Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If integrated molding technology is used to prepare liquid storage cotton with uniform density, then the manufacturing process is simple and structure is uniform, but the atomization liquid transportation efficiency is low and utilization rate is not ideal
Solution Approach 1:
The patent applies local quality by creating different density regions within the liquid storage cotton. The first liquid storage layer has a first density while the second liquid storage layer has a second density different from the first density. This allows different regions to have different capillary forces optimized for their specific functions - the lower density region for better liquid retention and the higher density region for faster transportation, thereby resolving the contradiction between manufacturing simplicity and transportation efficiency.
2Volume of stationary object
If atomization liquid is transported through long paths in liquid storage cotton, then the storage capacity is increased, but the transportation efficiency decreases and residual liquid increases
Solution Approach 1:
The patent changes the density parameter of the liquid storage cotton in different regions. By having the first liquid storage layer with a first density and the second liquid storage layer with a second density, the capillary force parameter is optimized for different zones. This allows the system to maintain large storage capacity while improving transportation efficiency through strategically optimized density distribution that reduces residual liquid.
