Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a liquid guiding cotton string is wound around a heating wire, then the structure is simple, but the cross-sectional area for liquid conduction is small resulting in low vapor production and liquid leakage during high-temperature operation
Solution Approach 1:
The patent transitions from a linear cotton string (1D) to a sheet-like heating resistance with extended surface area (2D), and further to a three-dimensional porous ceramic body (3D). This dimensional expansion dramatically increases the liquid conduction cross-sectional area while maintaining structural simplicity, resolving the contradiction between simple structure and high vapor production.
2Device complexity
If a liquid guiding cotton string is wound around a heating wire, then the structure is simple, but the sealing between the vaporizing base and liquid guiding element is poor leading to liquid leakage
Solution Approach 1:
The patent employs a flexible sheet-like heating resistance that can conform to the vaporizing base surface, improving sealing performance. The soft liquid guiding element also provides flexible contact sealing, preventing liquid leakage while maintaining structural simplicity.
3Quantity of substance
If a heating resistance is disposed on the bottom of a porous ceramic body, then the liquid conduction area is increased, but macromolecules and micro-particles accumulate and gum up the micro-pores resulting in reduced vapor amount, inconsistent tastes, and burned taste
Solution Approach 1:
The patent changes the pore size parameter of the ceramic body from micro-pores to macro-pores or large micro-pores. This parameter change prevents accumulation of macromolecules and micro-particles, eliminating gumming and charring issues while maintaining adequate liquid conduction area for consistent operation.
4Quantity of substance
If a porous ceramic body is used, then the liquid conduction area is increased, but the manufacturing process becomes complicated, cost increases, and production efficiency decreases
Solution Approach 1:
The patent adopts a sheet-like heating resistance that can be easily manufactured and replaced, eliminating the need for complex porous ceramic body manufacturing processes. This approach maintains adequate liquid conduction area while dramatically simplifying production and improving efficiency.
5Quantity of substance
If a porous ceramic body with complex compositions is used, then the liquid conduction area is increased, but heavy metal precipitation occurs after long period of high-temperature operation
Solution Approach 1:
The patent extracts and removes the problematic porous ceramic body component entirely, replacing it with a sheet-like heating resistance and soft liquid guiding element. This extraction eliminates the source of heavy metal precipitation while maintaining the necessary liquid conduction area through alternative structural designs.
