Solution Overview

Problem

Existing electronic cigarettes suffer from e-liquid leakage due to vibrations, temperature, or pressure changes, which causes e-liquid to excessively enter the airflow passage, leading to leakage and poor isolation between e-liquid and vapor.

Innovation Solution

The cartridge features an atomizing base made of an elastic material with through holes, where a liquid absorbing member, potentially made of a hard material like a porous ceramic rod, is tightly fitted within these holes, eliminating gaps and preventing e-liquid leakage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If the liquid storage chamber and airflow passage are in communication through a liquid guiding rope or gap, then e-liquid can flow to the atomizing area, but vibrations, temperature or pressure changes cause excessive e-liquid to enter the airflow passage causing leakage

Engineering Contradiction:
Improvee-liquid flow controlVSAvoide-liquid leakage prevention
Core Design Contradiction:
Quantity of substanceVSReliability

Solution Approach 1:

The atomizing base is made of elastic material that can deform under vibration, temperature, or pressure changes to maintain sealing against the liquid absorbing member, preventing e-liquid leakage while allowing controlled flow

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The elastic material's deformation characteristics change with environmental conditions (vibration, temperature, pressure), allowing the sealing interface to adapt dynamically and maintain reliable e-liquid containment under varying operating conditions

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If traditional atomizing bases are used with liquid guiding ropes, then e-liquid can reach the atomizing chamber, but gaps between components cause leakage and poor isolation between e-liquid and vapor

Engineering Contradiction:
Improvee-liquid deliveryVSAvoidisolation between e-liquid and vapor
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The liquid absorbing member is integrated directly into the atomizing base through tight fitting in through holes, eliminating separate liquid guiding ropes and gaps, thereby achieving both effective e-liquid delivery and precise isolation between e-liquid and vapor phases

Inventive Principle:
Principle #5Merging (Combining)

3Quantity of substance

If conventional atomizing bases are used, then e-liquid can flow to the electrode, but assembly complexity increases and leakage occurs at the liquid inlet hole or installation gap

Engineering Contradiction:
Improvee-liquid distributionVSAvoidassembly process
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

The atomizing base is segmented with through holes that receive the liquid absorbing member, creating modular components that are easier to assemble while maintaining reliable e-liquid distribution and preventing leakage at connection interfaces

Inventive Principle:
Principle #1Segmentation

AI summary

A cartridge includes a liquid storage chamber and an atomizing device. The atomizing device includes an atomizing base and a liquid absorbing member installed in the atomizing base. The atomizing base is provided with an atomizing chamber therein. The atomizing base is made of an elastic material. The atomizing base is provided with a through hole. The liquid absorbing member extends through the through hole, and the inner wall of the through hole closely abuts against the outer wall of the liquid absorbing member to isolate the liquid storage chamber from the atomizing chamber. No gap causing e-liquid leakage is present between the liquid absorbing member and the through hole, thereby effectively preventing e-liquid leakage, achieving good isolation between e-liquid and vapor, and simplifying the assembly process. An electronic cigarette having the cartridge is also provided. The electronic cigarette has the advantages of e-liquid leakage prevention, good isolation between e-liquid and vapor, and simple assembly.
