Electrode Lead Gripper Geometry for Twist-Free Battery Lead Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electrode lead grippers cause twisting of electrode leads due to changes in pressure or surface friction, leading to dimensional defects in batteries during transportation.
Innovation Solution
A lead gripper with upper and lower arms featuring lead fixing protrusions and grooves that securely grip the electrode lead, preventing twisting by engaging the lead through holes or protrusions and accommodating them in grooves, allowing for stable transportation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a flat gripper is used to grip a flat electrode lead, then the gripping structure is simple, but the electrode lead twists during transportation due to pressure or friction changes
Solution Approach 1:
The gripper surface is designed with a curved shape instead of a flat surface. The curved gripper surface conforms to the cylindrical shape of the electrode lead, distributing pressure evenly and preventing twisting during transportation while maintaining structural simplicity.
2Force
If pressure is applied to grip the electrode lead, then the electrode lead is held securely, but twisting occurs due to pressure or friction changes
Solution Approach 1:
The curved gripper surface distributes the gripping force evenly around the cylindrical electrode lead, preventing localized pressure points that cause twisting. This maintains secure holding while preserving positioning accuracy.
3Force
If friction is increased to prevent slipping, then the electrode lead is held more securely, but twisting occurs due to friction changes
Solution Approach 1:
The curved gripper surface increases contact area with the cylindrical electrode lead, distributing friction forces evenly. This prevents localized friction-induced twisting while maintaining secure grip through increased overall friction.
