Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for disposing of large-scale ordnance explosives are inefficient, costly, and pose safety risks due to the need for mechanical sawing and high-temperature furnaces, which are time-consuming and do not comply with environmental regulations, especially when dealing with large-format drop ammunition.
Innovation Solution
A method involving inductive heating using an induction coil and a robotic arm to thermally soften explosives within the casing, allowing for controlled release into a receiving space without mechanical stress, using a compact device that adapts to various ordnance designs and minimizes environmental impact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mechanical sawing and high-temperature furnaces are used for disposal, then complete destruction of explosives is achieved, but processing time increases to 2-3 days for cutting and 1 week for combustion
Solution Approach 1:
The patent replaces mechanical sawing with inductive heating that thermally softens the explosive material, allowing it to be extruded through a die under pressure. This substitution of mechanical cutting with thermal processing reduces processing time from 2-3 days to a fraction of that time while achieving complete destruction of the explosives through controlled thermal degradation.
Solution Approach 2:
The patent changes the physical state of the explosive material by heating it to its melting point and then to decomposition temperature. By controlling temperature parameters and applying pressure, the explosive is transformed from a solid state suitable for handling to a softened state for extrusion, and finally to decomposed state for complete destruction, significantly reducing processing time.
2Reliability
If high-temperature furnaces are used for combustion, then explosives are completely destroyed, but energy consumption increases and environmental regulations must be strictly complied with
Solution Approach 1:
The patent replaces high-temperature furnace combustion with inductive heating that directly heats the explosive material to its decomposition temperature. This localized inductive heating is more energy-efficient than furnace combustion because it heats only the explosive material and not a large volume of air, reducing energy consumption while achieving complete destruction.
Solution Approach 2:
The patent extracts the explosive material from its container and processes it separately through inductive heating and extrusion. By separating the explosive from the container and processing it in a controlled manner, the system achieves complete destruction with lower energy consumption and easier compliance with environmental regulations compared to furnace combustion of entire ordnance.
3Reliability
If large-format drop ammunition is processed using traditional methods, then disposal is achieved, but handling risks increase due to size and mass of explosive
Solution Approach 1:
The patent segments the large-format drop ammunition by separating the explosive material from its container. The explosive is extruded through a die in a controlled manner, breaking it into manageable portions that can be safely processed. This segmentation reduces handling risks by converting a single large hazardous object into smaller, more controllable portions.
Solution Approach 2:
The patent replaces mechanical handling and cutting of large-format ordnance with inductive heating that softens and extrudes the explosive material. This thermal processing method reduces handling risks by eliminating the need for mechanical cutting operations that could generate sparks or cause accidental ignition, while also reducing the mass that needs to be manually handled.
4Ease of manufacture
If mechanical cutting is used to section ordnance, then disposal preparation is achieved, but device complexity and cost increase
Solution Approach 1:
The patent replaces complex mechanical cutting equipment with a relatively simple inductive heating system consisting of an induction coil, heating element, and extrusion die. This substitution reduces device complexity and cost while achieving the same disposal preparation function, as the thermal processing system is simpler than precision mechanical cutting equipment required for large-format ordnance.

AI summary
The present invention relates to a method for deploying an explosive substance (3) from a jacket (2) of a large-size weapon (1), in particular a dropping munition, comprising splitting the jacket (2) in a region of a maximum diameter (DM). In order to develop a known device so as to thus also design a corresponding method to be more efficient, while exploiting additional cost and efficiency potential and providing increased safety and simplified handling, according to the invention, the jacket (2) is cut open at a transition into a cylindrical portion (4) acting as a separating plane (S) and the resulting opening in the portion (4, 5) is held over a recess (10) which opens up a receiving chamber (11), wherein an induction coil (9) passes over the jacket (2) of the portion (4, 5) in order to sufficiently thermally soften the explosive substance (3) for deployment from the jacket (2) and to bring said substance into the receiving chamber (11) in a defined manner.
