Solution Overview
Problem
Cold-brewing methods for coffee and tea require extended times for extraction, which is undesirable for consumers seeking faster brewing without the use of heat, as they often result in less efficient extraction of desired flavor compounds and increased extraction of undesirable compounds.
Innovation Solution
The use of physical motion, such as stirring, mixing, or agitation, in a brewing system to accelerate the extraction process of compounds from solids into a cold or room temperature solvent, without the application of thermal energy, utilizing a device with interchangeable tops that incorporate mechanisms like spinning, tumbling, or solvent circulation to enhance extraction efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If cold or room temperature water is used for brewing, then the extraction of undesirable compounds is reduced and desirable flavor profile is achieved, but the brewing time is significantly increased to 12-24 hours
Solution Approach 1:
The patent applies physical motion (stirring, mixing, or agitation) to the cold-brewing system to accelerate extraction. The brewing vessel incorporates mechanisms such as a spinning porous chamber, tumbling motion, or solvent circulation that dynamically moves the solid and liquid during extraction, reducing brewing time from hours to minutes while maintaining selective extraction of desirable compounds
Solution Approach 2:
The patent changes the physical state parameters of the brewing system by introducing mechanical motion and agitation to the cold-brewing process. This transforms the static extraction process into a dynamic one, increasing mass transfer rates and extraction efficiency without using heat, thereby reducing brewing time while preserving the flavor benefits of cold brewing
2Loss of time
If hot water is used for brewing, then the brewing time is reduced to minutes, but the extraction of undesirable compounds increases resulting in bitter or sharp flavors
Solution Approach 1:
The patent replaces the thermal energy system (hot water) with a mechanical energy system (physical motion and agitation). Instead of using heat to accelerate extraction, the invention uses mechanical motion to enhance mass transfer between the solid and liquid phases, achieving fast extraction without the harmful effects of heat-induced compound extraction
Solution Approach 2:
The patent introduces an intermediary mechanical motion system that mediates between the cold water and solid materials. This intermediary mechanism (stirring, spinning, or tumbling) facilitates rapid extraction of desirable compounds while the cold temperature prevents extraction of undesirable compounds, resolving the contradiction between speed and selectivity
3Productivity
If physical motion is applied to cold-brewing system, then the extraction process is accelerated without thermal energy, but the device complexity increases with interchangeable tops and motion mechanisms
Solution Approach 1:
The patent segments the brewing device into modular components, including an interchangeable top assembly with motion mechanisms that can be attached to or removed from the brewing vessel. This segmentation allows the complex motion-generating components to be separated from the simple brewing chamber, making the system easier to manufacture, clean, and operate while providing advanced extraction capabilities when needed
