Solution Overview

Problem

In electronic vaporization devices, excessive bubbles in the liquid feeding channel obstruct liquid absorption, leading to dry burning of the vaporization core and affecting user experience and device lifespan.

Innovation Solution

A vaporization top base with at least two liquid feeding channels, featuring a first corner close to the central axis and a second corner away from it, arranged in a manner that enlarges the exit and enhances the liquid inlet area, accompanied by a protruding stage and air guide channel to improve airflow and bubble escape.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If air enters the liquid storage cavity through the vaporization core, then the vaporization process can proceed, but bubbles form in the liquid feeding channel due to excessive viscosity of the aerosol-generation substrate

Engineering Contradiction:

Improvevaporization efficiencyVSAvoidliquid feeding reliability

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The liquid feeding channel is divided into multiple segments with different cross-sectional areas, creating a stepped structure that facilitates bubble separation and prevents bubble accumulation, thereby maintaining reliable liquid feeding while enabling continuous vaporization

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The stepped structure acts as an intermediary mechanism between the liquid storage cavity and the vaporization core, providing a transition zone that allows bubbles to escape while maintaining liquid flow, thus resolving the contradiction between vaporization efficiency and liquid feeding reliability

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If bubbles accumulate in the liquid feeding channel, then liquid absorption of the vaporization core is blocked, but this obstructs liquid feeding and causes dry burning

Engineering Contradiction:

Improveliquid absorptionVSAvoidbubble obstruction

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The stepped structure converts the harmful effect of bubble formation into a beneficial separation mechanism, where bubbles are directed to escape through larger cross-sectional areas while liquid continues to flow through the channel, maintaining liquid absorption while eliminating bubble obstruction

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

Solution Approach 2:

The stepped structure with varying cross-sectional areas creates curved flow paths that facilitate bubble detachment and escape, preventing bubble accumulation and maintaining reliable liquid absorption without causing dry burning

Inventive Principle:

Principle #14Spheroidality (Curvature)

3Ease of manufacture

If the liquid feeding channel has a simple structure, then manufacturing is easier, but bubbles cannot escape effectively leading to obstructed liquid feeding

Engineering Contradiction:

Improvechannel structure simplicityVSAvoidbubble escape capability

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The liquid feeding channel is segmented into multiple sections with different cross-sectional areas, creating a stepped structure that is relatively simple to manufacture while effectively enabling bubble escape and maintaining reliable liquid feeding

Inventive Principle:

Principle #1Segmentation
