Optical Measurement System Assembly Error Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing optical measurement systems face challenges in detecting assembly errors and stray light issues without inserting a test sample carrier, which is necessary for immediate use in a dark space environment.
Innovation Solution
A measurement system comprising a first element (holder) with a test sample carrier, a second element (casing), an imaging section, and an analysis section that captures and analyzes verification images to detect assembly errors and stray light without inserting the test sample carrier.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a test sample carrier is inserted to check assembly errors, then assembly errors can be detected, but the test sample carrier cannot be used immediately and measurement time is lost
Solution Approach 1:
The patent performs assembly error detection before inserting the test sample carrier by capturing an image of the measurement region without the carrier. This preliminary action allows verification of correct assembly and detection of stray light issues before the actual measurement process begins, eliminating the need to set aside already-opened test strips for testing purposes.
2Ease of manufacture
If the measurement device is assembled by users themselves, then ease of manufacture and deployment is improved, but assembly errors may occur
Solution Approach 1:
The patent implements a feedback mechanism where the imaging section captures images of the measurement region, and the analysis section automatically analyzes these images to detect assembly errors. This feedback loop provides immediate verification to users about the correctness of their assembly, allowing them to correct mistakes before actual measurements are performed.
3Measurement precision
If extraneous stray light is present in the measurement area, then measurement accuracy deteriorates, but detecting stray light requires additional testing steps
Solution Approach 1:
The patent makes the imaging section serve multiple functions: it captures images for assembly verification and simultaneously detects the presence of extraneous stray light in the measurement region. By integrating these detection capabilities into the existing imaging system rather than adding separate testing devices, the patent maintains measurement precision while avoiding increased device complexity.
