Solution Overview

Problem

Beverage forming systems face challenges in accommodating cartridges of different sizes and shapes without requiring users to manipulate adapters or adjust the cartridge holder, leading to inefficient and inconvenient operation.

Innovation Solution

A cartridge holder with radially movable and compliant portions that adjust the size and shape of the opening to accommodate various cartridge sizes and shapes, including different rim diameters and irregular shapes, and can support cartridges at different locations for fluid inlet and outlet arrangements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the cartridge holder has a fixed opening size and shape, then the structure is simple and manufacturing is easy, but it cannot accommodate cartridges of different sizes and shapes

Engineering Contradiction:
Improveaccommodation of different cartridge sizes and shapesVSAvoidcartridge holder structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The cartridge holder incorporates radially movable portions that can dynamically adjust the opening size and shape to accommodate different cartridge dimensions. These portions move radially inward or outward depending on the cartridge size, transforming a static structure into a dynamic one that adapts to various cartridge configurations.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The opening parameters (size and shape) of the cartridge holder are made changeable through the radially movable portions. By altering the radial position of these portions, the holder can modify its opening characteristics to match different cartridge specifications, enabling versatility without requiring multiple dedicated holders.

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If the cartridge holder requires user manipulation of adapters or adjustment components, then it can accommodate different cartridges, but the ease of operation deteriorates

Engineering Contradiction:
Improveaccommodation of different cartridge sizes and shapesVSAvoidcartridge placement convenience
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The cartridge holder employs spring-loaded radially movable portions that automatically adjust to accommodate different cartridge sizes without user intervention. When a cartridge is inserted, the springs enable the movable portions to self-adjust their radial position, eliminating the need for users to manually manipulate adapters or adjustment mechanisms.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

Spring elements act as intermediaries between the inserted cartridge and the radially movable portions. These springs transmit the insertion force and enable smooth, automatic adjustment of the holder's opening, facilitating effortless accommodation of various cartridge types without direct user manipulation of complex mechanisms.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If the cartridge holder uses rigid structure, then manufacturing precision is easier to achieve, but it cannot adapt to different cartridge shapes without user adjustment

Engineering Contradiction:
Improveaccommodation of different cartridge rim shapesVSAvoidengagement portion structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The engagement portion incorporates flexible radially movable portions that can elastically deform to accommodate different cartridge rim shapes. These portions function similarly to flexible shells, allowing the structure to conform to various cartridge geometries while maintaining structural integrity, thereby achieving adaptability without complex rigid mechanisms.

Inventive Principle:
Principle #30Flexible shells and thin films

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 easy and convenient placement of differently sized and shaped cartridges, ensuring proper alignment and operation of inlet and outlet ports, enhancing user experience and machine versatility.

Implementation Method 1

The engagement portion may include one or more resilient portions that can move resiliently such that the act of placing a cartridge in the holder causes movement of the resilient portions and adjustment of the size and/or shape of the receiving opening.

AI summary

A method and apparatus for opening and closing a cartridge holder of a beverage forming machine. The cartridge holder may have an opening arranged to receive and hold a cartridge with the cartridge holder. The opening may be adjustable in size and/or shape to allow the cartridge holder to receive and engage with cartridges of different size and/or shape. The cartridge holder may include one or more movable portions that are adjustable in position to effectively adjust a size and/or shape of the opening.
