Curved Pedestal Cold Brewing Without Filter-Bag Squeezing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cold brewing systems often produce harsh acids and oils in the brewed effluent due to incomplete drainage and handling methods, which can contaminate the beverage and affect its taste.
Innovation Solution
A brewing system with a curved pedestal and faucet design that allows for efficient drainage of brewed effluent to a minimum level, reducing the weight of the filter bag and preventing harsh substances from entering the effluent, while using a filter bag on a pedestal with holes to facilitate full drainage and prevent bag tearing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the filter bag is squeezed or pushed to drain effluent, then drainage efficiency is improved, but harsh oils and harsh acids enter the brewed effluent contaminating it
Solution Approach 1:
The pedestal features a curved surface that is curved downwardly towards a middle portion, creating a central drainage zone. This curvature allows effluent to naturally concentrate and drain toward the center through gravity alone, eliminating the need to squeeze or push the filter bag. The curved geometry facilitates complete drainage while preventing contamination of the brewed effluent with harsh substances.
2Quantity of substance
If the filter bag is allowed to retain all effluent, then harvesting efficiency is improved, but the filter bag becomes heavy and susceptible to tearing when removed
Solution Approach 1:
The curved pedestal surface concentrates effluent toward the middle portion where drainage occurs, enabling the filter bag to drain completely. This design allows the filter bag to be lightweight enough for easy removal while still achieving high effluent yield through the concentrated drainage path created by the curved geometry.
3Ease of manufacture
If the pedestal is flat, then manufacturing simplicity is improved, but effluent drainage and concentration efficiency deteriorates
Solution Approach 1:
The pedestal incorporates a curved surface that is relatively simple to manufacture while dramatically improving effluent drainage efficiency. The curvature concentrates effluent toward the center, creating an efficient drainage path without requiring complex manufacturing processes. This balances manufacturing simplicity with enhanced drainage productivity.
4Ease of operation
If the faucet is positioned high in the bucket, then ease of operation is improved, but the ability to drain effluent to minimum level and prevent sediment contamination deteriorates
Solution Approach 1:
The system uses the vertical dimension created by the curved pedestal to separate the drainage function from the faucet position. The curved surface guides effluent downward to a minimum level near the bucket bottom, while the faucet remains accessible at a higher position. This dimensional separation allows the faucet to be easily accessible while still enabling complete drainage below the effluent level, preventing sediment contamination.
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 system effectively prevents harsh acids and oils from entering the brewed effluent, maintaining a better taste and reducing the risk of filter bag damage, while ensuring a sanitary and efficient brewing process.
Implementation Method 1
the pedestal having a curved surface that is curved downwardly towards a middle portion of the pedestal so that effluent drains towards a central portion of the pedestal and the effluent is concentrated towards a middle portion of the filter bag
Implementation Method 2
placing an organic material, used to create the brewed effluent, in a filter bag

AI summary
Included is a brewing system that utilizes a curved pedestal that allows brewed effluent to drain in a manner that travels toward the center of the curved pedestal to maximize the exposure of the effluent to the organic material used for brewing, while also maximizing yield. The pedestal 112 sits above the lowest effluent level to allow the brewed effluent to drain from the organic material that is used for brewing to maximize the amount of effluent obtained. By allowing the brewed effluent to drain from the organic material, the weight and size of the organic material is reduced, so that the filter bag can be removed from the brewing system without ripping or tearing. The brewing system eliminates the need for a separate mesh bag and allows the effluent to drain without squeezing the filter bag and which would otherwise cause the release of harsh oils and acids, which can also be unsanitary as a result of a user handling the bag filter.
