Solution Overview

Problem

Existing electronic cigarettes suffer from poor air and aerosol mixing, noise generation due to airflow, and potential liquid overflow issues, which negatively impact user experience.

Innovation Solution

The electronic cigarette vaporization component incorporates an air inlet splitter plate with splitter holes that evenly disperse and buffer airflow, reducing noise and improving mixing, while also preventing liquid leakage through a sealed connection with the lower cover.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If air inlet channel is provided without splitter plate, then air intake is simple and device structure is simple, but air and aerosol mixing is poor and liquid leakage occurs

Engineering Contradiction:

Improveair intakeVSAvoidair and aerosol mixing quality

Core Design Contradiction:

Quantity of substanceVSManufacturing precision

Solution Approach 1:

The air inlet channel is divided into multiple air inlet channels through the air inlet splitter plate, which segments the airflow into multiple paths. This segmentation improves air and aerosol mixing quality while maintaining simple device structure, as the splitter plate naturally divides the single air inlet into multiple smaller channels without requiring complex additional components.

Inventive Principle:

Principle #1Segmentation

2Productivity

If air flows rapidly through air inlet channel, then air intake efficiency is high, but noise is generated and liquid leakage occurs

Engineering Contradiction:

Improveair intake efficiencyVSAvoidnoise and liquid leakage

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The air inlet splitter plate divides the single high-velocity air inlet into multiple smaller air inlet channels. This segmentation reduces the flow velocity in each individual channel, thereby reducing noise generation and preventing liquid leakage while maintaining overall air intake efficiency through the combined effect of multiple channels.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The splitter plate creates different local flow conditions within the air inlet system. By distributing airflow into multiple channels with different local characteristics, the system achieves reduced noise and prevented liquid leakage in each local channel while maintaining high overall air intake efficiency through the cumulative effect of all channels.

Inventive Principle:

Principle #3Local quality

3Device complexity

If air inlet channel is open without sealing, then device structure is simple, but liquid matrix and condensate overflow from air inlet

Engineering Contradiction:

Improveair inlet structureVSAvoidliquid leakage prevention

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The air inlet splitter plate segments the air inlet channel into multiple smaller channels, which naturally reduces the risk of liquid overflow in each channel. This segmentation approach prevents liquid leakage while maintaining relatively simple device structure, as the splitter plate serves both flow distribution and leakage prevention functions simultaneously.

Inventive Principle:

Principle #1Segmentation
