Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for hand-emplacing stand-off demolition charges do not effectively account for the required air gap and additional strength needed to support a cantilevered load, making them cumbersome and inefficient for optimal performance.
Innovation Solution
A lightweight, collapsible attachment bracket with rare earth magnets for ferrous surfaces and a high-strength textile skirt with hooks and rings for other surfaces, allowing adjustable stand-off distances up to ten inches, securely holding charges of seven or more pounds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If direct contact placement is used, then attachment simplicity is improved, but stand-off distance capability deteriorates
Solution Approach 1:
The bracket serves as an intermediary device between the charge and the target surface. It includes a mounting interface that attaches to the target and a support structure that extends outward to hold the charge at a stand-off distance, thereby enabling both secure attachment and required air gap without requiring complex impromptu solutions
Solution Approach 2:
The bracket is designed as a segmented structure with distinct functional components: a mounting interface for attachment to the target surface, an adjustable stand-off mechanism to create the air gap, and a charge holder to secure the demolition charge. This segmentation allows each component to be optimized for its specific function while working together as an integrated system
2Reliability
If stand-off distance is increased, then optimal charge performance is improved, but attachment strength requirement worsens
Solution Approach 1:
The bracket incorporates an adjustable stand-off mechanism that allows the distance between the charge and target surface to be dynamically changed. This enables optimization of the air gap for charge performance while the adjustable nature allows the structure to be configured for different performance requirements and attachment scenarios
Solution Approach 2:
The bracket utilizes composite construction combining materials with high strength-to-weight ratios to create a structure that can support the cantilevered load at extended distances. The composite design allows the bracket to maintain sufficient strength for supporting charges at stand-off distances while keeping the overall weight manageable for field deployment
3Adaptability or versatility
If adjustable stand-off is implemented, then application versatility is improved, but device complexity worsens
Solution Approach 1:
The adjustable stand-off mechanism allows the bracket to be configured for different application requirements by changing the distance between the charge and target surface. This dynamic adjustability provides versatility for different charge types and performance requirements without requiring multiple different bracket designs
Solution Approach 2:
The bracket incorporates a collapsible design that can be compacted into a smaller configuration for transport and deployment, then extended to the required stand-off distance for use. This collapsible feature reduces the complexity of carrying and deploying the bracket while maintaining the ability to achieve various stand-off distances when needed

AI summary
Exemplary apparatus, systems, and methods to provide an ability to quickly and securely hand emplace stand-off demolition charges to various surfaces or structures including surfaces including any flat surface. An aspect of the embodiment of the invention is a lightweight attachment bracket that will hold charges at distances up to (e.g., ten inches) away from a vertical target. The bracket is collapsible, therefore provides a user adjustable stand-off, which is necessary for some applications. Attachment to ferrous material can be instant through a set of rare earth metals imbedded in the base of the bracket. A skirt of high strength textile material provides attachment to other surfaces via integrated hooks and rings. Alternative embodiments of the invention could include an electromagnetic system provided to couple the bracket with a battery in order to provide a limited amount of power to operate the system.
