Solution Overview

Problem

Existing electronic cigarettes lack the ability to adjust aerosol output, leading to user dissatisfaction.

Innovation Solution

A mouthpiece assembly with a rotating blocking element that adjusts the area of an opening between a through hole and air inlet, allowing for adjustable air output, comprising a mouthpiece with a sucking end, connecting end, and air passage, and a base with a blocking element that can rotate relative to the base to change the air flow area.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a fixed air inlet structure is used in electronic cigarettes, then the device structure is simple, but the aerosol output cannot be adjusted

Engineering Contradiction:

Improveaerosol output adjustabilityVSAvoidmouthpiece assembly structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The blocking element is designed to rotate relative to the base, changing the opening area dynamically. The mouthpiece can drive the blocking element to rotate, making the air flow path adjustable from fixed to variable, thereby enabling aerosol output adjustment without complex control systems

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The blocking element serves multiple functions: it blocks air flow when rotated to certain positions, allows air flow when rotated to other positions, and can be driven by the mouthpiece for adjustment. This single component provides both structural support and flow control functionality

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Ease of operation

If the air inlet area is fixed, then the manufacturing is simple, but the user satisfaction is reduced due to inability to adjust aerosol output

Engineering Contradiction:

Improveuser control over aerosol outputVSAvoidmouthpiece assembly fabrication

Core Design Contradiction:

Ease of operationVSEase of manufacture

Solution Approach 1:

The design transforms a static air inlet into a dynamic adjustable opening. The rotating blocking element allows users to control aerosol output by changing the opening area, providing ease of operation while maintaining relatively simple manufacturing processes

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The air inlet is segmented into multiple possible opening areas through the through holes in the blocking element. By rotating the blocking element to different positions, different segments of the air inlet are activated, enabling stepless or stepped adjustment of aerosol output

Inventive Principle:

Principle #1Segmentation

AI summary

The present disclosure relates to a mouthpiece assembly for an electronic cigarette. The mouthpiece assembly includes a mouthpiece, and a base defining an air inlet. The mouthpiece includes a sucking end, a connecting end, and an air passage. The sucking end defines an air outlet, and the air outlet is in communication with the air passage. The air inlet is in communication with the air passage. The mouthpiece assembly further includes a blocking element on the base. The blocking element is capable of preventing air from flowing through. The blocking element defines at least one through hole. The mouthpiece is capable of driving the blocking element to rotate relative to the base, so that an area of at least one opening formed by the at least one through hole and the air inlet can be changed.
