Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fiber rope or composite cotton is used for liquid guiding, then liquid can be delivered to the heating wire, but dry burning occurs when insufficient liquid infiltrates the liquid guiding member
Solution Approach 1:
The patent replaces the traditional fiber-based liquid guiding system with a capillary channel structure. The capillary channels provide controlled liquid transport pathways that ensure sufficient liquid reaches the heating wire, eliminating the dry burning issue associated with fiber rope while maintaining reliable liquid delivery through capillary action.
Solution Approach 2:
The patent utilizes the porous structure of the liquid guiding member with controlled capillary channels. The porous material enables capillary action to draw liquid from the storage chamber through the liquid guiding member to the heating wire, ensuring consistent liquid supply and preventing dry burning conditions.
2Reliability
If large amount of e-cigarette liquid infiltrates on the liquid guiding member, then liquid supply is sufficient, but liquid leakage occurs when too much liquid cannot be consumed
Solution Approach 1:
The patent segments the liquid guiding member into multiple capillary channels with controlled dimensions. This segmentation limits the total liquid capacity within the liquid guiding member, allowing sufficient liquid supply for atomization while preventing excessive liquid accumulation that would cause leakage. The segmented structure controls liquid flow distribution to match consumption rates.
3Device complexity
If traditional liquid guiding structures are used, then device structure is simple, but liquid level control in atomizing chamber is inadequate
Solution Approach 1:
The patent implements a self-regulating liquid level control system where the capillary channels automatically adjust liquid flow based on liquid level in the atomizing chamber. When liquid level is high, capillary action naturally reduces flow; when liquid level is low, capillary action increases flow. This self-service mechanism provides reliable liquid level control without adding complex external control systems.

AI summary
Disclosed is an electronic cigarette, comprising a liquid storage device (120) and an atomization device (110). The liquid storage device (120) comprises a liquid storage cavity (121). The atomization device (110) comprises an atomization cavity (111). The electronic cigarette further comprises a control unit (140) and an actuating mechanism (150), the control unit (140) being electrically connected to and in linkage control with the actuating mechanism (150), and the control unit (140) controlling the actuating mechanism (150) so same drives e-liquid in the liquid storage cavity (121) to enter the atomization cavity (111) when the control unit (140) controls the liquid feed of the electronic cigarette. With such an electronic cigarette, the amount of e-liquid, in the liquid storage cavity and entering the atomization device (110), driven by the actuating mechanism (150) is controlled by the control unit (140), and control over the amount of e-liquid in the atomization device (110) can be achieved, that is, when inhaling, it can be ensured that there is an appropriate amount of e-liquid in the atomization device (110) so as to avoid the phenomena of burning without liquid and the leakage of liquid due to insufficient atomization.
