Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing urinalysis systems face inefficiencies in processing large volumes of samples due to the need to change measurement conditions based on qualitative analysis results, particularly in systems combining urinary qualitative and sediment tests, leading to challenges in achieving efficient and reliable multi-step analysis.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If measurement conditions of the urine sediment section are changed between two alternative conditions according to whether an analysis result of the qualitative analysis section is positive or negative, then analysis reliability is improved, but measurement efficiency deteriorates
Solution Approach 1:
The patent applies parameter changes by dividing the urine sediment analysis into multiple measurement stages with different parameters. For samples with positive qualitative analysis results, a first measurement condition is applied with specific parameters (measurement time, sample amount). For samples with negative results, a second measurement condition with different parameters is applied. This dynamic parameter adjustment based on qualitative analysis results optimizes both reliability and efficiency
Solution Approach 2:
The system dynamically adjusts measurement conditions based on real-time analysis results from the qualitative section. The management device automatically determines which measurement condition to apply to the sediment section based on the qualitative analysis outcome, creating a dynamic adaptive measurement system that responds to sample characteristics
2Reliability
If a plurality of analyzers with different measurement methods are used for multi-step analysis, then analysis reliability is improved, but system complexity increases
Solution Approach 1:
The management device serves multiple functions: it manages the qualitative analysis section, controls the sediment analysis section, determines measurement conditions, and coordinates between different analyzers. This universal control system reduces overall system complexity by consolidating management functions in a single device rather than requiring separate control systems for each analyzer
Solution Approach 2:
The management device acts as an intermediary between the qualitative analysis section and the sediment analysis section. It receives results from the first analyzer, processes this information, and determines appropriate measurement conditions for the second analyzer based on the qualitative analysis outcomes, thereby coordinating the multi-step analysis process
3Measurement precision
If sample amount for the second analyzer is increased to improve measurement accuracy, then measurement precision is improved, but reagent consumption and processing time increase
Solution Approach 1:
The patent applies local quality by adjusting the sample amount specifically for the sediment analysis section based on the qualitative analysis results, while keeping other measurement parameters optimized. For positive samples, a larger sample amount is provided to the sediment section to ensure accurate detection of sediment components. For negative samples, a smaller sample amount suffices, reducing processing time and reagent consumption without compromising overall measurement precision
