Colorimeter Measurement Guide With Frame-and-Window Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing colorimetric systems face challenges in accurately aligning a colorimeter with the measurement position of a printed matter, leading to potential position shifts and inappropriate colorimetric results.
Innovation Solution
A measurement guide with a concave portion and translucent sheet material is used to align the opening portion of a colorimetric device with the measurement site, featuring a frame that fits around the device and a window portion aligned with the opening, ensuring precise alignment and easy handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a measurement position presenting guide is used to indicate the measurement region, then the measurement position is presented, but the alignment method for the colorimeter with respect to the opening is not provided, causing position shift and inappropriate colorimetric results
Solution Approach 1:
The patent introduces a measurement guide as an intermediary tool between the colorimeter and the printed matter. The measurement guide includes a frame with a concave portion that receives the colorimeter's bottom portion, and a sheet material with a window portion that aligns with the opening portion. This intermediary structure provides both position indication and alignment guidance, solving the problem of position shift while maintaining ease of operation.
Solution Approach 2:
The patent replaces manual alignment operations with a mechanical guidance system. The concave portion of the frame and the window portion of the sheet material create a mechanical constraint that automatically guides the colorimeter into the correct position and orientation, eliminating the need for complex manual alignment procedures and ensuring consistent positioning.
2Ease of operation
If manual operation is used to bring the colorimeter into contact with the measurement region, then colorimetry can be performed, but position shift occurs and appropriate colorimetric results are not obtained
Solution Approach 1:
The measurement guide serves as a mediator that combines the functions of position indication and alignment guidance. The frame structure with its concave portion and the sheet material with the window portion work together to ensure the colorimeter is positioned correctly during manual operation, maintaining both operational simplicity and measurement precision.
Solution Approach 2:
The measurement guide is prepared in advance with the frame and sheet material configured to provide alignment guidance. The window portion is pre-positioned to align with the opening portion, and the concave portion is pre-formed to receive the colorimeter's bottom portion. This preliminary preparation ensures that when manual operation occurs, the alignment is already established, preventing position shift during the measurement process.

AI summary
A measurement guide is a measurement guide for aligning an opening portion of a colorimetric device with a measurement site of a measurement target, the colorimetric device including the opening portion provided at a bottom portion of a device main body and through which light arriving from the measurement target is introduced into the device main body and an incident light processing unit for processing light entering through the opening portion, the measurement guide including a frame configured to form an outer periphery of a concave portion into which the bottom portion is fitted, and a sheet material having translucency and configured to form a bottom surface of the concave portion, wherein the sheet material has a window portion that aligns with the opening portion when the bottom portion is fitted into the concave portion.
