Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing physical barriers, such as fences made of high-density steel mesh, often require upgraded security ratings due to various factors, and there is a need for cost-effective methods to enhance their security without replacing them entirely or constructing new fences with high security ratings from scratch.

Innovation Solution

The solution involves adding a deterrent structure, which can include additional mesh panels, flat bars, or tubular frameworks to existing mesh panels and supports, with features like inclined surfaces to prevent footholds and handholds, and filling tubular members with attack-resistant materials to enhance resistance against cutting tools and climbing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a higher security rating fence is erected from scratch, then security rating is improved, but cost and time consumption increase

Engineering Contradiction:

Improvesecurity ratingVSAvoidcost and time

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The fence system is divided into modular components: existing mesh panels, newly added deterrent structures, and reusable supports. This segmentation allows selective upgrading of security features without replacing the entire fence system, reducing cost and time while improving security rating.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Deterrent structures are nested onto existing mesh panels and supports. The deterrent structures incorporate mesh panels within tubular frameworks, creating layered protection that enhances security without requiring complete reconstruction of the fence.

Inventive Principle:

Principle #7Nested doll (Nesting)

2Strength

If deterrent structures are added to existing mesh panels, then attack resistance is improved, but structural complexity increases

Engineering Contradiction:

Improveattack resistanceVSAvoidstructural complexity

Core Design Contradiction:

StrengthVSDevice complexity

Solution Approach 1:

Deterrent structures are applied locally to specific mesh panels or sections where enhanced security is needed, rather than uniformly across the entire fence. This allows targeted reinforcement of high-risk areas while maintaining simplicity in lower-risk zones.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The deterrent structures combine multiple materials and structures: tubular frameworks (steel), mesh panels (welded wire), and infill materials (concrete, ceramic, or steel shot). This composite approach creates multi-layered protection that resists various attack methods while maintaining structural integrity.

Inventive Principle:

Principle #40Composite materials

3Strength

If tubular members are filled with attack-resistant materials, then resistance to cutting tools is improved, but weight increases

Engineering Contradiction:

Improveresistance to cutting toolsVSAvoidweight of tubular members

Core Design Contradiction:

StrengthVSWeight of moving object

Solution Approach 1:

The deterrent structures offer variable fill options with different weight-strength characteristics. Users can select from concrete, ceramic materials, or steel shot based on the specific security requirements and weight constraints of each application, optimizing the parameter of density for different scenarios.
