Ordnance Ballistics Deployment System with Shear-Resilient Sleeve
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing attempts to integrate sensors and electronics into bullets have been unsuccessful due to high g-loads and harsh impacts, which often render delicate components inoperable, and there is a challenge in retaining these components within the target after impact.
Innovation Solution
An electronic ordnance delivery system where an electronics component is encased in a potting material within a housing exoskeleton, which is received by a deceleration sleeve with grooves that shear away upon impact to deploy the component, and an outer jacket with serrated sides that also shear away to facilitate deployment, ensuring the component is retained within the target.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If electronics components are integrated into bullets, then the bullet can provide tracking and communication capabilities, but the high g-loads and harsh impacts render the delicate components inoperable
Solution Approach 1:
The bullet is divided into distinct functional segments: a resilient deceleration sleeve with grooves that separate from the housing exoskeleton upon impact, allowing the electronics component to be deployed independently while the bullet continues penetrating the target
Solution Approach 2:
The resilient deceleration sleeve acts as a pre-designed cushioning mechanism that deforms upon impact to reduce the transmission of g-loads to the electronics component, protecting it from the harsh ballistic environment
2Reliability
If electronics components are embedded within the target, then the component can be retained, but the component may be damaged by the impact forces
Solution Approach 1:
The resilient deceleration sleeve serves as an intermediary between the bullet and the housing exoskeleton, absorbing impact forces through its deformation and preventing direct transmission of damaging forces to the electronics component while maintaining retention within the target
3Reliability
If a protective housing is used for electronics components, then the component is protected, but the housing increases the device complexity
Solution Approach 1:
The housing exoskeleton is designed as a thin-walled structure that provides adequate protection for the electronics component while minimizing structural complexity and weight, allowing the component to be deployed effectively within the target
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively deploys and maintains sensitive electronics components within a target by utilizing a deceleration sleeve and outer jacket that shear away upon impact, protecting the components and enabling successful deployment and operation.
Implementation Method 1
The deceleration sleeve has several grooves along the sides that extend rearwardly that, upon entry into a target, are caused to shear away to deploy the electronics component within a target
Implementation Method 2
The outer jacket has serrated sides that also shear away upon entry into a target body
Implementation Method 3
The core can be a lead core, and can have a rounded tip shape, a hollow-point tip shape, a flat-tip shape, or other shape

AI summary
An electronics ordnance delivery system that has an electronics component encased within a potting material, which itself is within a housing exoskeleton. A deceleration sleeve receives the exoskeleton, and is designed to shear away during a bullet's entry into a target body such that the electronics component is successfully deployed and remains in the target even if a part of the bullet exits the target. The system also includes an outer jacket that is also designed to shear away. The system can include a core that assists in the deployment of the electronics ordnance within the target.
