Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic cigarette atomizing devices face issues with e-liquid leakage and condensation of vapor, leading to a poor user experience due to high airflow velocity and narrow vapor transportation pipes.
Innovation Solution
The atomizing device features a non-linear airflow channel, a ladder-like liquid flow channel, and a separate vapor transportation pipe to prevent e-liquid leakage and condensation, with a microporous ceramic rod and heating coil for efficient e-liquid absorption and vapor generation, and a funnel-shaped vapor pipe mounting part to slow down vapor flow and prevent condensed e-liquid from entering the mouth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the vapor transportation pipe has a small inner diameter, then the device structure is compact, but the airflow velocity becomes too high causing vapor condensation and poor user experience
Solution Approach 1:
The vapor transportation path is divided into multiple sections with different diameters. The pipe has a first section with a first inner diameter and a second section with a second inner diameter that is larger than the first. This segmentation allows the vapor to be transported through a narrower initial section for compactness while expanding to a larger diameter section to reduce airflow velocity and prevent condensation.
Solution Approach 2:
The patent introduces a dimensional change in the vapor transportation pipe by varying the inner diameter along the flow path. Instead of using a uniformly small diameter, the pipe transitions from a smaller first inner diameter to a larger second inner diameter, effectively using spatial dimensionality to resolve the contradiction between compact structure and acceptable airflow velocity.
2Strength
If the holder is made of metal hardware component, then the structure is strong and durable, but the e-liquid leaks from the gap between the holder and the liquid absorbing unit
Solution Approach 1:
An intermediary component (sealing ring or sealing structure) is introduced between the metal holder and the liquid absorbing unit to prevent e-liquid leakage. This intermediary element fills the gap between the rigid metal holder and the liquid absorbing unit, maintaining the structural strength of the metal holder while eliminating the harmful leakage effect.
Solution Approach 2:
The patent employs flexible sealing elements (such as sealing rings or elastic sealing structures) between the rigid metal holder and the liquid absorbing unit. These flexible components can deform to fill gaps and prevent e-liquid leakage while maintaining the overall structural integrity provided by the metal holder.
3Productivity
If the liquid absorbing unit extends out of the holder, then the e-liquid absorption is efficient, but the e-liquid leaks from the gap between the holder and the liquid absorbing unit
Solution Approach 1:
A sealing intermediary is introduced between the holder and the liquid absorbing unit to prevent leakage while maintaining the extended configuration of the liquid absorbing unit. This allows the liquid absorbing unit to remain positioned for efficient e-liquid absorption from the liquid storage chamber while the sealing intermediary prevents e-liquid from leaking through the gap.
Solution Approach 2:
Flexible sealing structures are used to accommodate the extended liquid absorbing unit while preventing e-liquid leakage. These flexible sealing elements can adapt to the position of the liquid absorbing unit, ensuring both efficient absorption and leak prevention.
