Solution Overview

Problem

Aerosol generating devices in prior art tend to leak tobacco juice during standing or transportation, leading to waste and surface staining, which negatively affects user experience.

Innovation Solution

An atomization assembly with a sealing mechanism comprising a shell, a sealing seat, an atomization core, and a seal, where the seal includes a sealing part and a push rod that covers the passing juice orifice to prevent leakage, and can be manually opened and closed to facilitate juice usage and storage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the atomization assembly is designed with an open juice storage cavity for easy access, then the ease of operation is improved, but tobacco juice leaks during transportation and storage, causing waste and contamination

Engineering Contradiction:
Improveaccess to juice storage cavityVSAvoidtobacco juice leakage
Core Design Contradiction:
Ease of operationVSLoss of substance

Solution Approach 1:

The patent applies preliminary action by providing a sealable passing juice orifice that can be closed before transportation or storage. The seal includes a sealing part that covers the orifice and a push rod that can be operated to seal the orifice in advance, preventing juice leakage during transit while allowing easy access when needed.

Inventive Principle:
Principle #10Preliminary action

2Loss of substance

If a sealable orifice is added to prevent juice leakage, then the loss of substance is reduced, but the device complexity increases due to additional sealing components

Engineering Contradiction:
Improvetobacco juice leakageVSAvoidsealing mechanism structure
Core Design Contradiction:
Loss of substanceVSDevice complexity

Solution Approach 1:

The patent extracts the sealing function into a separate, modular seal component that can be independently designed and manufactured. The seal includes a sealing part and a push rod that can be added to the existing atomization assembly without fundamentally redesigning the entire structure, thereby reducing the impact on overall device complexity.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The push rod is designed to be manually operable by the user, allowing the sealing action to be performed by the user themselves without requiring additional actuators or complex control mechanisms. This self-service approach simplifies the overall device by eliminating the need for automated sealing systems.

Inventive Principle:
Principle #25Self-service

3Productivity

If the passing juice orifice remains open for continuous juice flow, then the productivity is improved, but the atomization assembly becomes contaminated with leaked juice during storage

Engineering Contradiction:
Improvejuice flow rateVSAvoidsurface contamination
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent applies dynamics by making the passing juice orifice dynamically controllable - it can be open during use to ensure continuous juice flow and atomization productivity, and closed during storage or transportation to prevent leakage and contamination. The push rod enables the user to switch between these two states as needed.

Inventive Principle:
Principle #15Dynamics

AI summary

This matter generally relates to an aerosol generating device and an atomization assembly therein. The atomization assembly includes a shell, a sealing seat, an atomization core, and a seal. A first end of the atomization core is connected to the shell, and a second end of the atomization core is mounted on the sealing seat. The atomization core includes a passing juice orifice. The seal includes a sealing part in the juice storage cavity and a push rod connected to the sealing part. The sealing part is arranged surrounding a peripheral surface of the atomization core for covering the passing juice orifice, and the free end of push rod may pass through the sealing seat and is exposed outside of the sealing seat.
