Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If conventional essential oil absorption layer is used, then the sheet can evaporate anti-mildew essential oil, but the storage capacity is low and evaporation is rapid leading to frequent replacement
Solution Approach 1:
The patent introduces a non-level oil absorption film with three-dimensional housing spaces that rise from the oil absorption film surface. This vertical dimensionality allows the sheet to store significantly more anti-mildew essential oil within the same footprint, directly increasing storage capacity while extending lifespan by reducing replacement frequency
Solution Approach 2:
The housing spaces are nested within the structure of the non-level oil absorption film, with the second oil absorption layer surrounding and containing these spaces. This nested configuration maximizes the use of available space within the sheet structure, allowing multiple functional layers to coexist and work together to enhance storage capacity
2Quantity of substance
If the essential oil absorption layer is made with single-layer structure, then the manufacturing is simple, but the storage capacity and evaporation efficiency are insufficient
Solution Approach 1:
The oil absorption film is segmented into multiple functional layers: a first oil absorption layer in contact with the high-fiber substrate, an impermeable polyester layer, and a second oil absorption layer with housing spaces. This segmentation allows each layer to perform specific functions - absorption, containment, and enhanced evaporation - thereby increasing overall storage capacity and evaporation efficiency while maintaining manageable manufacturing complexity through modular layer assembly

a first oil absorption layer to absorb anti-mildew essential oil
Implementation Method 2
a second oil absorption layer to absorb the anti-mildew essential oil
Implementation Method 3
the housing spaces formed between the non-level polyester layer and second oil absorption layer can store more anti-mildew essential oil and increase evaporation speed thereof

AI summary
A non-level multilayer antibacterial sheet comprises a high-fiber substrate, at least one oil absorption film located on the high-fiber substrate and a non-level oil absorption film located at one side of the oil absorption film remote from the high-fiber substrate. The oil absorption film can absorb anti-mildew essential oil. The non-level oil absorption film includes a non-level polyester layer and a second oil absorption layer. The non-level polyester layer and second oil absorption layer form a plurality of housing spaces between them to store the anti-mildew essential oil. Through the oil absorption film and non-level oil absorption film, total amount of absorbed essential oil can be increased to lengthen lifespan of the antibacterial sheet. The housing spaces can store more essential oil and also accelerate evaporation thereof. Thus the anti-mildew essential oil can be dispersed more efficiently to enhance mildew proof effect.
