Engineering Contradiction Analysis
1Power
If beauty devices are used to generate microcurrents, then microcurrent generation capability is improved, but device complexity and ease of operation deteriorate
Solution Approach 1:
The patent replaces mechanical beauty devices that generate microcurrents with a chemical system. The liquid crystal nanoemulsion contains electrolytes and liquid crystal molecules that generate microcurrents through chemical reactions and piezoelectric effects when applied to the skin, eliminating the need for complex mechanical devices while maintaining microcurrent generation capability
Solution Approach 2:
The patent changes the physical and chemical parameters of the cosmetic formulation by incorporating liquid crystal nanoemulsion with specific electrical conductivity ranges (10-1000 μS/cm) and controlled piezoelectric properties. These parameter changes enable the cosmetic itself to generate microcurrents without requiring external power sources or complex device infrastructure
2Power
If pressure is applied during cosmetic application to generate microcurrents, then microcurrent generation is improved, but ease of operation deteriorates
Solution Approach 1:
The liquid crystal nanoemulsion is designed to generate microcurrents through its inherent piezoelectric properties when subjected to normal application movements. The system serves itself by converting the mechanical energy of simple rubbing or massaging motions into electrical energy, eliminating the need for complex application procedures or additional energy input from the user
Solution Approach 2:
The patent utilizes the dynamic piezoelectric properties of liquid crystal molecules that respond to mechanical stress during application. The liquid crystal phase transition and molecular reorientation under applied pressure generate electrical charges, allowing the cosmetic to actively generate microcurrents during normal, gentle application without requiring excessive force or complex manipulation
3Power
If electrical conductivity is increased in the nanoemulsion, then microcurrent generation is improved, but manufacturing precision deteriorates
Solution Approach 1:
The patent employs composite material formulation by combining liquid crystal molecules with electrolytes in a nanoemulsion system. This composite structure allows the formulation to achieve target electrical conductivity ranges (10-1000 μS/cm) through the synergistic interaction of components, providing buffering capacity that tolerates normal manufacturing variations while maintaining functional performance
Solution Approach 2:
The patent achieves controlled electrical conductivity through parameter optimization of the liquid crystal nanoemulsion formulation, including concentration of electrolytes, type of liquid crystal molecules, and emulsion structure. These parameter changes enable the system to maintain stable electrical properties within acceptable ranges despite normal manufacturing variations, balancing functionality with manufacturability
