Elastic Charging Probe Structure for Tilted Battery Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Poor contact between charging/discharging probes and electrode terminals of secondary batteries due to tilting, leading to additional contact resistance and hindered charging, discharging, or testing processes.
Innovation Solution
Incorporation of guide rods made of elastic members, such as plate springs, in the charging/discharging probes and jigs to maintain stable contact by allowing flexible movement and prevent horizontality collapse of electrode terminals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If rigid guide rods are used in charging/discharging probes, then structural stability is improved, but contact stability deteriorates when electrode terminals are tilted
Solution Approach 1:
The guide rod is designed with a flexible section that can dynamically adjust its position and angle in response to tilting of the electrode terminal. This flexible section allows the probe to adapt to positional changes while maintaining stable electrical contact, resolving the contradiction between structural stability and contact stability.
Solution Approach 2:
The guide rod incorporates materials or structural features that change their mechanical parameters (such as flexibility or elasticity) to accommodate tilting angles. By changing the physical state or properties of the guide rod, it can maintain contact stability even when the electrode terminal position varies.
2Device complexity
If fixed-position probes are used, then device complexity is reduced, but adaptability to electrode terminal tilting deteriorates
Solution Approach 1:
Instead of complex active adjustment mechanisms, the probe uses a passive flexible guide rod that automatically adapts to tilting through its inherent flexibility. This simple dynamic structure achieves adaptability without significantly increasing device complexity.
Solution Approach 2:
The guide rod incorporates flexible sections or thin-walled structures that can bend and deform to accommodate tilting of the electrode terminal. This flexible design provides adaptability while maintaining relatively simple construction.
