3Power
If battery cells are laid in parallel on one layer, then the power supply can supply maximum voltage, but the cooling performance is limited
Solution Approach 1:
The patent arranges battery cells in a multi-layer stacked configuration with vertical spacing between layers, creating additional thermal pathways in the vertical dimension. This three-dimensional arrangement improves heat dissipation by allowing heat to escape from multiple surfaces and facilitating airflow or thermal conduction through the stacked structure.
Solution Approach 2:
The patent implements localized cooling solutions at critical heat-generating points, such as placing thermal pads, heat sinks, or cooling channels directly adjacent to battery cell terminals or high-current connection points. This targeted approach ensures that hot spots are effectively managed while maintaining overall thermal balance in the power supply assembly.
