Innovation Solution

The introduction of lightweight, movable bulkheads with strap harnesses and retaining tracks, featuring restorable breakaway straps, wing lip seals, and ergonomic handles, allowing for easy installation and secure partitioning of the cargo area into compartments with adjustable environmental conditions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If manual bulkheads are used to divide cargo areas, then compartments with different temperature ranges can be created, but the bulkheads are cumbersome to maneuver and secure, requiring significant manual labor

Engineering Contradiction:

Improvecompartimentation capabilityVSAvoidbulkhead maneuverability

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The bulkhead is divided into multiple panels that can be folded relative to each other, allowing the structure to be segmented for easier handling and deployment within the cargo area

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The bulkhead transitions from a static rigid structure to a dynamic foldable structure with movable joints, enabling easy repositioning and adaptation to different cargo configurations

Inventive Principle:

Principle #15Dynamics

2Reliability

If traditional securing mechanisms are used for bulkheads, then bulkheads can be held in place during transport, but the securing process is time-consuming and complex

Engineering Contradiction:

Improvebulkhead securingVSAvoidsecuring time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

Straps are pre-attached to the bulkhead panels and tracks are pre-installed in the cargo area, so that securing simply requires connecting pre-prepared elements rather than assembling components during loading

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The strap system is designed to be self-tensioning and self-securing, eliminating the need for complex mechanical fasteners or multiple workers to secure the bulkhead

Inventive Principle:

Principle #25Self-service

3Stability of the object's composition

If rigid bulkhead structures are used to maintain structural integrity, then compartments remain stable, but damage occurs during loading and unloading operations

Engineering Contradiction:

Improvestructural integrityVSAvoidimpact damage

Core Design Contradiction:

Stability of the object's compositionVSObject-affected harmful factors

Solution Approach 1:

The foldable joint design allows the bulkhead to flex and absorb impact forces during loading operations, preventing the rigid structure from transmitting damaging forces to the cargo or surrounding areas

Inventive Principle:

Principle #15Dynamics

4Reliability

If multiple straps are used to secure bulkheads at multiple points, then securing reliability is improved, but the device complexity increases

Engineering Contradiction:

Improvesecuring reliabilityVSAvoidstrap harness complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

A single strap system serves multiple functions: it attaches multiple panels together, secures the entire bulkhead assembly to the cargo area, and provides tensioning across multiple points simultaneously, eliminating the need for separate fasteners at each location

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

Example bulkheads for enclosed cargo transporters (e.g., trailers, trucks, reefers, and containers) are disclosed. An example bulkhead includes a first panel and a second panel adjoining the first panel to define a partition that includes a first lateral edge along the first panel and a second lateral edge along the second panel. The partition has a partition width extending from the first lateral edge to the second lateral edge. A harness is structured to extend beyond the partition width. The harness includes a breakaway fastener assembly that renders the bulkhead in an operative configuration and a restorable breakaway configuration. The breakaway fastener assembly is to couple to the partition when the bulkhead is in the operative configuration, and the breakaway fastener assembly to decouple from the partition when the bulkhead is in the restorable breakaway configuration.
