Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional electrodes are used for chlorine species detection, then detection capability is achieved, but cost is high and performance is low
Solution Approach 1:
The patent changes the material parameters of the electrode by coating pseudo-graphite onto the electrode substrate surface. This material parameter change transforms the electrode from conventional materials to pseudo-graphite, achieving high performance detection with lower cost compared to traditional expensive electrodes
Solution Approach 2:
The patent creates a composite structure by coating pseudo-graphite layer onto an electrode substrate. This composite material approach combines the advantages of the substrate with the superior electrochemical properties of pseudo-graphite, achieving both cost-effectiveness and high detection performance
2Reliability
If conventional electrodes are used for chlorine species detection, then detection function is provided, but electrode fouling occurs and performance is reduced
Solution Approach 1:
The patent changes the surface properties of the electrode by using pseudo-graphite coating, which has inherent anti-fouling characteristics. This parameter change in material composition prevents fouling accumulation and maintains stable detection performance over time
Solution Approach 2:
The patent employs a disposable pseudo-graphite coated electrode that can be replaced when fouling occurs. This approach is more economical than maintaining and regenerating expensive conventional electrodes, achieving cost-effective solution for electrodes that experience fouling
3Measurement precision
If conventional electrodes are used for chlorine species detection, then basic detection is achieved, but environmental interferences affect performance
Solution Approach 1:
The patent changes the electrochemical parameters of the electrode by using pseudo-graphite material, which provides superior resistance to environmental interferences such as dissolved oxygen and other species. This parameter change enables accurate detection of chlorine species even in complex environmental conditions
Solution Approach 2:
The pseudo-graphite coating acts as an intermediary layer between the electrode substrate and the sample solution. This intermediary provides a stable platform that is insensitive to environmental interferences while maintaining high sensitivity to chlorine species detection
