Solution Overview

Problem

The existing atomizer cartridges require replacement when e-liquid is exhausted, leading to waste of the atomization core component and increased consumer costs.

Innovation Solution

An atomization device with a detachable e-liquid storage assembly and atomization assembly, allowing for the e-liquid storage chamber to be in communication with the atomization chamber through a detachable connection via an e-liquid delivery channel, facilitated by a connector and plug system.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of substance

If the e-liquid storage assembly is integrated with the atomization assembly, then the structure is simple, but the atomization core component is wasted when e-liquid is exhausted

Engineering Contradiction:
Improvewaste of atomization core componentVSAvoidstructure complexity
Core Design Contradiction:
Loss of substanceVSDevice complexity

Solution Approach 1:

The atomization device is divided into two independent assemblies: the atomization assembly containing the atomization core component and the e-liquid storage assembly containing the e-liquid reservoir. These assemblies are connected through a detachable connection mechanism with a connector on the atomization assembly and a plug on the e-liquid storage assembly. This segmentation allows the atomization core component to be reused multiple times while only the e-liquid storage assembly needs to be replaced when depleted, resolving the contradiction between structural simplicity and component waste reduction.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If the e-liquid storage chamber is positioned at the side of the atomization chamber, then detachment is facilitated and interference is avoided, but the e-liquid delivery channel must extend across the atomization chamber

Engineering Contradiction:
Improveease of detachmentVSAvoide-liquid delivery channel configuration
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The e-liquid storage chamber is positioned laterally adjacent to the atomization chamber rather than above or below it, utilizing the horizontal dimension for arrangement. This lateral positioning allows the e-liquid delivery channel to extend horizontally across the atomization chamber in a straightforward manner, while also enabling easy detachment of the e-liquid storage assembly without interfering with the atomization chamber structure. This dimensional arrangement resolves the contradiction by simplifying both the detachment process and the channel configuration.

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