E-Cigarette Capsule Transverse Vaporization Path for Compact Volume
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic cigarette capsules lack efficient vapor generation capabilities, resulting in inconsistent and smaller volumes of vapor, and often compromise on compactness.
Innovation Solution
A capsule design with a vaporization flow path extending substantially perpendicular to the axial direction, incorporating a heating element with a capillary-type structure and a seal to optimize liquid delivery, and a vapor flow path that maximizes contact with the heating surface, ensuring a larger and more consistent vapor production while maintaining compactness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the vaporization flow path is extended in the axial direction, then the vapor generation volume increases, but the capsule length increases compromising compactness
Solution Approach 1:
The vaporization flow path is reoriented from a longitudinal axial arrangement to a transverse arrangement perpendicular to the capsule axis. This dimensional change allows the vaporization flow path to extend across the width of the capsule rather than along its length, increasing vapor generation volume while preserving compact capsule dimensions.
2Reliability
If the heating element surface area is increased, then vapor generation consistency improves, but capsule volume increases
Solution Approach 1:
The heating element is repositioned and reoriented to maximize its surface area exposure to the vaporization flow path. By arranging the heating element perpendicular to the capsule axis and aligning it with the transverse vaporization flow path, the heating surface area is optimized within the constrained capsule volume, improving vapor generation consistency without increasing overall capsule size.
3Object-affected harmful factors
If the vapor flow path is lengthened, then vapor cooling is improved, but the distance from heating element increases reducing heating efficiency
Solution Approach 1:
The vapor flow path is configured to extend perpendicular to the capsule axis, allowing vapor to travel a sufficient distance for cooling while remaining in close proximity to the heating element. This transverse arrangement enables the vapor flow path to be lengthened for cooling purposes without significantly increasing the distance from the heating element, thus maintaining heating efficiency while achieving adequate vapor temperature control.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design enhances vapor generation by heating a greater proportion of the vaporization flow path, producing a larger and more consistent vapor volume, while ensuring the capsule remains compact and safe by allowing sufficient vapor cooling before inhalation.
Implementation Method 1
A heating element is housed within the vaporising chamber, the heating element being configured to vaporise liquid received from the storage reservoir and generate a vapour
Implementation Method 2
the wick must be arranged between the liquid store and vaporization chamber such that, when the wick is heated, capillary action transports liquid through the porous structure of the wick from the liquid store to the heating element
