Solution Overview

Problem

In electronic smoking devices, users face issues when trying to replace the liquid, as new liquid mixes with the previous liquid in the atomizer, affecting the user's experience.

Innovation Solution

An atomizer with a fixing section for removability within the electronic smoking device, featuring a lateral opening and a fixing element for easy installation and removal, allowing for separate liquid reservoirs and preventing mixing of liquids.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the atomizer is made removable with a lateral opening for easy replacement, then the ease of operation is improved, but the device complexity increases due to additional fixing elements and lateral opening structure

Engineering Contradiction:
Improveease of atomizer replacementVSAvoiddevice complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The atomizer is divided into a removable cartridge section containing the liquid reservoir and a fixed base section with the heating element. This segmentation allows the cartridge to be easily removed and replaced through the lateral opening without affecting the base structure, resolving the contradiction between ease of replacement and device complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The liquid reservoir is extracted as a separate removable cartridge that can be independently replaced. The lateral opening provides direct access to insert and remove the cartridge without disassembling other parts of the device, improving ease of operation while maintaining simple overall structure.

Inventive Principle:
Principle #2Taking out (Extraction)

2Ease of manufacture

If the atomizer is designed with a lateral opening for receiving the atomizer, then the ease of manufacture is improved, but the structural stability may be compromised

Engineering Contradiction:
Improveease of manufactureVSAvoidstructural stability
Core Design Contradiction:
Ease of manufactureVSStability of the object's composition

Solution Approach 1:

The lateral opening is positioned at a specific location on the housing where it provides manufacturing advantages. The opening dimensions and shape are optimized for the specific cartridge insertion angle, making assembly easier while the surrounding housing structure maintains overall structural integrity through localized reinforcement.

Inventive Principle:
Principle #3Local quality
