Problem

Existing beverage preparation machines using cartridges, such as coffee capsules, are limited in preparing complex and individualized beverages without increasing complexity and usability issues, as they typically only allow for uniform beverages.

Innovation Solution

A beverage preparation machine with two independently controllable liquid supply circuits and a network interface, allowing for the preparation of composite beverages by combining flavor-containing and hot water components, controlled via an external electronic device for enhanced user convenience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a single liquid supply circuit is used to prepare beverages, then the device complexity is low and ease of operation is high, but the adaptability to prepare complex beverages is limited

Engineering Contradiction:
Improveability to prepare complex beveragesVSAvoidcomplexity of liquid supply system
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The liquid supply system is divided into two independent circuits: a first liquid supply circuit that delivers liquid to the cartridge for beverage preparation, and a second liquid supply circuit that delivers liquid directly to the beverage outlet. This segmentation enables the machine to prepare complex beverages by combining outputs from both circuits while maintaining manageable system complexity through modular independence.

Inventive Principle:
Principle #1Segmentation

2Manufacturing precision

If individual control of liquid circuits is implemented, then the precision of beverage customization is improved, but the device complexity increases requiring complex user interface

Engineering Contradiction:
Improveprecision of liquid volume and temperature controlVSAvoidcomplexity of control system
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

A control unit acts as an intermediary between the two liquid supply circuits, coordinating their operation to deliver precise liquid volumes and temperatures. The control unit manages the complexity internally, allowing individual circuit control without requiring a complex user interface, as the control unit automatically coordinates the intricate control parameters.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If a complex user interface is provided on the machine for individual control, then the adaptability for personalized beverages is improved, but the ease of operation deteriorates

Engineering Contradiction:
Improvepersonalization capabilityVSAvoiduser convenience
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The complex control interface is extracted from the beverage preparation machine and placed on an external electronic device. This allows the machine to maintain simplicity and ease of operation while still providing advanced personalization capabilities through the external device's interface, which handles all complex control parameters for individualized beverage preparation.

Inventive Principle:
Principle #2Taking out (Extraction)

4Ease of operation

If remote control via external device is implemented, then the ease of operation is improved by simplifying machine interface, but the loss of direct control information occurs

Engineering Contradiction:
Improvesimplicity of machine interfaceVSAvoidcontrol information transmission
Core Design Contradiction:
Ease of operationVSLoss of information

Solution Approach 1:

The direct mechanical control interface on the machine is replaced with wireless electronic communication between the external device and the machine. This substitution transmits all necessary control information (liquid volumes, temperatures, timing) digitally through the network interface, eliminating information loss by using comprehensive digital data transmission instead of simplified mechanical controls.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
