Solution Overview

Problem

Conventional atomizers experience heating element burn-out due to inadequate e-liquid airflow and condensation issues, leading to unstable e-liquid supply and staining of the atomizer when not in use.

Innovation Solution

An atomizer design featuring an e-liquid tank with an air vent and airflow channel that supplies external air to the e-liquid chamber, preventing e-liquid condensation and ensuring a stable airflow to the heating element, using a main body with grooves and a sealing member to facilitate air conduction while preventing e-liquid leakage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If external air is not supplied quickly enough to the e-liquid chamber, then the e-liquid flow to the heating element is insufficient, but the heating element may experience burn-out during subsequent puffs

Engineering Contradiction:
Improveair supply speedVSAvoidheating element stability
Core Design Contradiction:
SpeedVSReliability

Solution Approach 1:

The air vent is pre-configured in the e-liquid tank to automatically supply external air to the e-liquid chamber when negative pressure occurs, preventing the condition that leads to heating element burn-out before it happens. This preliminary air supply mechanism ensures the heating element remains stable during subsequent puffs.

Inventive Principle:
Principle #10Preliminary action

2Stability of the object's composition

If the atomizer is not in use, then e-liquid condenses and flows outside via the air passage, but this stains the atomizer

Engineering Contradiction:
Improvee-liquid condensationVSAvoidstaining
Core Design Contradiction:
Stability of the object's compositionVSObject-affected harmful factors

Solution Approach 1:

The design separates the air passage function from the e-liquid containment function by providing a dedicated air vent that allows air to pass through while preventing e-liquid from flowing outside through the same path. This extraction of the air supply function prevents condensation staining.

Inventive Principle:
Principle #2Taking out (Extraction)

3Reliability

If the air vent diameter is small, then air supply is sufficient to prevent burn-out, but e-liquid may leak through the air channel

Engineering Contradiction:
Improveheating element protectionVSAvoide-liquid leakage
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The air vent has specific dimensional parameters (diameter 0.01-0.3mm, groove depth 0.01-0.3mm, groove width ≤2mm) that create local quality differences - the dimensions are optimized to allow air molecules to pass through while blocking larger e-liquid molecules, thus preventing leakage while maintaining sufficient air supply.

Inventive Principle:
Principle #3Local quality
