Solution Approach 1:

The patent implements a closed-loop feedback system where process parameters are continuously monitored in real-time, deviations from target values are automatically detected, and corrective actions are triggered. This eliminates the time delay inherent in manual monitoring and prevents human errors by automating the detection and response mechanism.

Inventive Principle:

Solution Approach 2:

The patent replaces manual mechanical monitoring with an automated electronic control system that uses sensors, processors, and actuators. This substitution enables continuous real-time monitoring without human intervention, significantly reducing detection time and improving reliability through consistent automated operation.

Inventive Principle:
