Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional electrolyzed water is used for cleaning, then cleaning function is provided, but storage stability is low due to volatile chlorine gas
Solution Approach 1:
The patent applies phase transition by converting chlorine gas into chlorine nanobubbles (gas-liquid phase transition). The nanobubble generator transforms volatile chlorine gas into fine bubbles with diameter of 100 nm or less, which remain suspended in the electrolyzed water solution. This phase transition prevents chlorine gas from volatilizing into the air while maintaining its cleaning and disinfecting functions in the liquid phase.
2Productivity
If conventional electrolyzed water is used for cleaning, then cleaning function is provided, but cleaning efficiency is insufficient
Solution Approach 1:
The patent applies parameter changes by modifying the physical state of chlorine from gas to nanobubbles, which fundamentally changes its interaction with surfaces. The nanobubble form increases surface area contact, enhances penetration into pores and crevices, and maintains stable suspension in the solution. This parameter change from gas phase to nanobubble phase directly improves cleaning efficiency while maintaining reliability.
