Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the liquid guiding component is made with high porosity material to improve liquid guiding capability, then liquid transmission is enhanced, but thermal conduction capability deteriorates
Solution Approach 1:
The atomizer is divided into distinct functional regions: a liquid guiding portion with higher porosity for optimal liquid transmission, and an atomizing portion with lower porosity for better thermal conduction. This segmentation allows each region to be optimized for its specific function without compromising the other.
Solution Approach 2:
Different porosity values are assigned to different parts of the atomizer. The liquid guiding portion has a first porosity value optimized for liquid flow, while the atomizing portion has a second porosity value optimized for heat conduction. This local differentiation of material properties resolves the contradiction between liquid guiding and thermal conduction requirements.
2Loss of energy
If the atomizing component uses low porosity material to improve thermal conduction, then heating efficiency is enhanced, but liquid infiltration capability deteriorates
Solution Approach 1:
The atomizer structure is segmented into a liquid guiding portion and an atomizing portion, each with optimized porosity for its specific function. The liquid guiding portion maintains high porosity for liquid infiltration, while the atomizing portion uses lower porosity for thermal conduction, eliminating the need for compromise.
Solution Approach 2:
The porosity property is locally optimized: the liquid guiding portion has higher porosity to facilitate liquid infiltration, while the atomizing portion has lower porosity to enhance thermal conduction. This spatial variation in material properties allows both requirements to be satisfied simultaneously.
3Adaptability or versatility
If the atomizer structure is expanded to accommodate separate liquid guiding and atomizing components with different properties, then functional optimization is improved, but device complexity and space occupation increase
Solution Approach 1:
The liquid guiding portion and atomizing portion are merged into a single integrated atomizer structure, eliminating the need for separate components. This integration maintains the functional optimization of differentiated porosity while reducing overall device complexity and space occupation.
Solution Approach 2:
The integrated atomizer structure performs multiple functions: the liquid guiding portion handles liquid transmission while the atomizing portion performs heating and atomization. This multi-functional design achieves functional optimization without increasing device complexity, as both functions are embedded within a single unified structure.
