Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vaporizers face issues with excessive liquid substrate supply, leading to incomplete vaporization and the formation of large droplets, which affect the user's inhaling experience due to mismatched liquid guide rates and vaporization efficiencies.
Innovation Solution
A vaporizer design featuring a liquid guide element with an extension portion that extends away from the liquid storage cavity, allowing for buffering of excessive liquid substrates in an accommodation cavity farther from the heating element, preventing accumulation and sputtering sounds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the liquid guide element uses a capillary element with better liquid guide performance, then the liquid guide rate increases, but the liquid substrate accumulates and cannot be vaporized in time, causing sputtering sounds and large droplets
Solution Approach 1:
The liquid guide element is segmented into a main body portion and an extension portion. The extension portion extends into the accommodation cavity to provide additional liquid storage capacity, while the main body portion remains in the vaporization cavity for active vaporization. This segmentation allows the system to handle higher liquid guide rates without accumulation problems.
Solution Approach 2:
The liquid guide element extends in a new spatial dimension by projecting the extension portion into the accommodation cavity, which is located farther from the liquid storage cavity than the heating element. This dimensional extension creates additional buffer space for liquid substrate without interfering with the heating element's operation.
2Productivity
If the liquid guide rate is excessively high, then more liquid substrate is supplied to the heating element, but heat generated is limited per unit time, causing incomplete vaporization and droplet formation
Solution Approach 1:
The extension portion of the liquid guide element acts as a preliminary buffer zone that cushions excess liquid substrate before it reaches the heating element. By providing this advance cushioning capacity in the accommodation cavity, the system prevents liquid accumulation that would otherwise lead to sputtering and droplet formation during high liquid guide rate operation.
3Speed
If the accommodation cavity is positioned closer to the liquid storage cavity, then liquid substrate transfer is more efficient, but liquid substrate may accumulate near the heating element and cause sputtering
Solution Approach 1:
Instead of positioning the accommodation cavity closer in the longitudinal direction (which would cause accumulation near the heating element), the extension portion of the liquid guide element utilizes a different spatial dimension by extending into the accommodation cavity from the vaporization cavity. This dimensional approach maintains efficient liquid transfer while preventing harmful accumulation near the heating element.
