Solution Overview
Problem
Current emulsification processes are inefficient and costly, requiring complex mechanical equipment and resulting in unstable emulsions with limited storage stability, especially when producing emulsions with solid particles or liposomes, which are difficult to scale up and maintain over time.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If mechanical emulsification processes (rotor-stator, ultrasound, high-pressure systems) are used to create fine emulsions, then droplet size is reduced and emulsion is formed, but device complexity increases and storage stability remains limited
Solution Approach 1:
The patent replaces complex mechanical emulsification systems (rotor-stator, ultrasound, high-pressure homogenizers) with a magnetic field-based system. Immiscible liquids are circulated through a magnetic field generator that creates alternating magnetic fields, inducing eddy currents and electromagnetic forces that disrupt droplets and form stable emulsions without mechanical contact, thereby reducing device complexity while achieving fine droplet sizes.
Solution Approach 2:
The patent changes the physical state and properties of the emulsion by applying magnetic fields with specific parameters (frequency, intensity, duration). By adjusting magnetic field parameters rather than mechanical parameters, the system achieves controlled droplet formation and improved storage stability without the complexity of mechanical equipment.
2Manufacturing precision
If mechanical energy is supplied to break up large drops and form fine emulsions, then droplet disruption is achieved, but energy consumption increases and storage stability is not sufficiently improved
Solution Approach 1:
The patent substitutes mechanical energy input with electromagnetic energy. Instead of using high-shear mixers, ultrasonic processors, or high-pressure pumps that consume significant mechanical energy, the system uses a magnetic field generator to create electromagnetic forces that disrupt droplets and form emulsions with lower overall energy consumption while achieving comparable or superior droplet sizes and storage stability.
3Stability of the object's composition
If emulsifiers and stabilizers are added to prevent phase separation and improve storage stability, then storage stability is improved, but manufacturing cost increases and process complexity increases
Solution Approach 1:
The patent replaces chemical stabilization methods (adding emulsifiers and stabilizers) with a physical method using magnetic fields. The alternating magnetic field induces electromagnetic forces and eddy currents that continuously act on the droplets, preventing coalescence and phase separation without requiring additional chemical additives, thereby improving storage stability while reducing process complexity and manufacturing costs.
Solution Approach 2:
The magnetic field acts as an intermediary physical field that mediates between the immiscible liquid phases. Instead of using chemical emulsifiers to bridge the interface between phases, the magnetic field provides a physical mechanism for droplet disruption and stabilization, eliminating the need for additional chemical substances and simplifying the overall process.
4Quantity of substance
If mechanical emulsification equipment is used to produce emulsions with solid particles or liposomes, then emulsion is formed, but equipment clogging occurs and scalability is limited
Solution Approach 1:
The patent replaces mechanical emulsification equipment with a magnetic field-based system that has no moving parts or narrow passages that could clog. The magnetic field generator creates electromagnetic forces that act on the entire volume of the emulsion, allowing solid particles and liposomes to be evenly distributed without mechanical contact, thereby eliminating clogging issues and simplifying equipment maintenance while maintaining production capacity and scalability.
