Solution Overview

Problem

In electronic cigarettes, external gas entering through the bottom causes cigarette liquid to leak from the air inlet when saturated, leading to waste and contamination, and the liquid is repeatedly heated, potentially harming users.

Innovation Solution

An atomizer design with an atomizing core featuring air intake grooves on its side wall and a recess with a partitioning isolation member, along with a liquid storage assembly and adjustment mechanism that allows controlled air intake and liquid distribution, preventing leakage and efficient use of cigarette liquid.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If air inlet is located at the bottom of the electronic cigarette and exposed to the air, then external gas can enter the electronic cigarette easily, but cigarette liquid leaks out from the air inlet when the liquid absorbing member reaches saturation

Engineering Contradiction:
Improveair intakeVSAvoidliquid leakage prevention
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The air inlet structure is segmented into multiple components: the first air inlet hole in the upper cover, the second air inlet hole in the mouthpiece connector, and the air intake groove in the atomizing core. This segmentation allows independent control and positioning of air intake paths, preventing liquid from reaching the air inlet while maintaining ease of air intake.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The atomizing core acts as an intermediary component between the liquid absorbing member and the air inlet. It includes an air intake groove that receives external gas through the intake passage and directs it to the heating element, while its structure prevents liquid from the liquid absorbing member from reaching the air inlet hole, thus solving the contradiction between easy air intake and liquid leakage prevention.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If air inlet is exposed to the air at the bottom, then gas intake is convenient, but cigarette liquid contaminates the air inlet when saturated

Engineering Contradiction:
Improvegas intakeVSAvoidliquid contamination
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The air intake function is extracted from the bottom structure and relocated to the upper cover and mouthpiece connector area. The first air inlet hole in the upper cover and the second air inlet hole in the mouthpiece connector provide gas intake pathways that are spatially separated from the liquid absorbing member, preventing liquid contamination while maintaining convenient gas intake.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The air intake pathway is moved from the vertical bottom dimension to the horizontal upper dimension. The air intake groove in the atomizing core receives gas laterally from the intake passage, and the heating element is positioned to receive gas from this groove, creating a dimensional separation that prevents liquid from contaminating the air inlet.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Productivity

If cigarette liquid is repeatedly heated, then atomization continues, but harmful substances are generated that may harm users

Engineering Contradiction:
Improveatomization continuityVSAvoidharmful substances
Core Design Contradiction:
ProductivityVSObject-generated harmful factors

Solution Approach 1:

The system dynamically controls liquid supply to the heating element through the liquid absorbing member and intake passage configuration. Air flow through the air intake groove and air intake hole creates a dynamic environment that prevents liquid accumulation on the heating element, allowing continuous atomization while reducing the generation of harmful substances from repeated heating of the same liquid.

Inventive Principle:
Principle #15Dynamics
