Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional oxygen detectors lose their ability to detect oxygen effectively at high temperatures due to browning of reducing saccharides, leading to unclear color changes and slow response times, which is exacerbated by the use of monosaccharides with high reactivity.
Innovation Solution
Incorporating a reducing trisaccharide as a second component alongside a monosaccharide and disaccharide in the oxygen indicator aqueous solution, which stabilizes the reducing saccharides and prevents browning, allowing the oxygen detector to maintain its functionality at room temperature and high temperatures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If monosaccharides are used as reducing saccharides to maintain redox dye in reduced state, then oxygen detection ability is improved, but browning occurs at high temperature causing unclear color changes
Solution Approach 1:
The patent combines monosaccharides and disaccharides as reducing saccharides in the oxygen detector. This combination allows the system to benefit from the high reducing power of monosaccharides while the disaccharides provide thermal stability and prevent browning at high temperatures, thus resolving the contradiction between detection ability and heat resistance.
Solution Approach 2:
The patent uses a composite system of multiple saccharide types (monosaccharides and disaccharides) working together. This composite approach leverages the complementary properties of different saccharides: monosaccharides provide strong reducing capability while disaccharides provide thermal stability, creating a synergistic effect that overcomes the limitations of single-component systems.
2Reliability
If monosaccharides are used as reducing saccharides due to high reducing power, then redox dye is effectively reduced, but reactivity increases causing rapid browning at high temperature
Solution Approach 1:
The patent merges monosaccharides and disaccharides in the reducing saccharide component. The monosaccharides provide the necessary reducing power for effective redox dye reduction, while the disaccharides act as thermal stabilizers that slow down browning reactions at high temperatures, thus balancing reduction efficiency with reaction speed control.
Solution Approach 2:
The patent changes the compositional parameter of the reducing saccharide system from single-component (monosaccharide) to multi-component (monosaccharide + disaccharide). This parameter change modifies the overall reactivity profile of the system, providing both high reducing power and reduced thermal reactivity through the combined effects of different saccharide types.
3Reliability
If reducing saccharides are stored at low temperature to prevent browning, then detection ability is maintained, but storage cost increases
Solution Approach 1:
The patent combines monosaccharides and disaccharides to create a reducing saccharide system that is stable at room temperature. This combination eliminates the need for low-temperature storage while maintaining detection ability, as the disaccharide component prevents browning even at elevated temperatures, thus resolving the contradiction between maintaining reliability and storage temperature requirements.
4Reliability
If reducing saccharide reacts with basic substance to form chain structure, then redox dye is reduced, but decomposition occurs at high temperature reducing detection ability
Solution Approach 1:
The patent merges monosaccharides and disaccharides in the reducing saccharide component. The monosaccharides form the necessary chain structures with basic substances to reduce redox dye, while the disaccharides provide structural stability that prevents decomposition at high temperatures, thus resolving the contradiction between redox dye reduction and structural stability.

The oxygen detector exhibits high heat resistance, maintaining clear and quick color changes in response to oxygen levels, reducing storage costs and ensuring effective oxygen detection across varying temperatures.
Implementation Method 1
The reducing saccharide is ring-opened in the oxygen indicator aqueous solution adjusted to be basic by the basic substance and forms a chain structure having a reducing group (an aldehyde group or a ketone group), which reduces the redox dye
Implementation Method 2
When the redox dye maintained in the reduced state is oxidized by oxygen in the atmosphere, the redox dye changes the color
Implementation Method 3
The reducing saccharide is ring-opened in the oxygen indicator aqueous solution adjusted to be basic by the basic substance
