Bulletproof Backpack Hood Weight Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for improved bulletproof devices that children and adults can easily carry for protection against gun violence, as existing options are not commonly used or are not designed for everyday wearability.
Innovation Solution
A bulletproof backpack with integrated bulletproof materials in the body, hood, and shoulder straps, featuring panels made of materials like Kevlar and Spectra, and a connecting mechanism to distribute weight evenly, allowing users to carry protective gear without separate equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If bulletproof materials are integrated into the backpack, then protection capability is improved, but weight increases
Solution Approach 1:
The patent applies local quality by integrating bulletproof panels specifically in high-risk areas (back, head, and shoulder straps) rather than making the entire backpack uniformly bulletproof. This localized approach provides necessary protection while minimizing overall weight increase.
Solution Approach 2:
The patent uses composite materials combining bulletproof materials (such as Kevlar or Spectra) with standard backpack materials. This allows the backpack to maintain its everyday functionality while incorporating protection only where absolutely necessary, optimizing the weight-protection ratio.
2Reliability
If a hood with bulletproof panel is added, then head protection is improved, but device complexity increases
Solution Approach 1:
The patent merges the hood and bulletproof panel into a single integrated component. The bulletproof panel is incorporated directly into the hood structure, eliminating the need for separate head protection devices and simplifying the overall system while maintaining head protection capability.
3Ease of operation
If strap connectors are added to balance hood weight, then comfort is improved, but device complexity increases
Solution Approach 1:
The patent applies equipotentiality by using strap connectors to distribute the weight of the hood evenly across the shoulders. This balances the weight distribution and prevents the hood from falling back, improving comfort without requiring complex mechanical systems.
4Reliability
If bulletproof panels are integrated into shoulder straps, then torso protection is improved, but weight increases
Solution Approach 1:
The patent applies local quality by placing bulletproof panels specifically in the shoulder strap areas that contact the torso, providing protection only where needed during wear. This localized protection minimizes weight addition while maximizing torso protection effectiveness.

AI summary
A bulletproof backpack is disclosed. The bulletproof backpack includes a body having a front section, a rear section, a base, and a cover section. The front section, the rear section, the base, and the cover section form an interior of the body. The bulletproof backpack includes a first panel connecting the rear section. The bulletproof backpack includes a hood extending from the cover section. The bulletproof backpack includes a second panel connecting the hood. The bulletproof backpack includes shoulder straps connecting the rear section allowing a user to carry the bulletproof backpack. The bulletproof backpack includes strap connectors extending from the hood. Each of the first panel and the second panel is capable of blocking bullets and explosion fragments for protecting the user's back and head, respectively. The strap connectors connect the shoulder straps to balance the weight of the hood and prevent the hood from falling back.
