Coffee Maker Bloom Water Control for Consistent Flavor Profiles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing beverage brewing systems lack the ability to automatically produce beverages with a desired flavor profile, as they do not effectively control variables such as water volume and contact time, leading to inconsistent taste quality across different types and volumes of beverages.
Innovation Solution
An automated beverage brewing apparatus with a controller that adjusts the volume of bloom water and bloom time based on user input for the type and size of beverage, including a heating mechanism to heat water and a showerhead for even distribution, allowing for the preparation of regular, rich, and ultra-rich coffee with specific parameters to achieve desired flavor profiles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed brewing system is used, then the device complexity is reduced, but the adaptability to different beverage types and volumes is poor
Solution Approach 1:
The brewing system employs dynamic control of water flow rate, bloom time, and water temperature based on user-selected beverage parameters. The controller adjusts these variables in real-time according to the desired beverage type and volume, transforming a static system into a dynamic one that adapts to different brewing requirements.
Solution Approach 2:
The system changes key brewing parameters including water flow rate, bloom time, and water temperature to achieve different flavor profiles. By varying these parameters based on the selected beverage type and volume, the system provides adaptability across multiple beverage preparations without requiring fundamentally different hardware configurations.
2Manufacturing precision
If manual brewing control is used, then the ease of operation is improved, but the manufacturing precision of flavor profile is poor
Solution Approach 1:
The system performs self-adjustment of brewing parameters automatically based on pre-programmed profiles. Once the user selects the desired beverage type and volume, the controller autonomously manages water flow rate, bloom time, and temperature control, eliminating the need for manual intervention while ensuring precise flavor profile reproduction.
Solution Approach 2:
The system incorporates sensors to monitor water temperature, flow rate, and brewing progress in real-time. This feedback mechanism allows the controller to make precise adjustments during the brewing process, ensuring consistent flavor profiles across different preparations while maintaining simple user interaction.
3Manufacturing precision
If variable brewing parameters are used, then the flavor profile precision is improved, but the device complexity increases
Solution Approach 1:
The brewing system employs a universal controller that manages multiple brewing parameters (water flow rate, bloom time, temperature) through a single integrated unit. This multi-functional approach allows precise control of flavor profiles without proportionally increasing device complexity, as one controller handles all parameter adjustments.
Solution Approach 2:
The system replaces complex mechanical adjustment mechanisms with electronic control. Digital sensors and microcontroller-based regulation manage water flow, temperature, and timing parameters, achieving precise flavor profile control through software algorithms rather than intricate mechanical 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 apparatus ensures consistent flavor profiles by varying bloom water and brew water volumes and times, achieving optimal strength and extraction percentages for different coffee types, resulting in a balanced and pleasant tasting beverage.
Implementation Method 1
A heating mechanism is arranged in fluid communication with the reservoir and the showerhead. The heating mechanism is configured to heat water delivered from the reservoir to the heating mechanism before supplying it to the shower head.
Implementation Method 2
A shower head adjacent the brew basket is configured to evenly distribute water over the ground coffee.
