Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional beverage containers require significant workload and cost for managing their internal state due to direct contact with beverages, and existing solutions like dispense heads increase complexity and cost.

Innovation Solution

A replaceable component for beverage containers comprising a tubular member and a bag that can be easily attached to a beverage extraction pipe, allowing for easy attachment and detachment, with the tubular member sliding along the pipe's longitudinal direction and forming an annular contact to contain beverages.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of stationary object

If a fitting is fixed to the mouth portion of a beverage storage container using threaded engagement, then the beverage container can be reused, but the workload and cost required for managing the internal state of the beverage storage container are large

Engineering Contradiction:

Improvereusability of beverage containerVSAvoidworkload for managing internal state

Core Design Contradiction:

Duration of action of stationary objectVSEase of operation

Solution Approach 1:

The beverage container system is divided into a reusable outer container and a replaceable inner bag. The bag can be detached and replaced independently without affecting the container structure, allowing easy management of the internal state while maintaining container reusability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The bag containing the beverage is extracted as a separate replaceable component from the beverage storage container. This allows the internal state (beverage type, freshness) to be easily changed by simply replacing the bag, reducing the workload for managing the container's internal state.

Inventive Principle:

Principle #2Taking out (Extraction)

2Reliability

If a dispense head is used to prevent beverage contact with the container, then beverage quality is maintained, but device complexity and cost increase

Engineering Contradiction:

Improvebeverage quality maintenanceVSAvoidcomplexity of beverage extraction system

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The bag is designed as a disposable or easily replaceable component that prevents beverage contact with the reusable container. This simple approach maintains beverage quality without requiring complex dispense heads or extraction mechanisms.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The bag acts as a flexible barrier between the beverage and the rigid container structure. This simple film-based solution effectively isolates the beverage from the container while avoiding the need for complex mechanical extraction systems.

Inventive Principle:

Principle #30Flexible shells and thin films

3Ease of operation

If a tubular member is made slidable along the beverage extraction pipe, then attachment and detachment become easy, but the structure becomes more complex

Engineering Contradiction:

Improveease of attachment and detachmentVSAvoidcomplexity of tubular member structure

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The tubular member is designed with sliding capability along the beverage extraction pipe, transitioning from a static to a dynamic connection. This allows easy attachment and detachment through simple sliding motions without requiring complex fastening or unfastening mechanisms.

Inventive Principle:

Principle #15Dynamics
