Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional bag-like satchel charges are used, then the charge can be filled with explosives, but the charge is bulky and difficult to prime
Solution Approach 1:
The demolition charge is divided into separate functional components: a rigid hollow case for explosives, detachable magnets for attachment, and separate initiation systems. This segmentation allows the charge to be more compact and easier to handle while maintaining all necessary functions.
Solution Approach 2:
The rigid hollow case is designed to serve multiple functions: containing explosives, providing structural support, enabling magnetic attachment, and accommodating multiple initiation methods. This multi-functionality reduces the need for separate components, making the overall system more compact and easier to operate.
2Reliability
If traditional satchel charges contain detonating cord and sensitive boosters, then initiation is possible, but the charge is susceptible to accidental initiation
Solution Approach 1:
The initiation systems (blasting caps, detonators, detonating cords) are designed to be installed just prior to demolition rather than being pre-assembled. This preliminary action timing separates the sensitive initiation components from the explosive charge during storage and transport, reducing accidental initiation risk while ensuring reliable initiation when needed.
Solution Approach 2:
The sensitive initiation components are extracted from the main charge body and stored separately in the rigid hollow case. This separation allows the charge to be handled and positioned without the initiation systems attached, reducing the risk of accidental initiation while maintaining the ability to reliably initiate the charge when required.
3Adaptability or versatility
If traditional satchel charges are used, then the charge can be placed on or near a target, but the charge cannot be mounted by magnets or on support apparatuses
Solution Approach 1:
The rigid hollow case is designed with integrated magnets and threaded receptacles that enable multiple mounting methods: magnetic attachment to ferrous surfaces, threaded attachment to support structures, and direct placement on targets. This universal mounting capability allows the same basic design to be adapted to various deployment scenarios without increasing overall system complexity.

Function Achieved in This Case
The solution provides a reliable, versatile, and safe demolition charge system that can be easily deployed and tailored for specific tasks, reducing the risk of accidental initiation and enhancing operational effectiveness by allowing multiple initiation methods and magnetic attachment to targets.
Implementation Method 1
At least one magnet is provided in the container and is engageable with a ferrous metal target

AI summary
A demolition charge system has a multi-primed initiation system with a rigid container having interconnected thin end walls, side walls, a base and a lid. The lid continuously fits onto the end and side walls to cover and contain an internal chamber. Each of the ends walls has a threaded opening longitudinally aligned with each other. An elongated thin-walled tube longitudinally extends through the internal chamber and has threaded ends engaging inner portions of the threaded openings to securely hold the tube in the container. At least one demolition initiator is capable of longitudinally extending in the tube and a main charge in the internal chamber is positionable in abutting contact along the tube to assure demolition. Magnets assure magnetic securing of the demolition system on a ferrous target.
