Solution Overview
Problem
Batch brewers for brewing larger quantities of coffee suffer from imprecise dosage of coffee grounds, leading to inconsistent brewing strength, and the addition of cold or warm water affects the filtration and temperature of the coffee, causing unwanted cooling and temperature differences.
Innovation Solution
A preparation device with a holder and receiving vessel design that separates the flow of additional water from the brewing process, allowing for simultaneous adjustment of beverage concentration and temperature, using a channel and deflecting elements to mix the flows optimally.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If additional cold or warm water is added to the brewed coffee through the filter paper holder, then the beverage concentration can be adjusted, but the filter paper is wetted from the outside and the coffee is cooled, negatively affecting filtration and temperature stability
Solution Approach 1:
The filter paper holder is divided into two separate water supply systems: one for brewing coffee through the filter paper and another for adding additional water to the brewed beverage. This segmentation prevents the additional water from contacting the filter paper, avoiding wetting and cooling issues while still allowing concentration adjustment.
Solution Approach 2:
The function of adding additional water to adjust beverage concentration is extracted from the brewing path and placed into a separate post-brewing path. The additional water is supplied directly to the brewed coffee in the cup rather than being mixed with the brewing water, thereby separating the concentration adjustment function from the filtration process.
2Adaptability or versatility
If a separate channel is provided for additional water supply, then beverage concentration can be adjusted independently, but the device complexity increases with separate valves, outlets, and supply lines
Solution Approach 1:
The holder for bulk material and the filter paper holder are combined into a single integrated component. The holder shell element and holder base element together form both the bulk material containment structure and the filter paper support structure, eliminating the need for separate components and reducing overall device complexity.
Solution Approach 2:
The holder structure serves multiple functions: it contains the bulk material, supports the filter paper, and provides pathways for both brewing water and additional water. This multi-functionality reduces the number of separate components needed while maintaining independent control over beverage concentration.
3Ease of operation
If manual coffee placement is used in batch brewers, then the device is simple to operate, but the dosage is imprecise leading to inconsistent brewing strength
Solution Approach 1:
The system provides self-service dosage control through the bulk material holder, which allows precise measurement and controlled dispensing of coffee grounds into the filter paper. The holder design with its specific geometry and water flow paths enables consistent dosing without requiring complex automated mechanisms, maintaining ease of operation while improving precision.
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
Ensures consistent brewing strength and temperature stability by preventing cold water from affecting the filtration process, allowing for precise control of beverage concentration and temperature, reducing heat loss and ensuring uniform mixing.
Implementation Method 1
The channel (9) is designed to transport additional water, which can be directed through the channel (9) to the outlet opening (6) of the receiving container (3)
Implementation Method 2
the beverage is mixed with the cold or warm water by the eccentric arrangement of the receiving container outlet opening (6) in the receiving container base element (5)
