Colorimeter Speed Feedback for Measurement Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Inexperienced users may fail in color measurement due to uncertainty about proper methods when using a colorimeter, as existing technologies lack effective assistance for manual color measurement processes.
Innovation Solution
A non-transitory computer-readable storage medium storing a program that assists users by presenting the difference between actual and ideal moving speeds of a colorimeter during color measurement, along with a control device that prints a color chart sheet and performs color adjustment based on measurement results.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual color measurement is performed without guidance, then operation simplicity is maintained, but measurement precision deteriorates due to user inexperience
Solution Approach 1:
The system provides real-time feedback by displaying the difference between actual moving speed and ideal moving speed to the user during color measurement. This feedback mechanism guides inexperienced users to maintain the proper moving speed, thereby improving measurement precision without increasing operational complexity
Solution Approach 2:
The control device acts as an intermediary between the user and the color measurement process. It monitors the moving speed of the colorimeter and provides guidance information, serving as a mediator that helps inexperienced users achieve accurate measurements without requiring them to understand complex measurement techniques
2Measurement precision
If real-time speed monitoring and feedback are added to assist users, then measurement precision improves, but device complexity increases
Solution Approach 1:
The control device performs multiple functions: it controls the presenting unit, monitors moving speed, calculates speed differences, and provides feedback. By making the control device multi-functional, the system avoids adding separate complex monitoring equipment, thereby improving measurement precision while minimizing the increase in device complexity
Solution Approach 2:
The system uses the existing control device to monitor and analyze the moving speed of the colorimeter itself, rather than requiring external monitoring equipment. The control device leverages its own computational resources to provide speed feedback, reducing overall system complexity while improving measurement accuracy

AI summary
A PC presents, to a user, a difference between an actual speed and an ideal speed, the actual speed being a moving speed of a colorimeter when the user moves the colorimeter with respect to a color chart, the ideal speed being a moving speed of the colorimeter ideal for color measurement on the color chart.
