Solution Overview

Problem

Existing atomizers in electronic cigarettes suffer from issues such as burnt flavor generation, metal pollution, and reduced atomization efficiency due to heating wire exposure and embedding, leading to smaller aerosol particles and decreased throat hit.

Innovation Solution

A cartridge design featuring a heating element embedded in a micro-porous body with through holes, where the heating element is partially embedded and positioned to promote aerosol oscillation and fusion, utilizing micro-porous bodies with different heat conductive rates and porosities to enhance aerosol particle size and quantity.

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If the heating wire is embedded in the micro-porous body, then dry burn and metal pollution are eliminated, but the heat is absorbed and conducted more rapidly causing reduced atomizing efficiency and aerosol amount

Engineering Contradiction:

Core Design Contradiction:
Object-affected harmful factorsVSProductivity

Solution Approach 1:

The patent applies local quality by creating distinct regions within the micro-porous body: a first micro-porous body with higher heat conductive rate for rapid heat dissipation away from the heating element, and a second micro-porous body with lower heat conductive rate for maintaining atomization temperature. This spatial differentiation of thermal properties resolves the contradiction between preventing dry burn and maintaining atomizing efficiency.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The micro-porous body is segmented into two functional parts: a first micro-porous body for heat conduction and a second micro-porous body for atomization. This segmentation allows each part to perform its specific function optimally, preventing the heating element from direct contact with external environment while maintaining proper temperature for vaporization.

Inventive Principle:
Principle #1Segmentation

2Reliability

If the heating wire is embedded deeper in the micro-porous body, then dry burn is prevented, but the amount of tobacco liquid contacting the heating wire decreases reducing atomizing efficiency

Engineering Contradiction:
Improveprevention of dry burnVSAvoidatomizing efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The first micro-porous body acts as an intermediary between the heating element and the external environment. It conducts heat away from the heating element rapidly, preventing dry burn, while the second micro-porous body with lower heat conduction maintains the necessary temperature for efficient atomization. This intermediary structure allows the heating element to be embedded without direct harmful effects.

Inventive Principle:
Principle #24Intermediary (Mediator)
