Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If ceramide-containing compositions are formulated with conventional ingredients, then basic skin barrier function is achieved, but storage stability and viscosity consistency deteriorate over time
Solution Approach 1:
The patent applies composite materials by formulating a specific combination of ceramide (0.1-10 wt%), cholesterol (0.1-5 wt%), and polyglycerol carboxylic acid ester (0.1-5 wt%) together with optional skin-conditioning agents. This composite formulation creates a synergistic system where the interaction between these specific components maintains both storage stability and viscosity consistency over extended periods, resolving the contradiction between basic functionality and long-term compositional stability.
2Reliability
If ceramide compositions are designed for basic barrier function, then skin protection is provided, but tolerance to freeze-thaw cycles is limited
Solution Approach 1:
The patent employs parameter changes by optimizing the concentration ranges of key components: ceramide (0.1-10 wt%), cholesterol (0.1-5 wt%), and polyglycerol carboxylic acid ester (0.1-5 wt%). This specific parameter optimization enables the formulation to maintain its structural integrity and viscosity through multiple freeze-thaw cycles, significantly improving reliability under temperature stress while preserving compositional stability.
3Ease of operation
If individual ceramide components are used, then skin barrier support is provided, but sensory properties and skin feel are suboptimal
Solution Approach 1:
The patent merges multiple components into a unified formulation system combining ceramide, cholesterol, and polyglycerol carboxylic acid ester, along with optional skin-conditioning agents. This merging creates synergistic effects that enhance sensory properties and skin feel beyond what individual ceramide components can achieve alone, while maintaining compositional stability through the balanced interaction of all ingredients.
4Productivity
If conventional ceramide formulations are used, then basic cosmetic properties are achieved, but hair growth stimulation is limited
Solution Approach 1:
The patent applies universality by designing a multi-functional formulation that simultaneously provides skin barrier support, sensory improvement, and hair growth stimulation. The core combination of ceramide, cholesterol, and polyglycerol carboxylic acid ester creates a versatile system that can address multiple cosmetic concerns in a single application, reducing the need for separate products while managing formulation complexity through a streamlined ingredient approach.
