Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If compressed air is used to atomize aerosol generating material, then the device can generate aerosols without combustion and offer various flavors, but the internal structure becomes more complex
Solution Approach 1:
The nozzle is designed to perform multiple functions: it delivers compressed air, atomizes the aerosol generating material, and controls the airflow pattern. This multi-functionality reduces the need for separate components and simplifies the overall device structure while enabling diverse flavor delivery through the same mechanism
2Productivity
If compressed air is discharged at high speed to atomize material, then aerosol generation efficiency improves, but energy consumption increases
Solution Approach 1:
The system uses compressed air (pneumatics) to atomize the aerosol generating material, replacing thermal combustion methods. The compressed air is delivered through a nozzle designed to optimize flow patterns, achieving efficient atomization while controlling energy consumption through pneumatic rather than thermal processes
3Manufacturing precision
If the nozzle outlet diameter is reduced to increase compressed air speed, then atomization quality improves, but the amount of compressed air delivered decreases
Solution Approach 1:
The nozzle is designed with a gradient structure where the outlet diameter is smaller than the inlet diameter, creating a dynamic flow pattern. This geometry allows the compressed air to accelerate as it passes through the narrowing passage, improving atomization quality while maintaining sufficient airflow quantity through the optimized gradient design

Function Achieved in This Case
The device effectively atomizes aerosol materials into aerosols, enabling users to inhale diverse flavors and simplifying the internal structure through negative pressure operations, addressing the need for non-combustion aerosol generation.
Implementation Method 1
Air may be compressed to form compressed air
Implementation Method 2
When an aerosol generating material collides with an object with kinetic energy, the aerosol generating material may be atomized into an aerosol. A certain object may include, for example, air that is discharged at a high speed.
