Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing foaming devices are complex, costly, and difficult to clean due to separate heating and frothing components, often resulting in burnt milk residue at the bottom of the container, which complicates hygiene and cleaning.
Innovation Solution
A foaming device with a processing element that is mechanically decoupled from both the heating and driving units, allowing for inductive heating and magnetic field-driven movement within a container, enabling efficient foaming and heating while maintaining a simple and compact configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If separate heating element and whisk are used, then heating and foaming functions are achieved, but device complexity and cost increase
Solution Approach 1:
The patent combines the heating element and the whisk into a single integrated processing element. The heating element is positioned at the bottom of the whisk assembly, allowing both heating and foaming functions to be performed by one component rather than two separate elements, thereby reducing device complexity while maintaining functional versatility
Solution Approach 2:
The processing element is designed to perform multiple functions simultaneously: it acts as both a heating element (through the integrated heating component) and a whisk (through the rotating blades). This multi-functional design eliminates the need for separate heating and foaming components, simplifying the overall device structure
2Object-affected harmful factors
If heating element is placed at bottom of container, then heating function is achieved, but milk burns and adheres to container bottom
Solution Approach 1:
The heating element is extracted from the container bottom and integrated into the rotating whisk assembly. This removes the source of burning (stationary heating at container bottom) while preserving the heating function through the moving processing element that distributes heat more evenly and prevents milk adhesion
Solution Approach 2:
The heating element is transformed from a static component at the container bottom to a dynamic component integrated into the rotating whisk. The motion of the processing element during whisking distributes the heating action throughout the liquid, preventing localized overheating and milk burning at the container bottom
3Ease of operation
If thick film heater or induction heating is used, then heating function is achieved, but cleaning complexity increases due to burnt residue
Solution Approach 1:
The heating function is extracted from the container bottom and transferred to the removable processing element. This allows the container to be easily cleaned without burnt residue, while the heating function is maintained through the integrated heating element in the whisk assembly that can be removed or cleaned separately
4Reliability
If steam pipes or steam venturi nozzles are used, then frothing and heating are achieved, but premium quality fine and stable foam cannot be produced
Solution Approach 1:
The patent merges the heating element and the foaming mechanism (whisk blades) into a single integrated processing element. This combination allows simultaneous heating and foaming action, producing high-quality stable foam while avoiding the complexity of separate steam injection systems
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 effectively produces high-quality, hot foams with reduced heating time and enhanced cleanability by preventing milk from adhering to the container, as the processing element rotates and heats the fluid uniformly without direct mechanical contact, ensuring easy cleaning and improved hygiene.
Implementation Method 1
a driving unit and a distinct heating unit such that the processing element is mechanically decoupled from both the heating unit and the driving unit, the processing element being movable inside the container in response to a magnetic field generated by the driving unit
Implementation Method 2
the processing element further being inductively heatable by an oscillating magnetic field provided by the heating unit
Implementation Method 3
heats the fluid uniformly without direct mechanical contact
