Biological Sample Measurement Device Early Washing Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing biological sample measurement devices face reduced throughput due to the need to determine whether additional washing is necessary after each measurement, often resulting in delayed determination of washing condition changes.
Innovation Solution
A biological sample measurement system that includes a characteristic judgment section to assess the sample before completion, using a urine qualitative measurement device to determine the level of occult blood, and a washing control section to adjust washing conditions based on this assessment, allowing for early determination of necessary washing method changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If additional washing is performed based on measurement results to prevent carry-over, then measurement accuracy is improved, but device throughput is reduced
Solution Approach 1:
The invention performs preliminary judgment of the current sample's concentration using a concentration detection unit before completing the full measurement. Based on this preliminary result, the washing control unit determines in advance whether additional washing is needed for the next sample, allowing the washing decision to be made before the current measurement fully completes, thus preventing throughput reduction.
Solution Approach 2:
The system establishes a feedback loop where the concentration detection unit continuously monitors sample concentration and provides real-time information to the washing control unit. This feedback mechanism enables dynamic adjustment of washing operations based on actual sample characteristics, optimizing both measurement accuracy and throughput by avoiding unnecessary washing steps.
2Reliability
If washing condition changes are determined after measurement completion, then accurate washing decisions are made, but time is lost delaying the next measurement
Solution Approach 1:
The concentration detection unit performs preliminary concentration assessment during the measurement process rather than waiting for completion. This preliminary action provides sufficient information for the washing control unit to determine the appropriate washing conditions in advance, allowing the next measurement cycle to start without delay while maintaining accurate washing decisions.
Solution Approach 2:
The system maintains continuous operation by overlapping the concentration detection and washing decision-making processes with the ongoing measurement. The concentration detection unit operates throughout the measurement cycle, ensuring that washing decisions are always ready when needed, eliminating idle time between measurements while preserving measurement reliability.
