Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a heating wire or screen printed heating film is used on a ceramic substrate, then the heating body achieves simple structure and high vaporization efficiency, but slow aerosol formation and dry heating occur
Solution Approach 1:
The heating body is segmented into two functional zones: a preheating zone with a heating wire embedded in the ceramic substrate, and a vaporization zone with a heating film screen-printed on the ceramic substrate. This segmentation allows the preheating zone to warm the liquid medium first, improving fluidity and preventing dry heating, while the vaporization zone efficiently generates aerosol, thus resolving the contradiction between vaporization efficiency and aerosol formation speed.
Solution Approach 2:
The preheating member performs preliminary heating action on the liquid medium before it reaches the vaporization zone. By preheating the liquid to improve its fluidity, the system ensures that liquid is always available for vaporization, preventing dry heating and ensuring reliable aerosol formation while maintaining high vaporization efficiency.
2Ease of manufacture
If conventional heating bodies are used, then结构简单 and high vaporization efficiency is achieved, but burnt flavor and miscellaneous air are generated due to dry heating
Solution Approach 1:
The heating body is divided into a preheating member with heating wire and a vaporization member with heating film, both on a ceramic substrate. The preheating member prevents dry heating by ensuring liquid availability, eliminating burnt flavor, while the overall structure remains simple and easy to manufacture.
Solution Approach 2:
The ceramic substrate acts as an intermediary thermal management layer between the heating wire and the liquid medium. It distributes heat uniformly and maintains liquid contact with the heating surface, preventing localized dry heating and burnt flavor while preserving structural simplicity.
3Temperature
If heating wire is pre-embedded in ceramic substrate, then uniform temperature field is achieved, but dry heating and slow aerosol formation occur
Solution Approach 1:
The heating body segments thermal management into preheating and vaporization zones. The preheating zone with heating wire provides uniform temperature field to improve liquid fluidity, while the vaporization zone with heating film ensures rapid aerosol formation, resolving the contradiction between temperature uniformity and aerosol formation speed.
