Solution Overview

Problem

Conventional electronic cigarettes lack mechanisms to prevent accidental disassembly of the atomization assembly, leading to unwanted e-liquid leakage and make it difficult to replace or repair individual parts due to fixed attachments.

Innovation Solution

The electronic cigarette design incorporates a spinning ring mechanism that requires simultaneous pressing and rotating to disassemble the atomization core, preventing accidental disassembly and includes a regulating ring with air inlets to control vapor flow, allowing for easier maintenance and child safety.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the atomization assembly is fixedly attached to the battery assembly, then the structure is stable and reliable, but it becomes difficult to replace or repair individual parts

Engineering Contradiction:
Improvestructural stabilityVSAvoidparts replacement difficulty
Core Design Contradiction:
ReliabilityVSEase of repair

Solution Approach 1:

The atomization assembly is divided into separable components including the atomization core, connector, and housing sections. The connector serves as a detachable interface that allows the atomization core to be separated from the battery assembly for replacement or repair while maintaining structural stability during normal use.

Inventive Principle:
Principle #1Segmentation

2Ease of manufacture

If the atomization assembly has no anti-disassembly structures, then the device is simple and easy to manufacture, but it leads to accidental disassembly by children and unwanted e-liquid leakage

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoidprevention of accidental disassembly
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The connector incorporates a dynamic locking mechanism that requires simultaneous pressing and rotating actions to disassemble. This dynamic operation prevents accidental disassembly by children while maintaining reasonable manufacturing complexity through the use of standard mechanical components.

Inventive Principle:
Principle #15Dynamics

3Ease of operation

If the atomization core is easily removable, then it is convenient for maintenance and replacement, but it may be accidentally disassembled by children leading to e-liquid leakage

Engineering Contradiction:
Improvemaintenance convenienceVSAvoide-liquid leakage risk
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The connector requires a two-step dynamic operation (pressing then rotating) for disassembly, which maintains ease of intentional maintenance while preventing accidental removal by children. The multi-step process ensures deliberate user action is required, reducing the risk of e-liquid leakage.

Inventive Principle:
Principle #15Dynamics

4Reliability

If the atomization assembly uses complex locking mechanisms to prevent disassembly, then child safety is improved, but the device complexity increases and manufacturing becomes more difficult

Engineering Contradiction:
Improvechild safetyVSAvoidstructure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The connector uses a dynamic pressing-and-rotating mechanism that provides effective child safety protection without requiring complex locking structures. The simplicity of the mechanical design maintains manufacturing ease while achieving the safety goal through intuitive user interaction.

Inventive Principle:
Principle #15Dynamics
