Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrode sheet deviation correction schemes only address deviations in the unwinding direction, failing to effectively correct deviations in multiple directions, which affects the performance and stability of the electrode sheet.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If only deviation in the unwinding direction is corrected, then the correction process is simple, but the deviation correction is incomplete and electrode sheet performance deteriorates
Solution Approach 1:
The patent extends the correction approach from one dimension (unwinding direction) to two dimensions by adding correction in the vertical direction. The correction device includes first and second driving components that can independently adjust the electrode sheet position in both the unwinding direction and the vertical direction, enabling comprehensive two-dimensional deviation correction.
2Manufacturing precision
If deviation correction is extended to multiple directions, then the electrode sheet performance is improved, but the device complexity increases
Solution Approach 1:
The patent integrates multiple correction functions into a single unified correction device. The correction device combines first and second driving components with first and second guide components, all controlled by a single control device, to perform both unwinding-direction and vertical-direction corrections simultaneously, reducing overall system complexity.
Solution Approach 2:
The correction device is designed as a multi-functional system that can correct deviations in multiple directions (unwinding direction and vertical direction) using a single integrated apparatus. The driving components and guide components work together to provide comprehensive correction capabilities, making the device universally applicable for various deviation scenarios.
