Solution Overview

Problem

Existing electronic smoking devices struggle to consistently produce aerosol with optimal particle size for enhanced throat hit, smoothness, and flavor, as the distance between the air inlet and atomizing element is fixed, limiting control over aerosol attributes.

Innovation Solution

The atomizing chamber is designed to be adaptable in terms of the distance between the air inlet opening and the atomizing element, allowing for adjustable airflow velocity by moving the base member relative to the tubular body, which influences aerosol particle size and attributes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the distance between the air inlet opening and the atomizing element is fixed, then the device structure is simple, but the aerosol attributes (particle size, throat hit, smoothness, flavor) cannot be optimized

Engineering Contradiction:
Improveaerosol attribute customizationVSAvoidatomizing chamber structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The atomizing chamber is designed with a movable base member that can be adjusted relative to the tubular body, transforming the fixed distance into an adjustable one. This dynamic structure allows users to change the distance between the air inlet opening and the atomizing element, thereby customizing aerosol attributes such as particle size, throat hit, smoothness, and flavor.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The atomizing chamber is divided into separable components: a tubular body and a base member that can move relative to each other. This segmentation enables independent adjustment of the base member position, allowing customization of the air inlet distance without affecting other components, thus achieving aerosol attribute optimization while maintaining structural simplicity.

Inventive Principle:
Principle #1Segmentation

2Speed

If the distance between the air inlet opening and the atomizing element is increased, then the air velocity over the atomizing element decreases, but the aerosol particle size becomes larger which may reduce throat hit

Engineering Contradiction:
Improveair velocityVSAvoidaerosol particle size
Core Design Contradiction:
SpeedVSQuantity of substance

Solution Approach 1:

The adjustable base member allows users to dynamically change the distance between the air inlet opening and the atomizing element. By moving the base member closer to or farther from the tubular body, users can control the air velocity over the atomizing element, thereby optimizing the balance between throat hit (requiring higher velocity) and aerosol particle size (affected by velocity).
