Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Static emulsifiers result in low yield of emulsified solution and scale formation due to lack of shearing forces, while dynamic emulsifiers with heavy rotary disks consume excessive energy.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a dynamic emulsifier with blades mounted on a rotary disk is used, then emulsification yield is improved, but energy consumption increases drastically
Solution Approach 1:
The rotary disk is designed with multiple through-holes penetrating its thickness, transforming it from a solid heavy structure to a porous lightweight structure. This reduces the moment of inertia and weight of the rotary disk, thereby significantly reducing the energy required for rotation while maintaining the shearing action necessary for emulsification
Solution Approach 2:
The rotary disk is segmented into multiple sections with through-holes distributed across its surface. This segmentation approach reduces material usage and weight while maintaining structural integrity and functional effectiveness in generating shearing forces for emulsification
2Productivity
If a heavy rotary disk is used to generate shearing forces, then emulsification efficiency is improved, but energy consumption increases
Solution Approach 1:
The rotary disk incorporates multiple through-holes that create a porous structure, reducing its weight and moment of inertia. This allows the disk to rotate more easily and generate the necessary shearing forces with less energy input, resolving the contradiction between emulsification efficiency and energy consumption
3Use of energy by moving object
If static emulsifiers are used, then energy consumption is reduced, but scale formation occurs and yield decreases
Solution Approach 1:
The invention transitions from a static emulsifier to a dynamic system where a rotary disk rotates to generate shearing forces. The rotary disk with through-holes creates dynamic fluid motion and turbulence that prevents scale formation on the emulsification element surface, thereby improving emulsification yield while maintaining relatively low energy consumption due to the lightweight design
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device achieves improved emulsification with reduced energy consumption and increased yield by generating enhanced shearing forces and turbulent flow, facilitating better mixing and dissolution rates.
Implementation Method 1
The shearing forces created when the two liquid phases are stirred facilitate the detachment of the droplets at the liquid-liquid interface from the emulsification element
Implementation Method 2
the turbulent flow generated during stirring can also accelerate the two-phase compatibility
Implementation Method 3
When the two liquid phases come into contact in an emulsification element in a static emulsifier, the droplets formed in the dispersed phase spontaneously detach
