Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for improving water sterilization and dissolution of gases or liquids into water are inefficient, requiring high energy consumption, increased facility size, and the use of expensive ozone generators, while also posing environmental risks due to residual pollutants like trihalomethane and ozone decomposition products.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If chlorine or ozone gas is injected into water to improve water sterilization, then water sterilization is improved, but energy consumption increases and harmful substances are generated
Solution Approach 1:
The patent replaces the mechanical system of gas injection and pumping with a hydrodynamic cavitation system. The Venturi-structured micro-holes generate cavitation bubbles through pressure changes alone, eliminating the need for separate ozone generators and pump motors, thus reducing energy consumption while maintaining sterilization effectiveness
Solution Approach 2:
The patent changes the physical parameters of water by creating extreme pressure variations through the Venturi structure. The rapid pressure changes cause water molecules to decompose into hydroxyl radicals, achieving sterilization through chemical parameter changes rather than mechanical gas injection
2Quantity of substance
If a pump is used to increase water pressure to improve ozone dissolution, then ozone dissolution is improved, but energy consumption increases
Solution Approach 1:
The patent replaces the mechanical pump system with a passive hydrodynamic cavitation system. The Venturi micro-holes utilize the existing water flow to generate pressure changes that enhance ozone dissolution without requiring additional mechanical energy input
Solution Approach 2:
The dissolver tube structure itself generates the necessary pressure changes for ozone dissolution. The Venturi micro-holes create cavitation zones that automatically enhance gas-liquid mixing and dissolution without external energy input, making the system self-servicing
3Quantity of substance
If an ozone gas generator is used to inject ozone gas into water, then ozone dissolution is improved, but device complexity and cost increase
Solution Approach 1:
The patent extracts and eliminates the complex ozone gas generator from the system. By using the natural cavitation phenomenon in Venturi micro-holes, the system achieves enhanced ozone dissolution without the need for separate gas generation equipment, simplifying the overall device structure
Solution Approach 2:
The patent utilizes parameter changes in the water flow itself (pressure and velocity variations through Venturi micro-holes) to achieve the dissolution effect, replacing the need for complex external ozone generation equipment with a simple structural modification to the flow path
