Solution Overview
Problem
Existing aerosol generating devices face challenges in maintaining waterproof, heat-resistant, and corrosion-resistant structures, particularly at coupling portions where separate waterproof members are prone to deformation or damage under high temperatures.
Innovation Solution
An aerosol generating device with an integrated inner wall, coil, and heating body structure, where the heating body and supporting portion are integrally formed with the inner wall, providing a waterproof structure without separate waterproof members, and using materials like glass or ceramic for enhanced resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate waterproof members are installed at coupling portions, then waterproofing is achieved, but the structure deforms or damages under high temperatures
Solution Approach 1:
The patent merges the heating body and supporting portion into a single integrated structure formed by sintering ferromagnetic powder and binder material. This integration eliminates separate waterproof members at coupling portions, preventing deformation or damage under high temperatures while maintaining waterproof integrity through the monolithic structure.
2Reliability
If separate waterproof members are used at coupling portions, then waterproofing is provided, but the number of parts and assembly complexity increases
Solution Approach 1:
The heating body and supporting portion are combined into a single sintered component, eliminating the need for separate waterproof members and reducing assembly steps. This integration simplifies the overall structure while maintaining reliable waterproofing through the unified design.
3Power
If traditional heating structures are used, then heating function is provided, but corrosion resistance and chemical resistance are insufficient
Solution Approach 1:
The patent uses a composite material system consisting of ferromagnetic powder (providing heating function through induction), binder material (providing structural integrity), and optional ceramic particles (enhancing corrosion and chemical resistance). This composite structure maintains heating effectiveness while improving resistance to harsh environments.
