Solution Overview

Problem

Existing security barriers for ships are bulky, inefficient to store, and costly due to their specific shape and materials, making them difficult to deploy and maintain.

Innovation Solution

A modular security device with a barrier and panel that can transition between unassembled and assembled configurations, using flexible materials and living hinges to form a bulbous overhang, allowing efficient storage and easy deployment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional security barriers are used to provide protection against unauthorized access, then security protection is improved, but storage efficiency deteriorates due to bulky size

Engineering Contradiction:
Improvesecurity protectionVSAvoidstorage space
Core Design Contradiction:
ReliabilityVSVolume of moving object

Solution Approach 1:

The security barrier is divided into multiple panels that can be separated and stored individually. Each panel can be detached from the railing and stacked in a compact arrangement, significantly reducing storage volume while maintaining security protection capability when deployed

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The barrier panels are designed to be dynamically configurable between a deployed security barrier configuration and a collapsed storage configuration. The panels can be quickly assembled around railings when needed and disassembled for compact storage when not in use, providing adaptive volume management

Inventive Principle:
Principle #15Dynamics

2Reliability

If traditional security barriers with specific bulbous shapes are manufactured, then security protection is improved, but manufacturing cost deteriorates

Engineering Contradiction:
Improvesecurity protectionVSAvoidmanufacturing cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The barrier panels use standard rectangular sheet dimensions with uniform thickness, changing the geometric parameters from complex bulbous shapes to simple planar forms. This allows the panels to be manufactured using standard sheet metal forming processes, significantly reducing tooling costs and manufacturing complexity while maintaining security function through the assembled configuration

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

By segmenting the barrier into multiple flat panels rather than manufacturing a single complex bulbous structure, the invention enables independent manufacturing of each panel using standard processes, reducing overall manufacturing cost and improving ease of production

Inventive Principle:
Principle #1Segmentation

3Reliability

If traditional security barriers are deployed, then security protection is improved, but deployment speed deteriorates due to complex assembly

Engineering Contradiction:
Improvesecurity protectionVSAvoiddeployment time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The barrier panels are pre-configured with attachment features and designed to fit together in a predetermined sequence. The panels can be pre-assembled into sections or pre-attached to railings, reducing the time required for final deployment. The modular design allows for quick connection and disconnection without complex assembly procedures

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The barrier system is designed for dynamic deployment, allowing panels to be quickly assembled and disassembled. The panels can be rapidly attached to railings and configured into the security barrier position, enabling fast response to security needs without time-consuming assembly processes

Inventive Principle:
Principle #15Dynamics

AI summary

A security device is disclosed comprising: a barrier; and a panel, wherein the security device may be transitioned repeatedly between a first configuration and a second configuration, in the first configuration the security device is unassembled and at least the barrier may be arranged in a storage configuration in which the barrier curves or bends through a first angle, and in the second configuration the security device is assembled in an arrangement for use, in which the security device may be assembled around a rail; and wherein, in the second configuration, at least a part of the panel is orientated to be substantially vertical, and the barrier is curved, bent or folded through a second angle, which is greater than the first angle, to protrude away from the panel in a horizontal direction, perpendicular from a plane extending vertically through the rail, to provide an overhang on an exterior side of the rail.
