Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If high-voltage electric energy is used to generate plasma, then plasma generation efficiency is improved, but water temperature increases causing thermal distortion
Solution Approach 1:
The plasma generation system is divided into two independent reactors: a first reactor for plasma generation and a second reactor for bubble generation. This segmentation allows plasma to be generated without direct contact with water, preventing thermal distortion while maintaining generation efficiency.
Solution Approach 2:
Bubbles serve as an intermediary medium between the plasma generation process and water treatment. The bubbles carry plasma reactions to the water interface, enabling treatment without direct plasma-water contact that would cause heating.
2Reliability
If external bubbles are inserted into water for plasma generation, then plasma reaction is enabled, but bubble size and stability are inappropriate leading to poor reaction rates
Solution Approach 1:
The second reactor is designed to autonomously generate bubbles of appropriate size and stability directly within the water stream. This self-service bubble generation eliminates the need for external bubble insertion equipment and ensures bubbles are optimized for plasma reaction from the moment of creation.
3Productivity
If plasma reacts with organic substances in water, then water treatment occurs, but stable plasma reaction cannot be maintained
Solution Approach 1:
The system maintains continuous plasma generation through the first reactor and continuous bubble generation through the second reactor. This ensures a steady supply of plasma-carrying bubbles that continuously interact with organic substances, maintaining both treatment productivity and reaction stability.
4Productivity
If the plasma unit is designed with complex reactor structures, then treatment efficiency is improved, but connection to standard water course pipes becomes difficult
Solution Approach 1:
The plasma unit is designed with universal connection interfaces that can connect to standard water course pipes while accommodating the dual-reactor configuration. The compact integration of both reactors allows the unit to maintain high treatment efficiency while being adaptable to existing piping infrastructure.
