Engineering Contradiction Analysis
1Measurement precision
If skilled operators perform calibration at each production location, then calibration accuracy is maintained, but operational complexity and time consumption increase
Solution Approach 1:
The optical coating apparatus automatically performs calibration by measuring spectral data of test coatings, comparing it to target specifications, and adjusting operation parameters without requiring skilled operators to manually perform multiple setup and configuration steps
Solution Approach 2:
The system pre-stores target spectral data and calibration algorithms in its memory, allowing rapid automated calibration by comparing measured spectral data against pre-programmed specifications without requiring operators to prepare calibration parameters manually
2Measurement precision
If skilled operators perform calibration at each production location, then calibration quality is maintained, but device complexity increases
Solution Approach 1:
The apparatus autonomously performs the complete calibration process including measuring spectral data, comparing it to target specifications, calculating deviations, and adjusting operation parameters without human intervention
Solution Approach 2:
Manual operator actions for calibration are replaced by an automated control system that uses spectral measurement and computer-controlled parameter adjustment, eliminating the need for skilled operators to perform complex manual calibration procedures

If on-site skilled operators are required for calibration, then calibration expertise is available, but productivity decreases
Solution Approach 1:
The system performs self-calibration without requiring skilled operators, eliminating the bottleneck where production must pause for manual calibration and where skilled personnel are needed at each location
Solution Approach 2:
The apparatus continuously measures spectral data of test coatings, compares it to target specifications, and automatically adjusts operation parameters based on the measured deviations, creating a closed-loop system that maintains calibration without human intervention
4Manufacturing precision
If multiple setup and configuration steps are performed manually, then calibration thoroughness is ensured, but ease of operation deteriorates
Solution Approach 1:
The apparatus automatically executes the complete calibration sequence including spectral measurement, data comparison, deviation calculation, and parameter adjustment without requiring operators to manually perform multiple setup and configuration steps
Solution Approach 2:
The complex calibration procedures are extracted from manual operator actions and implemented as automated software routines within the apparatus control system, separating the calibration function from operator intervention
