Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for analyzing malodorous components generated by microorganisms in superabsorbent polymers lack the ability to simultaneously and accurately quantify both ammonia and multi-odor components, and are hindered by reproducibility issues due to separate analysis of each component.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If separate analysis is conducted for each malodorous component (ammonia and multi-odor components), then the analysis can be performed using conventional methods, but the productivity is reduced and reproducibility is hindered
Solution Approach 1:
The gas collection system is segmented into multiple parallel collection units, each dedicated to collecting specific malodorous components (ammonia in one unit, multi-odor components in another unit). This segmentation allows simultaneous collection of different components through separate flow paths while maintaining a unified culture flask, thereby improving both productivity and reproducibility
Solution Approach 2:
The patent merges multiple collection functions into a single integrated system where multiple collecting units are connected in parallel to one culture flask. This combination enables simultaneous analysis of multiple components in one experimental setup, eliminating the need for separate experiments and improving both efficiency and reproducibility
2Measurement precision
If gas collection is performed without independent flow control, then the device complexity is reduced, but the measurement precision of each component is compromised
Solution Approach 1:
The system incorporates adjustable flow control valves in each parallel flow path, enabling dynamic adjustment of gas flow rates to each collecting unit. This allows optimization of collection conditions for different components (ammonia and multi-odor components) independently, ensuring accurate quantitative analysis while maintaining a manageable system structure through localized control
