Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional vertical lead storage battery structure is used, then manufacturing process is established, but electrolyte stratification occurs and plate reaction becomes uneven
Solution Approach 1:
The patent inverts the traditional vertical battery structure to a horizontal configuration. The plate groups are arranged horizontally within the battery container, with partitions separating adjacent plate groups. This inversion eliminates electrolyte stratification and ensures uniform plate reaction by allowing electrolyte to distribute evenly across all plates throughout the charge-discharge cycles.
2Reliability
If traditional welding processes are used for lug and bridge connection, then electrical connection is achieved, but manufacturing complexity and pollution increase
Solution Approach 1:
The patent merges the lug and bridge connection functions into a single integrated horizontal structure. The positive and negative plates of adjacent plate groups are directly connected through horizontal bridges without requiring separate lug welding or bridge assembly. This eliminates multiple welding processes and reduces manufacturing complexity while maintaining reliable electrical connection.
Solution Approach 2:
The patent extracts and eliminates the traditional lug welding and bridge lead parts from the battery structure. By adopting horizontal plate groups with direct plate-to-plate connections, the complex welding processes and associated lead parts are completely removed, simplifying manufacturing and reducing pollution.
3Ease of manufacture
If horizontal plate groups are used with gaps between partitions, then assembly is simplified, but sealing performance deteriorates
Solution Approach 1:
The patent applies preliminary sealing action by installing sealing components in the gaps between partitions before final assembly. The sealing components are pre-positioned to ensure proper sealing, allowing the battery to be assembled with simplified procedures while maintaining excellent sealing performance. This preliminary sealing action prevents electrolyte leakage and ensures reliable operation.
