Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery cell terrace alignment devices lack precision in aligning pouch-type battery cells for cutting the edge of the terrace, and they fail to prevent upward and downward movements during the cutting process.
Innovation Solution
A battery cell terrace alignment device that uses a base part with support components, a table with vacuum pads for stable support, and alignment blocks that correspond in shape to the electrode and terrace of the battery cell, allowing for precise alignment and stabilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a conventional alignment device is used, then the device structure is simple, but the alignment precision of the battery cell is insufficient
Solution Approach 1:
The alignment device is divided into multiple independent alignment blocks (first alignment block, second alignment block, third alignment block, fourth alignment block) that can be adjusted separately. Each alignment block corresponds to a specific region of the battery cell (electrode and terrace), allowing precise positioning without requiring a completely complex integrated structure.
Solution Approach 2:
The alignment blocks are configured to contact the battery cell at multiple spatial dimensions - the first and second alignment blocks contact the electrode area while the third and fourth alignment blocks contact the terrace area. This multi-dimensional contact approach achieves high alignment precision without overly complicating the overall device structure.
2Reliability
If the battery cell is not firmly supported, then the device operation is simple, but the battery cell experiences upward and downward movements during cutting
Solution Approach 1:
The support function is integrated into the existing alignment blocks rather than adding a separate support mechanism. The alignment blocks serve dual purposes: positioning the battery cell for alignment and providing vertical support to prevent movement during cutting, thereby ensuring reliability without significantly increasing device complexity.
Solution Approach 2:
The alignment blocks act as intermediary elements between the cutting device and the battery cell. They provide a stable contact interface that prevents upward and downward movements during cutting while maintaining the simplicity of the overall support structure.
3Manufacturing precision
If the alignment blocks contact only one part of the battery cell, then the device structure is simple, but the alignment precision is insufficient
Solution Approach 1:
The alignment system is segmented into four distinct alignment blocks, each responsible for contacting a specific region of the battery cell. The first and second alignment blocks contact the electrode area while the third and fourth alignment blocks contact the terrace area, enabling precise alignment without requiring a single complex contact mechanism.
Solution Approach 2:
Each alignment block is designed with specific local characteristics to contact different regions of the battery cell. The alignment blocks have varying contact surfaces and positions tailored to their specific functions - some contact the electrode area while others contact the terrace area, achieving high alignment precision through localized contact points.
