Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods fail to measure and maintain a large amount of dissolved oxygen in a solution that remains stable even when heated, as the oxygen clathrate hydrate form is not detectable by existing measurement methods.
Innovation Solution
A new dissolved oxygen measurement method involving a deoxidizing amino compound, such as carbohydrazide, is used to measure the difference in oxygen concentration before and after heating, allowing for the detection of oxygen clathrate hydrates containing 50 ppm or more of dissolved oxygen, which is stable up to 100°C.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional measurement methods are used, then the measurement process is simple, but the dissolved oxygen in oxygen clathrate hydrate cannot be detected
Solution Approach 1:
The patent introduces a deoxidizing amino compound as an intermediary substance that reacts with dissolved oxygen in the oxygen clathrate hydrate. This intermediary enables the detection of previously undetectable dissolved oxygen by converting it into a measurable form through chemical reaction, thereby resolving the contradiction between measurement precision and device complexity.
Solution Approach 2:
The patent changes the measurement parameter from direct physical detection to chemical reaction-based detection. By transforming the measurement approach from physical measurement to chemical analysis using deoxidizing amino compounds, the system can detect dissolved oxygen in oxygen clathrate hydrate that was invisible to conventional measurement methods.
2Stability of the object's composition
If oxygen is dissolved in water using conventional methods, then the process is straightforward, but the dissolved oxygen is released when heated
Solution Approach 1:
The patent utilizes the phase transition properties of oxygen clathrate hydrate formation and decomposition. By controlling the formation of oxygen clathrate hydrate through specific dissolution conditions, the system achieves stable oxygen retention that persists through heating, leveraging phase transition mechanisms to maintain oxygen in dissolved state.
Solution Approach 2:
The patent creates a composite system involving oxygen clathrate hydrate structures within water. This composite material approach allows oxygen to be trapped in a stable crystalline framework that resists release upon heating, achieving both stability and manufacturability through the formation of this unique composite structure.
3Measurement precision
If a new measurement method with deoxidizing amino compound is used, then dissolved oxygen in oxygen clathrate hydrate can be measured, but the measurement process becomes more complex
Solution Approach 1:
The deoxidizing amino compound serves as a measurable intermediary that quantifies the dissolved oxygen indirectly. By measuring the consumption of this intermediary substance during the reaction with dissolved oxygen, the system achieves accurate quantification of oxygen in oxygen clathrate hydrate, resolving the measurement precision versus complexity contradiction.
Solution Approach 2:
The patent replaces complex physical measurement systems with a simpler chemical reaction-based measurement approach. By substituting physical detection mechanisms with chemical analysis using deoxidizing amino compounds, the system achieves precise oxygen quantification through more straightforward chemical measurements rather than complex physical instrumentation.
