Solution Overview
Problem
Conventional cold brewing methods often result in coffee with suspended solids, which are aesthetically unappealing and can settle at the bottom of the container, and may produce acidic and harsh tastes due to hot brewing methods.
Innovation Solution
The apparatus consists of an extract tank with a false bottom and an inverted P-trap mechanism connected to a brew tank via a low-flow pump system, allowing for controlled brewing without suspended solids by depositing water above the coffee bed and using a mister for efficient extraction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If hot water is used for brewing coffee, then the mixing speed with grounds is improved, but the taste becomes acidic and harsh
Solution Approach 1:
The patent changes the temperature parameter of the brewing water from hot to cold. This parameter change slows down the mixing speed with coffee grounds but eliminates the acidic and harsh taste, producing a smoother flavored coffee while the porous filter ensures proper extraction and filtration.
2Ease of manufacture
If conventional filters (cloth, paper, metal) are used for cold brewing, then the brewing process is simple, but suspended solids remain in the liquid
Solution Approach 1:
The patent replaces conventional filters (cloth, paper, or metal) with a filter bed comprising porous material at the bottom of the brewing chamber. This porous filter effectively traps suspended solids while maintaining a simple brewing process, producing visually appealing cold brew without requiring complex filtration systems.
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
This method effectively reduces the presence of suspended solids in cold brewed coffee, improves taste by avoiding acidity, and allows for easy cleaning and high yield, resulting in a cleaner and more palatable cold brew.
Implementation Method 1
the extract tank has a false bottom for filtering a coffee bed from water infused in the extract tank
Implementation Method 2
the extract tank and the brew tank are connected with an inverted P trap mechanism and the low flow pump pipe system

AI summary
A cold brewing coffee device that produces coffee without any suspended solids in the product. The devices uses a false bottom in the initial tank to hold the coffee beans and water is pumped between the initial tank and a second tank. Using an inverted P trap in the piping allow for reduced suspended solids in the final product. The end product is a high quality cold brewed beverage that is defined by the beverages clarity and lack of visible suspended solids, wherein the resulting product has a distinct look compared to other brewed beverages (i.e. producing a product that is cleaner than competing products without the need for a filter).
