Solution Overview

Problem

Existing electronic cigarettes have a complicated structure due to the integral formation of e-liquid tanks and atomizers, making them costly and inconvenient for users to refill and disassemble.

Innovation Solution

A detachable atomizer and e-liquid tank design, where the atomizer and e-liquid tank are connected via independent connection pieces such as screw threads, interference fits, or snap fasteners, allowing for easy assembly and disassembly, and eliminating the need to prefill the e-liquid tank.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the e-liquid tank and atomizer are integrally formed, then the structure is compact and reliable, but the device complexity increases and manufacturing cost rises

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

Solution Approach 1:

The electronic cigarette system is divided into separate functional modules: the atomizer assembly (comprising atomizing body, heating element, and connection piece) and the e-liquid tank (comprising tank body and connection piece). These modules can be independently manufactured, assembled, and replaced, reducing overall device complexity while maintaining reliability through standardized connections.

Inventive Principle:
Principle #1Segmentation

2Stability of the object's composition

If the e-liquid tank and atomizer are integrally formed, then the connection is stable, but the ease of operation deteriorates due to inability to disassemble and refill

Engineering Contradiction:
Improveconnection stabilityVSAvoidrefilling convenience
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The connection between the atomizer and e-liquid tank transitions from a fixed integral structure to a dynamic detachable structure. The connection pieces enable the system to switch between connected (stable operation) and disconnected (refilling) states, providing both connection stability during use and operational flexibility for refilling.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

By segmenting the e-liquid tank and atomizer into separate detachable components with standardized connection pieces, the system allows users to easily disconnect and refill the e-liquid tank without affecting the atomizer, significantly improving refilling convenience while maintaining connection stability when assembled.

Inventive Principle:
Principle #1Segmentation

3Ease of manufacture

If the e-liquid tank and atomizer are integrally formed, then the manufacturing process is simplified, but the ease of manufacture deteriorates due to higher production costs

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoidproduction cost
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The system is manufactured as separate modules (atomizer assembly and e-liquid tank) that can be produced independently using optimized processes for each component. This segmentation allows for specialized manufacturing techniques, bulk production of common parts like connection pieces, and reduced tooling costs, ultimately lowering overall production costs despite the additional assembly step.

Inventive Principle:
Principle #1Segmentation
