Solution Overview
Problem
Conventional coffee brewing systems are inefficient as they often result in coffee waste, inconsistent flavor, and require significant labor and time for cleaning and maintenance, especially in commercial settings where coffee is brewed in large batches and not to order.
Innovation Solution
A system comprising multiple brew modules with automated features such as hopper management, automatic cleaning, and airflow control to prevent steam and condensation, allowing for rapid brewing of single-cup portions of coffee with improved flavor consistency and reduced maintenance time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If automated single-cup brewing systems are used, then coffee waste is reduced and freshness is improved, but brewing time and cleaning complexity increase
Solution Approach 1:
The system divides the brewing function into multiple independent brew modules (first brew module, second brew module, third brew module), each capable of brewing single-cup portions simultaneously. This segmentation allows parallel processing of multiple orders, reducing total brewing time while maintaining the single-cup freshness advantage.
Solution Approach 2:
The doser assembly pre-doses coffee beans into precise portions before brewing, and the wiper assembly performs automatic cleaning immediately after each brew cycle. These preliminary and follow-up actions streamline the brewing process, reducing overall cycle time while preventing coffee waste through precise dosing.
2Loss of substance
If automated single-cup brewing systems are used, then coffee waste is reduced and freshness is improved, but cleaning time and labor increase
Solution Approach 1:
The wiper assembly automatically cleans the upper subassembly after each brew cycle without human intervention. This self-cleaning mechanism significantly reduces the manual cleaning effort required, addressing the ease of operation concern while maintaining the benefits of automated single-cup brewing.
Solution Approach 2:
The wiper assembly extracts and removes coffee residue and contaminants from the brewing components after each cycle. By actively removing waste materials, the system reduces cleaning complexity and maintains hygiene without requiring extensive manual intervention.
3Device complexity
If steam and condensation are allowed to enter grinder and hopper areas, then system complexity is reduced, but coffee quality deteriorates and corrosion increases
Solution Approach 1:
A barrier or protective structure is introduced between the brewing area (where steam and condensation are generated) and the grinder/hopper areas. This intermediary element prevents moisture ingress while maintaining system functionality, protecting coffee quality and preventing corrosion without requiring overly complex redesign.
Solution Approach 2:
The system takes preliminary actions to prevent steam and condensation from reaching the grinder and hopper areas before moisture damage can occur. This proactive protection approach maintains coffee quality and prevents corrosion while keeping the overall system design relatively simple.
4Productivity
If multiple brew modules are used, then productivity is improved, but device complexity increases
Solution Approach 1:
The system is divided into multiple identical brew modules (first, second, and third brew modules), each with its own doser assembly, upper subassembly, interior subassembly, and dispensing portion. This modular segmentation increases productivity through parallel brewing while keeping each module relatively simple and standardized.
Solution Approach 2:
Each brew module is designed as a universal, multi-functional unit that can independently complete the entire brewing process from dosing to dispensing. This universality allows multiple modules to work in parallel, increasing overall productivity without requiring complex integration between different types of components.
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 enables quick brewing of single-cup coffee in under 30 seconds, reduces waste and labor, and maintains coffee quality by ensuring freshness and consistency, while also simplifying maintenance and cleaning processes.
Implementation Method 1
The first interior subassembly comprises a first piston configured to raise and lower coffee grounds during a brew cycle
Implementation Method 2
The first upper subassembly comprises a first wiper assembly for automatically cleaning the upper subassembly after a brew cycle
Implementation Method 3
The first dispensing portion is engaged with the first interior subassembly and is configured to provide brewed coffee to a drinking receptacle after a brew cycle
