Solution Overview
Problem
Existing electrode drying methods struggle to maintain consistent dryness levels in real-time, leading to deviations in product quality and making it difficult to adjust drying conditions in a roll-to-roll production process.
Innovation Solution
A system and method for automatically controlling electrode drying by periodically collecting information on the dried amount, such as solid content and surface temperature, and using this data to adjust the drying intensity of the oven in real-time, ensuring consistent dryness levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If real-time monitoring and automatic control of drying process is implemented, then manufacturing precision of electrode dryness is improved, but device complexity increases
Solution Approach 1:
The patent implements a feedback control system where a sensor detects the dried amount of the electrode in real-time, and the controller adjusts the drying intensity based on this feedback. The sensor output signal is fed back to the controller, which automatically modifies the drying process to maintain consistent dryness, resolving the contradiction between improved precision and increased complexity through intelligent control.
Solution Approach 2:
The patent replaces manual measurement and adjustment methods with automated sensing and control systems. Instead of physically measuring electrode dryness after drying and manually adjusting parameters, the system uses sensors to detect dried amount and automatically controls the drying intensity, substituting mechanical/manual operations with automated electro-optical control to achieve precision while managing complexity.
2Productivity
If manual measurement and adjustment of drying conditions is used, then device complexity is reduced, but productivity decreases due to time-consuming measurements
Solution Approach 1:
The patent enables continuous monitoring and control of the drying process through real-time detection of the electrode's dried amount. The sensor continuously measures the drying state, and the controller continuously adjusts the drying intensity without interrupting the production flow, maintaining continuous useful action throughout the process to maximize productivity while managing complexity through automation.
Solution Approach 2:
The drying system performs self-adjustment based on sensor feedback, eliminating the need for external manual measurement and adjustment operations. The controller automatically modifies drying conditions in response to sensor signals, allowing the system to serve itself and maintain optimal drying parameters continuously, thereby improving productivity without requiring additional manual labor or complex external control systems.
