Solution Overview

Problem

Existing anti-theft solutions for carrying bags, such as handbags and luggage, are often bulky, inflexible, and difficult to assemble, with crimped wire meshes being prone to breakage and causing wear, while also failing to provide adequate security against cutting and snatching.

Innovation Solution

A flexible security panel assembly featuring a wire matrix with closed wire shapes, integrated into the bag's structure between the exterior and interior layers, which includes a cut-resistant cable in the strap and locking mechanisms for zippers, preventing access and snatching.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If crimped wire mesh is used for security, then cutting resistance is improved, but the structure becomes bulky and rigid

Engineering Contradiction:

Improvecutting resistanceVSAvoidbulkiness

Core Design Contradiction:

StrengthVSVolume of moving object

Solution Approach 1:

The patent replaces rigid crimped wire mesh with a flexible panel assembly comprising thin flexible material layers (first and second layers) that can conform to the bag's contours. These layers enclose a wire matrix providing security while maintaining flexibility and reducing bulk, directly resolving the contradiction between cutting resistance and bulkiness.

Inventive Principle:

Principle #30Flexible shells and thin films

Solution Approach 2:

The invention creates a composite structure combining flexible material layers with a wire matrix embedded between them. This composite approach integrates the cutting resistance of wire with the flexibility and thin profile of material layers, achieving both security and reduced bulk simultaneously.

Inventive Principle:

Principle #40Composite materials

2Strength

If crimped wire mesh is used for security, then cutting resistance is improved, but flexibility is reduced

Engineering Contradiction:

Improvecutting resistanceVSAvoidflexibility

Core Design Contradiction:

StrengthVSAdaptability or versatility

Solution Approach 1:

The patent employs flexible material layers as the primary structure, allowing the security panel to bend and adapt to the bag's shape. The wire matrix is embedded within these flexible layers rather than forming a rigid external mesh, preserving flexibility while maintaining cutting resistance.

Inventive Principle:

Principle #30Flexible shells and thin films

Solution Approach 2:

The wire matrix is nested within the flexible material layers, with the first and second flexible layers enclosing the wire structure. This nesting allows the flexible layers to move independently while the wire provides underlying security, resolving the contradiction between rigidity for security and flexibility for adaptability.

Inventive Principle:

Principle #7Nested doll (Nesting)

3Strength

If crimped wire mesh is used for security, then cutting resistance is improved, but assembly difficulty increases

Engineering Contradiction:

Improvecutting resistanceVSAvoidassembly difficulty

Core Design Contradiction:

StrengthVSEase of manufacture

Solution Approach 1:

The security panel is segmented into distinct components: first flexible material layer, second flexible material layer, and wire matrix. These segments can be manufactured separately and then assembled by positioning the wire matrix between the layers and securing them together, simplifying the assembly process compared to forming integrated crimped mesh.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The wire matrix and flexible layers can be prepared in advance as separate components. The wire matrix is positioned between the layers during assembly rather than being attached to pre-formed rigid mesh, allowing for easier integration into the bag structure and reducing assembly complexity.

Inventive Principle:

Principle #10Preliminary action

4Strength

If crimped wire mesh is used for security, then cutting resistance is improved, but aesthetic appearance deteriorates

Engineering Contradiction:

Improvecutting resistanceVSAvoidaesthetic appearance

Core Design Contradiction:

StrengthVSShape

Solution Approach 1:

The flexible material layers serve as the visible exterior surface of the security panel, replacing the unsightly crimped wire mesh with smooth, aesthetically pleasing material. The wire matrix remains hidden between the layers, providing security without compromising appearance.

Inventive Principle:

Principle #30Flexible shells and thin films

Solution Approach 2:

The wire matrix is localized between the flexible layers where it provides security, while the flexible material layers form the visible surface with desirable aesthetic qualities. This local differentiation allows the security function and aesthetic function to occupy different spatial zones, resolving the contradiction between strength and appearance.

Inventive Principle:

Principle #3Local quality

AI summary

In various embodiments, a carry (or carrying) bag is provided that includes an interior, substantially cut-resistant security panel assembly with a matrix of wires secured between or on one or more flexible material layers. Also in various embodiments, the security panel assembly may be positioned intermediate the bag outside wall and a lining of the bag, and in other embodiments, may also take the form of an expansion panel. Second or secondary locking fasteners are also provided to lock first or primary fasteners to or within the carrying bag, to provide security for compartments and pockets. A strap with one or more security cables, and various locking fasteners, may be attached to the carry bag. Methods for forming such security panel assemblies, expansion panels, and carrying straps are also disclosed.
