Spectroscope Measurement Error Detection and Automatic Repositioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing measurement devices require manual repositioning to correct measurement errors in color patches, which is inefficient and challenging when coordinate information is lacking, especially when multiple patches with measurement errors need re-measurement.
Innovation Solution
A measurement device with a spectroscope and movement mechanism that detects measurement errors by monitoring light variations, allowing for automatic repositioning to the error location during the measurement process, using a specific wavelength for initial measurement and switching wavelengths for spectroscopic analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual repositioning is used to correct measurement errors, then measurement accuracy can be improved, but measurement time and operational complexity increase significantly
Solution Approach 1:
The measurement device automatically detects measurement errors and repositions itself without manual intervention. The control unit monitors measurement results and autonomously adjusts the spectroscope position to areas with measurement errors, enabling the system to correct its own mistakes and eliminating the need for manual repositioning.
Solution Approach 2:
The system implements a feedback mechanism where measurement results are continuously monitored and used to control subsequent actions. When a measurement error is detected, the control unit receives this feedback and automatically repositions the spectroscope to the problematic area for re-measurement, creating a closed-loop control system that improves accuracy while maintaining efficiency.
2Measurement precision
If manual repositioning is used to correct measurement errors, then measurement accuracy can be improved, but operational complexity increases due to lack of coordinate information
Solution Approach 1:
The system replaces manual mechanical positioning with an automated control system. Instead of requiring operators to manually move the spectroscope based on coordinate information, the control unit automatically controls the movement mechanism to reposition the spectroscope to areas with measurement errors, eliminating the need for coordinate information and simplifying operation.
Solution Approach 2:
The measurement device autonomously identifies and relocates to measurement error areas without requiring external coordination information. The system serves itself by using its own measurement data to guide repositioning, making the operation simple and intuitive regardless of whether coordinate information is available.
3Measurement precision
If all color patches are measured before displaying errors, then comprehensive measurement coverage is achieved, but productivity decreases due to sequential processing
Solution Approach 1:
The system performs preliminary measurements of all color patches to identify areas with measurement errors before final processing. By detecting errors early and enabling automatic repositioning, the system can efficiently target only problematic areas for re-measurement rather than sequentially processing all patches, thereby improving throughput while maintaining measurement completeness.
Solution Approach 2:
The control unit continuously monitors measurement results and identifies areas with measurement errors. This feedback enables the system to prioritize re-measurement of only the problematic patches rather than requiring sequential measurement of all patches, improving productivity by reducing unnecessary re-measurements while ensuring comprehensive coverage of error-prone areas.

AI summary
Provided is a measurement device including a spectroscope, a movement mechanism configured to relatively move the spectroscope along a first direction with respect to the measurement target, and one or more processors configured to execute detecting a measurement error indicating that spectroscopic measurement processing by the spectroscope is not executed normally, and controlling the spectroscope and the movement mechanism, in which the one or more processors, when the measurement target is a plurality of color patches arranged along the first direction, cause the spectroscope to execute first measurement processing of measuring light with a specific wavelength set in advance while relatively moving the spectroscope in the first direction to acquire a measured value with respect to the specific wavelength obtained by the first measurement processing and a position of the spectroscope, and when the measurement error is detected, move the spectroscope to a position where an amount of variation of the measured value is greater than or equal to a threshold value in a second direction opposite to the first direction and then move the spectroscope in the first direction.
