Coffee or Tea Filtering Device with Vacuum-Assisted Brewing and Mixing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional coffee and tea filtering devices that use pressure to force fluid through coffee grounds or tea leaves are sealed during the process, preventing mixing and stirring, which can enhance the brewing process.
Innovation Solution
A coffee or tea filtering device comprising a hollow cylinder, a basket, and a pump that allows air to be pumped out, creating a pressure gradient to force fluid through coffee grounds or tea leaves while maintaining a sealed environment for the brewed liquid, enabling mixing and stirring during the pressurized filtering process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the fluid and coffee grounds or tea leaves are placed in a sealed environment during pressurized filtering, then the filtering process can be completed, but mixing and stirring actions cannot be performed to assist the brewing process
Solution Approach 1:
The device divides the brewing system into separate functional zones: a brewing chamber where mixing occurs and a filtering chamber where pressure application occurs. This segmentation allows stirring actions in the brewing chamber while maintaining the sealed environment needed for pressurized filtering in the filtering chamber.
Solution Approach 2:
The device incorporates a movable barrier or partition that can be positioned to separate the brewing and filtering zones during different phases of operation. This dynamic element allows the system to transition between mixing mode and filtering mode while maintaining environmental control.
2Ease of operation
If the fluid and coffee grounds or tea leaves are kept accessible during pressurized filtering, then mixing and stirring can be performed, but the environment cannot remain sealed
Solution Approach 1:
The device creates distinct operational zones separated by a movable barrier. The first chamber allows accessible mixing and stirring operations, while the second chamber maintains a sealed environment for pressurized filtering. The barrier can be repositioned to control access and maintain seals as needed.
3Ease of operation
If a movable barrier is used to separate brewing and filtering zones, then mixing can occur in the first chamber, but the barrier must be movable to allow fluid transfer
Solution Approach 1:
The movable barrier is designed to be actuated by the user through simple manual operation, such as pushing or sliding, without requiring complex mechanical systems. The barrier's movement is directly coupled to the fluid transfer mechanism, so that moving the barrier itself initiates the brewing process.

AI summary
A coffee or tea filtering device including a hollow cylinder, a basket, a cup, and a pump. The hollow cylinder may include a top end, a bottom end, and a curvate sidewall extending between the top end and bottom end. The top may be open. The bottom end may be at least partially open and include a first portion of a coupling mechanism and a retaining portion. The removable basket may be sized to be received within the top end of the hollow cylinder. The removable basket may be configured to support coffee grounds or tea leaves. The cup may releasably couple to the first portion of the coupling mechanism of the bottom end of the hollow cylinder. The pump may be configured to pump air from the cup out the opening so as to force a fluid from the hollow cylinder through the basket and into the cup.
