Solution Overview

Problem

Backpacks are frequently targeted by thieves due to their accessibility and the valuable items they often carry, leading to concerns about personal belongings and the bag itself being stolen.

Innovation Solution

An anti-theft backpack design featuring a camouflaged backpack cover with a pull-out hood, made from waterproof and cut-resistant materials, which can be worn over the head to conceal the backpack, combined with secure fasteners and optional RFID shielding.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a backpack is made visible and accessible for easy access to contents, then ease of operation is improved, but vulnerability to theft and pickpocketing increases

Engineering Contradiction:

Improveaccessibility to contentsVSAvoidtheft and pickpocketing risk

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent employs a pull-out hood with camouflage pattern that can be extended to cover the backpack, changing its visual appearance from a conspicuous target to a concealed object that blends with the surroundings. This allows the backpack to maintain normal accessibility while reducing its visibility as a theft target.

Inventive Principle:

Principle #32Color changes

Solution Approach 2:

The camouflage hood is designed to be dynamically deployable - it can be pulled out when needed for concealment and retracted when not needed, allowing the backpack to adapt its level of camouflage based on the user's environment and needs. This dynamic feature resolves the contradiction by providing concealment only when necessary.

Inventive Principle:

Principle #15Dynamics

2Object-affected harmful factors

If a backpack cover is added to provide protection and camouflage, then protection against theft and weather is improved, but device complexity increases

Engineering Contradiction:

Improveprotection from theft, slashing, and weatherVSAvoidstructure with cover and hood

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The backpack cover is designed to serve multiple functions simultaneously: it provides camouflage concealment, protects against weather elements (rain and sun), and offers physical protection against slashing attacks. By combining these functions into a single integrated cover system, the patent reduces overall complexity compared to having separate components for each function.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The camouflage hood is nested within the backpack cover structure, allowing it to be stored compactly when not in use. The hood can be pulled out from the cover when camouflage is needed, creating a space-efficient design that minimizes the added bulk and complexity of the protective system.

Inventive Principle:

Principle #7Nested doll (Nesting)

3Strength

If cut-resistant material is used to protect against slashing, then strength and protection are improved, but weight of the backpack increases

Engineering Contradiction:

Improvecut-resistance against slashingVSAvoidbackpack weight

Core Design Contradiction:

StrengthVSWeight of moving object

Solution Approach 1:

The cut-resistant material is applied specifically to the backpack cover and hood areas that are most vulnerable to slashing attacks, rather than making the entire backpack from heavy protective material. This localized application provides necessary protection while minimizing the overall weight increase.

Inventive Principle:

Principle #3Local quality

AI summary

An anti-theft backpack that includes a bag, a backpack cover, and a pull-out hood. The backpack cover can cover the front side of the bag. The backpack cover includes a pocket encasing the pull-out hood. The pull-out hood may be taken out of the pocket and covered over the head of the wearer and the backpack cover. The pull-out hood camouflages with the backpack cover, thus virtually concealing it.
