Modular Adjustable Load Stabilizer for Cargo
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cargo stabilization systems for transport containers are inefficient, costly, labor-intensive, and lack flexibility, often failing to effectively secure cargo against shifting forces during transport, especially in varying environments and with irregular shapes, and are not suitable for reuse or easy assembly with unskilled labor.
Innovation Solution
A modular, adjustable void filler system using extendible tubular members with a locking mechanism that can be easily assembled and disassembled, allowing for securement of cargo within transport containers by filling voids between cargo surfaces and internal walls, providing enhanced strength and flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional load containment systems (wood framing, steel strapping, heavy air bags) are used to stabilize cargo, then cargo stability is improved, but installation labor and time requirements increase significantly
Solution Approach 1:
The void filler is divided into multiple cylindrical segments that can be individually inserted and expanded within the void space. Each segment can be independently positioned and activated, allowing for simplified installation where workers simply insert the segments rather than assembling complex frameworks.
Solution Approach 2:
The void filler segments automatically expand and stabilize cargo through self-actuating mechanisms (such as spring expansion or inflatable elements) that require no manual adjustment or complex installation procedures. The system serves itself by automatically filling voids and securing cargo once inserted.
2Reliability
If custom-fabricated dunnage materials are used to secure irregularly shaped cargo, then cargo securement effectiveness is improved, but manufacturing cost and complexity increase
Solution Approach 1:
The cylindrical void filler segments are designed as universal components that can be used with various cargo shapes, sizes, and configurations. The same basic segment design can fill different void geometries through strategic placement and expansion, eliminating the need for custom-fabricated dunnage for each cargo type.
Solution Approach 2:
The void filler segments can change their effective parameters (volume, shape, density) through expansion mechanisms that allow a single compact component to transform into a space-filling structure adapted to the specific void geometry, providing custom-fit securement without custom manufacturing.
3Reliability
If heavy-duty air bags and rigid framing are used to prevent cargo movement, then cargo stability is improved, but transportability and storage efficiency of the stabilization system deteriorate
Solution Approach 1:
The cylindrical void filler segments are designed to nest within each other when not in use, with smaller segments fitting inside larger ones. This nesting capability dramatically reduces storage volume and improves transportability, allowing large quantities of stabilization components to be compactly stored and efficiently deployed when needed.
4Reliability
If traditional void fillers are used that cannot be reused, then initial cargo securement is achieved, but long-term cost efficiency and sustainability deteriorate
Solution Approach 1:
The void filler segments are designed to be recovered and reused after their initial function. The segments can be collapsed or disassembled from their expanded securement configuration, allowing them to be retrieved, inspected, and redeployed for subsequent cargo loads, eliminating the need to discard them after single use.

AI summary
A method and apparatus for stabilizing cargo within a transport container. First and second tubular elements are provided having generally cylindrical bodies and bearing members are mounted at a terminal end which can react against opposing surfaces within the transport container and stabilize cargo within the container. An extension mechanism allows for the extension and selective translation between the first and second tubular members allowing the apparatus to extend and fill the space between opposing surfaces within the transport container and stabilize the cargo. At least one of the tubular members is composed with two elongate halves. A method for stabilizing cargo within a transport container includes providing an extensible load stabilizer having first and second tubular elements, each having a bearing member. Forming at least one of the tubular members by mating together two tubular halves. The method further includes positioning the load stabilizer between opposing surfaces within the transport container and extending the tubular members with respect to each other, and stabilizing a surface of cargo against an opposing surface.
