Rotating Brewing Material Holder for Faster Cold-Brew Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cold-brewing systems are time-consuming and require complex, bulky devices with external motors, making them difficult to clean and prone to bacterial contamination, while lacking flexibility for both hot- and cold-brewing options and compactness.
Innovation Solution
A beverage brewer with a rotating brewing material holder driven by an electric motor and reduction gears, allowing for both hot and cold brewing, using a serving vessel as the fluid source, and featuring a compact design with a drive assembly that agitates the brewing material to speed up the process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If conventional cold-brewing systems are used, then brewing time is reduced, but device complexity and size increase due to external motors and gravity feed systems
Solution Approach 1:
The patent combines the motor, gears, and brewing material holder into a single integrated drive assembly that fits within the brewing container. This merging eliminates the need for external motors and separate gravity feed systems, reducing device complexity while maintaining the ability to agitate brewing material for faster cold brewing.
Solution Approach 2:
The drive assembly is designed to nest within the brewing container, with the motor and gears positioned inside the container volume. The brewing material holder is suspended from the container collar and can be rotated by the drive assembly. This nesting approach maximizes space utilization and eliminates the need for external components.
2Loss of time
If conventional cold-brewing systems with external motors are used, then brewing time is reduced, but ease of operation deteriorates due to difficulty in cleaning and bacterial contamination risks
Solution Approach 1:
The drive assembly is designed as a removable unit that can be separated from the brewing container. The motor, gears, and brewing material holder form a self-contained assembly that can be easily removed for cleaning. This segmentation allows users to clean the brewing container and holder separately, improving ease of operation and reducing bacterial contamination risks.
Solution Approach 2:
The drive assembly is extracted from the brewing container as a separate removable unit. The motor and gears are positioned such that the entire drive assembly can be lifted out for cleaning, eliminating the need to disassemble complex internal mechanisms. This extraction approach significantly improves ease of cleaning and maintenance.
3Volume of moving object
If a compact brewer design is implemented, then portability is improved, but adaptability deteriorates due to limited capacity for different brewing materials
Solution Approach 1:
The brewing material holder is designed with a universal interface that can accommodate different types of brewing materials, including ground coffee, whole beans, tea leaves, and other infusables. The holder's open top and mesh bottom allow various materials to be loaded, and the rotation mechanism works effectively with all material types. This universality enables a compact design to handle diverse brewing needs.
Solution Approach 2:
The drive assembly provides dynamic rotation of the brewing material holder, creating agitation that enhances extraction for different brewing materials. The rotational motion adapts to various material densities and sizes, allowing the compact brewer to effectively process different brewing materials without requiring separate specialized chambers or mechanisms.
