Solution Overview

Problem

Conventional electronic cigarettes have non-refillable cartomizers and integrated atomizers, which are difficult to replace when they break down, and often use seals that are cumbersome to install and maintain.

Innovation Solution

An electronic cigarette design featuring a rotatable ring to adjust air and vapor volume, a refillable cartomizer, and a detachable atomizer, with seals and a silicone base for easy installation and replacement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the air passage is fixed, then the structure is simple, but the user cannot adjust the volume of air and vapor

Engineering Contradiction:
Improveadjustability of air and vapor volumeVSAvoidstructure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The air passage is designed as a rotatable ring structure that can rotate around the atomizer, dynamically changing the cross-sectional area of the air passage. This allows the user to adjust the volume of air and vapor by rotating the ring to different positions, transforming a static structure into a dynamic one that adapts to user needs.

Inventive Principle:
Principle #15Dynamics

2Ease of repair

If the atomizer is fixed to the cartomizer, then the structure is stable, but the atomizer cannot be replaced or cleaned

Engineering Contradiction:
Improvereplaceability and cleanability of atomizerVSAvoidconnection stability
Core Design Contradiction:
Ease of repairVSReliability

Solution Approach 1:

The atomizer is designed as a separate, replaceable component that can be independently removed from the cartomizer. The air passage ring can be detached from the atomizer body, allowing users to replace or clean the atomizer without disassembling the entire device, thus maintaining connection stability while enabling easy maintenance.

Inventive Principle:
Principle #1Segmentation

3Productivity

If the air passage cross-sectional area is large, then the air and vapor flow is smooth, but the device size increases

Engineering Contradiction:
Improveair and vapor flow efficiencyVSAvoiddevice size
Core Design Contradiction:
ProductivityVSVolume of moving object

Solution Approach 1:

The rotatable ring structure allows the air passage cross-sectional area to be dynamically adjusted. When high flow efficiency is needed, the ring can be positioned to maximize the opening area. When device compactness is prioritized, the ring can be rotated to reduce the effective area, thus optimizing the balance between flow efficiency and device size based on usage conditions.

Inventive Principle:
Principle #15Dynamics
