Solution Overview

Problem

Existing beverage capsule technologies struggle to effectively extract essence from hygroscopic ingredients like tea leaves using pressurized liquid, as nonporous capsules prevent desirable extraction and result in instant tea beverages rather than authentic tea beverages.

Innovation Solution

A sealed, nonporous capsule construction that allows for the extraction of essence from hygroscopic ingredients by introducing pressurized liquid and using objects within the capsule to modify the flow rate and distribution of the liquid, ensuring even extraction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a nonporous capsule is used to protect hygroscopic ingredients from air and humidity, then ingredient freshness is improved, but liquid penetration and essence extraction are impeded

Engineering Contradiction:

Improveingredient freshnessVSAvoidessence extraction efficiency

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The capsule is divided into distinct functional zones: a nonporous sealed body for protection, and a porous insert or permeable region for liquid penetration. This segmentation allows different parts of the capsule to serve different functions - the nonporous portions protect ingredients while the porous portions enable extraction.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different regions of the capsule have different porosity properties. The capsule body maintains nonporous characteristics for protection, while specific localized areas (such as the insert or permeable zones) have porous properties that facilitate liquid penetration and essence extraction.

Inventive Principle:

Principle #3Local quality

2Speed

If pressurized liquid is introduced into a nonporous capsule, then extraction speed is improved, but ingredient alteration and spoilage are accelerated

Engineering Contradiction:

Improveextraction speedVSAvoidingredient spoilage

Core Design Contradiction:

SpeedVSObject-generated harmful factors

Solution Approach 1:

A porous insert or permeable intermediate structure is introduced as a mediator between the pressurized liquid and the hygroscopic ingredients. This intermediary controls the liquid-ingredient interaction, allowing extraction to proceed while preventing direct harmful effects of pressurization on the ingredients.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

Porous materials are used in the capsule insert or permeable regions to control liquid flow and interaction with ingredients. The porous structure allows liquid penetration for extraction while regulating the process to prevent ingredient alteration and spoilage that would occur with direct pressurization.

Inventive Principle:

Principle #31Porous materials

3Productivity

If a porous capsule is used to enable liquid penetration, then essence extraction is improved, but ingredient exposure to air and humidity increases

Engineering Contradiction:

Improveessence extraction efficiencyVSAvoidingredient exposure to elements

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The capsule is segmented into a nonporous sealed body and a porous insert. The nonporous body maintains protection from air and humidity, while the porous insert localized to extraction zones enables liquid penetration and essence extraction without compromising overall ingredient protection.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Porosity is applied locally only where needed for extraction (in the insert or permeable zones) rather than throughout the entire capsule. This localized porosity enables essence extraction while the majority of the capsule remains nonporous to protect ingredients from environmental exposure.

Inventive Principle:

Principle #3Local quality

AI summary

A capsule is disclosed that comprises a sealed body that encloses one or more cavities containing one or more substances including at least one hygroscopic substance and one or more objects within. Pressurized liquid is introduced into a cavity using a suitable device from one or more areas of the capsule body, to interact with the substance(s) within. The object(s) are configured to alter the characteristics of the flow of the liquid, particularly in contact with the hygroscopic substance(s). The liquid exits from one or more areas of the capsule body, having optimally extracted the essence of the substance(s) due to the altered flow rate, liquid exposure, flow distribution, and flow patterns.
