Solution Overview

Problem

Existing aerosol generating devices face issues with atomization media hardening after aerosol generation, leading to transmission blockages and affecting user experience.

Innovation Solution

The aerosol generating substrate features at least two medium layers on a base band, arranged at intervals, which can be separated after heating to prevent hardening and ensure smooth transmission.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If atomization media are blended together before and after the aerosol generating substrate, then the aerosol smell is blended, but the transmission smoothness is affected due to hardening blockages

Engineering Contradiction:

Improveaerosol smell blendingVSAvoidtransmission smoothness

Core Design Contradiction:

Ease of manufactureVSEase of operation

Solution Approach 1:

The patent divides the medium layers into multiple separate layers arranged at intervals on the base band, rather than using a continuous layer. This segmentation allows each layer to be heated and atomized independently, preventing the hardening blockages that occur when atomization media are blended together in a continuous stream, while still achieving aerosol smell blending through the interval arrangement of multiple layers.

Inventive Principle:

Principle #1Segmentation

2Ease of manufacture

If the aerosol generating substrate is made into a band shape to solve smell blending, then transmission blockage occurs due to medium layers hardening after atomization

Engineering Contradiction:

Improveaerosol smell blendingVSAvoidtransmission continuity

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The patent applies different properties to different parts of the base band by arranging medium layers at specific intervals rather than continuously. The local intervals between medium layers allow for aerosol smell blending while preventing the continuous hardening that causes transmission blockages, thus maintaining transmission continuity through localized quality differentiation.

Inventive Principle:

Principle #3Local quality

3Area of stationary object

If medium layers are arranged continuously to ensure complete coverage, then transmission blockage occurs due to hardening, but if arranged at intervals, coverage is reduced

Engineering Contradiction:

Improvemedium layer coverageVSAvoidtransmission continuity

Core Design Contradiction:

Area of stationary objectVSReliability

Solution Approach 1:

The patent segments the medium layers and arranges them at intervals on the base band rather than continuously. This segmentation reduces the total coverage area compared to continuous arrangement, but eliminates the transmission blockages caused by continuous hardening of atomization media, thereby ensuring transmission continuity through strategic interval placement.

Inventive Principle:

Principle #1Segmentation
