Reflector-Based Optical Measurement for Faster Diagnostic Testing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Diagnostic tests often require specialized laboratory equipment and take a long time to perform, limiting their accessibility and efficiency.
Innovation Solution
A measurement system comprising a light source, reflector, and receiver that allows for faster analysis by emitting light through a measurement subject twice, with the reflector reflecting the light back to enhance data collection efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional diagnostic testing methods are used, then measurement accuracy can be maintained, but the testing time is long and equipment complexity is high
Solution Approach 1:
The patent divides the measurement system into distinct functional components: a light source module, a reflector module, and a detector module. This segmentation allows each component to be optimized independently and simplifies the overall system architecture, enabling faster testing without requiring complex integrated laboratory equipment
Solution Approach 2:
Instead of using complex spectroscopic analysis methods that require sophisticated equipment, the patent inverts the approach by using simple reflectance measurements with basic light sources and detectors. This inversion of the measurement paradigm achieves rapid diagnostics while minimizing equipment complexity
2Measurement precision
If light passes through the measurement subject only once, then the measurement process is faster, but the data quality and measurement precision are reduced
Solution Approach 1:
The patent implements continuous light circulation where light passes through the measurement subject multiple times in sequence without interruption. The reflector redirects light back through the sample, creating multiple measurement interactions within a single continuous operation, thereby improving data quality without proportionally increasing measurement time
Solution Approach 2:
The measurement system serves multiple functions: it performs both qualitative and quantitative analysis, and can measure different properties (absorbance, reflectance, transmittance) using the same optical path and components. This multi-functionality allows enhanced measurement precision without requiring multiple separate measurement cycles
