Agitation Blade Geometry for Fine Foaming Green Tea
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing beverage preparation apparatuses are not optimal for agitating fine particles of green tea, and they do not effectively achieve fine foaming simultaneously with agitation.
Innovation Solution
An agitation blade with a central axis of rotation and multiple blade portions surrounding it, designed to rotate within an agitation tank, featuring a slit at the tip end and an auxiliary blade portion, which creates a vortex flow for efficient foaming and agitation, along with a contactless rotational drive mechanism and a rectifying wall to manage the flow of liquids and powders.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If conventional agitation means is used, then agitation of liquid is achieved, but fine foaming is not effectively realized
Solution Approach 1:
The agitation blade is divided into multiple blade portions (first blade portion and second blade portion) arranged radially around the rotation axis. This segmentation allows different portions to perform different functions: the first blade portion creates vertical flow for agitation, while the second blade portion generates horizontal flow for foaming, thereby achieving both agitation efficiency and fine foaming simultaneously
Solution Approach 2:
The invention introduces a radial dimension to the blade structure by arranging blade portions at different radial positions. The first blade portion is positioned closer to the center for vertical agitation, while the second blade portion is positioned farther out for horizontal foaming action. This dimensional arrangement enables simultaneous multi-functional operation without compromising either agitation or foaming performance
2Quantity of substance
If steam is used for foaming milk, then foaming is achieved, but skillful operation is required
Solution Approach 1:
The agitation blade automatically generates fine foam through its rotating blade portions that agitate the liquid and incorporate air. This self-service mechanism eliminates the need for skilled manual steam foaming operations, as the blade structure itself performs the foaming function through its geometric design and rotational motion, making the process accessible to users without specialized skills
3Quantity of substance
If conventional agitation blade design is used, then simple structure is maintained, but fine foaming capability is insufficient
Solution Approach 1:
The agitation blade is designed with multiple blade portions that simultaneously perform multiple functions: agitation, aeration, and foaming. By integrating these functions into a single blade structure rather than requiring separate components, the invention achieves fine foaming capability without proportionally increasing overall device complexity
Solution Approach 2:
The blade portions are designed with specific geometric parameters including inclination angles, radial positions, and dimensions that optimize both agitation and foaming performance. By carefully controlling these parameters, the invention achieves effective fine foaming with a relatively simple blade structure that does not require complex mechanisms
