A connecting terminal with a snap-fit structure is designed to facilitate easy assembly and disassembly of the sampling module, allowing for efficient connection to both the sampling circuit and the busbar, and enabling straightforward replacement of faulty components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional assembly methods are used to install sampling circuits, then the sampling circuit can be connected to the busbar, but the assembly process is cumbersome and error-prone, reducing assembly efficiency
Solution Approach 1:
The patent introduces a connecting terminal as an intermediary component between the sampling circuit and the busbar. This connecting terminal integrates both connection functions into a single component, simplifying the assembly process and eliminating the need for separate connection steps, thereby improving assembly efficiency while reducing operational complexity
Solution Approach 2:
The patent merges the connection of the sampling circuit and the busbar into a single integrated connecting terminal. By combining two separate connection functions into one component, the assembly process becomes simpler and more efficient, directly addressing the contradiction between productivity and ease of operation
2Reliability
If the sampling circuit is permanently integrated into the battery module, then the connection is stable, but replacing faulty sampling circuits requires discarding the entire battery module, increasing waste
Solution Approach 1:
The patent segments the sampling circuit connection from the battery module by introducing a removable connecting terminal. This allows the sampling circuit to be independently replaced without affecting the battery module, maintaining connection stability through the terminal's design while enabling selective replacement of only the faulty sampling circuit, thus reducing waste
Solution Approach 2:
The patent enables the recovery and reuse of the battery module by allowing only the sampling circuit to be replaced. The connecting terminal facilitates this by providing a standardized interface that preserves the battery module for continued use, directly reducing material waste while maintaining reliable connections
3Ease of repair
If the sampling circuit can be easily removed from the busbar, then replacement is simple, but the connection stability and reliability may be compromised
Solution Approach 1:
The connecting terminal employs a dynamic connection mechanism that provides both stable connection during operation and easy removal when needed. The terminal's design allows it to maintain firm electrical contact during battery operation while enabling simple extraction for replacement, thus achieving both connection reliability and ease of repair
Solution Approach 2:
The connecting terminal serves as a mediator that balances connection stability and replaceability. Its intermediate position between the sampling circuit and busbar allows it to provide stable electrical connection during operation while enabling easy removal and replacement, resolving the contradiction between reliability and ease of repair
