Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If current organosilicone technologies are used in consumer products, then benefits such as softness, hair conditioning, and color protection are achieved, but the products become expensive and suffer from chemical and physical instability manifesting as creaming and discoloration
Solution Approach 1:
The patent changes the chemical parameters of the silicone polymer by modifying the terminal groups from conventional structures to primary amino groups, and by controlling the molecular weight and composition ratios during synthesis. These parameter changes result in improved chemical and physical stability while reducing the need for expensive emulsification steps, thereby addressing both reliability and manufacturing cost concerns
2Reliability
If terminal primary aminosilicone polymers are used to produce polysiloxane copolymers, then economical and stable products can be obtained, but conventional wisdom suggests this approach cannot be used
Solution Approach 1:
The patent applies preliminary action by pre-selecting and optimizing the specific reactants and processing conditions before the actual polymerization process. The method predeterminedly establishes the correct molar ratios, temperature ranges, and reaction sequences that will yield stable polysiloxane copolymers with primary amino terminal groups, thereby simplifying the overall process while ensuring product reliability
