Solution Overview

Problem

Conventional electronic cigarettes have the flavored liquid in direct contact with the atomizing core even when not in use, which adversely affects the atomizing core's properties.

Innovation Solution

An electronic cigarette design featuring an atomizer assembly with silicon plugs that seal the flavored liquid from the atomizing core, using breakable necks to allow liquid contact only during use, and a sealing system that includes upper and lower sealing rings and a sealing plug to prevent leakage and protect the core.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the flavored liquid is kept in direct contact with the atomizing core for convenient operation, then the ease of operation is improved, but the reliability of the atomizing core deteriorates due to adverse effects from liquid exposure

Engineering Contradiction:

Improveconvenience of liquid contactVSAvoidatomizing core properties

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent divides the atomizer assembly into separate sealed compartments using waterproof seals and barriers. The flavored liquid is contained in a reservoir section that is physically separated from the atomizing core section, allowing independent protection of the core while maintaining liquid availability for operation.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces intermediary components such as waterproof seals, barriers, and controlled delivery mechanisms between the flavored liquid and the atomizing core. These intermediaries prevent direct harmful contact while still enabling the core to access liquid vapor when needed for normal operation.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of manufacture

If the atomizer assembly is designed with simple open structure for ease of manufacture, then the ease of manufacture is improved, but the loss of substance increases due to liquid leakage

Engineering Contradiction:

Improvestructural simplicityVSAvoidflavored liquid leakage

Core Design Contradiction:

Ease of manufactureVSLoss of substance

Solution Approach 1:

The patent employs flexible waterproof seals, membranes, and thin film barriers within the atomizer assembly. These flexible sealing elements prevent liquid leakage while maintaining a relatively simple overall structure that does not require complex rigid sealing mechanisms, thus balancing manufacturability with substance retention.

Inventive Principle:

Principle #30Flexible shells and thin films

3Reliability

If the atomizer assembly uses multiple sealing components for better sealing performance, then the reliability is improved, but the device complexity increases

Engineering Contradiction:

Improvesealing performanceVSAvoidnumber of sealing components

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines multiple sealing functions into integrated sealing components and assemblies. Rather than using separate discrete seals for each interface, the design merges sealing, barrier, and structural functions into unified elements that achieve reliable liquid containment while reducing the overall number of separate components and simplifying assembly.

Inventive Principle:

Principle #5Merging (Combining)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The flavored liquid is effectively sealed from the atomizing core when not in use, protecting it and preventing damage, while allowing contact during operation to ensure proper vaporization.

Implementation Method 1

the two silicon plugs are disposed in the two through holes of the shell and seal the two blind holes of the base, respectively; the upper sealing ring is disposed between the upper cover and the shell, and the lower sealing ring is disposed between the shell and the limit cover of the heating wire; the sealing plug is disposed on the upper cover; the sealing plug is adapted to seal the flavored liquid in the shell

Methodology Applied

Scientific EffectSealing: Physical Containment

Implementation Method 2

An electronic cigarette (e-cigarette) is a handheld electronic device that uses an atomizer to vaporize a flavored liquid

Methodology Applied

Scientific EffectVaporization: Evaporation

Implementation Method 3

a heating wire comprising a limit cover and a support base; the heating wire is vertically disposed on the support base

Methodology Applied

Scientific EffectHeating: Heating

AI summary

An electronic cigarette, including an atomizer assembly, including: an upper cover; a shell having two through holes; a base having two blind holes; a heating wire having a limit cover and a support base; two silicon plugs; an upper sealing ring; a lower sealing ring; and a sealing plug. The shell is disposed between the upper cover and the base. Flavored liquid is filled in the shell, and the two silicon plugs are disposed in the two through holes of the shell and seal the two blind holes of the base, respectively. The two silicon plugs each include a breakable neck adapted to be manually broken so that the flavored liquid comes into contact with the heating wire. The upper sealing ring is disposed between the upper cover and the shell, and the lower sealing ring is disposed between the shell and the limit cover of the heating wire.
