Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If glass fiber material is used for liquid absorption, then liquid absorption capability is improved, but health safety deteriorates due to harmful effects on human body
Solution Approach 1:
The patent replaces glass fiber material with porous ceramic material for liquid absorption. The porous structure of the ceramic material provides effective liquid absorption capability while eliminating the health hazards associated with glass fiber materials.
Solution Approach 2:
The patent employs ceramic material as a composite alternative to traditional glass fiber material. This material substitution maintains the liquid absorption function while improving health safety by removing harmful components.
2Power
If heating wire directly contacts liquid storage component, then heating efficiency is improved, but liquid deterioration occurs due to direct heat transfer
Solution Approach 1:
The patent divides the heating system into separate components: the heating wire is wound around the atomizing rod rather than directly contacting the liquid storage component. This segmentation allows efficient heating of the atomizing rod while preventing direct heat transfer that would deteriorate the liquid in the storage component.
Solution Approach 2:
The atomizing rod serves as an intermediary between the heating wire and the liquid. The heating wire heats the atomizing rod, which then absorbs and vaporizes the liquid, preventing direct thermal contact between the heating wire and liquid storage component.
3Productivity
If liquid absorption rate is increased, then vaporization efficiency is improved, but liquid leakage increases
Solution Approach 1:
The porous ceramic material provides controlled liquid absorption through its pore structure. By adjusting the pore size and distribution, the material achieves optimal liquid uptake rate that ensures efficient vaporization while preventing excessive absorption that would lead to leakage.
Solution Approach 2:
The patent optimizes the physical parameters of the porous ceramic material, such as pore size, porosity, and surface area, to control the liquid absorption rate. These parameter adjustments enable balanced liquid management for efficient vaporization without leakage.
