Solution Overview
Problem
The viscosity of slurry in battery processing often fails to reach a preset standard, affecting the adhesion and quality of coated products, leading to inconsistent battery performance.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the slurry mixing assembly operates continuously without monitoring, then the mixing process is simple and device complexity is low, but the viscosity control precision deteriorates and product quality is affected
Solution Approach 1:
The patent implements a feedback control system where a viscosity sensor continuously monitors the slurry viscosity and sends signals to the controller, which adjusts the mixing assembly operation accordingly. This closed-loop feedback mechanism ensures precise viscosity control while maintaining reasonable device complexity through automated control.
Solution Approach 2:
The patent replaces manual viscosity detection and control methods with automated sensing and control systems. The viscosity sensor and controller substitute for manual measurement and adjustment, improving precision while the automation reduces the need for complex manual intervention systems.
2Measurement precision
If the viscosity monitoring assembly is placed inside the slurry mixing assembly, then real-time monitoring is achieved, but the risk of contamination increases and sealing complexity worsens
Solution Approach 1:
The patent extracts the viscosity monitoring function from the slurry mixing assembly by placing the viscosity sensor in a separate location where slurry is drawn for monitoring and then returned. This separation removes the monitoring assembly from the main mixing environment, eliminating contamination risks while maintaining real-time monitoring capability.
Solution Approach 2:
The patent introduces an intermediary fluid path that allows slurry to be temporarily removed for monitoring and then returned to the mixing assembly. This intermediary pathway enables monitoring without direct exposure of the sensor to the main slurry environment, reducing contamination risk while maintaining measurement accuracy.
3Productivity
If manual viscosity detection is used, then the device structure is simple, but detection efficiency is low and environmental contamination affects measurement accuracy
Solution Approach 1:
The patent replaces manual viscosity detection with an automated viscosity sensor and control system. The sensor continuously monitors viscosity without manual intervention, dramatically improving detection efficiency while the automated system eliminates contamination risks associated with manual sampling and measurement.
Solution Approach 2:
The patent implements continuous viscosity monitoring rather than intermittent manual checks. The viscosity sensor operates continuously, providing real-time data for control adjustments, which improves both detection efficiency and measurement accuracy by eliminating gaps in monitoring where contamination could occur.
