Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sample analyzers require a separate light source for optical measurements, leading to increased device size and reduced reliability due to differences in light quality, which can result in unnecessary disposal of serum samples.
Innovation Solution
A sample analyzer with a single light source section that illuminates both the sample and the measurement specimen, using a lamp unit with collective lenses and optical filters to provide light of multiple wavelengths for both first and second optical information acquiring sections, ensuring consistent light quality and reducing the need for separate light sources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate light source is provided for illuminating the serum sample in the clinical analysis device, then the optical measurement (main measurement) can be performed, but the device size is enlarged
Solution Approach 1:
The patent merges the light source for probe measurement and the light source for clinical analysis device measurement into a single integrated light source. The light source unit includes a light source and a condenser lens that collectively illuminate both the serum sample in the needle and the serum sample in the container, eliminating the need for separate light sources and reducing device size while maintaining measurement reliability
Solution Approach 2:
The light source is designed to serve multiple functions: it illuminates the serum sample in the needle for initial assessment and also illuminates the serum sample in the container for main measurement. This multi-functional light source reduces the number of components needed while ensuring consistent illumination quality across different measurement stages
2Measurement precision
If a separate light source is provided for illuminating the serum sample in the clinical analysis device, then the optical measurement can be performed, but the light quality differs from the probe measurement light, reducing estimation reliability
Solution Approach 1:
The patent combines both illumination functions into a single light source system, ensuring that the same light quality is used for both probe measurement and clinical analysis device measurement. This eliminates the problem of different light qualities causing unreliable estimations
Solution Approach 2:
The light source is designed to provide homogeneous light quality for both measurement stages. The condenser lens focuses light uniformly onto both the needle sample and container sample, ensuring consistent illumination characteristics and improving the reliability of estimation based on probe measurement results
