Solution Overview

Problem

Existing aerosol generation devices face challenges in efficiently heating aerosol substrates to release aerosols while maintaining energy efficiency and preventing damage to the heating chamber.

Innovation Solution

A heating chamber design with a platform extending from the base, shaped to elongate the heat flow path and compress the aerosol substrate, combined with a heater element that extends around the chamber side wall but not around the base, to optimize heat distribution and substrate interaction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If the heater extends around the base to improve heating efficiency, then the heating speed increases, but the risk of damage to the heating chamber increases

Engineering Contradiction:

Improveheating speedVSAvoiddamage risk to heating chamber

Core Design Contradiction:

SpeedVSObject-affected harmful factors

Solution Approach 1:

The heater is extracted from extending around the base, positioning it only around the side wall. This removes the harmful thermal exposure to the base while preserving the heating function through alternative heat distribution paths.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The platform acts as an intermediary heat transfer element. It receives heat from the side wall through conduction and distributes it to the aerosol substrate, enabling base heating without direct heater contact and reducing damage risk.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Use of energy by moving object

If the platform compresses the aerosol substrate to improve heat transfer, then the heating efficiency increases, but the platform may cause damage to the substrate

Engineering Contradiction:

Improveheating efficiencyVSAvoidsubstrate damage

Core Design Contradiction:

Use of energy by moving objectVSObject-affected harmful factors

Solution Approach 1:

The platform surface is designed with locally varied properties - a softer, more compliant surface area that contacts the substrate to provide gentle compression for heat transfer, while maintaining structural integrity elsewhere to prevent damage.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The platform material or surface properties are modified to change the compression characteristics, providing sufficient pressure for thermal contact while staying below the damage threshold of the aerosol substrate through controlled parameter adjustment.

Inventive Principle:

Principle #35Parameter changes

3Stability of the object's composition

If the platform elongates the heat flow path to improve heat distribution, then the thermal equilibrium improves, but the energy consumption increases

Engineering Contradiction:

Improvethermal equilibriumVSAvoidenergy consumption

Core Design Contradiction:

Stability of the object's compositionVSUse of energy by moving object

Solution Approach 1:

The heat distribution function is segmented between the side wall heater and the platform conductor. The side wall provides the heat source while the platform segments the heat flow path to distribute heat evenly, reducing the need for excessive energy input.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Thermal conduction through the platform replaces the need for extended mechanical heating elements. The platform's thermal conductivity properties enable efficient heat distribution along the elongated path with minimal energy loss compared to active heating mechanisms.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

An aerosol generation device has a heating chamber for receiving a substrate carrier containing an aerosol substrate. The heating chamber includes an open first end, a chamber side wall, and a base at a second end of the chamber side wall opposite the open first end. The base includes a platform extending from a portion of the base towards the open first end from an interior surface of the base. The platform is formed of a series of protrusions positioned at an edge of the base.
