Coffee brewing system and method of brewing coffee
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coffee preparation systems lack integration of roasting, grinding, and brewing phases, leading to uneven roasting, inconsistent grinding, and suboptimal brewing conditions due to the absence of a unified mechanism that synchronizes temperatures and timings across these phases.
Innovation Solution
A coffee brewing system integrating a horizontally mounted cylinder roaster with helical mixing blades and electric heat, a vertically oriented burr grinder, and a detachable brewing chamber with an interactive display screen, allowing for seamless transition from roasting to grinding to brewing within a single unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If separate equipment is used for roasting, grinding, and brewing, then each phase can be optimized independently, but the overall coffee preparation process becomes disjointed and inconsistent
Solution Approach 1:
The patent combines roasting, grinding, and brewing functions into a single integrated coffee preparation system. The roasting chamber, grinding mechanism, and brewing apparatus are merged into one device, allowing seamless transition between phases and ensuring consistent coffee preparation from bean to cup.
Solution Approach 2:
The coffee preparation system performs multiple functions within a single device: it can roast coffee beans, grind them to various consistencies, and brew the final beverage. This multi-functional design eliminates the need for separate equipment while maintaining optimization of each phase.
2Manufacturing precision
If traditional roasting equipment is used without effective mixing, then the roasting process is simple, but uneven roasting occurs due to inadequate heat distribution and bean agitation
Solution Approach 1:
The roasting mechanism incorporates a mixing blade that rotates to agitate and tumble the coffee beans during the roasting process. This mechanical motion ensures uniform heat distribution across all beans and prevents hot spots, achieving even roasting throughout the batch.
3Manufacturing precision
If grinder design is simplified, then the device is easier to manufacture, but it cannot achieve the desired uniformity for optimal coffee extraction
Solution Approach 1:
The system replaces traditional blade grinding with a burr grinding mechanism. Two burrs (one stationary, one rotating) crush the coffee beans between their surfaces, producing a uniform and consistent grind size. This mechanical substitution significantly improves grind uniformity compared to simpler blade-based systems.
4Manufacturing precision
If brewing is not integrated with roasting and grinding, then the brewing process can be simplified, but suboptimal brewing conditions result due to lack of temperature and timing synchronization
Solution Approach 1:
The system enables continuous operation where roasted beans are immediately transferred to the grinder, and ground coffee is promptly brewed. This continuous flow eliminates delays and temperature losses between phases, maintaining optimal conditions throughout the preparation process.
Solution Approach 2:
The system performs preliminary roasting and grinding actions before brewing, with each phase prepared and ready for the next. The roasting completes first, followed immediately by grinding, which then feeds directly into brewing, ensuring each phase is optimally prepared before the next begins.
