Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If current organosilicone technologies are used in consumer products, then benefits such as softness and conditioning are achieved, but the products become expensive and suffer from poor chemical and physical stability leading to creaming and discoloration
Solution Approach 1:
The patent changes the chemical parameters of the silicone formulation by using specific polysiloxane copolymers with controlled molecular weights and compositions. This transforms the unstable current organosilicones into stable polysiloxane copolymers that resist creaming and discoloration, while the parametric control of the formulation enables cost-effective manufacturing without requiring expensive emulsification steps
Solution Approach 2:
The invention creates composite polysiloxane copolymer structures combining different siloxane units with specific properties. These composite materials integrate the beneficial conditioning effects of silicones with enhanced stability characteristics, achieving a material that simultaneously provides consumer product benefits while eliminating the instability and high cost issues of current organosilicones
2Reliability
If current silicone technologies are used, then conditioning benefits are provided, but creaming and discoloration occur in the product and on treated surfaces
Solution Approach 1:
The patent converts the inherently unstable nature of current organosilicones into a benefit by carefully controlling the polymerization process to create polysiloxane copolymers with predetermined stability characteristics. The formulation process transforms potential instability into enhanced stability, preventing creaming and discoloration while maintaining the conditioning benefits
Solution Approach 2:
By changing the molecular parameters of the silicone formulation - specifically using polysiloxane copolymers with controlled molecular weights and compositions - the patent eliminates creaming and discoloration. The parametric control of the copolymer structure ensures that the product maintains stability on treated surfaces while providing ongoing conditioning benefits
3Ease of manufacture
If terminal primary aminosilicone polymers are used as reactants, then polysiloxane copolymers can be produced, but the process may be expensive due to raw material and emulsification costs
Solution Approach 1:
The patent extracts and eliminates the expensive emulsification step from the manufacturing process. By formulating polysiloxane copolymers that are inherently stable and compatible with consumer product systems, the invention removes the need for costly emulsifiers and complex emulsification procedures, achieving cost-effective manufacturing without sacrificing chemical stability
Solution Approach 2:
The invention replaces expensive current organosilicone raw materials with more economical polysiloxane copolymer alternatives. By using terminal primary aminosilicone polymers as reactants to create these copolymers, the patent achieves lower raw material costs while maintaining or improving chemical stability, making the overall manufacturing process more economical
