Battery Connector Transition Part Avoids Tab Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional battery connectors interfere with the tabs of battery winding electrode cores, causing wrinkles and potential damage, especially during shocks, which reduces the battery's working life.
Innovation Solution
A battery connector design with a transition part that matches the shape of the gap between adjacent tabs, avoiding interference and enhancing structural integrity by being integrally formed with a terminal connecting part and an electrode core connecting part, ensuring a simple structure, high material utilization, and low cost.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional connector is used for battery, then the connector can connect the electrode terminal with the tab, but the connector interferes with the tab causing wrinkles and potential damage
Solution Approach 1:
The connector is divided into three distinct parts: terminal connecting part, electrode core connecting part, and transition part. This segmentation allows each part to perform its specific function while avoiding interference with adjacent components, particularly the tab structure.
Solution Approach 2:
The transition part acts as an intermediary element between the terminal connecting part and the electrode core connecting part. It is specifically designed to fit within the gap between adjacent tabs, serving as a mediator that prevents direct contact and potential damage between the connector and tab structures.
2Ease of manufacture
If the connector structure is simplified to reduce cost, then manufacturing becomes easier, but the connector may interfere with adjacent tabs
Solution Approach 1:
The connector integrates multiple functions into a single component: electrical connection at the terminal, electrical connection at the electrode core, and mechanical spacing between tabs. This merging eliminates the need for separate components while maintaining protection against tab interference.
Solution Approach 2:
The transition part has a specific local geometry designed to match the gap between tabs. This localized structural feature provides the necessary spacing and protection only where needed, without adding complexity to the entire connector structure.
3Reliability
If the connector is designed to avoid interference with tabs, then battery reliability improves, but the connector structure becomes more complex
Solution Approach 1:
The transition part is designed with flexibility to adapt to the specific gap dimensions between tabs. This dynamic characteristic allows the connector to accommodate variations in tab positioning without requiring precise pre-matching, simplifying the overall design while maintaining reliability.
