Segmented Anti-Ballistic Insert Assembly for Backpacks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing backpacks and luggage lack effective anti-ballistic protection against projectiles, failing to provide sufficient resistance to penetration by bullets or other projectiles.
Innovation Solution
A bullet-resistive or projectile-resistive insert assembly comprising anti-ballistic material sheets sandwiched between anterior and posterior envelope layers, with optional pocket formations and a zipper mechanism for access, and a handle for easy carrying, designed for removable insertion into packs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If anti-ballistic material sheets are inserted into the backpack, then projectile resistance is improved, but device complexity increases
Solution Approach 1:
The anti-ballistic protection system is segmented into separate components: material sheets, envelope assembly, and insert assembly. This allows the backpack to maintain its simple structure while adding protection through a removable insert that can be independently manufactured and assembled.
Solution Approach 2:
The material sheets are nested within the envelope assembly, which is then inserted into the backpack. This nested structure allows the protective function to be integrated without permanently altering the backpack's complexity, as the envelope and sheets can be removed as a unit.
2Ease of operation
If the insert assembly is made removable, then ease of operation is improved, but reliability of protection decreases
Solution Approach 1:
The envelope assembly is pre-configured with attachment means that engage with corresponding features in the backpack before use. This preliminary arrangement ensures that when the insert assembly is installed, it provides reliable protection without requiring complex attachment procedures during actual use.
Solution Approach 2:
The envelope assembly serves as an intermediary between the material sheets and the backpack. It provides a standardized interface with attachment means that ensure reliable connection while allowing easy removal and reinstallation, thus maintaining both ease of operation and protection reliability.
3Reliability
If multiple material sheets are stacked, then projectile resistance is improved, but weight increases
Solution Approach 1:
The patent employs composite material structures where multiple material sheets of different compositions are stacked to achieve optimal penetration resistance. Each sheet can be made from materials with specific properties (e.g., aramid fibers, polyethylene), allowing the system to achieve high protection with minimal weight by selecting appropriate material combinations.

AI summary
A bullet-resistive or projectile-resistive insert assembly includes at least one anti-ballistic material sheet formed peripherally for receipt in a sheet-covering envelope. An exterior sheet-covering envelope assembly envelops or covers the anti-ballistic material sheet or sheets and includes anterior and posterior envelope material layers. The anterior and posterior envelope material layers are respectively received in anterior and posterior relation relative to the anti-ballistic material thereby sandwiching the same intermediate the enveloping material layers. The anti-ballistic material comprises an outer peripheral stack contour formed to match and mate with an inner peripheral envelope contour of the exterior sheet-covering envelope assembly. The anti-ballistic material includes an anterior stack section, a central stack section, and a posterior stack section. The central stack section has a central stack top-to-bottom length relatively greater in magnitude than an anterior stack top-to-bottom length and a posterior stack top-to-bottom length respectively associated with the anterior and posterior stack sections.
