Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If conventional topical delivery systems are used for CBD, then the formulation can be simple, but the viscosity stability and skin feel are insufficient
Solution Approach 1:
The patent employs composite material systems combining multiple rheology modifiers (clays, polymers, waxes) with CBD and emollients to achieve stable viscosity. The gelled delivery system uses a composite structure where organoclay particles form a network within the oil phase, providing rheological stability while maintaining aesthetic properties and skin feel.
2Quantity of substance
If high concentration of CBD is used, then the therapeutic effect is improved, but the formulation stability and skin feel deteriorate
Solution Approach 1:
The patent uses emollients and rheology modifiers as intermediary substances that facilitate the incorporation of high concentrations of CBD into the formulation. These intermediaries solubilize CBD and integrate it into the gelled structure, maintaining formulation stability and aesthetic properties even at high CBD loadings.
Solution Approach 2:
The patent adjusts physical parameters such as viscosity, gel structure, and phase composition to accommodate high CBD concentrations. By modifying the rheological properties through clay content, polymer selection, and wax composition, the formulation maintains stability and skin feel despite increased CBD content.
3Stability of the object's composition
If rheology modifiers are added to control viscosity, then the viscosity stability is improved, but the skin feel and application properties worsen
Solution Approach 1:
The patent applies local quality by using specific types of rheology modifiers (organoclays, polymers, waxes) that provide viscosity control in the bulk formulation while maintaining lightness and non-greasy feel at the skin interface. The composite approach allows different components to fulfill different functions: clays for structure, polymers for viscosity, and waxes for skin feel enhancement.
