Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If conventional crosslinked organopolysiloxane and amorphous silicic anhydride are used, then the cosmetic provides some matte texture, but the matte texture quality and stability are insufficient
Solution Approach 1:
The patent changes the chemical parameters by introducing a crosslinked organopolysiloxane with specific structural characteristics (partially crosslinked structure with controlled crosslinking degree) and combines it with amorphous silicic anhydride in specific proportions. This parameter optimization resolves the contradiction by achieving both improved matte texture quality and enhanced cosmetic stability through precise compositional control.
Solution Approach 2:
The patent creates a composite material system by combining crosslinked organopolysiloxane, amorphous silicic anhydride, and other cosmetic ingredients in specific ratios. This composite approach resolves the technical contradiction by synergistically combining the matte-forming properties of silicic anhydride with the stabilizing and texture-enhancing properties of crosslinked organopolysiloxane, achieving both high matte texture quality and product stability.
2Reliability
If the cosmetic formulation is optimized for matte texture, then the texture quality improves, but the stability and resistance to oil separation worsen
Solution Approach 1:
The patent optimizes the crosslinking degree of the organopolysiloxane and the proportion of amorphous silicic anhydride to achieve a balance where the matte texture quality is maximized while the formulation maintains adequate stability. The specific parameter ranges disclosed ensure that the cosmetic resists oil separation while providing the desired matte finish.
Solution Approach 2:
The crosslinked organopolysiloxane acts as an intermediary substance that bridges the matte-forming silicic anhydride and the oil phase. This intermediary component ensures proper distribution and stabilization of the silicic anhydride particles, preventing oil separation while maintaining the matte texture effect.
