Pause Resume Circuit for Automated Plasma Coating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual monitoring of multiple plasma coating parameters in aircraft engine part manufacturing is time-consuming, prone to human error, and requires significant labor, as a single operator can only manage a single coating bay, leading to inefficiencies and potential deviations from tolerance.
Innovation Solution
An automated apparatus with a robotic spray unit and multiple sensors, coupled with a controller featuring a pause/resume circuit, which continuously monitors process parameters and automatically pauses or resumes the coating process if parameters fall out of or return to tolerance, allowing a single operator to manage multiple coating booths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual monitoring of coating parameters is performed, then human operators can detect faults, but labor requirements increase and human error may occur
Solution Approach 1:
The system performs self-monitoring and self-correction through automated sensors and pause/resume circuits that detect parameter deviations and adjust the coating process without human intervention, eliminating the need for manual monitoring while maintaining reliability
Solution Approach 2:
Manual monitoring operations are replaced by an automated electronic control system with sensors and programmable logic, substituting human operators with mechanical/electronic systems that provide continuous monitoring without labor requirements
2Reliability
If a single human operator monitors a single coating bay, then continuous monitoring is possible, but labor requirements increase
Solution Approach 1:
The automated monitoring system serves multiple coating bays simultaneously through a centralized control architecture, allowing one system to perform the function of multiple human operators across multiple stations
Solution Approach 2:
Human operators are replaced by automated sensor systems and electronic controllers that provide continuous monitoring capability without the organizational complexity of managing multiple operators and shifts
3Reliability
If manual fault detection and correction is performed, then faults can be identified, but time is lost due to manual intervention
Solution Approach 1:
The system continuously monitors all parameters in advance and automatically detects deviations before they result in defective parts, enabling immediate corrective action that prevents rather than merely responds to faults
Solution Approach 2:
The pause/resume circuits receive continuous feedback from sensors monitoring coating parameters and automatically adjust the process by pausing when deviations occur and resuming when parameters return to specification, creating a closed-loop control system that eliminates manual intervention delays

AI summary
The present disclosure sets forth an automated apparatus and method for applying gas plasma coatings to aircraft engine parts. The process and apparatus employ a plurality of sensors which continually monitor various process parameters associated with the coating process. If any of the measured parameters fall out of tolerance, the coating process is interrupted to allow a user to fix the source of the problem, where upon the process is reengaged. Moreover, the process and apparatus employ a pause resume circuit which uses predetermined durations for pausing and resuming the coating process.
