Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If anti-fouling paints or coatings containing TBT or TPT are used, then the prevention of marine organism adhesion is effective, but toxins are released into the water causing environmental damage
Solution Approach 1:
The patent replaces chemical anti-fouling systems with an electrical field-based system. A power supply device generates electrical signals that are transmitted through water to the substrate surface, creating an electrical field that prevents marine organism adhesion without releasing toxins into the environment.
Solution Approach 2:
The patent changes the fundamental parameter of anti-fouling from chemical concentration to electrical field strength. By controlling the voltage and frequency of electrical signals applied to the substrate, the system achieves effective fouling prevention while eliminating toxic substance release into the water.
2Reliability
If copper and derivative compounds are used in paints, then anti-fouling performance is improved, but safety concerns arise due to potential toxicity
Solution Approach 1:
The patent substitutes electrical field application for copper-based chemical treatments. The electrical signals prevent marine organism attachment through non-chemical means, eliminating copper toxicity concerns while maintaining effective anti-fouling performance.
3Reliability
If bio-dispersants are used to control biofouling, then marine organism accumulation is reduced, but the solution requires complex chemical applications
Solution Approach 1:
The patent replaces complex chemical bio-dispersant applications with a simple electrical field system. A power supply device connected to the substrate generates electrical signals that continuously prevent biofouling without requiring chemical mixing, application, or monitoring procedures.
