Automatic single-serving beverage brewing system
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing capsule-based coffee machines lack the ability to customize brewing parameters such as grind size, water temperature, and coffee-to-water ratio, limiting their ability to extract the full flavor potential of various coffee varieties and resulting in a difference in quality between café-prepared and machine-brewed coffee.
Innovation Solution
A single-serving beverage brewing system with an electronic reader, an adjustable grinder, and a brewer that can adjust grind size and water dispensing parameters based on information from an identification tag on coffee pods, allowing for customizable brewing recipes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If capsule-based coffee machines use fixed brewing settings, then the device complexity is reduced and ease of operation is improved, but the adaptability to different coffee varieties deteriorates and manufacturing precision of extraction parameters is lost
Solution Approach 1:
The brewing system dynamically adjusts extraction parameters (grind size, water temperature, coffee-to-water ratio, pouring methods) based on the specific coffee variety being brewed. The system transitions from static fixed settings to dynamic customizable settings that adapt to different coffee types, enabling users to optimize brewing for each variety while maintaining ease of operation through automated controls.
Solution Approach 2:
The system enables changes in critical brewing parameters including grind size, water temperature, coffee-to-water ratio, and pouring methods. These parameter changes allow the system to adapt to different coffee varieties and extraction requirements, transforming the fixed-parameter capsule machine into a variable-parameter brewing system that can optimize for each coffee type.
2Loss of time
If capsule-based coffee machines use pre-packaged coffee grounds, then the ease of operation is improved and preparation time is reduced, but the freshness of coffee deteriorates and the quality of extraction is limited
Solution Approach 1:
The system performs preliminary grinding of coffee beans immediately before brewing, rather than using pre-ground coffee. This preliminary action maintains coffee freshness by grinding only when needed, preserving volatile aromatic compounds that would otherwise be lost in pre-packaged grounds. The system prepares the coffee grounds in advance of the brewing process itself, optimizing both freshness and efficiency.
3Ease of manufacture
If capsule-based coffee machines use fixed brewing options, then the device complexity is reduced and manufacturing cost is lowered, but the manufacturing precision of extraction parameters deteriorates and the quality of coffee extraction is limited
Solution Approach 1:
The brewing system implements dynamic control over extraction parameters including grind size, water temperature, coffee-to-water ratio, and pouring methods. This dynamic capability enables precise optimization for different coffee varieties and extraction techniques, transforming the manufacturing from fixed-parameter to variable-parameter systems that can achieve café-quality extraction precision.
Solution Approach 2:
The system enables users to act as their own baristas by providing control over multiple extraction parameters. Users can customize brewing recipes and optimize extraction for different coffee varieties, eliminating the need for professional barista intervention while achieving comparable quality through self-service customization capabilities.
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
Enables the production of café-quality coffee at home by allowing users to customize brewing parameters, ensuring maximum flavor extraction and freshness of coffee beans.
Implementation Method 1
a burr assembly configured to receive the coupled movement through the main shaft. The coffee grinder is configured to automatically grind and make powders of coffee beans
Implementation Method 2
any stray particles that escape during the grinding process are collected by a magnetic tunnel situated below the outer burr
Implementation Method 3
a brewer to dispense water for brewing the single-serving beverage from the ground powders

AI summary
A brewing system comprises a grinder, a brewer, a capsule holder, and a controller. The grinder is configured to grind whole coffee beans into coffee grounds with adjustable coarseness. The grinder is configured to receive the whole coffee beans through a first opening above the grinder and dispense the coffee grounds through a second opening below the grinder. The brewer is configured to dispense water for brewing coffee through a third opening below the brewer, wherein the brewer is positioned laterally relative to the grinder. The capsule dock is configured to (a) hold a capsule containing a coffee filter and (b) translate the capsule from a first position under the second opening of the grinder to a second position under the third opening below the brewer. The controller is configured to control the grinder, brewer, and capsule dock.
