Spherical Beverage Capsule for Orientation-Free Piercing

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing beverage capsules require precise positioning in machines for automatic preparation and dispensing, limiting their use in bulk storage and consecutive dispensing, especially in high-demand settings like bars and businesses, due to their design that bursts only at a specific weakness zone.

Innovation Solution

A spherical capsule with an air and water impermeable packaging envelope that can burst on any part of its surface under pressure, allowing for flexible positioning and piercing by the machine's device, enabling infusion and recovery of the beverage without pre-positioning, and featuring a filtering envelope for enhanced protection and quality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the capsule uses a packaging envelope that bursts only at a specific weakness zone, then the beverage quality is maintained through controlled infusion, but the capsule requires precise positioning in the machine, increasing device complexity and preventing bulk storage

Engineering Contradiction:

Improvebeverage qualityVSAvoidpositioning mechanism

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies asymmetry by creating a spherical capsule that intentionally lacks symmetric burst properties - the envelope is designed with a specific weakness zone that causes it to burst only in one direction. This asymmetric design ensures reliable beverage quality through controlled infusion while the spherical outer shape provides symmetric interface properties for simple machine interaction, resolving the contradiction between quality control and positioning complexity

Inventive Principle:

Principle #4Asymmetry

Solution Approach 2:

The patent segments the capsule into two functional parts: an outer spherical packaging envelope that provides the burst interface and maintains beverage quality, and an inner filtering envelope that handles the infusion process. This segmentation allows the outer envelope to be pierced in any orientation while the inner filtering envelope ensures proper beverage extraction, resolving the positioning complexity issue

Inventive Principle:

Principle #1Segmentation

2Reliability

If the capsule requires specific positioning with the top opposing the piercing device, then the infusion process is controlled, but automatic bulk storage and consecutive dispensing become impossible

Engineering Contradiction:

Improveinfusion controlVSAvoidconsecutive dispensing capability

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The spherical packaging envelope serves multiple functions: it maintains beverage quality through air and water impermeability, provides a universal interface that can be pierced from any direction, and enables bulk storage in reservoirs. The filtering envelope handles the infusion control function, separating the positioning requirement from the infusion control requirement, thereby enabling automatic consecutive dispensing

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Reliability

If the packaging envelope is air and water impermeable, then beverage storage quality is maintained, but the envelope cannot be easily pierced for infusion

Engineering Contradiction:

Improvebeverage storage qualityVSAvoidpiercing ease

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The patent applies local quality by creating a specific weakness zone in the otherwise air and water impermeable packaging envelope. This localized area has different properties (reduced thickness or structural integrity) that make it susceptible to bursting under pressure, while the rest of the envelope maintains its impermeable properties for beverage storage quality

Inventive Principle:

Principle #3Local quality

AI summary

Disclosed is a capsule designed to be used in an automatic beverage preparation and dispensing machine. The capsule includes a compacted aggregate of a substance to be infused; and a packaging envelope impermeable to air and water. The packaging envelope is configured to hold the compacted aggregate of the substance in the interior of the capsule so that infusion is carried out in the interior of the capsule. Also disclosed is a method comprising piercing the packaging envelope of the capsule, using a piercing device of an automatic beverage preparation and dispensing machine.
