Solution Overview

Problem

Existing barriers for protecting against vehicle attacks are costly and time-consuming to deploy due to their embedding or attachment to the ground, inhibiting rapid deployment.

Innovation Solution

A portable barrier design featuring support members with obliquely extending feet and spikes that pivot upon impact, engaging the ground and vehicle undercarriage to arrest movement, allowing for rapid deployment by a single person.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If barriers are embedded into the ground or attached to the roadway surface, then the barriers can effectively stop vehicles, but the deployment becomes costly and time-consuming

Engineering Contradiction:

Improvevehicle stopping capabilityVSAvoiddeployment time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The barrier transitions from a static ground-embedded structure to a dynamic portable structure that can be rapidly deployed and repositioned. The support members with feet and spikes provide dynamic engagement with the ground surface without requiring excavation or permanent attachment.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The barrier design extracts the essential ground-engagement function from complex ground embedding procedures. By using removable feet and spikes that contact the ground surface directly, the system eliminates the need for costly and time-consuming excavation or attachment operations while maintaining vehicle stopping capability.

Inventive Principle:

Principle #2Taking out (Extraction)

2Reliability

If barriers are embedded into the ground or attached to the roadway surface, then the barriers can effectively stop vehicles, but the deployment becomes costly

Engineering Contradiction:

Improvevehicle stopping capabilityVSAvoiddeployment cost

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The design extracts the ground-engagement function from expensive ground embedding procedures. The feet and spikes provide sufficient ground contact and stability without requiring costly excavation, concrete work, or permanent roadway attachment, significantly reducing deployment costs.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The portable barrier uses simple, lightweight materials for the support members and interconnecting structure that can be rapidly manufactured and deployed without expensive ground works. The system prioritizes rapid deployment and repositioning over permanent installation.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

3Reliability

If the barrier is designed to pivot upon impact with spikes engaging the ground, then the barrier can arrest vehicle movement, but the structural complexity increases

Engineering Contradiction:

Improvevehicle arrest capabilityVSAvoidsupport member structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The support members feature asymmetric foot and spike configurations optimized for pivoting motion upon impact. The feet extend obliquely at specific angles to facilitate rotation about the second foot, while the spikes are positioned to engage the ground in an oblique direction toward the ground along the impact direction, creating effective vehicle arrest without complex mechanisms.

Inventive Principle:

Principle #4Asymmetry

Solution Approach 2:

The barrier structure uses its own geometry and the impact force itself to achieve the pivoting motion and ground engagement. The oblique extension of feet and spikes automatically guides the pivoting action upon vehicle impact, eliminating the need for external actuators, sensors, or control systems.

Inventive Principle:

Principle #25Self-service

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The portable barrier effectively stops vehicles by pivoting and digging into the ground and undercarriage, providing rapid and efficient protection without the need for ground excavation or attachment, facilitated by a transporter for easy deployment.

Implementation Method 1

upon impact of the portable barrier by a vehicle from a side facing the first ends of the support members, the portable barrier will pivot about the second foot of each support member
