Rotational Brewing Chamber for Multi-Beverage Preparation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Households often require multiple separate appliances for making various beverages like tea, coffee, frothed milk, soup, and soya milk, which is inconvenient and inefficient.
Innovation Solution
A multi-functional appliance with a container having a heated base and a rotating member that can function as an impeller, whisk, or cutting blade, allowing for brewing, frothing, and cutting, with a removable brewing chamber to separate liquids from solids, and the ability to adjust temperature and rotation speed for different beverages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate appliances are used for making different beverages (tea, coffee, frothed milk, soup, soya milk), then each appliance can be optimized for its specific function, but the device complexity and space requirements increase significantly
Solution Approach 1:
The appliance integrates multiple beverage preparation functions into a single device. The container can function as a brewing vessel for tea and coffee, a frothing container for milk, and a blending container for soup and soya milk. The rotating member can be configured as a tea infuser, coffee tamper, milk frothing whisk, or blending blade depending on the desired function.
Solution Approach 2:
The appliance employs a controllable rotating member that can operate at different speeds and configurations. The rotation speed can be adjusted to suit different functions: slow rotation for tea infusing, medium rotation for coffee tamping and frothing, and high rotation for blending. This dynamic adaptability allows one device to replace multiple specialized appliances.
2Productivity
If a wire mesh basket is used to remove tea leaves, then tea brewing function is achieved, but the device complexity increases and the basket requires additional space within the container
Solution Approach 1:
The tea leaf removal function is extracted from a separate basket structure and integrated into the rotating member itself. The rotating member can function as a tea infuser with perforations or as a mechanism that allows water to pass through while retaining leaves, eliminating the need for a separate wire mesh basket.
Solution Approach 2:
The rotating member serves multiple functions: it acts as a tea infuser for tea brewing, a tamper for coffee preparation, a whisk for milk frothing, and a blending blade for soup and soya milk. This multi-functionality eliminates the need for separate components for each function, reducing overall device complexity.
3Productivity
If high pressure (8-15 bar) is used for espresso coffee machines, then coffee extraction efficiency is improved, but the device complexity and safety requirements increase
Solution Approach 1:
The appliance operates at lower pressure compared to traditional espresso machines. Instead of forcing water through coffee at 8-15 bar, the system uses a pouring mechanism where water is added to the container and circulated through the coffee grounds using the rotating member at controlled speeds, achieving effective extraction without high pressure.
4Adaptability or versatility
If a rotating member with fixed function is used, then the appliance is simple to manufacture, but the adaptability to make different beverages is limited
Solution Approach 1:
The rotating member is designed to be adjustable and reconfigurable. It can operate at different rotation speeds suitable for different functions: slow rotation for tea infusing, medium rotation for frothing, and high rotation for blending. This dynamic capability allows a single rotating member design to replace multiple fixed-function components.

AI summary
An appliance for making beverages comprises a container (110) for liquid, means for creating a rotational movement (203) of the liquid to raise a level of the liquid, and a brewing chamber (400) mounted between a normal level of the liquid, when the means for creating a rotational movement (203) is not rotating, and a raised level of the liquid, when the means for creating a rotational movement (203) is rotating, so that the liquid flows into the brewing chamber (400) when the means for creating a rotational movement (203) is rotating above a predetermined speed.
