Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If ceramides are incorporated into cosmetic preparations, then skin barrier function is improved, but compatibility with other compounds deteriorates
Solution Approach 1:
The patent changes the chemical structure parameters of ceramide by introducing a polymerizable group (vinyl group) at the sn-1 position of the ceramide molecule. This structural modification allows ceramide to undergo polymerization while retaining its essential barrier function, thereby improving compatibility with other cosmetic compounds through the resulting polymer's enhanced adaptability.
Solution Approach 2:
The patent creates a composite material by polymerizing modified ceramide molecules to form a polymeric structure. This composite approach combines the barrier function of ceramide with the versatility of polymer materials, enabling the substance to function effectively in diverse cosmetic formulations while maintaining skin barrier protection.
2Reliability
If ceramides are incorporated into cosmetic preparations, then skin barrier function is improved, but ease of manufacture deteriorates
Solution Approach 1:
The patent modifies the physical and chemical parameters of ceramide by adding a polymerizable vinyl group, which enables the substance to be incorporated into cosmetic preparations through polymerization processes. This parameter change transforms ceramide from a difficult-to-incorporate ingredient into a versatile component that can be easily manufactured and formulated.
Solution Approach 2:
The patent creates a copy or derivative of natural ceramide by introducing a synthetic vinyl group at the sn-1 position. This modified ceramide analog maintains the essential barrier function of natural ceramide while gaining the manufacturing advantages of synthetic polymers, making it easier to produce and incorporate into cosmetic products.
3Reliability
If ceramides are incorporated into cosmetic preparations, then skin barrier function is improved, but texture quality deteriorates
Solution Approach 1:
The patent changes the molecular parameters of ceramide by introducing a polymerizable group and subsequently polymerizing it. This transformation alters the physical properties of ceramide, resulting in a polymeric form that provides excellent texture quality in cosmetic preparations while maintaining the skin barrier function.
4Reliability
If ceramides are incorporated at high concentrations, then skin barrier function is improved, but compatibility with other compounds deteriorates
Solution Approach 1:
The patent creates a polymeric composite material from modified ceramide that can be incorporated at high concentrations. The polymeric structure provides a matrix that maintains compatibility with other cosmetic compounds even at high ceramide concentrations, enabling effective barrier function without formulation conflicts.
