Solution Overview

Problem

Existing barriers are inadequate for preventing terrorist truck ramming attacks using heavy goods vehicles, as they are either too heavy for temporary installations or ineffective against such vehicles, and existing lightweight solutions fail to stop heavy vehicles.

Innovation Solution

A lightweight anti-ramming truck device featuring horizontal arresting bars and pivot bars forming an angle of at least 100°, with anchoring spikes and connectors that facilitate pivoting and maximize kinetic energy absorption, allowing easy setup and dismantling by law enforcement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If heavy barriers such as concrete barriers or metal posts are used, then protection against truck ramming attacks is improved, but device weight and installation complexity increase, requiring permanent installation or heavy logistics with lifting devices

Engineering Contradiction:

Improveprotection against truck ramming attacksVSAvoidbarrier weight

Core Design Contradiction:

ReliabilityVSWeight of moving object

Solution Approach 1:

The barrier is divided into multiple lightweight modular sections that can be assembled together. Each section consists of vertical posts connected by horizontal beams, creating a segmented structure that provides adequate protection while remaining lightweight and deployable without heavy logistics equipment

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The barrier incorporates movable and adjustable components, including telescopic posts and detachable connections, allowing the structure to adapt to different deployment scenarios. The dynamic nature enables easy setup and takedown by small teams without requiring permanent installation or heavy lifting devices

Inventive Principle:

Principle #15Dynamics

2Ease of operation

If lightweight barriers are used, then ease of deployment is improved, but effectiveness against heavy vehicles deteriorates

Engineering Contradiction:

Improveease of deploymentVSAvoideffectiveness against heavy vehicles

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The barrier employs composite construction combining lightweight materials such as aluminum or composite polymers for the structural elements. These materials provide sufficient strength to withstand heavy vehicle impacts while maintaining low weight, enabling easy deployment by small teams without compromising effectiveness against terrorist vehicles

Inventive Principle:

Principle #40Composite materials

Solution Approach 2:

The barrier components are pre-assembled into modular sections with pre-configured connections, allowing rapid deployment by simply unrolling or assembling the pre-prepared sections. This preliminary preparation eliminates the need for complex on-site assembly while ensuring the barrier is fully functional against heavy vehicles upon deployment

Inventive Principle:

Principle #10Preliminary action

3Reliability

If permanent installation methods are used, then protection reliability is improved, but adaptability to temporary events deteriorates

Engineering Contradiction:

Improveprotection reliabilityVSAvoidadaptability to temporary events

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The barrier is designed as a temporary, movable structure that can be quickly deployed and removed from temporary event locations. The dynamic connections and modular design allow the same barrier system to be reused at different locations for concerts, festivals, and other temporary gatherings, providing reliable protection without permanent installation

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The barrier system is segmented into portable sections that can be easily transported and reconfigured for different event locations. This segmentation enables the barrier to adapt to various temporary event requirements while maintaining protection reliability, as the modular sections can be assembled to match the specific deployment scenario

Inventive Principle:

Principle #1Segmentation
