Replaceable Electronic Cigarette Clearomizer for Wick Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic cigarettes suffer from issues such as a non-detachable atomization assembly and a cotton piece that easily burns out, limiting the e-liquid holding capacity and leading to carbonization of the heating wire.
Innovation Solution
The electronic cigarette features a detachable clearomizer with a fiberglass tube and heating wire wrapped in a sleeve, surrounded by a strip of cotton, which enhances e-liquid absorption and prevents heating wire carbonization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed clearomizer is used, then the device structure is simple, but the atomization assembly cannot be replaced
Solution Approach 1:
The atomization assembly is divided into a replaceable clearomizer portion and a fixed battery portion. The clearomizer can be detached and replaced independently, allowing users to replace only the consumable part rather than the entire device. This segmentation resolves the contradiction by enabling replaceability while keeping the battery assembly simple and fixed.
2Reliability
If common cotton is used in the atomization assembly, then the manufacturing cost is low, but the cotton cannot hold e-liquid and is easily burned out
Solution Approach 1:
The patent uses a composite structure consisting of glass fiber tube, heating wire, and cotton arranged in specific layers. The glass fiber tube provides structural support and e-liquid distribution, the heating wire enables heating, and the cotton serves as the wick material. This composite material approach improves reliability by preventing cotton burnout through proper material selection and arrangement, while maintaining ease of manufacture through a straightforward assembly process.
3Reliability
If the cotton strip is properly designed to absorb e-liquid, then carbonization of heating wire is prevented, but the manufacturing precision requirements increase
Solution Approach 1:
The glass fiber tube acts as an intermediary component between the e-liquid storage and the heating wire. It distributes e-liquid evenly to the cotton and heating wire, preventing direct contact between excessive e-liquid and the heating wire, thus preventing carbonization. This intermediary structure simplifies the manufacturing process by providing a built-in e-liquid distribution mechanism that reduces the precision requirements for cotton placement.
4Productivity
If the heating wire is properly positioned and secured, then the atomization efficiency is improved, but the device complexity increases
Solution Approach 1:
The heating wire is merged with the glass fiber tube and cotton assembly as an integrated unit. The heating wire is positioned within the glass fiber tube structure, which provides both support and e-liquid distribution. This merging of components improves atomization efficiency by ensuring proper positioning and integration of the heating element with the e-liquid supply system, while avoiding the need for separate complex positioning mechanisms.
