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 existing brewing technologies do not effectively address the issue of acidic and harsh taste associated with hot brewed coffee.
Innovation Solution
A cold brew coffee device comprising an extract tank with a false bottom, a brew tank, inverted P-trap piping, and pumped piping, which allows for controlled brewing without suspended solids and improved taste by using a sparge arm and mister system to manage water flow and extraction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If hot water is used for brewing coffee, then the coffee mixes with grounds much quicker, but the taste becomes acidic and harsh
Solution Approach 1:
The brewing system changes the temperature parameter of the water from hot to cold. By using cold water instead of hot water, the system accepts slower mixing speed as a trade-off to eliminate the harmful acidic and harsh taste, thus optimizing the taste quality parameter.
2Ease of operation
If cloth, paper or metal filters are used for cold brewing coffee, then brewing can proceed, but suspended solids remain in the liquid
Solution Approach 1:
The system extracts and removes suspended solids from the brewed coffee by transferring it to a second tank that functions as a filtration chamber. This extraction process separates the harmful suspended solids from the desirable coffee liquid, producing a clear final product.
Solution Approach 2:
The pump serves as an intermediary that facilitates the transfer of brewed coffee from the brewing tank to the filtration tank, enabling the filtration process to occur without direct manual intervention and maintaining ease of operation.
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 device produces high-quality cold brewed coffee without suspended solids, offering improved taste and ease of cleaning, while maintaining a high yield comparable to other brewing methods.
Implementation Method 1

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).
