Solution Overview
Problem
Existing beverage preparation systems using centrifugal forces struggle to precisely control extraction parameters such as rotational speed, pressure, and temperature, making it difficult to produce beverages with varying characteristics like intensity, taste, and crema quality, especially for different coffee volumes.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional pressure pump brewing methods are used, then beverage preparation is simple, but extraction parameters (pressure, flow rate, temperature) cannot be precisely controlled
Solution Approach 1:
The patent replaces the traditional pressure pump mechanical system with a centrifugal extraction system. The centrifugal extraction unit rotates the capsule at controlled speeds to generate centrifugal force, which naturally creates the pressure gradient needed for extraction. This substitution allows precise control of extraction parameters through rotational speed control rather than complex pressure regulation mechanisms.
Solution Approach 2:
The patent implements precise control of extraction parameters by varying rotational speed, flow rate, and temperature independently. The control system adjusts these parameters based on capsule type recognition, enabling optimization of extraction for different coffee varieties without requiring complex mechanical pressure regulation systems.
2Manufacturing precision
If centrifugal extraction is used, then flow rate can be controlled through rotational speed, but precise control of multiple extraction parameters simultaneously remains difficult
Solution Approach 1:
The patent incorporates sensors that monitor extraction parameters in real-time and feed this information back to the control system. The control unit adjusts rotational speed, flow rate, and temperature based on this feedback to maintain optimal extraction conditions, enabling precise control of multiple parameters simultaneously through automated closed-loop control.
Solution Approach 2:
The centrifugal extraction unit serves multiple functions: it rotates the capsule to generate centrifugal force for extraction, controls flow rate through rotational speed, and can be integrated with heating elements for temperature control. This multi-functionality allows precise control of multiple extraction parameters through a single integrated system rather than separate control mechanisms.
3Adaptability or versatility
If fixed brewing parameters are used, then system operation is simple, but beverage quality varies for different capsule types and volumes
Solution Approach 1:
The patent implements capsule type recognition before brewing begins. The system reads identification information from the capsule (such as RFID tags, barcodes, or NFC identifiers) and pre-loads the appropriate brewing parameters into memory. This preliminary action enables the system to automatically adapt to different capsule types and prepare the optimal extraction profile before the brewing process starts.
Solution Approach 2:
The patent implements dynamic adjustment of brewing parameters during the extraction process. The control system modifies rotational speed, flow rate, and temperature in real-time based on the capsule type, desired beverage volume, and extraction phase. This dynamic control enables the system to produce various beverage types (espresso, lungo, caffe latte) from the same capsule by varying parameters during brewing.
