Continuous Metallic Screen for Motorcyclist Safety Barriers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current metallic safety barriers are inadequate in protecting motorcyclists during collisions, as they often result in severe injuries due to direct impact with the barrier or penetration, and existing protection systems are inefficient in preventing such incidents, especially when the distance between posts exceeds 2 meters, leading to potential entanglement and high vertical compression forces on the neck.
Innovation Solution
A continuous metallic system comprising a flat-trapezoidal screen with a protuberance directed towards the traffic side, suspended by support arms and intermediate arms with clamps, which reduces the risk of entanglement and deformation, and features vertical ribs for increased stiffness, preventing excessive transversal deformation and minimizing neck compression forces.

1Object-affected harmful factors
If a continuous metallic screen is suspended by support arms to protect motorcyclists, then protection against direct impact is improved, but the risk of entanglement and penetration increases when the distance between posts exceeds 2 meters
Solution Approach 1:
The continuous metallic screen is divided into multiple segments or panels that can deform independently during impact. This segmentation allows the screen to absorb impact energy through controlled deformation of individual segments while maintaining overall structural integrity, preventing both direct impact transmission and entanglement risks associated with long-span continuous structures
Solution Approach 2:
The support arms are designed with controlled deformation capabilities, allowing them to flex and absorb impact energy dynamically during motorcyclist collisions. This dynamic response reduces the rigid impact forces transmitted to motorcyclists while the arms return to their original position, preventing entanglement and maintaining protection effectiveness over time
2Device complexity
If the distance between posts is increased to reduce device complexity, then installation and maintenance become easier, but the screen experiences excessive deformation and entanglement risks
Solution Approach 1:
The metallic screen is designed as a flexible yet strong structure that can deform controllably under impact loads. This flexibility allows the screen to accommodate larger distances between support arms without excessive deformation, reducing the number of required posts and support arms while maintaining stability and preventing entanglement through controlled energy absorption
3Device complexity
If existing protection systems are used to reduce device complexity, then installation becomes easier, but they fail to prevent severe injuries due to direct impact and penetration
Solution Approach 1:
The metallic screen is positioned and designed to provide cushioning protection before impact occurs, creating a protective barrier that absorbs and distributes impact energy. The screen's design includes features that anticipate motorcyclist impact trajectories and provide energy absorption in advance, preventing severe injuries by reducing impact forces before they reach the motorcyclist
