Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If ferulic acid is used in high concentration (≥1.9 wt.%) in water-containing compositions, then antioxidant and whitening benefits are improved, but odor problems occur after several days of storage
Solution Approach 1:
The patent removes water from the composition entirely, creating an anhydrous system. This extraction of the harmful component (water) prevents the chemical reactions that lead to ferulic acid degradation and odor formation, while preserving the beneficial high-concentration ferulic acid content (0.5-3.0 wt.%) for antioxidant and whitening effects
Solution Approach 2:
The patent creates an inert environment by using anhydrous conditions and selecting chemically stable polyol solvents (C3-C10 polyols) that do not react with ferulic acid. This inert environment prevents oxidation and degradation reactions, maintaining formulation stability and preventing odor development during storage
2Stability of the object's composition
If water-free cosmetic base is used to avoid water contact, then ferulic acid stability is improved, but oily/greasy sensory and heating sensation occur which limits skin care application
Solution Approach 1:
The patent changes the chemical parameters of the solvent system by selecting specific C3-C10 polyols with controlled chain lengths and molecular structures. These parameter adjustments modify the sensory properties of the anhydrous base, reducing greasiness and heating sensation while maintaining ferulic acid stability and solubility
Solution Approach 2:
The patent uses composite material strategies by combining ferulic acid with specific C3-C10 polyols and silica aerogel. This composite formulation achieves a balance between stability, sensory properties, and functionality, creating a product that is both stable and comfortable for skin application
3Stability of the object's composition
If low amount of ferulic acid is used in commercialized products, then stability is improved, but the product becomes too thin and flows easily making it inconvenient for consumer application
Solution Approach 1:
The patent changes the viscosity parameters of the formulation by selecting specific C3-C10 polyols and incorporating silica aerogel. These parameter modifications provide suitable thickness and spreadability for convenient application, while maintaining formulation stability and allowing higher ferulic acid content (0.5-3.0 wt.%) for enhanced efficacy
