Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electrodes are placed in water to generate plasma through high voltage discharge, then plasma can be generated to ionize water, but the production efficiency is low and maintenance costs are high due to difficulty in stably maintaining gas in water
Solution Approach 1:
The invention extracts and eliminates the electrode component from the plasma generation system. Instead of using electrodes to generate plasma in water, the patent uses a nozzle to generate plasma in air and then allows the plasma to contact the water surface, thereby solving the problems of electrode corrosion, gas dissolution difficulty, and low production efficiency.
Solution Approach 2:
The invention introduces air as an intermediary medium. Plasma is generated in air through the nozzle and then this plasma contacts the water surface to transfer active species. This intermediary approach avoids the direct electrode-water contact problems while maintaining effective plasma activation of water.
2Ease of manufacture
If plasma is generated on the surface of water rather than in water, then the setup is simpler, but very small amounts of ionized activated water are produced because current flows along the surface
Solution Approach 1:
The invention changes the plasma generation from a two-dimensional surface phenomenon to a three-dimensional volumetric process. By generating plasma in air through a nozzle and allowing it to contact the water surface, the plasma can penetrate and ionize water more effectively, increasing the quantity of activated water produced while maintaining setup simplicity.
3Reliability
If high voltage is used to generate plasma in water through electrodes, then plasma activation can be achieved, but high costs are incurred for production facility setup and maintenance
Solution Approach 1:
The invention replaces expensive, durable electrodes with a simpler, potentially disposable or easily replaceable nozzle system. The nozzle generates plasma through aerodynamic processes rather than electrical discharge, eliminating the need for costly electrode materials and their associated maintenance infrastructure.
Solution Approach 2:
The invention substitutes the electrical discharge mechanism (electrodes with high voltage) with a mechanical/aerodynamic mechanism (nozzle generating plasma through gas flow). This substitution reduces dependency on complex electrical infrastructure and high-voltage equipment, thereby reducing facility setup and maintenance costs.
