An electronic cigarette atomizer design featuring a housing body with separate battery and cigarette cartridge bins, a detachable base with a mounting hole for the cartridge, and a magnetic connection, along with a microphone for airflow sensing, ensures secure and convenient cartridge replacement and protection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the cigarette cartridge is exposed outside the atomizer to facilitate installation and replacement, then the ease of operation is improved, but the reliability deteriorates as the cartridge may fall off

Engineering Contradiction:
Improveease of cartridge installation and replacementVSAvoidcartridge retention stability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The cigarette cartridge is nested inside the atomizer housing, specifically within a dedicated cartridge receiving cavity. This nested configuration allows the cartridge to be protected and retained while still allowing for easy insertion and removal through the openable housing structure, resolving the contradiction between exposure for ease of operation and containment for reliability.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The housing incorporates an openable structure with a hinge mechanism that allows dynamic access to the cartridge. The housing can be opened to facilitate cartridge installation and replacement, then closed to secure and protect the cartridge, providing both ease of operation and reliability through dynamic structural transformation.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If the cigarette cartridge is exposed outside the atomizer, then the ease of operation is improved, but the object-generated harmful factors worsen as the cartridge is more prone to falling

Engineering Contradiction:
Improveease of cartridge installation and replacementVSAvoidcartridge falling risk
Core Design Contradiction:
Ease of operationVSObject-generated harmful factors

Solution Approach 1:

By nesting the cartridge within the protected cavity of the atomizer housing, the design eliminates the harmful effect of cartridge falling while maintaining accessibility for installation and replacement through the openable housing structure.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The housing structure provides pre-established protective containment for the cartridge before any potential falling can occur. The cavity and hinge mechanism are designed in advance to prevent the harmful effect of cartridge dislodgement while still allowing easy user access.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

3Ease of manufacture

If the housing body is made detachable with separate bins, then the ease of manufacture is improved, but the device complexity increases

Engineering Contradiction:
Improvemanufacturing flexibility and assemblyVSAvoidstructural complexity of housing and base
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The atomizer is segmented into distinct modular components: a housing body containing separate battery and cartridge bins, and a detachable base with mounting features. This segmentation allows independent manufacturing and assembly of each module, improving ease of manufacture while the standardized connection interfaces manage the resulting structural complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The detachable base and housing design provide multi-functionality, allowing the same structural components to serve both as manufacturing modules for easy assembly and as functional elements for cartridge retention and battery accommodation, thereby managing complexity through versatile design.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

An electronic cigarette atomizer includes a housing body, a cigarette holder, and a base. A battery bin and a cigarette cartridge bin are disposed in the housing body. A battery is detachably disposed in the battery bin. A first opening communicating with the battery bin and the cigarette cartridge bin is defined at a first end of the housing body. A second opening communicating with the cigarette cartridge bin is defined at a second end of the housing body. The cigarette holder communicating with the second opening is detachably disposed at one end, close to the second opening, of the housing body. A printed circuit board (PCB) is disposed in the base. An ejector pin is connected to the PCB. A mounting hole is further defined on the base. The mounting hole is configured to detachably mount a cigarette cartridge. An air inlet hole is further defined on the base.
