Solution Overview

Problem

Cigarette mouthpieces made of soft materials provide better tactility but have unreliable connections, shorter service life, and are prone to discoloration and contamination compared to hard plastic counterparts.

Innovation Solution

A cigarette mouthpiece design featuring a hard substrate with a through hole for smoke passage and soft substrates mounted on the outside, with grooves and retaining structures for secure attachment, combining the benefits of both materials for improved reliability and longevity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a cigarette mouthpiece is made of soft materials, then user tactility is improved, but connection reliability deteriorates

Engineering Contradiction:

Improveuser tactilityVSAvoidconnection reliability

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The mouthpiece combines soft substrate (providing tactility) with hard substrate (providing connection reliability). The soft substrate is mounted on the hard substrate, creating a composite structure that delivers both comfort and structural integrity for reliable connection to the atomization pole.

Inventive Principle:

Principle #40Composite materials

2Ease of operation

If a cigarette mouthpiece is made of soft materials, then user tactility is improved, but service life deteriorates

Engineering Contradiction:

Improveuser tactilityVSAvoidservice life

Core Design Contradiction:

Ease of operationVSDuration of action of stationary object

Solution Approach 1:

The hard substrate provides durability and extended service life, while the soft substrate maintains user comfort. This composite approach allows the mouthpiece to withstand prolonged use without the degradation issues associated with purely soft materials.

Inventive Principle:

Principle #40Composite materials

3Ease of operation

If a cigarette mouthpiece is made of soft materials, then user tactility is improved, but resistance to contamination deteriorates

Engineering Contradiction:

Improveuser tactilityVSAvoidcontamination resistance

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The hard substrate provides a non-porous, easy-to-clean surface that resists contamination and discoloration, while the soft substrate layer maintains user comfort. The hard base layer prevents the soft material from absorbing contaminants.

Inventive Principle:

Principle #40Composite materials

AI summary

Provided is a cigarette mouthpiece, a cartomizer and an electronic cigarette therefor. The cigarette mouthpiece includes a hard substrate (10). A through hole is defined inside the hard substrate (10) and extends through its upper end and lower end. A soft substrate (20) is mounted on the outside of the hard substrate (10). When a user's lips come in contact with the cigarette mouthpiece, the user's lips can obtain soft and comfortable tactility by providing the soft substrate (20) on the hard substrate (10). At the same time, the use of the hard substrate (10) in cooperation with the soft substrate (20) ensures the reliability of the cigarette mouthpiece, reduces the risk of contamination and prolongs the service life.
