Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional polyvinyl chloride floor is used, then it provides basic flooring functionality, but it is prone to staining, not resistant to chemicals like iodine, and difficult to maintain
Solution Approach 1:
The patent applies composite materials by combining polyvinyl chloride base layer with a fluorine-containing polymer coating layer. The fluorine-containing polymer (such as PTFE or PVDF) provides exceptional stain resistance and chemical resistance properties that the conventional polyvinyl chloride floor lacks, while maintaining ease of cleaning through its non-stick surface characteristics.
Solution Approach 2:
The patent changes the surface chemical composition parameter by introducing fluorine-containing polymers with specific fluorine content (20-40% by weight). This parameter change transforms the surface properties to achieve high stain resistance and chemical resistance while maintaining the original flooring functionality.
2Adaptability or versatility
If a conventional polyvinyl chloride floor is used, then it provides basic flooring functionality, but it releases organic volatile gases and has limited application range
Solution Approach 1:
The fluorine-containing polymer coating creates an inert, chemically stable surface environment that resists chemical reactions with stains and pollutants. This inert surface layer prevents harmful interactions between the floor and environmental contaminants, reducing the release of organic volatile gases and expanding safe application ranges to include hospitals, schools, and food processing facilities.
3Reliability
If a fluorine-containing polymer coating is added to enhance stain resistance, then chemical resistance and wear resistance improve, but the structural complexity increases
Solution Approach 1:
The patent segments the flooring structure into two functional layers: a polyvinyl chloride base layer providing structural support and a fluorine-containing polymer coating layer providing surface protection. This segmentation allows each layer to be optimized for its specific function while maintaining overall system simplicity through a straightforward two-layer architecture.
