Solution Overview

Problem

Existing beverage and food preparation systems require complex and specially designed cartridges to manage high pressures, and users must manually set or recognize preparation parameters, which can be cumbersome and inflexible.

Innovation Solution

A machine with a valve system that interacts with the cartridge collar to automatically adjust pressure based on the cartridge's geometry, allowing for variable pressure preparation without user intervention, using a piston and spring mechanism to open at predetermined pressures defined by the cartridge's design.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If complex specially designed cartridges are used to manage high pressures, then the desired quality of beverage/food product can be produced, but the device complexity and manufacturing cost increase

Engineering Contradiction:
Improvebeverage qualityVSAvoidcartridge design
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent introduces a collar as an intermediary component between the cartridge and the machine's valve system. This collar translates the cartridge's geometric features into pressure control signals for the valve, allowing pressure management without requiring the cartridge itself to be complex or specially designed for high pressure.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The cartridge's collar geometry automatically determines the preparation pressure through its interaction with the machine's valve means. The system self-regulates pressure based on the cartridge's own geometric features without requiring external control or complex cartridge design.

Inventive Principle:
Principle #25Self-service

2Adaptability or versatility

If preparation parameters are preselected by the operator, then the system can accommodate different products, but the ease of operation decreases

Engineering Contradiction:
Improveproduct varietyVSAvoiduser input required
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system automatically determines preparation parameters based on the cartridge's geometric features. The cartridge collar's geometry serves as an identifier that the machine's valve system uses to automatically select the appropriate pressure, eliminating the need for manual parameter selection while maintaining adaptability to different products.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent changes the physical parameter of the cartridge collar (geometric features) to encode preparation parameter information. The machine reads these geometric parameters and automatically adjusts the preparation pressure accordingly, replacing manual parameter selection with automated parameter detection.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If the cartridge internal geometry is designed to enable desired quality under high pressure, then beverage quality improves, but the manufacturing precision requirements increase

Engineering Contradiction:
Improvebeverage qualityVSAvoidcartridge geometry
Core Design Contradiction:
ReliabilityVSManufacturing precision

Solution Approach 1:

The collar acts as an intermediary that transfers the function of pressure determination from the complex internal cartridge geometry to a simpler external geometric feature. This external collar geometry is easier to manufacture with standard precision while achieving the same quality outcome through interaction with the machine's valve system.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

This disclosure relates to improvements in beverage/food product preparation systems and in particular to beverage/food product preparation systems comprising machines of the type which use pre-packaged cartridges containing beverage or food ingredients. The cartridge (30) contains one or more beverage or food ingredients for use in a machine for preparing a beverage or food product from said ingredients. The cartridge (30) comprises a base (34), an outlet aperture (37) in the base (34), and a collar (38) extending from the cartridge base (34) around the outlet aperture (37). The cartridge (30) is inserted into a holding receptacle (14) of a machine the collar (38) interacts with an element (65) of the machine and the collar (38) is configured to determine the pressure in the cartridge (30) during the preparation process.
