Cold Brew Adapter Assembly for Pour-Over Coffee System Conversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current brewing systems cannot efficiently produce both hot pour over coffee and cold brew coffee using the same device, as they require different brewing methods and times, with hot pour over coffee being immediate and cold brew taking several hours.
Innovation Solution
A cold-brew adapter system that includes an adapter assembly to interface with a pour-over coffee system, a steeping assembly for ground coffee, and an agitator assembly for agitation, allowing for a watertight seal and enabling the conversion of a traditional pour-over coffee system into a cold brew system by immersing coffee grounds in cold water for an extended period.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional pour-over coffee system is used for hot brewing, then immediate coffee is produced, but cold brew coffee cannot be made with the same device
Solution Approach 1:
The adapter assembly enables the pour-over coffee system to perform multiple brewing functions - both hot pour-over brewing and cold brew immersion brewing - by providing a universal interface that accommodates different brewing methods using the same basic device structure
Solution Approach 2:
The adapter assembly is designed as a separate, removable component that interfaces with the existing pour-over system. This segmentation allows the cold brew functionality to be added without modifying the original device, maintaining simplicity while enabling versatility
2Reliability
If cold brew coffee is brewed using traditional immersion method, then flavor quality is improved, but brewing time increases to at least twelve hours
Solution Approach 1:
The agitator assembly introduces dynamic movement into the traditionally static immersion brewing process. By periodically agitating the coffee grounds during steeping, the system enhances extraction efficiency and flavor quality while potentially reducing the required brewing time compared to passive immersion methods
3Adaptability or versatility
If an adapter assembly is added to enable cold brew functionality, then brewing versatility is improved, but device complexity increases
Solution Approach 1:
The adapter assembly is designed to nest within the existing pour-over coffee system's upper portion. The adapter contains nested components including the steeping assembly and agitator assembly, creating a compact integrated structure that adds functionality without requiring significant additional space or complexity
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
Enables the production of cold brew coffee using a standard pour-over coffee system, reducing brewing time and maintaining flavor quality by allowing immersion brewing within the existing infrastructure, while maintaining the option for hot brewing.
Implementation Method 1
cold brew coffee is brewed using a form of the immersion method, where the coffee is immersed in the cold water and is left to steep for a number of hours
Implementation Method 2
an agitator assembly configured to be removably received within the steeping assembly and enable agitation of the ground coffee contained therein
Data Source
AI summary
A cold-brew adapter system includes: an adapter assembly configured to interface with an upper portion of a pour-over coffee system; and a steeping assembly configured to receive ground coffee and position the ground coffee within a liquid contained in a lower portion of the pour-over coffee system.
