Solution Overview
Problem
Existing heating atomization assemblies face issues with local oil explosions, core overburning, and poor atomization stability due to inconsistent liquid conducting cotton arrangements, leading to harmful substance generation and consumer experience degradation.
Innovation Solution
A heating unit with an intermediate portion and end portions, featuring an accommodating space with a smaller sectional area at the intermediate portion compared to the end portions, ensuring better contact and liquid supply stability by varying the radial dimensions and sectional area configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a liquid conducting cotton rope with consistent thickness is used and arranged in the inner hole of the heating unit, then the structure is simple and easy to manufacture, but local parts of the liquid conducting cotton may be subjected to oil explosion or core overburning, and atomization stability is poor
Solution Approach 1:
The heating unit employs different structural configurations at different locations: the intermediate portion has a smaller inner diameter while the end portions have larger inner diameters. This local variation in geometry creates different accommodating spaces that optimize both liquid conduction and heating contact at each location, resolving the contradiction between manufacturing simplicity and atomization stability
Solution Approach 2:
The heating unit is divided into distinct segments (intermediate portion and end portions) with different functional characteristics. The intermediate portion focuses on heating efficiency with tighter contact, while end portions focus on liquid supply with more space, achieving stable atomization through segmented functional zones
2Stability of the object's composition
If the liquid conducting cotton is arranged in the inner hole of the heating unit with consistent thickness, then the structure is uniform and simple, but the heating unit cannot maintain stable contact with the liquid conducting cotton, leading to core overburning
Solution Approach 1:
The heating unit implements local quality variation through different inner diameters at intermediate and end portions. This creates locally optimized accommodating spaces that ensure stable contact between the heating unit and liquid conducting cotton where needed, while maintaining overall structural simplicity
Solution Approach 2:
The inner diameter parameter of the heating unit is changed along its length, with the intermediate portion having a smaller diameter than the end portions. This parameter variation optimizes the contact pressure and thermal transfer efficiency at different locations, ensuring heating stability
3Quantity of substance
If the heating unit has a larger inner diameter throughout, then liquid supply is adequate, but contact between the heating unit and liquid conducting cotton is insufficient, causing oil explosion and harmful substance generation
Solution Approach 1:
The heating unit creates different accommodating space characteristics at intermediate and end portions. The intermediate portion's smaller inner diameter ensures tight contact for safe heating, while end portions provide adequate space for liquid supply, eliminating the harmful effects of both insufficient contact and insufficient liquid supply
Solution Approach 2:
The intermediate portion acts as an intermediary zone with optimized geometry that mediates between the liquid supply function at end portions and the heating safety requirement. This intermediate structure ensures both adequate liquid delivery and secure heating contact
