Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the heating structure directly contacts the medicine liquid without an annular cavity, then the heating efficiency is high, but the atomized liquid infiltration is uneven and insufficient, leading to poor atomization quality
Solution Approach 1:
The patent introduces an annular cavity dimension between the heating structure and the ceramic part, transforming a direct contact one-dimensional interface into a three-dimensional space. This annular cavity allows atomized liquid to infiltrate from multiple directions (radially and axially), improving infiltration uniformity and atomization quality without significantly complicating the overall structure.
2Productivity
If the heating power is increased to improve atomization efficiency, then the vaporization speed increases, but local overheating occurs causing decomposition or chemical reactions
Solution Approach 1:
The patent employs a ceramic part with spatially varying porosity distribution, where different regions have different pore sizes and densities. This local quality variation enables differential heat distribution - regions with higher porosity allow better heat dissipation and liquid infiltration, preventing local overheating while maintaining high atomization efficiency in other regions.
Solution Approach 2:
The ceramic part acts as an intermediary between the heating structure and the atomized liquid. It mediates heat transfer by conducting heat uniformly while its porous structure allows liquid infiltration and evaporation, preventing direct overheating of the liquid and avoiding decomposition or chemical reactions.
3Manufacturing precision
If the ceramic part porosity is increased to improve liquid infiltration, then the atomization becomes more uniform, but the structural strength decreases
Solution Approach 1:
The ceramic part features spatially varying porosity where the outer wall has lower porosity for structural strength while the inner regions have higher porosity for liquid infiltration. This local quality differentiation allows the ceramic to maintain mechanical integrity while enabling uniform atomization through controlled liquid distribution.
