Solution Overview

Problem

Beverage forming systems face challenges in accommodating cartridges of different sizes and shapes without requiring adapters or specific user configuration, and in efficiently directing fluid inflow and beverage outflow for various cartridge types.

Innovation Solution

A cartridge holder with movable components and adjustable openings that can accommodate cartridges of varying sizes and shapes, and a system with multiple inlet and outlet ports that adjust based on the cartridge type to ensure proper fluid interaction and beverage extraction, including detectors for cartridge authentication and fluid control.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a single fixed outlet port is used in the cartridge holder, then the device structure is simple, but it cannot accommodate cartridges of different sizes and shapes with different flow arrangements

Engineering Contradiction:
Improvecompatibility with different cartridge typesVSAvoidstructure of cartridge holder
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The outlet port is made movable relative to the cartridge holder, allowing it to be positioned in different locations (first position for upward flow, second position for downward flow) depending on the cartridge type being used. This dynamic repositioning enables a single outlet port to serve multiple cartridge configurations without requiring multiple fixed ports or complex switching mechanisms.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The outlet port is designed to perform multiple functions by being repositionable to different locations. It can receive beverage from cartridges with upward flow arrangement in the first position and from cartridges with downward flow arrangement in the second position, making a single component universal for different cartridge types.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If multiple fixed outlet ports are provided for different cartridge types, then all cartridge configurations can be accommodated, but the device structure becomes more complex

Engineering Contradiction:
Improvecompatibility with different cartridge typesVSAvoidnumber of outlet ports
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Instead of providing multiple fixed outlet ports simultaneously, the system uses a single outlet port that can be dynamically repositioned to the appropriate location based on the cartridge type. This eliminates the need for multiple permanent ports while maintaining compatibility with different cartridge configurations.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The invention extracts the location variability from the outlet port design by making the port itself movable rather than fixed at multiple locations. This separates the function of accommodating different positions from the structural complexity of having multiple fixed ports.

Inventive Principle:
Principle #2Taking out (Extraction)

3Adaptability or versatility

If the outlet port is made movable to accommodate different cartridges, then versatility is improved, but the control mechanism becomes more complex

Engineering Contradiction:
Improveaccommodation of different cartridge sizes and shapesVSAvoidmovable mechanism of outlet port
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The outlet port positioning mechanism is designed to be automatically actuated by the cartridge itself during insertion. The cartridge's size, shape, or features interact with the mechanism to move the outlet port to the correct position without requiring external control systems, sensors, or user intervention.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The outlet port is pre-positioned in a default location and the mechanism is designed so that the actuation action (moving the outlet port) occurs automatically as part of the cartridge insertion process itself, before the beverage flow begins.

Inventive Principle:
Principle #10Preliminary action

AI summary

A method and apparatus for controlling operation of a beverage forming machine arranged for use with cartridges of different types, or receiving an upwardly flowing beverage from a cartridge. A beverage outlet may be movable to receive beverage from a cartridge of a first type, and to not receive beverage from a cartridge of a second type. Different cartridge characteristics may be detected by multiple detectors, e.g., for detecting a presence/absence of a cartridge, a cartridge type and/or an authorization feature.
