Solution Overview

Problem

Existing electronic cigarettes have a complex and costly design where the vaporizer and casing tube are integral, making replacement difficult and increasing manufacturing costs, which negatively impacts user experience.

Innovation Solution

The electronic cigarette features a vaporizer and casing tube as separate parts with a simplified screw-thread connection structure, allowing for easy disassembly and replacement, reducing manufacturing and usage costs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the vaporizer and casing tube are designed as an integral one-piece construction, then the structural strength and reliability are improved, but the device complexity and manufacturing costs increase, and the ease of repair deteriorates

Engineering Contradiction:
Improvestructural strengthVSAvoidconstruction complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent divides the vaporizer system into separate modular components: the vaporizer body and the casing tube are designed as detachable parts connected through a connection structure. This segmentation allows independent replacement of the vaporizer when cigarette liquid is exhausted, reducing manufacturing costs and improving ease of repair while maintaining reliable connection through the designed interface.

Inventive Principle:
Principle #1Segmentation

2Reliability

If the vaporizer and casing tube are designed as an integral one-piece construction, then the structural strength and reliability are improved, but the ease of manufacture and ease of repair worsen

Engineering Contradiction:
Improvestructural strengthVSAvoidmanufacturing cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The vaporizer is segmented into replaceable modules (vaporizer body with atomizer and casing tube), allowing the vaporizer to be manufactured separately and replaced independently. This reduces manufacturing costs by enabling standardized production of modular components and facilitates easier repair through simple replacement rather than complex assembly.

Inventive Principle:
Principle #1Segmentation

3Strength

If a twist-lock connection structure or snap-fit connection structure is used to connect the vaporizer and battery stick, then the connection strength is improved, but the device complexity increases and the ease of operation deteriorates

Engineering Contradiction:
Improveconnection strengthVSAvoiddisassembly convenience
Core Design Contradiction:
StrengthVSEase of operation

Solution Approach 1:

The connection structure is segmented into a battery stick connection portion and a vaporizer connection portion with a threaded connection mechanism. This design provides sufficient connection strength through threading while maintaining ease of operation, as the threaded connection allows for simple screwing and unscrewing actions that are more convenient than twist-lock or snap-fit mechanisms.

Inventive Principle:
Principle #1Segmentation

AI summary

Disclosed is an electronic cigarette, comprising a battery stick (10), an atomizer component, and a mouthpiece (40) that are interconnected. The electronic cigarette is characterized in that the battery stick (10) comprises a battery, a battery stick housing (101) sleeving the battery, and a first interconnection piece (1) provided at the end of the battery stick housing (101) close to the atomizer component. The atomizer component comprises an atomizer (20) and an atomizer housing (30) of the atomizer (20) sleeved in the inner cavity. The atomizer (20) comprises an atomizer tube body (201) and a second interconnection piece (2) provided at the end of the atomizer tube body (201) close to the battery stick (10). A third interconnection piece (3) is provided at the end of the atomizer housing (30) close to the battery stick (10). The second interconnection piece (2) is connected to the first interconnection piece (1), by being in contact with each other, and the third interconnection piece (3) is detachably connected to the first interconnection piece (1) by means of a screw thread. Such an electronic cigarette has the beneficial effects of reduction in the cost of manufacturing and using the atomizer (20) and convenient removal and replacement of the atomizer (20).
