Solution Overview
Problem
Existing coffee brewing systems using centrifugal forces face challenges with manual dosing and handling, inconsistent coffee quality due to uncontrolled extraction parameters, and difficulty in maintaining coffee freshness, leading to limited commercial success.
Innovation Solution
A capsule system with a sealed enclosure containing a predetermined dose of coffee, connected to external rotational driving means, featuring a roughened or toothed surface for torque resistance and radial outlets for brewed liquid, allowing for controlled centrifugal brewing with improved coffee quality and convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If manual dosing of coffee powder is used in non-removable receptacles, then device complexity is reduced, but manufacturing precision of dosage and coffee freshness control deteriorate
Solution Approach 1:
The coffee preparation system is segmented into separate functional components: a reusable brewing device and disposable pre-dosed capsules. The capsule contains pre-measured coffee powder in a sealed container, separating the dosing function from the brewing device. This allows the device to remain simple while achieving precise dosage control through factory-prepared capsules.
Solution Approach 2:
Coffee powder is pre-dosed and pre-packaged into capsules before use. The capsule is prepared in advance with the exact amount of coffee needed, eliminating the need for manual dosing during operation. This preliminary action ensures consistent dosage precision while keeping the brewing device simple.
2Reliability
If centrifugal brewing with removable holders is used, then coffee freshness is improved, but ease of operation deteriorates due to intensive manual handling
Solution Approach 1:
The invention employs disposable single-use capsules that are discarded after one brewing cycle. Each capsule is hermetically sealed to preserve coffee freshness until use, then disposed of after brewing. This eliminates the need for cleaning and complex manual handling of removable holders while maintaining coffee freshness through sealed packaging.
Solution Approach 2:
The capsule is designed to be self-contained with all necessary components for brewing. The capsule itself serves as both the coffee container and the brewing chamber, eliminating the need for separate removable holders that require assembly and cleaning. Users simply insert the complete capsule and discard it after use.
3Speed
If high pressure pumps are used for espresso brewing, then extraction speed is improved, but reliability of extraction parameters deteriorates
Solution Approach 1:
The invention replaces the high-pressure pump mechanical system with a centrifugal extraction system. Instead of forcing water through coffee powder using high pressure, the capsule is rotated at controlled speeds to generate centrifugal force that drives water through the coffee. This substitution provides more reliable and controllable extraction parameters through precise rotational speed control while maintaining efficient extraction speed.
Solution Approach 2:
The brewing system transitions from static high-pressure extraction to dynamic centrifugal extraction. The capsule rotates during brewing, creating dynamic centrifugal forces that control water flow through the coffee powder. The rotational speed can be precisely controlled and adjusted, providing reliable extraction parameters that are easier to master than high-pressure systems.
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
The system achieves higher coffee solids content and creamier crema with uniform water distribution, reducing manual handling and enhancing coffee freshness, resulting in more consistent and higher-quality brewing compared to traditional methods.
Implementation Method 1
by passing water through the substance contained in the capsule by using brewing centrifugal forces
Implementation Method 2
The roughened portion thus creates a sufficient resistance to the driving surface of the device that enables to drive the capsule in rotation

AI summary
A capsule for preparing a beverage or liquid food from a substance, in a centrifugal brewing unit, by passing water through the substance contained in the capsule by using brewing centrifugal forces. The capsule includes an enclosure containing a predetermined dose of substance, an opening member which opens the capsule under the centrifugal effect to allow the brewed liquid to leave the capsule. The capsule may also include externally driving the capsule in a centrifugal brewing device wherein the capsule includes a structure configured to offer resistance to torque during rotation of the capsule for maintaining the capsule in a reference rotational position.
