Reinforced Textile for Security Baggage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The manufacture of laminated reinforced textiles for soft security baggage is costly due to the complexity of bonding mesh layers, which can separate from the outer and liner, leading to security vulnerabilities.
Innovation Solution
A reinforced textile comprising a sheet of fabric with a continuous metal or high-strength reinforcing strand stitched in a mesh-like pattern, using a lockstitch to secure the strand to the fabric, allowing for a cost-effective and secure construction without looping or knotting the strand at intersections, and optionally using adhesive or welding for additional reinforcement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If laminated construction is used to enclose mesh between inner and outer bags, then security against slicing is improved, but manufacturing cost increases
Solution Approach 1:
The patent combines the mesh reinforcement and outer fabric into a single laminated panel structure, where the mesh is permanently bonded to the fabric surface. This integration eliminates the need for separate mesh bags and multiple bonding operations, reducing manufacturing complexity while maintaining security against slicing attacks.
Solution Approach 2:
The invention uses composite material construction by bonding mesh to fabric panels to create a unified reinforced structure. This composite approach provides both the cut-resistance of metal mesh and the durability of fabric, achieving high security without the complexity of multi-component assembly.
2Reliability
If mesh is used for reinforcement, then security against theft is improved, but mesh may separate from outer and liner due to collapse tendency
Solution Approach 1:
The mesh is pre-formed into panels with the desired shape and reinforcement pattern before being bonded to the fabric. This preliminary preparation ensures proper mesh configuration and eliminates the need for on-site assembly, preventing separation issues that would arise from improper installation or collapse during manufacturing.
Solution Approach 2:
By bonding the mesh permanently to the fabric panels during manufacturing, the invention creates a unified structure where the mesh and fabric act as a single composite material. This integration prevents the mesh from separating from the outer and liner, eliminating the stability problem while maintaining theft resistance.
3Ease of manufacture
If continuous reinforcing strand is stitched in mesh pattern, then manufacturing cost is reduced, but strand may be pulled through fabric
Solution Approach 1:
The patent introduces adhesive bonding as an intermediary method to supplement the stitching connection. The adhesive is applied to the fabric surface and bonds the mesh to the fabric, creating a dual-mechanism attachment system. This prevents the strand from being pulled through the fabric while maintaining cost-effectiveness compared to purely mechanical fastening methods.

AI summary
A reinforced textile suitable for the construction of security baggage comprises a continuous reinforcing strand arrayed in a pattern overlying a surface of a fabric, the reinforcing strand being fixed to the fabric as, for instance, with stitching, tape or welds extending lengthwise along the reinforcing strand.
