Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If existing nozzle designs are used, then liquid delivery function is achieved, but mist production efficiency is poor and liquid consumption is excessive
Solution Approach 1:
The liquid inlet channel is positioned inside the pressurized air inlet channel, creating a nested tube configuration where the inner tube carries liquid and the outer tube carries pressurized air. This nested structure allows the pressurized air to directly interact with the liquid at the exit, efficiently atomizing it into mist while minimizing liquid consumption.
Solution Approach 2:
The invention utilizes pressurized air flow through the outer channel to create suction and draw liquid from the inner channel, then atomizes the liquid into fine mist droplets. This pneumatic-hydraulic interaction enables efficient mist production with minimal liquid usage.
2Productivity
If complex nozzle structures are used, then mist production capability is improved, but manufacturing cost increases
Solution Approach 1:
The nested tube structure consists of a simple inner tube for liquid and an outer tube for air, both with straightforward cylindrical geometries. This nested configuration achieves efficient mist production through its simple, robust structure that is easy and cost-effective to manufacture.
3Ease of manufacture
If simple nozzle structure is used, then manufacturing cost is reduced, but mist production efficiency decreases
Solution Approach 1:
The nested tube design with liquid inlet channel inside pressurized air inlet channel creates an optimal flow interaction pattern where pressurized air draws liquid outward and atomizes it efficiently. This simple nested structure achieves high mist production efficiency without complex internal passages or components.
Solution Approach 2:
The pneumatic-hydraulic interaction in the nested structure allows pressurized air to efficiently atomize liquid, achieving high mist production capability with a simple structure that is easy to manufacture.

Implementation Method 1
The inlet channel AIN for pressurized air has an exit mouth AINM for letting pressurized air out from the pressurized air inlet channel AIN. The exit mouth LINM for letting liquid out from the liquid inlet channel LIN and the exit mouth AINM for letting pressurized air out from the pressurized air inlet channel AIN together form the exit mouth of the nozzle N at the output end OE of the nozzle N.
