Destructive Charge Kit for Bomb Disposal Logistics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing destructive charges for non-contact ordnance disposal face challenges in precise on-site explosive metering, inhomogeneities leading to inconsistent penetration power, high logistics and monitoring efforts, and storage complexities.
Innovation Solution
A kit comprising separate non-safety-relevant components (tubular housing, hollow charge insert, and cap) for on-site assembly, using existing explosives and detonators, with a loading aid to ensure precise positioning and bubble-free explosive placement, and optional metal-free inserts for electronic warfare.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the destructive charge is stored and transported as a fully assembled charge, then the operational readiness is improved, but the logistics effort and monitoring effort increase significantly
Solution Approach 1:
The destructive charge is divided into separate components (housing element, shaped charge insert, cap, loading aid) that can be stored and transported independently. Only the non-safety-relevant components are segmented into the kit, while the explosives and detonators are added on-site. This segmentation reduces logistics complexity while maintaining operational readiness.
2Device complexity
If the explosive is metered on site, then the storage and transport complexity is reduced, but the penetration power precision deteriorates due to inhomogeneities such as bubbles
Solution Approach 1:
The loading aid is designed with integrated functions to perform preliminary actions during on-site assembly: it guides the shaped charge insert into precise axial positioning, defines the correct amount of explosive to be added, and provides a pressing function to compact the explosive uniformly. This preliminary preparation ensures consistent penetration power despite on-site metering.
Solution Approach 2:
The loading aid acts as an intermediary tool between the components and the final assembled charge. It mediates the positioning of the shaped charge insert, controls the explosive filling process, and ensures uniform compaction. This intermediary device bridges the gap between simple on-site assembly and precise manufacturing requirements.
3Ease of operation
If manual tamping is used to compress the explosive, then the assembly simplicity is improved, but the penetration power consistency deteriorates due to operator variability
Solution Approach 1:
The loading aid serves as a mechanical intermediary that standardizes the compaction process. Its pressing surface and structural design ensure that the explosive is compressed uniformly regardless of operator technique. This intermediary device eliminates operator variability while maintaining the simplicity of manual assembly.

Function Achieved in This Case
Significantly reduces logistics and monitoring costs, ensures reproducible penetration performance, and minimizes storage and transport risks with reduced assembly complexity and no expiry periods.
Implementation Method 1
a hollow charge insert (5), in particular a conical shaped charge insert (5), which is adapted to the tubular housing element (2)
Implementation Method 2
The penetrating power of the shaped charge is selected in such a way that it penetrates the shell of the ammunition to be defused

AI summary
In order to reduce significantly the effort involved in the logistics and making safe of destructive charges (100) containing hollow charges, intended particularly for bomb disposal by remotely controlled detonation, the invention proposes that the destructive charge (100) should not be kept, i.e. stored and transported, as a ready-assembled charge, but instead all components that are not relevant to safety, such as the preferably tubular casing element (2) of the destructive charge (100), a hollow charge insert (5) and the cap (6) or cover (22) intended for receiving the detonator, should be stored and transported separately as a construction kit (1, 1'). The destructive charge (100) is then only assembled on site, together with the explosive (12) that is required for the hollow charge and is available at the site and together with the electrical detonator, on condition that the person in charge of bomb disposal operations authorizes their use for blowing up the bombs.
