Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional cargo restraint systems are used, then cargo can be secured, but the systems are inefficient, costly, and fail to securely hold loads during transportation
Solution Approach 1:
The restraint system uses a composite structure combining wooden dunnage elements with metal binding straps and chains. This composite approach leverages the compressive strength of wood for load distribution and the tensile strength of metal components for active restraint, creating a more reliable securement system that prevents cargo shift while maintaining transport efficiency
Solution Approach 2:
The restraint system is divided into functional segments: wooden dunnage for load distribution and cushioning, metal binding straps for circumferential restraint, and chains for diagonal securing. This segmentation allows each component to perform its specific function optimally, improving overall securement reliability without requiring a single complex device
2Reliability
If conventional restraint systems are used, then cargo can be secured, but labor requirements are excessive
Solution Approach 1:
Wooden dunnage elements are pre-positioned against the cargo before the container is closed, creating a preliminary restraint structure that distributes load and prevents initial movement. This preliminary action reduces the complexity and time required for final securement operations
Solution Approach 2:
The wooden dunnage structure is designed to automatically distribute cargo weight and prevent shift without requiring continuous active restraint. The system serves itself by using the cargo's own weight against the dunnage to maintain securement, reducing the need for additional labor-intensive adjustments
3Reliability
If conventional restraint systems are used, then cargo can be secured, but compliance with regulations is difficult to achieve
Solution Approach 1:
The restraint system separates compliance functions into distinct components: wooden dunnage for load distribution and impact absorption, metal straps for circumferential binding, and chains for diagonal securing. This segmentation makes it easier to verify and document compliance with different regulatory requirements for each function
Solution Approach 2:
The system uses standardized metal strap widths, chain link sizes, and wooden dunnage dimensions that can be selected based on specific regulatory requirements and cargo weights. This parameter-based approach allows the same basic system design to comply with different regulations by simply changing component specifications rather than redesigning the entire system
