Solution Overview

Problem

The transportation of fine artworks via air transport poses risks due to the use of custom wooden crates, which are environmentally unfriendly, economically disadvantageous, and contribute to waste, as they are often not reusable and can cause increased carbon emissions and handling damages.

Innovation Solution

A container assembly designed for industry-standard Unit Load Devices (ULDs) made from long-lasting, recyclable materials, featuring a modular structure with airbag assemblies and foam for shock absorption, allowing for secure and efficient loading and unloading, reducing the need for custom wooden crates.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If custom wooden crates are used to secure artworks, then the artworks are protected during transport, but the crates add considerable weight, increase fuel consumption and carbon emissions

Engineering Contradiction:
Improveartwork protectionVSAvoidcrate weight
Core Design Contradiction:
ReliabilityVSWeight of moving object

Solution Approach 1:

The invention divides the protective function into two separate components: a reusable rigid container framework and disposable shock-absorbing packaging materials. The rigid container provides structural protection and security, while the shock absorption function is handled by separate inflatable air bags and foam materials that can be removed and replaced. This segmentation allows the heavy wooden crate structure to be eliminated in favor of lighter materials that achieve the same protective effect.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention changes the physical state and properties of the packaging materials from solid wooden structures to inflatable air bags and foam materials. The air bags can be inflated to provide cushioning and then deflated for storage, while the foam materials provide shock absorption with significantly reduced weight compared to wood. This parameter change from solid rigid structures to inflatable and flexible materials resolves the contradiction between protection and weight.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If custom wooden crates are fabricated for each artwork, then the artworks are securely contained, but the crates cannot be reused and contribute to landfill waste

Engineering Contradiction:
Improveartwork containmentVSAvoidcrate waste
Core Design Contradiction:
ReliabilityVSLoss of substance

Solution Approach 1:

The invention separates the permanent reusable container from the temporary disposable packaging materials. The rigid container serves as a durable framework that can be reused indefinitely, while the shock-absorbing air bags and foam materials are designed to be removed, replaced, and disposed of after use. This segmentation enables the containment function to be maintained while eliminating the waste problem associated with disposable wooden crates.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention implements a system where the rigid container is recovered and reused for subsequent shipments, while the shock-absorbing air bags and foam materials are discarded after use. The container can be emptied, cleaned, and prepared for the next artwork, while the packaging materials are removed and disposed of. This recovering and reusing of the main container structure eliminates the need to discard the entire crate after a single use.

Inventive Principle:
Principle #34Discarding and recovering

3Reliability

If custom wooden crates are used, then the artworks are protected from handling damage, but the crates add fabrication costs and storage requirements

Engineering Contradiction:
Improveartwork protection from handlingVSAvoidcrate fabrication cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The rigid container is designed as a universal framework that can accommodate multiple different artworks through the use of adjustable shelving, removable dividers, and customizable interior configurations. Rather than fabricating a unique wooden crate for each artwork, the same container can be reused with different packaging materials and internal arrangements to protect various types of artworks. This universality eliminates the need for custom fabrication of individual crates.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The invention changes from solid wooden construction to a hybrid structure combining rigid framework with inflatable and foam materials. The rigid container provides structural integrity and security, while the shock absorption function is achieved through inflatable air bags and foam that can be adjusted for different artwork sizes and shapes. This parameter change reduces fabrication complexity and cost while maintaining protective capabilities.

Inventive Principle:
Principle #35Parameter changes

4Reliability

If traditional crating methods are used, then the artworks are secured, but the loading and unloading processes are time-consuming and complex

Engineering Contradiction:
Improveartwork securityVSAvoidloading and unloading time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The rigid container is pre-assembled and prepared before the artwork is placed inside. The container framework is ready with pre-attached air bags and foam materials positioned to provide optimal protection. This preliminary preparation of the container and packaging system eliminates the need for time-consuming on-site assembly and securing operations during loading and unloading, as the protective structure is already in place before the artwork is inserted.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The invention uses inflatable air bags that can be rapidly inflated and deflated to secure and release the artwork. The air bags provide dynamic adjustment capability, allowing quick securing of the artwork during loading and rapid release during unloading. This dynamic system is much faster than traditional mechanical fastening methods, reducing the time required for loading and unloading operations while maintaining secure artwork containment.

Inventive Principle:
Principle #15Dynamics

AI summary

A container assembly configured for loading into/onto a Unit Load Device (ULD) generally includes first and second containers. Rearward sides of the first and second containers include a securing catchment assembly for mating and securing the first and second containers. Frontward sides of the first and second containers each include a plurality of female/male door securing assemblies that complementarily mate with male/female door securing assemblies of a door assembly. When the first and second containers are mated, the container assembly defines an outer perimeter that is smaller than an inner perimeter of the ULD. The outer perimeter of the container assembly has a shape generally conforming with the shape of the inner perimeter of the ULD. One or more shock absorption assemblies/airbag assemblies configured to reduce vibration and movement of the container assembly are disposable between one or more walls of the ULD and the first and second containers/container assembly.
