Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing atomizing devices in electronic cigarettes face issues of poor contact between the heating member and liquid conducting material, leading to dry burning and deformation, due to the high frequency of use and short working time, which is exacerbated by the thin diameter of the heating wire and the need for rapid heating to the boiling point of atomizable liquids.
Innovation Solution
An atomizing assembly is designed with a flexible first liquid conducting member and a heating assembly fixed through sewing, where the heating assembly includes interwoven flexible first and second wires, ensuring good contact and stability, and electrodes are connected to the heating assembly for efficient atomization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the heating member uses a thin wire with small cross-sectional area to meet resistance requirements, then the electrical resistance is appropriate, but the strength is poor and deformation occurs easily
Solution Approach 1:
The heating member is divided into multiple wire segments (first wire and second wire) that are interwoven together. Each wire can be made with appropriate thickness for resistance control, while the combined structure provides enhanced strength and deformation resistance through the interwoven configuration.
Solution Approach 2:
The heating member uses a composite structure of interwoven wires with different properties. The first wire and second wire are interwoven to create a composite heating element that combines the electrical resistance properties of thin wires with the mechanical strength of multiple intertwined conductors.
2Speed
If the heating member is thin to achieve rapid heating to boiling point, then the heating speed is fast, but the contact with liquid conducting material is poor leading to dry burning
Solution Approach 1:
The heating member is segmented into interwoven first and second wires, creating multiple contact points with the liquid conducting material. This segmentation ensures that even if one wire has poor contact, other wires maintain reliable contact, preventing dry burning while maintaining rapid heating capability.
Solution Approach 2:
The interwoven structure of the heating member creates varying local contact characteristics with the liquid conducting material. Different regions of the interwoven wires provide different contact qualities, ensuring that sufficient contact areas are maintained for reliable heating without requiring uniformly thick wires throughout.
3Productivity
If the heating member is thin for rapid heating, then the heating efficiency is high, but the device is prone to deformation under frequent use
Solution Approach 1:
The heating member is segmented into multiple interwoven wire segments rather than a single thin wire. This segmentation allows each segment to be optimized for heating efficiency while the collective interwoven structure provides the structural stability needed to resist deformation during frequent use.
Solution Approach 2:
The interwoven wires are configured to follow curved paths and interlace with each other, creating a flexible yet stable three-dimensional structure. This curved, interwoven configuration distributes mechanical stresses more effectively than a straight thin wire, preventing deformation under frequent bending and use.
