Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If a conventional atomizer is used, then the device structure is simple, but the liquid distribution is uneven and produces large droplets

Engineering Contradiction:
Improveliquid distribution uniformityVSAvoidatomizer structure complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The atomizer cup is divided into multiple circumferential sections with different liquid layer depth configurations. Each section has a different depth from the liquid supply surface to the atomizing surface, creating segmented zones that produce different droplet sizes. This segmentation achieves uniform liquid distribution and mixed droplet sizes without complex additional components.

Inventive Principle:
Principle #1Segmentation

2Reliability

If the liquid layer depth is increased, then the atomizing effect is enhanced, but the weight of the liquid column increases causing liquid leakage

Engineering Contradiction:
Improveatomizing performanceVSAvoidliquid column weight
Core Design Contradiction:
ReliabilityVSWeight of moving object

Solution Approach 1:

Different regions of the atomizer cup have different liquid layer depths optimized for their specific functions. The first circumferential section has a greater depth for stable atomization, while the second section has a lesser depth to prevent excessive weight. This local quality variation ensures each region performs its function optimally without causing liquid leakage.

Inventive Principle:
Principle #3Local quality

3Productivity

If the atomizer operates continuously, then productivity is maintained, but e-liquid residue accumulates causing clogging

Engineering Contradiction:
Improvecontinuous operation capabilityVSAvoidatomization consistency
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The atomizer cup rotates during operation, dynamically changing which circumferential section is at the atomization position. This rotation prevents residue accumulation in any single section, as each section periodically comes into contact with the heating element. The dynamic operation maintains continuous productivity while preventing clogging through periodic clearing of residue.

Inventive Principle:
Principle #15Dynamics

AI summary

The present application provides an atomizer and an electronic cigarette, where the atomizer includes an outer housing, and the outer housing is internally provided with a liquid storage cavity and an atomization assembly; the atomization assembly includes a first side wall and a second side wall opposite to each other, and an atomization surface extending from the first side wall to the second side wall; a holder is provided within the outer housing, and the holder is provided with a first surface opposite to the atomization surface along the axial direction of the outer housing; and an atomization cavity is formed between the first surface and the atomization surface; and the first surface is configured to be inclined towards the atomization surface along the extension direction of the atomization surface, and is configured to receive a liquid substrate seeped from the atomization assembly and/or condensate formed by condensation of the aerosol within the atomization cavity. With the use of the above atomizer, the inclined first surface on the holder is used for receiving the seeped liquid substrate and condensate, and guiding an airflow within the atomization cavity, which reduces liquid seepage, and guides and improves output of the aerosol.
