If air passages are made large to allow sufficient air intake, then airflow is improved, but device compactness deteriorates
Solution Approach 1:
The air passage is designed with non-uniform cross-sectional area, being smaller near the reservoir and larger near the mouthpiece. This local variation in geometry allows the passage to maintain a compact overall footprint while providing sufficient airflow capacity where needed, resolving the contradiction between compactness and airflow rate.
Solution Approach 2:
The air passage utilizes three-dimensional space efficiently by varying its cross-sectional area along its length, transitioning from a narrow section near the reservoir to a wider section near the mouthpiece. This dimensional optimization allows adequate airflow without increasing the overall device volume proportionally.

If channel cross-sectional area is reduced to improve compactness, then device compactness is improved, but fluid flow capability deteriorates
Solution Approach 1:
The channel is designed with varying cross-sectional area along its length, being narrower near the reservoir and progressively wider toward the wick. This local quality variation allows the channel to maintain a compact overall size while providing sufficient flow capacity where needed, resolving the contradiction between compactness and fluid flow capability.
Solution Approach 2:
The air passage geometry is pre-configured to create favorable flow conditions for the pre-vapor formulation, using the narrowing near the reservoir to create suction effects that assist in drawing the formulation through the compact channel to the wick.
