Solution Overview

Problem

Current single-serve beverage machines using pods face issues with inconsistent beverage quality due to uncontrolled extraction parameters and the difficulty in recognizing pod types, leading to incorrect settings and potential for counterfeit pods, making the machines complex to use and prone to inefficiencies and contamination.

Innovation Solution

Incorporating a recognition element on the pod's flange that can be recognized by the dispenser, allowing it to adjust parameters like water temperature, pressure, and infusion time based on the pod type and user preferences, and using a combination of optical, mechanical, or electrical recognition devices to ensure proper pod identification and prevent liquid absorption by the recognition element.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If a recognition element is added to the pod to enable automatic identification, then the beverage quality and parameter control are improved, but the pod structure and system complexity increase

Engineering Contradiction:
Improvebeverage quality controlVSAvoidpod structure
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent applies color-coded identification rings or patterns on the pod flange that correspond to different beverage types and extraction parameters. This visual recognition system allows the machine to identify pod types without complex electronic components, resolving the contradiction by improving parameter control while maintaining simple pod structure.

Inventive Principle:
Principle #32Color changes

Solution Approach 2:

The recognition element acts as an intermediary between the pod and the machine's control system. This mediator enables automatic parameter adjustment without requiring complex direct communication, thereby improving beverage quality control while adding minimal structural complexity to the pod.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Measurement precision

If the recognition device is placed in direct contact with the pod flange for identification, then the recognition accuracy is improved, but the risk of liquid absorption and contamination increases

Engineering Contradiction:
Improvepod identification accuracyVSAvoidliquid absorption and contamination
Core Design Contradiction:
Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The patent extracts the recognition element from the liquid-exposed flange area and places it on a protruding portion that extends beyond the liquid contact zone. This allows the recognition device to maintain direct contact with the pod for accurate identification while preventing liquid absorption and contamination of the recognition components.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The recognition element is positioned in a different spatial dimension (vertically above the flange on a protrusion) rather than on the flat flange surface. This dimensional change allows the recognition device to contact the pod for identification while remaining outside the liquid contact area, thus avoiding contamination.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Adaptability or versatility

If multiple commands and controls are provided for different pod types and parameters, then the adaptability and versatility of the machine are improved, but the ease of operation deteriorates

Engineering Contradiction:
Improvepod type compatibilityVSAvoiduser interface complexity
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent implements automatic recognition and parameter selection where the machine identifies the pod type through the recognition element and automatically configures the appropriate extraction parameters. This self-service approach eliminates the need for users to manually select commands for different pod types, thereby maintaining high adaptability while dramatically improving ease of operation.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The recognition system provides immediate feedback about the detected pod type, and the machine automatically adjusts parameters based on this feedback. This closed-loop system ensures versatile pod compatibility while keeping the user interface simple, as the machine handles parameter selection automatically based on recognition data.

Inventive Principle:
Principle #23Feedback
