Test Strip Imaging with Switched Light Sources for Dual Regions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing measurement systems struggle to perform appropriate imaging on test strips with multiple imaging regions, as they exclusively use different images from plural light sources for a single imaging region.
Innovation Solution
A measurement system and method that includes an insertion gate, holder, housing, and smart device with a camera and illuminator, where the illuminator is turned off during imaging of one region and the measurement light source is turned on during imaging of another region, allowing appropriate imaging based on the specific needs of each region.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If plural light sources are used to image multiple regions, then image quality is improved, but light source exhaustion occurs and efficiency deteriorates
Solution Approach 1:
The patent divides the test strip into multiple imaging regions (first imaging region and second imaging region) and assigns different light sources to each region. The measurement light source illuminates only the first imaging region while the illuminator handles the second imaging region, preventing unnecessary exhaustion of the measurement light source and improving overall system efficiency.
2Adaptability or versatility
If different light sources are used for different regions, then appropriate imaging is achieved, but device complexity increases
Solution Approach 1:
The patent employs a controller that manages multiple light sources (measurement light source and illuminator) to serve different imaging regions. This multi-functional approach allows a single system to handle both measurement imaging and identification imaging with appropriate light sources, achieving adaptability without proportionally increasing complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables effective imaging of multiple regions on a test strip by using the appropriate light source for each region, preventing exhaustion of the measurement light source and improving image quality.
Implementation Method 1
a measurement light source provided at a position to irradiate the first region of the test strip accommodated in the holder
Implementation Method 2
an illuminator that illuminates the second region of the test strip accommodated in the holder
Implementation Method 3
including a camera that images the first region and the second region

AI summary
A measurement system including: an insertion gate into which a test strip including first and second regions is inserted; a holder accommodating the test strip; a housing including a window facing the test strip; and a smart device including an illuminator illuminating the second region and including a camera imaging the first and second regions, in which the housing includes a mounting part placing the smart device on an outer surface of the housing in a state in which the camera and the illuminator are disposed at positions facing the window, and a measurement light source provided at a position to irradiate the first region, and in a case in which the camera images the first region, the illuminator is turned off while the measurement light source is turned on, and in a case in which the camera images the second region, the illuminator is turned on.
