Solution Overview

Problem

Conventional electronic cigarettes with thread-connected clearomizers and cartridges are inconvenient for assembly and disassembly, leading to instability and user experience issues.

Innovation Solution

A clearomizer design featuring a first and second main body with conductive connectors and a convex edge, where the second main body is inserted into a cartridge with a cavity, creating a stable structure that prevents e-liquid leakage and short circuits, allowing for convenient assembly and disassembly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the clearomizer is connected to the cartridge through threads, then the connection is secure, but the assembly and disassembly become inconvenient

Engineering Contradiction:

Improveconnection stabilityVSAvoidassembly and disassembly convenience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The clearomizer is divided into two main bodies: a first main body containing the atomizing assembly and a second main body containing conductive connectors. This segmentation allows the second main body to be inserted into the cartridge for secure connection while keeping the first main body accessible for user operation, thus resolving the contradiction between connection stability and operational convenience.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The second main body of the clearomizer is inserted into a cavity within the cartridge, creating a nested structure. This nesting provides stable mechanical connection and electrical contact while allowing easy insertion and removal, effectively solving the contradiction between secure connection and convenient assembly/disassembly.

Inventive Principle:

Principle #7Nested doll (Nesting)

2Productivity

If the air conduction hole is disposed centrally, then the air flow is straightforward, but the leaked e-liquid can flow into the battery causing short circuit

Engineering Contradiction:

Improveair flow efficiencyVSAvoidshort circuit risk

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The air conduction hole is deliberately positioned off-center on the second distal end, away from the central area. This asymmetric placement ensures that if e-liquid leaks from the atomizer, it will not flow directly into the battery compartment, thereby preventing short circuits while still maintaining adequate air flow for atomization.

Inventive Principle:

Principle #4Asymmetry

Solution Approach 2:

The tortuous air flow path created by the recesses and off-center air conduction hole acts as an intermediary mechanism. It redirects air flow and prevents direct communication between the atomizer cavity and battery area, using the air path structure as a barrier against e-liquid leakage to the battery.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Device complexity

If the second main body has the same diameter as the first main body, then the structure is simple, but the convex edge cannot abut against the cartridge for stable positioning

Engineering Contradiction:

Improvestructural simplicityVSAvoidpositioning stability

Core Design Contradiction:

Device complexityVSStability of the object's composition

Solution Approach 1:

The second main body has a reduced diameter compared to the first main body, creating a localized structural variation. This local change enables the convex edge on the first main body to abut against the cartridge, providing stable positioning and preventing over-insertion, while the overall structure remains relatively simple and functional.

Inventive Principle:

Principle #3Local quality
