Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In electronic cigarettes, the small contact surface between the heating wire and glass fiber core leads to scorched flavors due to high temperatures over time, affecting the quality of vaporized tobacco liquid.
Innovation Solution
An atomizer design featuring a shell with a liquid supply and atomizing assembly, including a porous liquid conducting element, a heating disk, and a liquid absorbing body, where the heating disk is separated from direct contact with the liquid conducting element, using a silica sleeve for sealing and air passage to prevent liquid leakage and enhance vaporization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a heating wire is wound around a glass fiber core to heat tobacco liquid, then the heating function is achieved, but the small contact surface causes high temperature concentration and scorched flavors over time
Solution Approach 1:
The patent introduces a liquid-saturated porous material as an intermediary between the heating wire and the tobacco liquid. This intermediary increases the contact surface area for heat transfer, distributing the thermal energy more evenly and preventing localized high temperatures that cause scorching. The porous material absorbs and holds liquid, allowing gradual heating without direct contact between the heating wire and bulk liquid.
Solution Approach 2:
The patent employs a porous material (such as porous ceramic, porous metal, or porous fiber) that is saturated with liquid. The porous structure provides a large internal surface area for heat transfer while maintaining liquid retention. This resolves the contradiction by enabling efficient heating through the extensive surface area of the porous structure without creating hot spots that lead to scorching.
2Productivity
If the heating wire directly contacts the liquid conducting element, then heating efficiency is improved, but liquid leakage occurs and flavor quality deteriorates
Solution Approach 1:
The patent segments the heating system into distinct functional zones: a liquid conducting element that transports tobacco liquid, a porous material that holds and distributes the liquid, and a heating wire that provides thermal energy. This segmentation allows each component to perform its specific function optimally while preventing liquid leakage through proper separation of liquid-handling and heating functions.
Solution Approach 2:
The porous material serves as an intermediary layer between the liquid conducting element and the heating wire. It absorbs and retains the liquid, allowing controlled transfer to the heating zone while preventing direct contact between the heating wire and excess liquid, thereby preventing leakage and maintaining flavor quality.
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 solution effectively prevents liquid leakage and improves flavor quality by allowing for efficient vaporization of tobacco liquid without direct contact between the heating element and the liquid conducting element, reducing the risk of scorched flavors and maintaining aerosol production.
