Battery Electrode Overhang Measurement Using Dynamic Edge Regions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing overhang measurement technologies for battery electrode sheets rely on fixed-area linear fitting, limiting flexibility and adaptability, making them unsuitable for online measurements and complex environments.
Innovation Solution
Determine the location of electrode sheet edges based on dynamically determined areas, rather than fixed areas, allowing for flexible positioning and improved adaptability in overhang measurement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If fixed-area linear fitting solution is used to position electrode sheet edges, then the measurement process is simple, but the flexibility and adaptability are poor
Solution Approach 1:
The patent transforms the static fixed-area approach into a dynamic adaptive area determination process. The system dynamically determines the area where each electrode sheet edge is located based on image content and positioning requirements, rather than using predetermined fixed areas. This dynamic adaptation enables the measurement system to flexibly adjust to different electrode sheet configurations and complex environments while maintaining measurement accuracy.
2Ease of operation
If fixed area positioning mode is adopted, then the measurement method is easy to implement, but it cannot be applied to complex environments
Solution Approach 1:
The patent changes the parameter of measurement area from fixed to dynamically determined. By adjusting the area parameters based on actual image content and electrode sheet positions, the system maintains implementation simplicity while gaining the ability to adapt to complex environments. The dynamic area determination allows the measurement method to respond to varying environmental conditions and electrode sheet arrangements.
