Solution Overview

Problem

Existing electronic cigarettes face issues with e-liquid blockage and inefficient heating due to condensed e-liquid in the conveying pipe, which affects vapor flow and overall performance.

Innovation Solution

The electronic cigarette design includes a cylindrical structure with a gear or knurling groove on the atomizer head to release bubbles, and a heating tube connected to the ceramic core, which heats the e-liquid to a free state, preventing blockages and ensuring efficient vapor flow.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If e-liquid is heated in the atomization assembly, then vapor flow is improved, but condensed e-liquid causes blockage in the conveying pipe

Engineering Contradiction:
Improvevapor flowVSAvoidconveying pipe blockage
Core Design Contradiction:
SpeedVSReliability

Solution Approach 1:

The atomization assembly is divided into separate functional components: the atomizer head with heating element, the conveying pipe, and the mouthpiece. This segmentation allows the heating function to be isolated in the atomizer head while the conveying pipe remains separate, preventing condensed e-liquid from blocking the entire system. The bubbles released through gear grooves further segment the e-liquid flow path.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The heating tube changes the temperature parameter of the e-liquid, heating it to a free state and preventing condensation that would cause blockages. The pneumatic switch responds to temperature-induced pressure changes in the vapor flow, automatically controlling the heating process to maintain optimal vapor generation while preventing condensation.

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If the atomizer head is designed with gear grooves or knurling grooves, then bubble release is improved, but manufacturing complexity increases

Engineering Contradiction:
Improvebubble releaseVSAvoidatomizer head manufacturing
Core Design Contradiction:
Ease of operationVSEase of manufacture

Solution Approach 1:

The atomizer head incorporates gear grooves or knurling grooves that create a porous-like structure for bubble release. These grooves allow e-liquid to pass through and form bubbles efficiently, improving vapor generation while maintaining a relatively simple manufacturing process through conventional machining or molding techniques.

Inventive Principle:
Principle #31Porous materials

3Weight of moving object

If the electronic cigarette is designed with a cylindrical structure, then portability is improved, but internal space for components is reduced

Engineering Contradiction:
ImproveportabilityVSAvoidinternal space
Core Design Contradiction:
Weight of moving objectVSVolume of stationary object

Solution Approach 1:

The electronic cigarette employs a nested arrangement where the atomization assembly is directly connected to and integrated with the battery assembly. The conveying pipe is positioned concentrically within the cylindrical housing, and components are stacked axially to maximize space utilization. This nesting allows efficient use of the limited internal volume while maintaining a compact cylindrical external form for portability.
