Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle restraint systems are inflexible and costly to convert between different containment levels, and they are cumbersome for transportation due to their large and bulky design, requiring significant time and space for assembly and shipping.
Innovation Solution
A modular vehicle restraint system where crash barriers are detachably connected via tie rods and spacers, allowing for easy assembly and disassembly, enabling flexible adaptation to varying containment levels and efficient transportation by separating base bodies and guide rails for stacking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If crash barriers are designed as integrated units with guide rails permanently attached to base bodies, then structural strength and stability are improved, but transport efficiency and assembly flexibility deteriorate due to large size and inability to stack
Solution Approach 1:
The crash barrier system is divided into separate modular components: base bodies and guide rails that can be detached from each other. The base bodies can be stacked on top of each other for efficient transport, while guide rails can be attached only when needed at the construction site. This segmentation resolves the contradiction by allowing compact transport configuration and functional assembly configuration.
2Stability of the object's composition
If crash barriers are designed as integrated units with permanent connections, then structural stability is improved, but adaptability to different containment levels deteriorates due to inability to modify configuration
Solution Approach 1:
The connection between base bodies and guide rails is made dynamic through detachable coupling mechanisms. Base bodies can be coupled to guide rails using coupling elements that allow easy attachment and detachment. This enables the system to be reconfigured from single-level to multi-level containment structures as project requirements change, while maintaining structural stability when assembled.
3Strength
If crash barriers use complex welding or permanent fastening connections between guide rails and base bodies, then connection strength is improved, but assembly time and conversion costs deteriorate
Solution Approach 1:
The patent replaces complex welding or permanent fastening systems with a mechanical coupling system using coupling elements, threaded rods, and form-fitting connections. These mechanical fasteners can be quickly assembled and disassembled with simple tools, providing sufficient connection strength while dramatically reducing assembly and conversion time compared to welding operations.
4Reliability
If crash barriers are designed with fixed configuration for high containment levels, then containment capacity is improved, but transport space efficiency deteriorates due to bulky design
Solution Approach 1:
The system is segmented into base bodies that can be stacked vertically during transport, significantly reducing the volume occupied. Guide rails and other containment components are attached only when needed at the destination, allowing the transport configuration to be compact while the assembled configuration provides the required high containment capacity.

AI summary
The invention relates to a vehicle restraint system for delimiting roadways, said system consisting of guiding profiles (1) which are placed next to one another in a detachable manner. Each guiding profile (1) comprises a housing-type base body (2) that can be placed upright on the ground and a guiding bar (14) arranged above the base body (2). The guiding bar (14) and the base body (2) can be coupled together by means of tightening rods (19), wherein each tightening rod (29) is connected to the guiding bar (14) with one upper end (20) and can be tightened at one bottom end (22) in an abutment (23) arranged in the base body (2). The guiding bar (14) and the base body (2) are advantageously arranged at a vertical distance from one another by spacer elements (30), the tightening rod (19) extending through said spacer elements (30).
