Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If ultrasonic vibration is used to atomize washing waste solution, then separation efficiency of solvent from contaminated compounds is improved, but equipment cost and running cost increase
Solution Approach 1:
The patent replaces the ultrasonic vibration mechanism (mechanical system requiring ultrasonic oscillators and power amplifiers) with a gas flow-based atomization system. Carrier gas flows through nozzles to atomize the washing waste solution into mist, eliminating the need for expensive ultrasonic components while maintaining effective atomization and separation performance
Solution Approach 2:
The patent employs pneumatic principles by using carrier gas flow to atomize the liquid washing waste solution. The gas flow through nozzles creates a gas-mist mixture that facilitates separation of volatile solvent components from non-volatile contaminants, achieving efficient separation without mechanical vibration systems
2Device complexity
If spray nozzle is used to atomize washing waste solution, then equipment cost is reduced, but separation efficiency of solvent from contaminated compounds deteriorates
Solution Approach 1:
The patent introduces carrier gas as an intermediary substance that facilitates the separation process. The carrier gas flows through the nozzles and interacts with the washing waste solution, enabling efficient atomization and subsequent separation of volatile components from contaminants through the gas-mist mixture formed during carrier gas flow
Solution Approach 2:
The patent changes the operational parameters by controlling carrier gas flow rate, nozzle design, and gas-solution interaction conditions. These parameter adjustments optimize the atomization quality and separation efficiency, allowing the simple nozzle structure to achieve effective separation when properly configured with carrier gas flow
3Device complexity
If nozzle sprays whole washing waste solution into cyclone vaporizer, then equipment structure is simplified, but separation between solvent and contaminated compounds is insufficient
Solution Approach 1:
The patent segments the washing waste solution into fine mist droplets through the nozzle atomization process. This segmentation creates a large surface area for evaporation and separation, allowing the simple nozzle structure to achieve effective separation of volatile solvent components from non-volatile contaminants through enhanced mass and heat transfer
