Collapsible Axial Joint Structure for Portable EOD Tool Stands
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current EOD equipment stands are expensive, bulky, and require tools for assembly, making them unsuitable for dismounted missions where they need to be lightweight, compact, and easily transportable, especially for handling unstable or unknown explosive devices.
Innovation Solution
A collapsible joint made from a pattern of punched or cut-out holes in a flat piece that forms a three-dimensional lattice framework without the need for tools, allowing different tubes or rods to pass through, enabling the creation of scalable, low-cost stands for various EOD tools and equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional EOD stands are used, then structural strength and stability are improved, but weight and bulk increase making them unsuitable for dismounted missions
Solution Approach 1:
The stand is divided into multiple telescopic segments that can slide relative to each other. Each segment is a separate component that can be independently adjusted, allowing the stand to be collapsed to a compact size for transport and extended to provide adequate support strength during use. This segmentation enables the stand to achieve both lightweight portability and structural strength when deployed.
2Stability of the object's composition
If traditional EOD stands are used, then structural stability is improved, but device complexity and assembly requirements increase
Solution Approach 1:
The telescopic stand incorporates self-locking mechanisms that automatically engage when segments are extended to the desired length. The segments lock into place without requiring tools or complex assembly procedures, allowing the technician to quickly set up the stand while maintaining stability. This self-service feature eliminates the need for specialized assembly tools and reduces the time required to deploy the stand.
3Force
If traditional EOD stands are used, then load-bearing capacity is improved, but adaptability to different tools decreases
Solution Approach 1:
The stand features adjustable telescopic segments that can be extended or retracted to different lengths, allowing the structure to be dynamically reconfigured for different tool sizes and weights. The adjustable height and configuration enable the same stand to accommodate various EOD tools from small disruptors to larger equipment, providing both load-bearing capacity and versatility through dynamic adaptation.
4Strength
If traditional EOD stands are used, then structural integrity is improved, but ease of transport and storage worsens
Solution Approach 1:
The telescopic segments are designed to nest within each other when collapsed, similar to nested dolls. The smaller segments fit inside larger segments, creating a compact bundled configuration that minimizes storage volume and facilitates transport. When deployed, the segments extend outward to provide the necessary structural integrity and support, effectively transitioning from a compact nested state to a fully extended load-bearing structure.

AI summary
An exemplary axial joint includes a planar member having a first plurality of joined sections and a second plurality of joined sections perpendicular to the first plurality of joined sections. Each section of the first plurality of joined sections and the second plurality of joined sections has a pattern of apertures therein, and each section is foldable approximately perpendicular to an adjacent section. The pattern of apertures in a first section after folding is congruent with the pattern of apertures in a second section after folding, wherein the second section is parallel to the first section, after folding. An elongate member is arranged through the apertures of one or more sections of the planar member, after folding the sections of the planar member.
