Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If silicone-containing film forming agents with low glass transition temperatures are used, then wear resistance and transfer resistance are improved, but application properties and feel upon application deteriorate
Solution Approach 1:
The composition is divided into two immiscible components: Component A containing silicone-containing film forming agents with low glass transition temperatures for wear resistance, and Component B containing phenylated silicones for improved application properties and feel. This segmentation allows each component to independently contribute its beneficial properties without interfering with the other.
Solution Approach 2:
The invention creates a composite cosmetic composition by combining two immiscible components with different functional properties. Component A provides the film-forming and wear-resistant properties, while Component B provides the sensory and application properties, resulting in a composite material that exhibits both long-wear performance and good application characteristics.
2Duration of action of stationary object
If long-wearing and transfer-resistant properties are achieved, then durability is improved, but application properties and feel upon application worsen
Solution Approach 1:

This segmentation allows each component to independently contribute its beneficial properties without interfering with the other.
Solution Approach 2:

Component A provides the film-forming and wear-resistant properties, while Component B provides the sensory and application properties, resulting in a composite material that exhibits both long-wear performance and good application characteristics.
3Ease of operation
If a single-step composition is used, then application simplicity is improved, but achieving stable formulation with multiple properties becomes difficult
Solution Approach 1:
The invention utilizes changes in physical parameters, specifically the glass transition temperature of the silicone-containing film forming agents (lower than normal human body temperature), to achieve phase separation upon application. This parameter change allows the immiscible components to separate into distinct layers on the skin, providing different functional properties in a single-step application.
Solution Approach 2:
The invention exploits phase transition phenomena where the immiscible Component A and Component B separate into distinct phases upon application to the skin. The low glass transition temperature of Component A allows it to remain flexible and form a stable film on the skin, while Component B provides a separate phase for sensory properties, achieving formulation stability with multiple properties in a single step.
