Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic cigarettes have a fixed atomizer that is difficult to repair or replace, and there is a risk of e-liquid leakage during e-liquid injection.
Innovation Solution
The electronic cigarette design includes a detachable atomization assembly with a funnel mechanism for easy repair or replacement of the atomizer and a pneumatic switch to prevent e-liquid leakage by controlling air flow, utilizing magnets for assembly connection and a dual air inlet system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the atomizer is fixedly disposed in conventional electronic cigarettes, then the structural stability is improved, but the ease of repair and replacement deteriorates
Solution Approach 1:
The electronic cigarette is divided into separable modules: the atomization assembly (containing the atomizer) and the power supply assembly (containing the battery). These modules are connected through magnetic attraction between first magnets in the base and second magnets in the housing, allowing easy separation and recombination without tools while maintaining stable operation when assembled.
2Ease of repair
If a detachable atomization assembly is used, then the ease of repair and replacement is improved, but the structural stability deteriorates
Solution Approach 1:
The traditional mechanical connection (screws, clips, or snap-fits) is replaced with magnetic attraction between first magnets embedded in the base and second magnets in the housing. This provides a tool-free, reversible connection that is easy to assemble and disassemble while maintaining sufficient structural stability during normal use.
3Ease of operation
If e-liquid is injected directly into the atomizer, then the ease of operation is improved, but the risk of leakage increases
Solution Approach 1:
A funnel is introduced as an intermediary tool between the e-liquid source and the atomizer. The funnel guides the e-liquid flow into the atomizer chamber through its narrow outlet, preventing splashing and overflow. The funnel can be easily inserted and removed, making the refilling process simple while eliminating leakage risks associated with direct injection.
