Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If chlorine is used to kill harmful bacteria, algae and fungus in the water, then water safety is improved, but strong chlorine odor permeates the area and attacks plastics and fibers causing deterioration
Solution Approach 1:
The patent changes the chemical composition parameters of the filter medium by incorporating copper and zinc alloys particles with specific grain sizes (0.5-5.0 mm) in controlled proportions. This compositional parameter change enables the filter to achieve water purification through electrochemical reactions rather than chlorine-based disinfection, thereby eliminating chlorine odor and material degradation while maintaining water safety.
Solution Approach 2:
The filter medium is constructed as a composite material system combining copper alloy particles, zinc alloy particles, and a structural support matrix. This composite structure leverages the antimicrobial properties of copper and zinc while the supporting matrix provides mechanical integrity. The synergistic interaction between different materials enables effective pathogen elimination without requiring chlorine, thus resolving the contradiction between water safety and harmful chlorine effects.
2Reliability
If particulate filter is used to trap and remove particulate contaminants from water, then water filtration is improved, but the filter must be periodically back-flushed requiring the filter system to be taken down
Solution Approach 1:
The filter medium performs self-cleaning through its electrochemical properties. The copper and zinc alloy particles continuously generate electrochemical reactions that prevent organic matter and particulate contaminants from adhering to the filter structure. This self-service mechanism eliminates the need for periodic back-flushing and system disassembly, as the filter automatically prevents fouling without requiring manual intervention or shutdown.
Solution Approach 2:
The patent replaces the mechanical back-flushing system with an electrochemical self-cleaning mechanism. Instead of using mechanical force (water pressure) to remove accumulated debris through back-flushing, the system uses electrochemical reactions at the particle level to prevent contaminant accumulation in the first place. This substitution eliminates the complex mechanical back-flush infrastructure and simplifies operation.
