Single-serving coffee pod and single-serving beverage brewer 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 of various coffee varieties and resulting in a difference in quality between boutique café and home-brewed coffee.
Innovation Solution
A single-serving coffee pod system with a hollow capsule holding whole coffee beans and an identification tag that, when scanned, provides information for the brewer to adjust grinding and brewing conditions, allowing for customizable brewing recipes, including grind size, brewing temperature, coffee-to-water ratio, and pouring patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If fixed brewing settings are used in capsule machines, then device complexity is reduced and ease of operation is improved, but brewing quality and flavor extraction are limited
Solution Approach 1:
The system automatically retrieves brewing parameters from the identification tag on the pod without requiring user input. The processor reads the tag information and automatically configures the brewing settings, allowing the system to serve itself while maintaining full customization capability.
Solution Approach 2:
The identification tag provides feedback information about the pod contents (coffee type, roast level, recommended parameters) to the brewer's processor. This feedback loop enables the system to automatically adjust brewing parameters based on the specific pod being used, resolving the contradiction between ease of operation and brewing customization.
2Productivity
If pre-ground coffee is used in capsules, then brewing speed is improved and convenience is enhanced, but coffee freshness and flavor quality deteriorate
Solution Approach 1:
The system performs the grinding action immediately before brewing based on the identification tag information. The processor receives the tag data, determines the appropriate grind size, and activates the grinder to prepare fresh grounds right before water contact, preserving freshness while maintaining brewing speed.
Solution Approach 2:
The system dynamically adjusts the grinding process based on real-time information from the identification tag. The grinder operates only when needed, and the grind parameters are dynamically configured according to the specific coffee type detected, ensuring optimal freshness and flavor extraction for each brewing cycle.
3Ease of manufacture
If basic brewing parameters are used, then device complexity is reduced and manufacturing cost is lowered, but brewing precision and coffee quality are limited
Solution Approach 1:
The identification tag acts as an intermediary carrier that stores precise brewing parameter information. Instead of embedding complex control mechanisms in the brewer, the system uses the tag as a mediator to provide precise parameters (grind size, temperature, pressure, timing) that guide the brewing process, achieving high precision without proportionally increasing manufacturing complexity.
Solution Approach 2:
The system replaces mechanical adjustment mechanisms with an information-based approach. The identification tag contains encoded brewing parameters that are read by the processor, which then automatically configures the brewing system. This substitution of mechanical complexity with information processing achieves precise brewing control while keeping the physical device relatively simple.

AI summary
A single-serving coffee pod includes: a hollow capsule having an opening at a first end thereof and at least one smaller opening in a second end thereof opposite the first end; a filter disposed within the capsule; a plurality of whole coffee beans located within the capsule; and a removable covering disposed over the opening of the capsule.
