Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual positioning and marking methods are used to determine detection device installation positions, then the process is simple to implement, but the measurement precision and manufacturing precision deteriorate due to installation errors and manual marking variations
Solution Approach 1:
The patent replaces manual mechanical positioning and marking methods with an automated optical detection system. The detection device uses optical fields to automatically detect reference markers on the measurement object and calculate inter-device distances, eliminating manual intervention and improving positioning accuracy without significantly increasing system complexity.
Solution Approach 2:
The detection device performs self-positioning by automatically detecting reference markers and calculating its own installation position relative to other detection devices. This self-service capability eliminates the need for manual positioning and marking processes, improving both accuracy and efficiency.
2Manufacturing precision
If automated detection methods are implemented to determine installation positions, then measurement precision improves, but the device complexity and process complexity increase
Solution Approach 1:
The detection device is designed with multi-functionality, serving both as a coating amount measurement instrument and as a self-positioning system. By integrating reference marker detection and inter-device distance calculation capabilities into the existing detection device, the patent achieves improved manufacturing precision without adding separate positioning systems, thereby limiting the increase in device complexity.
3Productivity
If manual marking processes are used to align detection devices, then the process is easy to operate, but productivity decreases and measurement precision deteriorates due to manual intervention variations
Solution Approach 1:
The patent replaces manual marking operations with automated optical detection and calculation processes. The detection device automatically detects reference markers, calculates inter-device distances, and determines installation positions without manual intervention, significantly improving productivity while maintaining ease of operation through automated processes.
Solution Approach 2:
The system implements feedback by using detected reference marker positions to calculate and adjust inter-device distances. This closed-loop approach automatically corrects positioning variations and improves both productivity and measurement precision without requiring complex manual operations.

AI summary
A measurement device (10) collects, from each of detection devices (20) installed in a conveyance direction of a measurement object having a reference marker (M), each of detection results of the reference marker (M) detected by the respective detection devices (20), and calculates, based on the collected detection results, an inter-device distance that indicates an interval at which each of the detection devices (20) is installed.
