Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing concrete safety barriers are inadequate for vehicles of different masses, as they are designed for specific impact energies and lack sufficient restraining effect, especially for lower impact energies, and are not easily adaptable for various road users.
Innovation Solution
A modular concrete barrier design featuring a first wall with laterally projecting supports and a second wall with a receptacle, allowing for adjustable stability and energy absorption through a gap with a damping element, and optionally a third wall for enhanced traffic deflection, along with tension members to connect wall elements and prevent offset hazards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wall elements are designed for a certain level of impact energy, then the barrier provides sufficient restraining effect for that energy level, but it represents an essentially rigid wall for lower impact energies and has an insufficient restraining effect for higher impact energies
Solution Approach 1:
The barrier is divided into a first wall and a second wall that can be independently positioned. The second wall can be locally displaced relative to the first wall, creating a segmented structure that adapts to different impact energies. For lower energies, only the second wall moves; for higher energies, both walls move together, providing progressive restraint.
Solution Approach 2:
The barrier transitions from a static rigid structure to a dynamic system where the second wall can be locally displaced by a predeterminable distance. This dynamic capability allows the barrier to absorb impact energy through controlled movement while maintaining adaptability to different vehicle masses and impact scenarios.
2Stability of the object's composition
If a continuous concrete barrier is formed with connected wall elements, then the barrier provides structural integrity, but it cannot be easily adapted for various road users and impact energy levels
Solution Approach 1:
The barrier system is segmented into a first wall and a second wall that are not rigidly connected. The second wall can be locally displaced relative to the first wall, allowing the structure to maintain integrity while adapting to different impact scenarios and road user requirements.
Solution Approach 2:
The barrier design provides multi-functionality by combining a permanent first wall with a movable second wall. This universal design can handle various impact energy levels and serve different road user protection needs, from low-energy car impacts to high-energy truck impacts, within a single barrier system.
3Adaptability or versatility
If the barrier uses a modular design with separable wall elements, then it can be easily adapted for different applications, but it may reduce stability and structural integrity
Solution Approach 1:
The modular design segments the barrier into a first wall and second wall that can be independently positioned and configured. This segmentation enables easy adaptation to different applications while maintaining stability through the defined spatial relationship and predeterminable gap between the two walls.
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 design provides reliable traffic deflection for various impact energies, enhances stability and noise protection, and allows for easy adaptation to different road users, ensuring effective restraint and protection against loose parts and noise.
Implementation Method 1
a damping element is arranged in the gap. The damping element can ensure a controlled displacement of the second wall in the event of an impact and vibrations can be avoided. Furthermore, part of the impact energy can be dissipated by the damping element.

AI summary
The aim of the invention is to increase safety of a concrete safety barrier (1). For this purpose, a first wall (11) comprises first concrete wall elements (2) with a concrete base (21). A second wall (12) comprising second concrete wall elements (3) is configured at least on a first face (24) of the first wall (11), said second wall (12), on the face (34) facing away from the first wall (11), being configured as a traffic barrier. A preset gap is configured between the first wall (11) and the second wall (12). The first wall (11) is provided as a reinforcing element of the second wall (12) when the second wall (12) is locally displaced and/or locally tilted by a preset distance.
