Modular EOD Disruption System With Interchangeable Chambers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing disruption systems for Explosive Ordnance Disposal (EOD) are limited to a single ammunition caliber, requiring multiple systems and geometry changes for different calibers, which complicates field operations and increases the need for multiple devices and new equipment.
Innovation Solution
A modular disruption system with interchangeable barrel and chamber sections, allowing for different calibers and geometries, enabling a single system to support multiple ammunition types without requiring barrel bore changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a disruption system is designed to fire a single caliber of projectile, then the internal geometry (chamber throat geometry) can be optimized for that specific caliber, but the system cannot support multiple ammunition calibers and requires multiple different disruption systems for different calibers
Solution Approach 1:
The disruption system is divided into separable components: a barrel assembly and a chamber assembly. The chamber assembly can be detached and replaced independently from the barrel assembly, allowing different chamber geometries to be matched with different projectile calibers while maintaining a consistent barrel interface. This segmentation enables multi-caliber support without requiring complete system replacement.
Solution Approach 2:
The barrel assembly is designed with a universal interface that can accommodate multiple chamber assemblies with different throat geometries. The breech portion and barrel bore are configured to work with various chamber designs, allowing a single barrel assembly to support multiple ammunition calibers through interchangeable chamber components.
2Adaptability or versatility
If the chamber throat geometry is changed to support a different caliber, then the disruption system can accommodate new ammunition types, but the barrel bore geometry must also be changed, requiring new disruption systems
Solution Approach 1:
The system separates the chamber assembly from the barrel assembly, allowing the chamber to be modified for different calibers without requiring barrel bore changes. The chamber assembly including the throat geometry can be independently manufactured and replaced, while the barrel assembly remains unchanged.
Solution Approach 2:
The chamber assembly acts as an intermediary component between the breech and the barrel bore. By modifying the chamber assembly rather than the barrel bore directly, the system can adapt to different ammunition types while preserving the original barrel geometry and avoiding complex barrel modifications.
3Reliability
If multiple disruption systems are carried for different calibers, then each system can be optimized for its specific caliber, but the weight and complexity of field operations increase
Solution Approach 1:
By making the chamber assembly detachable, the system allows field operators to swap only the chamber component rather than carrying multiple complete disruption systems. The heavy barrel and stock components are retained, and only the lighter chamber sections need to be exchanged to accommodate different calibers.
Solution Approach 2:
Multiple chamber assemblies for different calibers can be combined into a single disruption system platform. Instead of carrying separate complete systems, operators can attach different chamber sections to the same barrel assembly, effectively merging multiple caliber capabilities into one physical system.
