Traffic Barrier Mounting Assembly with Controlled Displacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing traffic barrier mounting assemblies fail to securely anchor traffic barriers to the ground, leading to displacement and potential breakage during vehicle collisions, which can cause uncontrolled positioning and increased risk of injury or damage.
Innovation Solution
A mounting assembly with a stationary attachment base and ground connecting element, coupled by means that allow controlled movement perpendicular to the traffic barrier's longitudinal axis, enabling the barrier to absorb energy and reduce impact forces by allowing limited displacement and deformation, thus enhancing safety and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the traffic barrier is firmly fixed to the ground using mounting assemblies, then the barrier can withstand impact forces, but the mounting assemblies may break or come loose during vehicle collisions, causing the barrier to become uncontrolled
Solution Approach 1:
The mounting assembly incorporates a coupling mechanism between the attachment base and ground connecting element that permits controlled movement during impact. This dynamic capability allows the barrier to absorb impact energy through controlled displacement while maintaining connection integrity, preventing both breakage and uncontrolled displacement
Solution Approach 2:
The coupling means allows the mounting assembly to change its mechanical parameters during impact, transitioning from a rigid fixed state to a controlled movement state. This parameter change enables the system to adapt to impact forces by allowing limited displacement while maintaining overall structural integrity
2Stability of the object's composition
If the traffic barrier is rigidly fixed to prevent displacement, then positioning stability is improved, but the barrier cannot absorb impact energy, increasing the risk of breakage and uncontrolled positioning
Solution Approach 1:
The coupling mechanism provides controlled movement capability that allows the barrier to dynamically respond to impact forces. The attachment base and ground connecting element can move relative to each other within defined limits, enabling energy absorption while maintaining stable positioning during normal conditions
Solution Approach 2:
The coupling means is designed to allow controlled movement that acts as a cushion during impact. This pre-configured movement capability absorbs impact energy before it can cause breakage or uncontrolled displacement, protecting the barrier structure
3Strength
If the mounting assembly allows movement to absorb impact energy, then breakage risk is reduced, but the barrier may displace or turn over, preventing correct functioning
Solution Approach 1:
The coupling mechanism provides controlled dynamic movement within defined limits. The attachment base and ground connecting element can move relative to each other to absorb impact energy, but the movement is constrained to prevent excessive displacement or overturning that would compromise barrier functionality
Solution Approach 2:
The system changes its mechanical parameters during impact by allowing controlled movement, but these parameter changes are bounded within limits that maintain positioning control. The coupling means enables parameter change for energy absorption while preventing parameter changes that would cause loss of function
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 solution effectively secures the traffic barrier while allowing controlled movement to absorb energy, reducing the risk of breakage and physical harm, predicting impact outcomes, and minimizing the chance of the barrier tumbling over, thereby enhancing safety for vehicle passengers and others.
Implementation Method 1
the coupling means are configured to allow only a linear relative movement of the attachment base and the ground connecting element, the traffic barrier is able to move along a linear path... allowing for movement of the traffic barrier with respect to the ground/the ground connecting element up to a certain extend... lengthening the time over which the vehicle's momentum is changed while absorbing energy
