Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a conventional atomization core is used with capillary action for e-liquid transport, then the device structure is simple, but dry heating and oil leakage occur leading to harmful substance production
Solution Approach 1:
The patent changes the permeation rate parameter of the porous ceramic substrate to a specific range (0.03-0.08 mL/min.bar.mm2) to optimize e-liquid transport. This parameter optimization prevents both dry heating (insufficient e-liquid supply) and oil leakage (excessive e-liquid supply), thereby eliminating harmful substance production while maintaining atomization stability.
Solution Approach 2:
The patent uses a porous ceramic substrate as a composite material that combines capillary action for e-liquid transport with controlled permeation characteristics. The ceramic material provides both the structural support and the regulated fluid transport mechanism, preventing harmful substance formation through its unique porous structure and controlled permeability.
2Reliability
If the permeation rate of porous ceramic substrate is increased to prevent dry heating, then e-liquid supply is improved, but oil leakage occurs
Solution Approach 1:
The patent optimizes the permeation rate parameter to a precise range (0.03-0.08 mL/min.bar.mm2) that balances e-liquid supply needs with prevention of oil leakage. This controlled parameter range ensures sufficient e-liquid reaches the heating element for reliable atomization while preventing excessive flow that would cause oil leakage and harmful substance generation.
3Object-generated harmful factors
If the permeation rate of porous ceramic substrate is decreased to prevent oil leakage, then e-liquid control is improved, but dry heating occurs
Solution Approach 1:
The patent sets the permeation rate parameter within the optimal range (0.03-0.08 mL/min.bar.mm2) to prevent both oil leakage and dry heating. This carefully controlled parameter ensures that sufficient e-liquid flows through the ceramic substrate to maintain continuous atomization, preventing dry heating and harmful substance formation while the controlled permeability prevents oil leakage.
