Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If chlorine, bromine, algaecides and other chemicals are used to control bacteria, fungi, algae, then water purification effectiveness is improved, but health hazards to humans increase
Solution Approach 1:
The patent replaces chemical purification methods with an electrolytic system using dissimilar metal particles (such as copper and zinc) that generate electrochemical reactions to purify water. The electrolytic filter uses electrical current to drive redox reactions that kill bacteria, fungi, and algae without introducing harmful chemicals into the water, thus maintaining purification effectiveness while eliminating health hazards associated with chemical use
Solution Approach 2:
The patent changes the fundamental parameter of water purification from chemical-based to electrochemical-based. By using dissimilar metal particles in an electrolytic cell, the system transforms the purification mechanism from direct chemical contact to electrochemical reactions, fundamentally altering how purification is achieved and eliminating the need for hazardous chemicals
2Reliability
If conventional chemical-based filtering systems are used, then bacteria, fungi, and algae control is achieved, but chemical exposure and contamination risk increase
Solution Approach 1:
The patent substitutes chemical filtration with an electrolytic filtration system that uses electrical energy to drive purification reactions. The dissimilar metal particles (copper and zinc) create galvanic cells that generate electrochemical reactions to eliminate contaminants, replacing the need for chemical additives and preventing chemical contamination of the water supply
3Object-affected harmful factors
If electrolytic filter material is used for chemical-free purification, then health safety is improved, but filter life and maintenance may be reduced
Solution Approach 1:
The patent addresses filter longevity by changing the operational parameters of the electrolytic system. By controlling the electrical current, metal particle composition, and flow rate, the system maintains effective purification while managing the consumption rate of the electrolytic material, thereby extending filter life between replacements
Solution Approach 2:
The dissimilar metal particles in the electrolytic filter continuously regenerate their purification capacity through electrochemical reactions. The system is designed to maintain the active state of the metal particles, allowing them to continuously generate antimicrobial effects without requiring external intervention or frequent replacement
