Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a filter-type milk frothing head with complex structure is used, then fine milk foam can be produced, but milk residues accumulate in the interior making it difficult to clean
Solution Approach 1:
The milk frothing head is divided into detachable components including a first frothing frame, second frothing frame, and removable filter screen. This segmentation allows each component to be easily separated for cleaning, eliminating the cleaning difficulty associated with integrated complex structures while maintaining the fine milk foam production capability.
Solution Approach 2:
The filter screen is extracted as a separate removable component from the frothing head structure. This allows the filter screen to be easily taken out for cleaning independently, solving the problem of milk residue accumulation in hard-to-reach areas while preserving the milk foam quality function.
2Productivity
If an impeller structure is used in the milk frothing head, then milk can be stirred effectively, but excessive air intake occurs
Solution Approach 1:
The impeller structure is completely removed from the milk frothing head design. Instead of using mechanical stirring with an impeller, the invention uses a filter screen-based system that achieves milk frothing through the interaction of milk flow with the filter screen pores, thereby eliminating excessive air intake while maintaining stirring efficiency.
Solution Approach 2:
The mechanical impeller stirring system is replaced with a passive filter screen-based frothing mechanism. The milk flow itself interacts with the filter screen to create foam, substituting active mechanical stirring with a flow-based passive frothing process that prevents excessive air intake.
3Ease of operation
If a simple milk frothing head structure is used, then it is easy to clean, but fine milk foam cannot be produced
Solution Approach 1:
The filter screen is designed with specific local characteristics including particular pore sizes, materials (stainless steel), and configurations (ring shape with specific inner diameters). These localized quality features enable fine milk foam production at the filter screen level while the overall structure remains simple and easy to clean through detachable components.
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 design produces delicate and dense milk foam efficiently while being easy to clean and maintain, reducing the risk of excessive air intake and improving user experience.
Implementation Method 1
when the milk frothing head rotates, bubbles are divided into small bubbles by the at least one filter screen, and the small bubbles form delicate and dense milk foam with milk
Implementation Method 2
A connecting rod configured to connect to an external power device is disposed on one end of the first frothing frame
Implementation Method 3
a shock absorber configured to reduce vibration of the transmission shaft is mounted in the transmission shaft

AI summary
A milk frothing head and a frother are provided. The milk frothing head includes a first frothing frame and a second frothing frames detachably connected to the first frothing frame. A connecting rod configured to connect to an external power device is disposed on the first frothing frame. At least one filter screen of a ring shape is mounted between the first frothing frame and the second frothing frame. A head end of the at least one filter screen is connected to a tail end of the at least one filter screen. The first frothing frame defines a first through hole. The second frothing frame defines a second through hole corresponding to the first through hole. When the milk frothing head rotates, bubbles are divided into small bubbles by the at least one filter screen, and the small bubbles form delicate and dense milk foam with milk.
