Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Collapsible fluid containers often collapse prematurely, trapping fluid and preventing its withdrawal, especially when dispensing expensive or critical fluids.

Innovation Solution

A collapsible bottle design featuring two interconnected tubular compartments with a non-collapsible shunt channelway that maintains communication with the outlet opening, ensuring fluid can be withdrawn even as the compartments collapse.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a single collapsible compartment is used, then the container structure is simple, but the container collapses prematurely and traps fluid preventing withdrawal

Engineering Contradiction:

Improvecontainer structureVSAvoidfluid withdrawal capability

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The container is divided into multiple collapsible compartments (first and second compartments) that can collapse independently. Each compartment has its own collapsible walls, allowing fluid to be withdrawn from one compartment even when another has collapsed, preventing fluid trapping and maintaining reliable dispensing capability.

Inventive Principle:

Principle #1Segmentation

2Ease of operation

If collapsible walls are provided to facilitate collapse, then the container can collapse upon itself, but the container may collapse at intermediate portions trapping fluid

Engineering Contradiction:

Improvecollapse functionVSAvoidfluid dispensing continuity

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The container is segmented into multiple collapsible compartments with independent collapsible walls. This segmentation ensures that if one compartment collapses at an intermediate portion, other compartments remain functional and can continue to dispense fluid, maintaining dispensing continuity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

A non-collapsible outlet conduit acts as an intermediary structure that maintains a permanent fluid passage from the compartments to the outlet. This conduit does not collapse with the compartments, ensuring continuous fluid dispensing capability even when compartments have collapsed.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Reliability

If multiple collapsible compartments are used, then fluid trapping is prevented, but the device complexity increases

Engineering Contradiction:

Improvefluid withdrawal capabilityVSAvoidcontainer structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The container is divided into multiple collapsible compartments that can be configured in various arrangements (side-by-side, stacked, etc.). This segmentation provides redundancy against fluid trapping while maintaining a relatively simple overall structure through the use of shared walls and a common non-collapsible outlet conduit.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The collapsible compartments serve multiple functions: they provide fluid storage capacity and simultaneously act as collapse-resistant structures through their interconnection. The shared walls between compartments provide structural support while allowing independent collapse of each compartment, reducing the need for additional complex components.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A collapsible bottle having at least two independent compartments each connected to provide communication with each other and, preferably, with a non-collapsible channelway leading to an outlet opening for the bottle.
