Milk Frothing and Heating Apparatus with Centered Stirring and Heating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing milk frothing apparatuses with heating functions suffer from low heat transfer efficiency and frothing efficiency due to the stirring and heating components being offset from the center, leading to complex cleaning and reduced usability.
Innovation Solution
A milk frothing and heating apparatus with a centered stirring assembly and heating assembly integrated into a lid body, where the stirring rod and heating portion extend into the milk jar's center, driven by a motor within the lid, enhancing both frothing and heating efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a heating rod is provided at the bottom of the lid body, then the apparatus gains heating function, but the stirring apparatus must deviate from the center which affects frothing efficiency
Solution Approach 1:
The heating assembly is positioned at the bottom of the lid body rather than the side, allowing it to extend downward into the milk jar without interfering with the central stirring position. This spatial reconfiguration in the vertical dimension resolves the conflict between adding heating functionality and maintaining central stirring alignment for optimal frothing efficiency.
2Adaptability or versatility
If the stirring assembly and heating assembly are both provided in the lid body, then both functions are integrated, but the structure becomes complex and cleaning becomes troublesome
Solution Approach 1:
The lid body is divided into an upper lid and a lower lid that can be separated from each other. The stirring assembly is connected to the lower lid while the heating assembly is fixed to the bottom surface of the lower lid. This segmentation allows both assemblies to be easily removed from the milk jar by simply detaching the lower lid, significantly simplifying the cleaning process despite the integrated functionality.
3Ease of manufacture
If only one side of the stirring rod is provided with the heating rod, then the structure is simple, but the heat transfer efficiency is low
Solution Approach 1:
The heating assembly is designed with a heating portion that extends downward from the bottom of the lid body to contact the milk at the bottom of the jar. This creates a localized high-efficiency heat transfer zone at the bottom of the milk jar where direct contact between the heating portion and milk occurs, significantly improving heat transfer efficiency compared to heating from the side only.
