Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a porous ceramic vaporization core with a heating film is used, then the device can generate heat to vaporize the liquid substrate, but the heat and mass transfer efficiency is low and e-liquid explosion may occur
Solution Approach 1:
The porous body is divided into multiple unit layers, each containing a liquid storage advantage layer and a liquid locking advantage layer. This segmentation creates a structured approach to liquid management, where different layers perform specialized functions: storing liquid and locking it in place while maintaining controlled access to the heating film, thereby improving both safety and transfer efficiency
Solution Approach 2:
Different regions of the porous body are given different properties through the alternating layers. The liquid storage advantage layers have properties optimized for liquid retention, while the liquid locking advantage layers have properties optimized for controlled liquid release. This local differentiation allows simultaneous optimization of liquid supply stability and heat transfer efficiency in different zones
2Productivity
If the heating film is combined with the porous body surface, then heat transfer can occur, but mass transfer efficiency is limited and e-liquid explosion risk increases
Solution Approach 1:
The liquid locking advantage layers are positioned between the liquid storage layers and the heating film to pre-control liquid access. This preliminary action ensures that liquid is properly regulated before reaching the heating film, preventing premature or excessive liquid accumulation that could lead to explosion while maintaining efficient mass transfer
Solution Approach 2:
The liquid locking advantage layers act as intermediary structures between the liquid storage advantage layers and the heating film. These intermediary layers mediate the liquid transfer process, controlling the rate and amount of liquid reaching the heating film, thus reducing explosion risk while maintaining mass transfer efficiency
