Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing electronic atomization devices suffer from significant loss of aerosol due to the atomization surfaces facing downwards, causing aerial fog to make multiple turns before reaching the outlet, resulting in inefficiency and loss of large particulate aerosols.

Innovation Solution

The atomizer design features an atomization surface parallel or forming an acute angle with the longitudinal axis, accompanied by an air inlet channel orthogonal or forming an angle with the atomization surface, facilitating smoother airflow and reducing aerosol loss.

Core Design Contradiction:

Device complexityVSLoss of substance

Solution Approach 1:

The patent inverts the conventional downward-facing atomization surface orientation by making it parallel or forming an acute angle with the longitudinal axis. This inversion changes the airflow pattern from requiring multiple turns to a more direct path, significantly reducing aerosol loss at corner positions while maintaining structural simplicity.

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The patent introduces a new spatial dimension by changing the atomization surface orientation from the traditional vertical downward direction to a horizontal or angled configuration relative to the longitudinal axis. This dimensional change optimizes the airflow path and reduces aerosol loss without complicating the device structure.

Core Design Contradiction:

Adaptability or versatilityVSProductivity

Solution Approach 1:

By inverting the atomization surface orientation from downward-facing to parallel or acutely angled with the longitudinal axis, the patent achieves more efficient aerosol delivery. This inversion allows aerosol to reach the outlet channel with fewer turns, improving delivery efficiency while maintaining adaptability to conventional device architectures.

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The patent changes the orientation parameter of the atomization surface from vertical (downward-facing) to horizontal or acutely angled relative to the longitudinal axis. This parameter change optimizes aerosol flow dynamics and delivery efficiency without requiring fundamental redesign of the conventional device structure.

Core Design Contradiction:

Device complexityVSProductivity

Solution Approach 1:

The air inlet channel is positioned and oriented to preliminarily guide air flow in a direction that facilitates efficient aerosol gathering before the aerosol reaches the outlet channel. This preliminary action optimizes aerosol collection efficiency without requiring complex channel structures, as the orthogonal or angled configuration naturally directs flow toward the outlet.
