Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If liquid guide cotton is used in the atomizing core, then liquid conduction is achieved, but liquid leakage and uneven liquid distribution occur due to poor supporting force and uneven gaps
Solution Approach 1:
The liquid guide structure is segmented into multiple longitudinal liquid guide grooves and transverse liquid guide grooves, dividing the liquid conduction path into discrete channels. This segmentation ensures uniform liquid distribution across the atomizing surface and prevents pooling or leakage that occurs with cotton-based guides.
Solution Approach 2:
The liquid guide grooves are designed with specific local geometric properties (cross-sectional shape, dimensions, and arrangement) optimized for capillary action. The grooves provide localized controlled liquid flow paths with consistent supporting force, eliminating the uneven gaps characteristic of cotton-based structures.
2Ease of operation
If liquid guide cotton is used, then liquid conduction is possible, but assembly is inconvenient and supporting force is poor
Solution Approach 1:
The liquid guide grooves are integrated directly into the upper cover structure, merging the liquid guide function with the housing component. This integration eliminates separate assembly steps for installing liquid guide cotton and provides consistent structural supporting force throughout the liquid conduction path.
Solution Approach 2:
The grooves are formed as integral features of the upper cover through molding or machining, allowing the structure to self-provide the liquid guide function without requiring additional materials or assembly operations. The supporting force is inherently provided by the rigid cover structure itself.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design enhances uniform liquid conduction to the heating member, preventing liquid leakage and core burning by utilizing capillary tension to offset liquid gravity, while maintaining efficient atomization.
Implementation Method 1
the atomized liquid has a large capillary tension in the transverse liquid guide groove of the liquid guide structure, and the capillary tension can offset part of the gravity of the liquid itself, thereby avoiding the problem of liquid leakage due to its own weight
Implementation Method 2
the heating atomization assembly includes a heating member, and the heating member is electrically connected to the electrode
