Single serve brewing machine
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current single serve brewing systems require separate machines for high and low water pressure brewing, leading to double acquisition costs, energy use, counter space consumption, and maintenance, as well as limitations in offering a variety of beverages due to incompatible cartridge geometries and pressure requirements.
Innovation Solution
A single serve brewing machine with multiple preparation zones and a cartridge sorter that can detect cartridge geometry and select the appropriate zone, allowing for variable water pressure brewing of different beverage types using a universal cartridge acceptance system, including sensors and a transfer sub-assembly for secure handling and brewing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate dispensing systems are used for high water pressure (espresso) and low water pressure (drip-style) brewing, then each system can be optimized for its specific beverage type, but the user must purchase and maintain two separate machines, doubling acquisition costs, energy use, counter space consumption, and maintenance requirements
Solution Approach 1:
The patent implements a universal dispensing system that can accept and brew both espresso-style cartridges (requiring high water pressure) and drip-style cartridges (requiring low water pressure) using a single machine. The system includes a cartridge receiver with a cartridge holder that can accommodate different cartridge types, and a water delivery system with controllable pressure that adapts to the specific beverage type being prepared, eliminating the need for separate dedicated machines for each beverage style
Solution Approach 2:
The patent employs dynamic water pressure control within a single dispensing system. The water delivery system can vary its output pressure based on the type of cartridge inserted and the desired beverage type, allowing the machine to switch between high pressure for espresso and low pressure for drip-style brewing. This dynamic adaptability enables one machine to perform functions previously requiring two separate static systems
2Reliability
If cartridges are designed with different geometries for espresso and drip-style brewing, then each cartridge can be optimized for its specific brewing method, but cartridges become non-interchangeable and users must purchase multiple types of cartridges
Solution Approach 1:
The cartridge holder is designed with universal compatibility features that allow it to securely accommodate both espresso-style cartridges and drip-style cartridges with different geometries. The holder includes adjustable components and a standardized receptacle design that can adapt to various cartridge shapes and sizes, enabling a single cartridge type to work with both espresso and drip-style brewing modes in the same machine
3Device complexity
If a single machine is designed to accommodate multiple cartridge types and brewing methods, then acquisition costs and counter space are reduced, but the machine must handle diverse cartridge geometries and pressure requirements
Solution Approach 1:
The system performs preliminary identification of the inserted cartridge type through sensors or detection mechanisms before initiating the brewing process. Based on this preliminary detection, the system automatically configures the appropriate brewing parameters including water pressure, temperature, and flow rate, and positions the cartridge holder correctly. This preliminary action allows the single machine to seamlessly adapt to different cartridge types without requiring manual configuration or complex user intervention

AI summary
According to embodiments described in the specification, a brewing machine has a machine body that includes a plurality of single serve preparation zones. Each single serve preparation zone corresponds to a preparation parameter. The machine body also includes a cartridge acceptor configured to receive a single serve cartridge, a cartridge sorter configured to determine a parameter of the received cartridge and select one of the plurality of single serve preparation zones according to the determined parameter, a transfer sub-assembly configured to transfer the cartridge to the selected single serve preparation zone, and a fluid dispenser for preparing the beverage using the cartridge in the selected single serve preparation zone.
