Solution Overview
Problem
Existing filter vessels for coffee preparation often fail to ensure uniform filling of multiple containers due to uneven flow rates through multiple discharge openings, which can be concealed by the filter paper insert, making reproducible filling of multiple cups difficult.
Innovation Solution
A filter vessel with a central separating element dividing the bottom into two drainage chambers, each with at least one opening, ensuring uniform distribution of the filtrate and allowing for simultaneous filling of two containers, with optional guide elements and ribs to enhance flow behavior and positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple openings are provided in the bottom area to increase outflow quantity, then the flow rate at individual discharge openings becomes different, but the ability to fill multiple containers simultaneously is improved
Solution Approach 1:
The filter vessel bottom is segmented into multiple drainage chambers (first and second drainage chambers) with separate openings, allowing independent control of flow paths to multiple containers simultaneously, thus increasing productivity while maintaining uniform filling
Solution Approach 2:
Each drainage chamber is equipped with specific local features including guide elements (first guide element, second guide element) and ribs (first bottom rib, second bottom rib) that optimize flow distribution locally at each opening, ensuring uniform flow rates despite multiple discharge points
2Device complexity
If an outlet opening is partly concealed by a filter paper insert, then the filter vessel structure is simpler, but uniform filling of two cups cannot be guaranteed in a reproducible manner
Solution Approach 1:
Guide elements and bottom ribs are introduced as intermediary structures that mediate between the filter insert and the openings, ensuring that even when the filter paper partially conceals openings, the flow remains uniform and reproducible through the intermediary flow-guiding structures
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 solution enables uniform filling of two containers by ensuring equal supply of filtrate to each chamber, preventing uneven flow and allowing for easy positioning on one or two containers, ensuring consistent coffee distribution.
Implementation Method 1
a bottom (19) including at least two openings (9, 10) through which a filtrate can pass
Implementation Method 2
the bottom (19) includes a central region and a separating element in the central region of the bottom, the separating element dividing a region above the bottom into two approximately equal sized drainage chambers
Implementation Method 3
a filter vessel for accommodating a filter insert made of water-permeable material, by which uniform filling of two containers is possible

AI summary
A filter vessel for accommodating a filter insert made of water-permeable material and fillable with coffee grounds. The filter vessel includes a bottom; and side walls upwardly extending from the bottom and spreading outwardly. The bottom includes at least two openings through which a filtrate can pass. The bottom includes a separating element in a central region of the bottom. The separating element divides a region above the bottom into two approximately equal sized drainage chambers. Each drainage chamber includes at least one of the at least two openings for discharging the filtrate.
