E-vaping Mouth-end Insert Heat Absorption and Vapor Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
E-vaping devices often produce vapor at high temperatures, which can be uncomfortable for users and may lead to the formation of harsh aerosol droplets, necessitating a solution to reduce vapor temperature and improve distribution.
Innovation Solution
The e-vaping device incorporates a mouth-end insert with eight angled outlets that distribute vapor, featuring a surface area designed to absorb heat and reduce vapor temperature to between 60° C and 70° C, along with a specific geometry and material selection to optimize vapor exit velocity and distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If vapor is delivered directly through a single outlet, then the vapor delivery system is simple, but the vapor temperature remains high and distribution is poor
Solution Approach 1:
The mouth-end insert is divided into multiple outlets (at least eight) instead of a single outlet, segmenting the vapor flow path. This segmentation distributes vapor across multiple exit points, reducing the temperature of vapor at each outlet while improving overall distribution. The segmentation principle directly addresses the contradiction by breaking down the single high-temperature flow into multiple lower-temperature flows.
Solution Approach 2:
The outlets are arranged in a specific geometric pattern with at least eight outlets positioned around the circumference of the mouth-end insert. This dimensional arrangement transforms the vapor delivery from a single-point (0D) or linear (1D) flow to a distributed three-dimensional (3D) flow pattern, enabling better heat dissipation and temperature reduction while maintaining structural simplicity.
2Ease of operation
If vapor exits at high velocity, then vapor delivery efficiency is high, but droplet formation increases and comfort decreases
Solution Approach 1:
Each outlet is designed with specific local geometric characteristics, including angled orientations (at least 45 degrees relative to the longitudinal axis) and specific diameter ranges (0.015 to 0.090 inch). These localized quality variations at each outlet create optimal flow conditions that balance vapor delivery efficiency with comfort, reducing droplet formation while maintaining adequate vapor flow velocity.
Solution Approach 2:
The outlet parameters (angle, diameter, shape) are specifically optimized to change the vapor flow characteristics. By adjusting these parameters, the system achieves an optimal balance between exit velocity and droplet formation, improving vaping comfort without significantly compromising vapor delivery efficiency. The tear-drop shape and angular orientation are specific parameter changes that address this contradiction.
3Stability of the object's composition
If outlet area is increased, then vapor distribution improves, but vapor velocity decreases
Solution Approach 1:
The total outlet area is segmented into at least eight individual outlets distributed around the mouth-end insert circumference. This segmentation allows the system to achieve good vapor distribution uniformity (by spreading outlets across the circumference) while maintaining adequate exit velocity (by keeping individual outlet areas within optimal ranges). The segmentation enables both distribution and velocity requirements to be satisfied simultaneously.
Solution Approach 2:
The outlets are arranged in a three-dimensional spatial configuration around the circumference rather than in a single plane or line. This dimensional arrangement allows vapor to be distributed uniformly in multiple directions while maintaining flow velocity through the angled outlet orientations, resolving the contradiction between distribution uniformity and exit velocity.
