Atomizing Core Conductive Assembly for E-Liquid Leakage Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic atomization devices are prone to liquid leakage due to excessively rapid drainage from the liquid storage cavity, which is exacerbated by the saturation of conductive members, leading to oversaturation and leakage of the aerosol-forming medium.
Innovation Solution
The atomizing core incorporates a conductive assembly with a first and second conductive member, where a limiting portion between them reduces fluid conduction capability, ensuring that excess aerosol-forming medium is absorbed by the second conductive member when the mounting member becomes saturated, thereby preventing leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the conductive member is designed to rapidly drain the aerosol-forming medium from the liquid storage cavity, then the drainage speed is improved, but liquid leakage occurs due to oversaturation
Solution Approach 1:
The conductive member is divided into a first conductive member and a second conductive member with different conduction capabilities. The first conductive member provides rapid drainage through the mounting member, while the second conductive member with limited conduction capability prevents oversaturation by restricting excess flow, thus resolving the contradiction between fast drainage and leakage prevention.
Solution Approach 2:
Different regions of the conductive assembly are assigned different fluid conduction properties. The first conductive member has high conduction capability for rapid drainage, while the second conductive member has limited conduction capability to prevent oversaturation. This local differentiation allows simultaneous achievement of fast drainage and leakage prevention.
2Quantity of substance
If the conductive member absorbs excessive aerosol-forming medium, then the medium is retained in the device, but the conductive member becomes saturated leading to leakage
Solution Approach 1:
The conductive member is segmented into two functional parts: the first conductive member that absorbs and retains the aerosol-forming medium, and the second conductive member with limited conduction capability that acts as a safety mechanism to prevent oversaturation and subsequent leakage.
Solution Approach 2:
The second conductive member serves as an intermediary safety mechanism between the first conductive member and the liquid storage cavity. It mediates the fluid flow by limiting the conduction capability, preventing the first conductive member from becoming oversaturated and leaking.
3Productivity
If the fluid conduction capability between conductive members is high, then the aerosol-forming medium flows smoothly, but the device usage time is reduced due to leakage
Solution Approach 1:
The conductive assembly is segmented into two members with different conduction capabilities. The first conductive member maintains high flow efficiency for smooth aerosol-forming medium flow, while the second conductive member with limited capability prevents oversaturation-induced leakage that would reduce device usage time.
Solution Approach 2:
The fluid conduction capability parameter is differentiated between the first and second conductive members. The first member has high conduction capability for efficient flow, while the second member has reduced conduction capability to prevent oversaturation, thereby extending device usage time without significantly compromising flow efficiency.
