Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If porous ceramic material is used for the substrate, then the atomization core can be manufactured, but the pore structure controllability and e-liquid guiding effect are poor
Solution Approach 1:
The patent changes the material parameters by transitioning from traditional porous ceramic to porous glass-ceramic, and specifically controls the tortuosity factor parameter within 1.0-2.5. This parameter optimization enables precise control over pore structure characteristics while improving e-liquid guiding performance and preventing liquid leakage.
2Reliability
If the tortuosity factor is not controlled, then the manufacturing process is simpler, but the e-liquid guiding efficiency decreases and liquid leakage occurs
Solution Approach 1:
The patent identifies and controls the tortuosity factor as a critical parameter, optimizing it to fall within 1.0-2.5. This parameter control achieves optimal balance between e-liquid guiding efficiency and manufacturing feasibility, preventing liquid leakage while maintaining practical manufacturability.
