Solution Overview

Problem

Existing atomizers for heat-not-burn aerosol-generating substrates fail to fully bake the substrate, leading to a reduced amount of effective substances in the aerosol output, which diminishes user experience.

Innovation Solution

The atomizer design includes a first and second airflow channel that bypasses the heating section, allowing airflow to enter the substrate through side inlets, maintaining stable heating temperature and ensuring complete release of effective substances.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If airflow enters from the bottom of the aerosol-generating substrate, then the substrate can be heated, but the temperature of the substrate is reduced, preventing thorough baking and complete release of effective substances

Engineering Contradiction:
Improvesubstrate temperatureVSAvoidamount of effective substances
Core Design Contradiction:
TemperatureVSQuantity of substance

Solution Approach 1:

The airflow path is segmented into multiple channels: a first airflow channel that bypasses the heating section and a second airflow channel that enters through the side wall of the substrate section. This segmentation allows the heating section to maintain stable temperature while still providing adequate airflow for effective substance release.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The first airflow channel acts as an intermediary path that allows air to bypass the heating section without cooling it, while the second airflow channel provides the necessary airflow for effective substance release. This intermediary airflow path resolves the conflict between maintaining temperature and releasing substances.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If airflow cools the substrate to allow user inhalation, then the substrate temperature decreases, but the effective substances cannot be completely released

Engineering Contradiction:
Improveuser inhalationVSAvoideffective substances released
Core Design Contradiction:
Ease of operationVSQuantity of substance

Solution Approach 1:

The airflow system is divided into two separate channels: the first airflow channel provides cooling air for user inhalation by bypassing the heating section, while the second airflow channel provides heating air that enters through the side wall to ensure complete release of effective substances. This segmentation allows both functions to operate simultaneously without interfering with each other.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different regions of the substrate are given different airflow qualities: the heating section receives hot air through the second airflow channel to maintain high temperature for complete substance release, while the user inhalation path receives cooler air through the first airflow channel for comfort. This local differentiation of airflow quality resolves the contradiction between cooling for inhalation and heating for substance release.

Inventive Principle:
Principle #3Local quality

AI summary

The present application relates to an atomizer adapted to heat and atomize an aerosol-generating substrate (300). The atomizer includes a main body (120, 210) having an accommodating cavity (160, 250), and the accommodating cavity (160, 250) has an open end and a closed end opposite to each other. A substrate section (320) and a hollow section (340) of the aerosol-generating substrate (300) are adapted to be inserted in the accommodating cavity (160, 250). A gap is to be defined between the aerosol-generating substrate (300) and the side wall of the accommodating cavity (160, 250), forming a first airflow channel (1632, 2541) that is in communication with a first air inlet (341) of the aerosol-generating substrate (300) and a second airflow channel (1634, 2543) that is in communication with the first airflow channel (1632, 2541) and a second air inlet (321) of the aerosol-generating substrate (300).
