Filtered Beverage Machine With Integrated Hot and Cold Brewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional coffee machines are limited to producing only hot beverages, requiring users to cool down hot coffee to make cold coffee, which is not instantaneous.
Innovation Solution
A machine equipped with both a boiler system for heating water and a cooling system using a coil and compressor to simultaneously prepare and chill beverages, allowing for the production of both hot and cold filtered drinks using capsules or loose coffee.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a coffee machine is designed to make hot beverages only, then the device complexity is reduced, but the adaptability is limited
Solution Approach 1:
The patent combines both heating and cooling systems within a single coffee machine. The boiler (3) heats water for hot beverages, while the cooling machine with coil (22) and compressor (23) cools water for cold beverages. This merging of previously separate functions into one device increases adaptability while managing complexity through integrated design.
Solution Approach 2:
The machine is designed to perform multiple functions: preparing hot espresso coffee, hot tea/infusions, cold coffee, and cold tea/infusions. The universal filter support (7) and joint (8) system accommodates both hot and cold beverage preparations, allowing a single device to serve multiple beverage temperature needs.
2Loss of time
If traditional cooling methods are used for hot coffee, then the beverage can be cooled down, but the preparation time increases
Solution Approach 1:
The cooling machine pre-cools water in tank (25) before the beverage preparation process begins. The coil (22) passes through the pre-cooled water, and the compressor (23) maintains the cooling effect. This preliminary cooling action eliminates the need for post-preparation cooling, reducing total preparation time significantly.
Solution Approach 2:
The patent introduces an intermediary cooling system between the water source and the beverage preparation. The cooling machine with coil (22) and compressor (23) acts as an intermediary that pre-cools water, allowing instant cold beverage preparation without requiring traditional extended cooling methods after coffee preparation.
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 instant preparation of both hot and cold beverages, enhancing user convenience by integrating heating and cooling functions within a single machine.
Implementation Method 1
the cold water coming from the external feed is heated enough to prepare the beverage in the filter and filter support 7
Implementation Method 2
a cooling machine which coil 22, protruding from the compressor 23, passes through a tank 25 full of water or another fluid that can be cooled down
Implementation Method 3
Through said tank 25, which can be considered as a heater exchanger, there passes also a second coil 27 of a capillary conduction feed 28, which allows to cool down the beverages prepared with the heated feeding water of feed 5

AI summary
A machine adapted to make filtered beverages, both hot and cold, provided with a tank for hot water (4) controlled by means of a boiler (3), a supply feed (5) passing through said tank, a heat exchanger (6) on the supply feed located inside the tank and a joint (8) for an already known filter support. Said machine is also provided with a feed (28) connectable to a filter support and provided with a coil (27) which is housed inside a tank for chilled water (25) said coil being adapted to work as heat exchanger between the chilled water and the hot beverage inside the feed (28).
