Solution Overview

Problem

Existing containment solutions for liquid-filled industrial objects are inadequate in preventing leaks during handling, transport, and storage, particularly due to the lack of flexibility, rigidity, and effectiveness in containing and holding liquids.

Innovation Solution

A flexible containment tray made of liquid-impermeable fabric with rigid inserts and a duffel top, featuring straps and fold lines for easy storage and transport, which maintains an open position to receive and secure liquid-filled objects, and includes an absorbent pad to manage spills.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a rigid containment tray is used, then leak prevention capability is improved, but storage space efficiency deteriorates

Engineering Contradiction:

Improveleak prevention capabilityVSAvoidstorage space efficiency

Core Design Contradiction:

ReliabilityVSVolume of moving object

Solution Approach 1:

The containment tray employs collapsible side walls that can transition between extended and retracted positions. When extended, the side walls provide rigid containment for leak prevention. When retracted, the tray collapses to a compact form for efficient storage and transport, resolving the contradiction between maintaining rigidity for leak prevention and reducing volume for storage efficiency

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The containment tray is divided into modular components including collapsible side walls, a base, and removable inserts. This segmentation allows the side walls to be collapsed independently for compact storage while maintaining the structural integrity of the base for leak containment, enabling the tray to switch between rigid containment mode and compact storage mode

Inventive Principle:

Principle #1Segmentation

2Volume of moving object

If a collapsible containment tray is used, then storage efficiency is improved, but structural rigidity deteriorates

Engineering Contradiction:

Improvestorage efficiencyVSAvoidstructural rigidity

Core Design Contradiction:

Volume of moving objectVSStrength

Solution Approach 1:

The collapsible side walls are designed with dynamic structural properties that allow them to transition between flexible collapsed states and rigid extended states. When extended to contain objects, the side walls achieve sufficient structural rigidity through their geometric configuration and material properties, while maintaining the ability to collapse for efficient storage

Inventive Principle:

Principle #15Dynamics

3Adaptability or versatility

If a flexible containment solution is used, then adaptability is improved, but liquid containment effectiveness deteriorates

Engineering Contradiction:

ImproveadaptabilityVSAvoidliquid containment effectiveness

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The containment tray utilizes flexible side walls made of liquid-impermeable materials that can adapt to different object shapes and sizes while maintaining effective liquid containment. The flexible materials are specifically selected to be both adaptable in form and impermeable to liquids, resolving the contradiction between adaptability and containment effectiveness

Inventive Principle:

Principle #30Flexible shells and thin films

Solution Approach 2:

The containment tray employs composite construction combining flexible outer materials with rigid structural inserts and liquid-impermeable barriers. This composite approach allows the side walls to be flexible and adaptable in shape while incorporating rigid elements and impermeable layers that ensure effective liquid containment

Inventive Principle:

Principle #40Composite materials

4Stability of the object's composition

If rigid structural inserts are added, then structural stability is improved, but device complexity increases

Engineering Contradiction:

Improvestructural stabilityVSAvoiddevice complexity

Core Design Contradiction:

Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The rigid structural inserts are designed as removable and separable components that can be independently assembled and disassembled. This segmentation allows the inserts to provide structural stability when needed while enabling easy removal and storage, reducing the overall device complexity and making the containment tray easier to maintain and transport

Inventive Principle:

Principle #1Segmentation
