Solution Overview

Problem

Existing pack products lack a bullet-proof function, which poses a risk to users in emergency situations, and conventional bullet-proof packs do not provide simultaneous protection for the back and chest.

Innovation Solution

A pack type body armor design featuring first and second pack bodies with detachable connections, incorporating cut-resistant, bulletproof, and antibacterial material layers, along with buoyancy elements, allowing for both pack and bullet-proof functions, as well as reduced bacterial breeding and potential use as a life jacket.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a conventional bullet-proof pack includes a pack body with a wear-resistant layer, interlayer, and bulletproof layer made of soft materials, then the pack has bullet-proof function, but the back and chest cannot be protected at the same time

Engineering Contradiction:

Improvebullet-proof functionVSAvoidsimultaneous protection for back and chest

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The body armor pack is divided into a first pack body and a second pack body, where the first pack body protects the back and the second pack body protects the chest. This segmentation allows simultaneous protection of both areas while maintaining bullet-proof functionality.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent transitions from a single-dimensional protection approach (one pack body) to a two-dimensional protection approach (first pack body for back, second pack body for chest), enabling comprehensive coverage of multiple body areas simultaneously.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Device complexity

If existing pack products do not have a bullet-proof function, then the pack structure remains simple, but users cannot be protected effectively in emergency situations

Engineering Contradiction:

Improvepack structureVSAvoiduser protection

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The patent merges the functions of a regular pack with bullet-proof protective gear by integrating bulletproof layers, cut-resistant material layers, and antibacterial material layers into the pack structure, allowing the pack to serve both carrying and protective functions.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The pack body is designed to perform multiple functions: it can be used as a regular pack for carrying items, as bullet-proof armor for back and chest protection, and as a life jacket when equipped with buoyancy elements, making it a universal protective device.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Reliability

If the bullet-proof layer is fixed in the pack body, then the pack has bullet-proof function, but the pack cannot be used as a life jacket

Engineering Contradiction:

Improvebullet-proof functionVSAvoidlife jacket function

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The connecting elements are designed to be detachable rather than fixed, allowing the pack configuration to change dynamically. The first and second pack bodies can be connected or separated based on whether bullet-proof protection or life jacket functionality is needed.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

Inventive Principle:

Principle #6Universality (Multi-functionality)

4Ease of operation

If the pack body is used for carrying things, then the pack is convenient to take out, but bacterial breeding occurs due to sweating of the user's body

Engineering Contradiction:

Improveconvenience of useVSAvoidbacterial breeding

Core Design Contradiction:

Ease of operationVSObject-generated harmful factors

Solution Approach 1:

The antibacterial material layer is integrated into the pack structure to automatically inhibit bacterial growth caused by user sweating, eliminating the need for separate antibacterial treatments or maintenance.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The pack incorporates composite material layers including cut-resistant material layers, bulletproof layers, and antibacterial material layers, combining multiple functional properties in a single integrated structure.

Inventive Principle:

Principle #40Composite materials
