Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Electronic cigarettes face issues with e-liquid leakage and dust exposure due to temperature changes, part damage, or improper positioning, making it unpredictable and difficult to prevent these problems.

Innovation Solution

An electronic cigarette assembly with a housing that includes a receiving cavity, a top cover, an opener unit with a gear and elongated bar mechanism, and an atomizer control unit, allowing the device to be easily switched between closed and open positions to prevent dust and leakage, with the atomizer turning on and off accordingly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If the electronic cigarette is kept closed to prevent dust and leakage, then protection against dust and leakage is improved, but accessibility and ease of operation deteriorate

Engineering Contradiction:

Improvedust and leakage protectionVSAvoidaccessibility

Core Design Contradiction:

Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The electronic cigarette employs a dynamic sliding mechanism where the cartridge can move between a inserted position (protected) and a pulled-out position (accessible). This dynamic structure allows the device to transition between closed and open states, providing dust and leakage protection when inserted while maintaining ease of operation when pulled out for use.

Inventive Principle:

Principle #15Dynamics

2Ease of operation

If the electronic cigarette is made accessible and easy to operate, then ease of operation is improved, but protection against dust and leakage deteriorates

Engineering Contradiction:

ImproveaccessibilityVSAvoiddust and leakage protection

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The sliding mechanism allows users to easily pull the cartridge out for operation while automatically providing protection when inserted. The dynamic design ensures that during normal use the cartridge is accessible, but when not in use it can be retracted to provide automatic protection against dust and leakage without requiring additional user actions.

Inventive Principle:

Principle #15Dynamics

3Reliability

If the housing is completely closed to prevent leakage, then reliability is improved, but ease of operation deteriorates

Engineering Contradiction:

Improveleakage preventionVSAvoidaccessibility

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The housing design incorporates a sliding cartridge mechanism that maintains complete closure and sealing when the cartridge is inserted, ensuring reliable leakage prevention. When operation is needed, the cartridge can be smoothly pulled out along the sliding track, providing easy access without compromising the sealed protection during storage or transport.

Inventive Principle:

Principle #15Dynamics
