Solution Overview

Problem

Conventional metal fence systems are not resilient enough for adverse environments and can interfere with radar systems, leading to confusion in flight management during adverse weather conditions.

Innovation Solution

A non-metallic fence system made from poly-glass, PVC, polyurethane, and polypropylene materials, featuring a snap-lock securing device with an open face strut profile that allows for easy installation and removal, and a breakaway post design to prevent damage from large objects, while being invisible to radar.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional metal fence systems are used, then structural strength and durability are provided, but they interfere with radar systems and are not resilient enough for adverse environments

Engineering Contradiction:

Improveradar functionalityVSAvoidstructural strength

Core Design Contradiction:

ReliabilityVSStrength

Solution Approach 1:

The patent employs composite materials including fiber-reinforced polymers and aluminum alloys that provide structural strength equivalent to metal while being non-conductive to radar waves. The composite structure combines rigid components for strength with radar-transparent materials to eliminate radar interference.

Inventive Principle:

Principle #40Composite materials

2Reliability

If conventional metal fence systems are used, then boundary security is provided, but they cause confusion in flight management during adverse weather conditions

Engineering Contradiction:

Improveflight management clarityVSAvoidradar interference

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The invention extracts the harmful metallic components from the fence system and replaces them with non-metallic alternatives. This removal of metal elements eliminates radar interference while preserving the fence's boundary security function through alternative materials and design configurations.

Inventive Principle:

Principle #2Taking out (Extraction)

3Strength

If rigid metal fence structures are used, then boundary security is maintained, but damage from large objects causes system failure

Engineering Contradiction:

Improveboundary securityVSAvoidcollision damage

Core Design Contradiction:

StrengthVSObject-affected harmful factors

Solution Approach 1:

The patent incorporates dynamic, flexible components that can deform and absorb impact forces from large objects rather than rigidly resisting them. The flexible mesh and articulated connections allow the fence to bend and return to position, preventing catastrophic failure while maintaining boundary security.

Inventive Principle:

Principle #15Dynamics

4Reliability

If traditional securing devices are used, then fabric attachment is achieved, but installation and removal are time-consuming

Engineering Contradiction:

Improvefabric attachment securityVSAvoidinstallation time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The securing device is segmented into modular components including quick-connect elements and discrete attachment points. This segmentation allows individual sections to be independently installed or removed without affecting the entire fence system, significantly reducing installation and maintenance time while maintaining secure fabric attachment.

Inventive Principle:

Principle #1Segmentation
