Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a tubular element is used to guide e-liquid flow, then e-liquid distribution is improved, but the risk of leakage increases
Solution Approach 1:
The patent employs a nested structure where the second e-liquid guide element is positioned inside the tubular element, and the first e-liquid guide element surrounds the tubular element. This nested arrangement allows the e-liquid guide elements to constrain and direct the e-liquid flow through the tubular element, preventing leakage while maintaining efficient distribution. The concentric positioning of multiple guide elements creates a controlled pathway that eliminates gaps and prevents e-liquid from escaping the intended flow path.
2Productivity
If multiple e-liquid guide elements are added to improve absorption, then e-liquid absorption efficiency is improved, but device complexity increases
Solution Approach 1:
The patent divides the e-liquid guide function into multiple segmented elements: a first e-liquid guide element for initial e-liquid absorption from the storage cavity, and a second e-liquid guide element for secondary absorption and directed flow to the heating element. This segmentation allows each element to perform a specific function in the e-liquid transport pathway, improving overall absorption efficiency while maintaining a modular and manageable structure that can be assembled systematically.
Solution Approach 2:
The tubular element serves multiple functions simultaneously: it acts as a structural support for the second e-liquid guide element, provides a defined pathway for e-liquid flow, and works in conjunction with the first e-liquid guide element to create a multi-stage absorption system. This multi-functionality reduces the need for additional separate components, thereby managing device complexity while improving e-liquid absorption efficiency.
3Quantity of substance
If gaps are added to buffer e-liquid, then e-liquid storage capacity is improved, but the risk of leakage increases
Solution Approach 1:
The patent introduces gaps at specific localized positions between the e-liquid guide elements and the tubular element, rather than throughout the entire structure. These strategically placed gaps provide localized e-liquid buffering capacity to store excess e-liquid temporarily, while the continuous contact between the guide elements and the tubular element at other positions maintains effective flow control and prevents leakage. This selective application of gaps optimizes both storage capacity and leakage prevention.

AI summary
Provided in the present application are an atomizer and an electronic atomization device. The atomizer comprises: an e-liquid storage cavity; a first e-liquid guide element, which is arranged perpendicular to the longitudinal direction of the atomizer and is in fluid communication with the e-liquid storage cavity so as to suction a liquid matrix; a tubular element, which penetrates the first e-liquid guide element; a second e-liquid guide element, which is located in the tubular element and indirectly suctions from the first e-liquid guide element the liquid matrix which is from the e-liquid storage cavity; a heating element, which is combined with the second e-liquid guide element and is used for heating at least part of the liquid matrix held in the second e-liquid guide element so as to generate an aerosol; and a support, which at least partially accommodates and surrounds the first e-liquid guide element, and supports or holds part of the tubular element. In the atomizer, the support accommodates and surrounds the first e-liquid guide element suctioning the liquid matrix from the e-liquid storage cavity and supports or holds the tubular element, so that the second e-liquid guide element in the tubular element indirectly suctions the liquid matrix in the e-liquid storage cavity and then heats and atomizes same to generate an aerosol.
