Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional evaporation concentration mechanisms in automatic analyzers fail to simultaneously process multiple samples while individually controlling each sample's evaporation concentration according to its characteristics.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single decompression source is used for multiple samples, then device complexity is reduced, but individual control of evaporation concentration for each sample cannot be achieved
Solution Approach 1:
The patent divides the decompression system into multiple independent flow paths (first flow path and second flow path), each with its own decompression valve (first decompression valve and second decompression valve). This segmentation allows each sample to be controlled independently while sharing a common decompression source, resolving the contradiction between device simplicity and individual control capability.
2Productivity
If evaporation concentration is performed on multiple samples simultaneously, then productivity increases, but individual control according to sample characteristics cannot be achieved
Solution Approach 1:
The patent implements separate flow paths and decompression valves for each sample, enabling simultaneous processing of multiple samples while maintaining independent control over each sample's evaporation concentration parameters according to its specific characteristics.
3Measurement precision
If decompression speed is controlled to prevent bumping, then analysis precision is improved, but processing time increases
Solution Approach 1:
The patent employs decompression valves that can dynamically adjust the decompression speed for each sample based on its specific requirements. This dynamic control allows the system to optimize the balance between preventing bumping (for accurate analysis) and maintaining efficient processing time for each individual sample.
