Solution Overview

Problem

Existing industrial packages for transporting radioactive materials fail to meet the distinct packaging requirements for different modes of transport, such as roadway, rail, air, and sea, and do not ensure compliance with multiple regulatory standards, including Department of Transportation (DOT) Class 7, International Air Transport Association (IATA), and International Maritime Dangerous Goods (IMDG) codes.

Innovation Solution

The development of industrial packages that integrate features like integrated bumpers, specialized bottom tube skids, lid lattice support, multiple gasket pressurization seals, corner reinforcement, modular interior components, and pressurization valves and filters to ensure compliance with DOT Class 7, IATA, and IMDG regulations, providing robust and secure containment for radioactive materials across various transport modes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If industrial packages are designed to meet only DOT Class 7 requirements for ground transport, then they satisfy regulatory requirements for roadway and rail transport, but they fail to comply with IATA and IMDG codes for air and sea transport

Engineering Contradiction:
Improvecompliance with multiple transport regulationsVSAvoidpackaging design complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The industrial package is designed with multi-functional features that satisfy multiple regulatory standards simultaneously. The package incorporates pressurization capability, multiple sealing systems, and structural reinforcements that meet the requirements of DOT Class 7, IATA, and IMDG codes, allowing a single package design to be used across different transport modes without repackaging or recertification

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

2Reliability

If industrial packages use simple sealing mechanisms, then they are easier to manufacture and operate, but they fail to maintain internal pressure and ensure regulatory compliance during transport

Engineering Contradiction:
Improvepressure containment capabilityVSAvoidsealing mechanism complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The package incorporates pre-installed pressurization valves and multiple gasket seals that are prepared in advance to maintain internal pressure. The sealing system includes gaskets positioned at critical interfaces, and the pressurization valves are pre-configured to equalize pressure differentials, ensuring reliability without requiring complex operational procedures during transport

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The sealing mechanism combines multiple gaskets, pressurization valves, and filter elements into an integrated system. The gaskets seal between the lid and body, while the pressurization valves and filters work together to maintain pressure equality and prevent contamination, creating a unified sealing system that ensures both simplicity and reliability

Inventive Principle:
Principle #5Merging (Combining)

3Strength

If industrial packages lack structural reinforcements, then they are lighter and easier to manufacture, but they fail to pass stacking, penetration, and free drop tests required by regulations

Engineering Contradiction:
Improvestructural integrityVSAvoidpackage weight
Core Design Contradiction:
StrengthVSWeight of moving object

Solution Approach 1:

The package incorporates localized structural reinforcements at critical stress points rather than uniformly strengthening the entire structure. Integrated bumpers are positioned at corners and edges to absorb impact, the lid lattice support is strategically placed to prevent lid deformation during stacking, and corner reinforcements are added only where needed to pass penetration and free drop tests, minimizing weight increase while maximizing structural integrity

Inventive Principle:
Principle #3Local quality
