Solution Overview

Problem

Existing air cargo containers made from metals or fiberglass lack the lightweight, impact-resistant, and fire-resistant properties required for safe and efficient air transport, and their straight planar side panels are prone to damage during handling and impact.

Innovation Solution

The use of carbon fiber panels with convex shapes and a frame structure, combined with a retaining bag system and collapsible design, enhances impact resistance and fire safety while reducing weight and improving handling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If air cargo containers are made from metals or fiberglass, then structural strength is provided, but weight is excessive and impact resistance is insufficient

Engineering Contradiction:

Improvestructural strengthVSAvoidcontainer weight

Core Design Contradiction:

StrengthVSWeight of moving object

Solution Approach 1:

The patent applies composite materials by combining carbon fiber reinforced polymer panels with convex geometric structures. The carbon fiber composite provides high strength-to-weight ratio, while the convex geometry adds impact resistance. This resolves the contradiction by achieving both structural strength and weight reduction simultaneously through the synergistic combination of material properties and geometric design.

Inventive Principle:

Principle #40Composite materials

2Ease of manufacture

If straight planar side panels are used, then manufacturing is simplified, but impact resistance deteriorates during handling

Engineering Contradiction:

Improvepanel fabricationVSAvoidimpact resistance

Core Design Contradiction:

Ease of manufactureVSStrength

Solution Approach 1:

The patent implements curvature by designing convex geometric side panels instead of straight planar panels. The convex curvature distributes impact forces across a larger surface area and prevents stress concentration at corners, significantly improving impact resistance during handling while remaining manufacturable through conventional composite forming processes.

Inventive Principle:

Principle #14Spheroidality (Curvature)

3Strength

If conventional container designs are used, then structural integrity is maintained, but fire safety is insufficient at high temperatures

Engineering Contradiction:

Improvestructural integrityVSAvoidfire safety

Core Design Contradiction:

StrengthVSObject-affected harmful factors

Solution Approach 1:

The patent addresses fire safety by selecting carbon fiber reinforced polymer materials with specific thermal stability parameters capable of withstanding temperatures up to 1500°F. The material composition and structural design are optimized to maintain structural integrity under thermal stress, resolving the contradiction between maintaining strength and resisting fire hazards through parameter optimization of the composite material system.

AI summary

The present invention is directed to an air cargo container formed from a plurality of fiber-reinforced (e.g., carbon fiber) composite panels. The use of fiber reinforcement provides for an increased strength-to-weight ratio as compared to existing air cargo containers. Furthermore, the present invention also includes air cargo containers having convex side panels, which decreases the chance of damage to the container or to its contents in the event of an impact. The air cargo container is collapsible, with panels able to be stacked for more efficient storage.
