Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If cool air directly blows the heating element to enhance cooling and atomization, then atomization amount increases, but heating efficiency decreases
Solution Approach 1:
A fluid-guide member is introduced as an intermediary component between the air inlet and the atomizing core. This mediator redirects the cool air flow along the side surface of the atomizing core to the atomizing surface, preventing direct contact between cool air and the heating element while still enabling effective atomization. The fluid-guide member acts as a buffer that separates the conflicting requirements of cooling for atomization and heating for efficiency.
Solution Approach 2:
The air flow path is segmented into different zones: a first air inlet for introducing cool air, a fluid-guide member that directs this air along the side surface, and a second air inlet for introducing additional air. This segmentation allows different portions of air to serve different functions - one portion cools and facilitates atomization while another portion maintains heating efficiency, resolving the contradiction between atomization amount and heating efficiency.
2Quantity of substance
If cool air directly contacts the heating element to improve atomization, then atomization amount increases, but heating element temperature stability deteriorates
Solution Approach 1:
The fluid-guide member serves as a thermal buffer and flow mediator that prevents direct thermal exchange between cool air and the heating element. By redirecting air flow along the side surface and directing it toward the atomizing surface, the intermediary structure maintains temperature stability of the heating element while still enabling sufficient cooling and atomization at the atomizing surface.
3Speed
If air inlet is positioned close to atomizing core for efficient cooling, then cooling efficiency improves, but heating efficiency deteriorates
Solution Approach 1:
The air inlet system is segmented into multiple functional inlets: a first air inlet positioned to introduce cool air that is redirected by the fluid-guide member along the side surface for efficient cooling without direct heating element contact, and a second air inlet that introduces additional air to maintain heating efficiency. This segmentation resolves the spatial conflict between cooling efficiency and heating efficiency.
Solution Approach 2:
The fluid-guide member utilizes the side surface dimension of the atomizing core to redirect air flow. Instead of direct linear flow from air inlet to heating element, the air is guided along the lateral dimension (side surface) and then directed to the atomizing surface, creating a three-dimensional flow path that maintains both cooling and heating efficiency.

AI summary
The present disclosure provides an atomization assembly (1) and an electronic atomization device. The atomization assembly (1) includes an atomizing core (11), an air inlet (12), and a fluid-guide member (13). The fluid-guide member (13) is disposed between the air inlet (12) and the atomizing core (11). The fluid-guide member (13) and the air inlet (12) are arranged at intervals, and the fluid-guide member (13) shields the bottom of the atomizing core (11). In this way, the fluid-guide member (13) may prevent the cool air entering from the air inlet (12) from directly blowing the atomizing core (11), such that it is possible to prevent the heating efficiency of the atomizing core (11) from being affected by the cool air, thus it is beneficial to ensure the atomization amount of the atomizing assembly (1), thus improving the user experience.
