Solution Overview

Problem

The existing electronic cigarette atomizers face challenges with complex and costly magnetic connections, thermal expansion issues leading to component looseness, and reduced sealing effectiveness due to material deformation during heating.

Innovation Solution

An atomizer design featuring a metal fixing member with a tabular main body portion that uses magnets for secure attachment to the power supply assembly, eliminating the need for magnets on the atomizer, and incorporating a connecting portion for stable fixation and reduced thermal expansion effects.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Force

If magnets are installed at both ends of the atomizer and power supply assembly to ensure adsorption, then the magnetic connection strength is improved, but the cost increases and assembling becomes more cumbersome

Engineering Contradiction:
Improvemagnetic adsorption forceVSAvoidassembly complexity
Core Design Contradiction:
ForceVSDevice complexity

Solution Approach 1:

The patent extracts the magnet from one side of the magnetic connection system. Specifically, magnets are installed only on the power supply assembly (receptacle side), and the atomizer side uses a magnet-receptive structure without magnets. This extraction reduces component count and assembly complexity while maintaining sufficient magnetic adsorption force through optimized magnet size and strength on the power supply assembly.

Inventive Principle:
Principle #2Taking out (Extraction)

2Ease of manufacture

If plastic or silica gel materials are used for the atomizing base, then manufacturing ease is improved, but thermal expansion and cold shrinkage cause deformation and looseness during heating

Engineering Contradiction:
Improvemanufacturing easeVSAvoiddimensional stability
Core Design Contradiction:
Ease of manufactureVSStability of the object's composition

Solution Approach 1:

The patent employs composite material construction for the atomizing base, combining metal components (fixing member, connecting portion) with the atomizing base material. The metal fixing member provides dimensional stability and resistance to thermal expansion, while the atomizing base material maintains manufacturing ease. This composite approach allows each material to contribute its superior properties to the overall structure.

Inventive Principle:
Principle #40Composite materials

3Ease of operation

If flexible materials are used for fiber rope and heating wire, then ease of installation is improved, but fixing structures become relatively complicated

Engineering Contradiction:
Improveinstallation easeVSAvoidfixing structure complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent segments the fixing function into distinct components: the fixing member with connecting portion separately handles the fiber rope and heating wire fixation. This segmentation allows the flexible materials to be installed independently without requiring complex integrated fixing structures, simplifying the overall fixing system while maintaining installation ease.

Inventive Principle:
Principle #1Segmentation

AI summary

The present utility relates to an electronic cigarette and an atomizer (1) thereof. The atomizer comprises an atomizing body (11), an atomizing base (14) disposed at one end of the atomizing body, and a fixing member (15) installed outside the atomizing base and connected with the atomizing body. The atomizing base is fixed on the atomizing body by the fixing member, and the fixing member is made of a material that can be adsorbed by a magnet and comprises a tabular main body portion corresponding to the atomizing base. The atomizing base is fixed on the atomizing body by the fixing member, and after the atomizer is connected and assembled with a power supply assembly (2), an adsorption force between the tabular main body portion and the magnet can increase. As an area of the fixing member corresponding to the power supply assembly is large enough, the adsorption force between the fixing member and the magnet on the power supply assembly is strong enough, so that it is not necessary to provide the atomizer with the magnet, and thus the cost can be reduced.
