Tea drinking vacuum flask with tea-making function
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable vacuum flasks used for tea-making often retain tea water at the top due to vacuum formation, leading to scalding when opened, as the liquid is blocked by vacuum and water surface tension, affecting tea leaf and water separation.
Innovation Solution
The design incorporates a filtering element with open slots and filtering holes, where the flow area of the open slots is significantly larger than the filtering holes, allowing air to flow and preventing vacuum formation, enabling smooth tea water flow and effective separation of tea leaves and water.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a filter is arranged inside the vacuum flask body for storing tea leaves and separating tea water, then tea leaf and water separation is improved, but vacuum formation blocks tea water flow causing retention in the lid body
Solution Approach 1:
The filter is divided into two functional parts: a filtering element with filtering holes for tea leaf separation, and an air flow guiding structure with open slots for vacuum prevention. This segmentation allows each part to perform its specific function independently - the filtering holes separate tea leaves while the open slots manage air flow to prevent vacuum formation that would block water flow.
Solution Approach 2:
The air flow guiding structure acts as an intermediary between the filtering element and the lid body. It introduces air flow paths (open slots) that mediate the pressure differential, preventing vacuum formation while allowing the filtering element to maintain its separation function. This intermediary structure resolves the conflict between filtration and fluid flow.
2Loss of energy
If the vacuum flask maintains a vacuum state for insulation, then thermal insulation is improved, but vacuum formation prevents tea water from flowing down into the liquid containing body
Solution Approach 1:
The air flow guiding structure is strategically positioned at specific locations (such as the connection between lid body and connecting piece) where vacuum formation most effectively blocks water flow. By localizing the air flow paths in these critical areas, the patent prevents vacuum-induced flow blockage without compromising the overall vacuum insulation performance of the flask body.
Solution Approach 2:
The open slots provide sufficient air flow paths to completely prevent vacuum formation in the critical flow areas, even though this may slightly reduce overall insulation efficiency. The air flow action is excessive in the sense that it fully eliminates the harmful vacuum effect rather than merely mitigating it, ensuring reliable tea water flow.
3Manufacturing precision
If filtering holes are made small for effective filtration, then tea leaf separation is improved, but vacuum and surface tension block water flow through the filtering holes
Solution Approach 1:
The filter's functionality is segmented into two distinct mechanisms: the filtering holes handle tea leaf separation with their small孔径, while the open slots in the air flow guiding structure handle the pressure balance and vacuum prevention. This segmentation allows the filtering holes to maintain small sizes for effective filtration without being constrained by the need for large water flow paths.
Solution Approach 2:
The air flow guiding structure serves as an intermediary that compensates for the limited water flow capacity of the small filtering holes. By introducing air flow paths that prevent vacuum formation, it mediates the pressure differential that would otherwise block water flow through the small filtering holes, ensuring reliable water flow while maintaining effective filtration.

Function Achieved in This Case
This solution prevents tea water retention in the lid body, avoids scalding, and enhances the separation of tea leaves and water, improving the usability and safety of the tea drinking vacuum flask.
Implementation Method 1
the air flow flows, through the open slots, from the area under the filtering element of the tea drinking vacuum flask with a tea-making function to the area above the filtering element, so that the formation of a vacuum state in the lid body is avoided
Implementation Method 2
filtering holes are formed in the second part... enabling the separation of tea leaves and water
Implementation Method 3
tea water remains on the top of the vacuum flask due to the vacuum formed on the top of the vacuum flask
Implementation Method 4
the liquid is blocked by vacuum and water surface tension
