Solution Overview

Problem

Existing systems for arresting vehicle movement are primarily uni-directional and lack the ability to be rapidly reset and reused, which can lead to inefficiencies in stopping vehicles and potentially increase the risk of injury to occupants.

Innovation Solution

Bi-directional systems using retractable nets and brake-in-spool assemblies with sheave rollers, mechanical net deployment controllers, and laterally-slotted beams that can accommodate varying road widths and conditions, allowing for efficient deployment and reuse by utilizing available stopping space.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If uni-directional barrier systems are used to arrest vehicle movement, then the system can effectively stop vehicles in one direction, but the system cannot be rapidly reset and reused, leading to inefficiencies and increased injury risk

Engineering Contradiction:
Improvereset and reuse efficiencyVSAvoidbi-directional operation capability
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The patent applies multi-functionality by designing a single barrier system that can effectively arrest vehicles traveling in either direction along the roadway. The net barrier is configured to be deployable across the road surface, creating a universal solution that replaces the need for separate uni-directional barriers for each travel direction, thereby enabling rapid reset and reuse while maintaining adaptability to bidirectional traffic conditions.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Object-affected harmful factors

If traditional energy absorbing systems are used, then vehicle arrestment is achieved, but the available stopping space is not fully utilized, increasing the risk of injury to occupants

Engineering Contradiction:
Improveinjury risk to occupantsVSAvoidstopping space utilization
Core Design Contradiction:
Object-affected harmful factorsVSLength of stationary object

Solution Approach 1:

The patent applies dynamics by using a deployable net barrier system that can dynamically extend across the roadway to maximize the use of available stopping space. The net is stored in a retracted position and then deployed horizontally across the road surface when activation is required, allowing the system to utilize the full length of the barrier structure for energy absorption during vehicle arrestment, thereby reducing injury risk to occupants while optimizing stopping space utilization.

Inventive Principle:
Principle #15Dynamics

AI summary

Systems and methods for arresting vehicles or other moving objects are detailed. The systems may be bi-directional, so as to arrest vehicles on either side of a barrier. They additionally may be reset for reuse relatively rapidly following deployment and comprise mechanical controllers for facilitating suitable deformation of the barriers. Modular slotted beams also may be employed to accommodating differing widths and crowns of roadways.
