Solution Overview

Problem

Conventional electronic cigarette atomizing cores have a low liquid guiding speed, resulting in insufficient atomizing liquid being conveyed to the heating element, leading to high temperatures and a degraded user experience due to insufficient smoke generation.

Innovation Solution

The atomizing core design includes a liquid guiding element with superimposed first, second, and third liquid guiding units, featuring micropores and liquid storage chambers, which enhance liquid guiding speed and storage capacity, and a heating element that heats the atomizing liquid to generate aerosol for inhalation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If a conventional liquid guiding element is used, then the structure is simple, but the liquid guiding speed is low and liquid storage capacity is insufficient

Engineering Contradiction:

Improveliquid guiding speedVSAvoidliquid guiding element structure

Core Design Contradiction:

SpeedVSDevice complexity

Solution Approach 1:

The liquid guiding element is divided into multiple liquid guiding units (first, second, and third units) with different functions. Each unit contains specific structures such as liquid storage chambers, capillary channels, and micropores, allowing the system to achieve high liquid guiding speed and sufficient storage capacity while maintaining reasonable structural complexity through functional segmentation.

Inventive Principle:

Principle #1Segmentation

2Temperature

If the heating element constantly works, then aerosol generation is maintained, but insufficient atomizing liquid is conveyed leading to high temperature and burning

Engineering Contradiction:

Improveheating element temperature controlVSAvoidaerosol generation

Core Design Contradiction:

TemperatureVSProductivity

Solution Approach 1:

The liquid storage chambers are pre-filled with atomizing liquid before the heating element operates. The capillary channels and micropores are designed to automatically supply liquid to the heating element before and during heating, ensuring that sufficient liquid is always available to absorb heat and prevent burning while maintaining continuous aerosol generation.

Inventive Principle:

Principle #10Preliminary action

3Quantity of substance

If the liquid storage capacity is increased, then sufficient liquid is available for heating, but the device volume increases

Engineering Contradiction:

Improveatomizing liquid storage capacityVSAvoidatomizing core volume

Core Design Contradiction:

Quantity of substanceVSVolume of moving object

Solution Approach 1:

The liquid storage chambers are nested within the liquid guiding units, which are themselves integrated into the atomizing core structure. The capillary channels and micropores are embedded within the walls of these chambers, creating a compact nested arrangement that maximizes liquid storage capacity while minimizing the overall volume of the atomizing core.

Inventive Principle:

Principle #7Nested doll (Nesting)

4Speed

If the liquid guiding speed is increased, then sufficient liquid reaches the heating element, but the liquid may evaporate prematurely in the storage chambers

Engineering Contradiction:

Improveliquid guiding speedVSAvoidatomizing liquid evaporation

Core Design Contradiction:

SpeedVSLoss of substance

Solution Approach 1:

Different regions of the liquid guiding element have different structural properties optimized for their specific functions. The liquid storage chambers have larger volume for storage, the capillary channels have intermediate dimensions for controlled transport, and the micropores have small dimensions for precise delivery to the heating element. This gradient structure enables fast liquid guiding speed while minimizing premature evaporation by limiting the surface area exposed at each stage.
