Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing bullet-proof backpacks do not adequately protect the head, neck, left and right shoulders, and pelvic region of a user, and neither do bullet-proof vests provide comprehensive body protection.

Innovation Solution

A bullet-proof backpack design that includes movable sections with integrated bullet-proof materials to cover the back of the neck, head, left and right shoulders, and pelvic region, allowing for deployment to act as a full-body shield when needed.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If a traditional bullet-proof vest is worn, then the torso is protected, but the head, neck, shoulders, and pelvic region remain exposed

Engineering Contradiction:

Improvebody protection coverageVSAvoidprotection area

Core Design Contradiction:

Object-affected harmful factorsVSAdaptability or versatility

Solution Approach 1:

The protective system is divided into multiple independent sections: a base backpack with bullet-proof material covering the torso, and separate movable protective panels for the head, neck, shoulders, and pelvic region. Each section can be independently deployed or stored, allowing selective protection of different body areas based on the threat level and user needs.

Inventive Principle:

Principle #1Segmentation

2Ease of operation

If a bullet-proof backpack is used to carry belongings, then convenience is improved, but protection of the head, neck, shoulders, and pelvic region is insufficient

Engineering Contradiction:

ImproveconvenienceVSAvoidprotection coverage

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The backpack serves multiple functions: it acts as a standard carrying bag for daily use with storage compartments for belongings, while simultaneously serving as a protective shield when the movable panels are deployed. The same structure provides both utility (carrying items) and protection (bullet-resistant coverage), eliminating the need for separate protective equipment.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Object-affected harmful factors

If movable sections are added to expand protection area, then body coverage is improved, but device complexity increases

Engineering Contradiction:

Improveprotection areaVSAvoidstructure

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The protective panels are designed to be movable rather than fixed, allowing them to be deployed only when protection is needed. The panels can be manually or automatically extended from the backpack body, providing expanded coverage during threats while maintaining a compact, simple form factor during normal use. This dynamic configuration reduces the perceived complexity by only adding functionality when required.

Inventive Principle:

Principle #15Dynamics

AI summary

A bullet-proof backpack includes a back protection section having bullet-proof material integrated therein. The back protection section is sized to cover a portion of a user's upper back when the backpack is worn by the user. The bullet-proof backpack also includes a neck protection section having bullet-proof material integrated therein. The neck protection section is movably connected to the backpack and operable to move from a stored position to a deployed position. When the neck protection section is in its stored position, it is stored against a portion of the backpack. When the neck protection section is in its deployed position, it covers a back of the user's neck and a back portion of the user's head when the backpack is worn by the user.
