Solution Overview
Problem
Existing vehicle restraint systems for construction sites are cumbersome and costly to convert between different containment levels, requiring frequent assembly and disassembly, and are difficult to transport due to their large and bulky nature.
Innovation Solution
A modular vehicle restraint system featuring plug-in connections between base bodies and guide rails, allowing for easy assembly and disassembly, with tie rods and spacers for secure coupling, and optional weighting and friction-increasing means for enhanced stability and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If crash barriers are designed with high containment capacity and stability, then safety performance is improved, but transport and storage become more difficult due to large size and bulk
Solution Approach 1:
The crash barrier system is divided into separate modular components: base bodies and guide rails. These segments can be transported and stored independently in compact forms, then assembled on-site to create the complete barrier structure with high containment capacity.
Solution Approach 2:
The guide rails are designed to nest within or attach to the base bodies when not in use. The modular components can be stacked or nested together to minimize storage volume and transport space while maintaining the ability to assemble into a stable, high-capacity barrier system.
2Reliability
If crash barriers are designed as integrated units with high stability, then containment performance is improved, but assembly and conversion between different containment levels become time-consuming and costly
Solution Approach 1:
The barrier system is segmented into base bodies and guide rails that can be independently assembled. Different containment levels are achieved by adding or removing guide rails from the base bodies, allowing rapid conversion without time-consuming welding or permanent assembly.
Solution Approach 2:
The system transitions from static integrated units to a dynamic modular configuration. The base bodies serve as a permanent stable foundation, while guide rails can be dynamically added or removed to adjust containment levels based on site requirements, reducing assembly time for conversions.
3Strength
If crash barriers use traditional connection methods (welding or screwing), then structural strength is improved, but ease of assembly and disassembly deteriorates
Solution Approach 1:
The connection system is segmented into separate coupling elements that join base bodies and guide rails through simple insertion and locking mechanisms. This maintains structural strength while eliminating the need for welding or complex screwing operations, greatly improving assembly ease.
Solution Approach 2:
Traditional mechanical connections (welding, extensive screwing) are replaced with a simplified coupling mechanism involving insertion of coupling elements into receptacles and securing with minimal fastening. This substitution maintains connection strength while dramatically improving ease of assembly and disassembly.

AI summary
The invention relates to a vehicle restraint system for delimiting roadways, comprising guide beams (87) that are detachably placed next to each other. Each guide beam (87) comprises a housing-like base body (88) that can be arranged on the ground and a guide bar (98) disposed above the base body (88). On a first face (119) each base body (88) comprises an insertion pocket (120), and on another second face (121) it comprises an insertion flap (122). When two base bodies (88) are coupled to each other, the insertion flap (122) of the one base body (88) engages in the insertion pocket (120) of the adjoining base body. Pin-like projections (133), which engage in recesses (135) in the bottom web (134) of the insertion pocket (120), are provided on the bottom of the second face (121) of the base body (88).
