Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle barrier systems require large, heavy concrete blocks and extensive digging, leading to inefficient and costly installation processes.
Innovation Solution
A security system with a barrier comprising a first and second support element and an elongated carrier element positioned below ground level, supported by plate-shaped elements that reduce the depth of excavation, combined with upwardly extending stanchions for vehicular impact resistance, allowing for a modular and flexible design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If large concrete blocks are used to provide sufficient strength, then the barrier strength is improved, but the excavation depth and installation complexity increase
Solution Approach 1:
The barrier system is divided into modular components: horizontal carrier elements positioned at different depths, vertical support elements, and connecting members. This segmentation allows each component to be optimized independently and simplifies installation compared to monolithic concrete blocks.
Solution Approach 2:
The invention transitions from vertical placement of concrete blocks to a three-dimensional configuration with horizontal carrier elements at multiple depth levels. This dimensional change distributes the structural function across multiple levels, reducing the need for deep excavation while maintaining strength.
2Strength
If concrete blocks of considerable size are used, then the barrier strength is improved, but the material usage and cost increase
Solution Approach 1:
The barrier system combines different materials with complementary properties: horizontal carrier elements (metal or composite), vertical support elements (metal), and connecting members. This composite approach provides high strength-to-weight ratio compared to monolithic concrete blocks.
Solution Approach 2:
By segmenting the barrier into modular components positioned at different depths, the system achieves the required strength with less total material volume. Each segment contributes to the overall structural integrity without requiring excessive material in any single location.
3Stability of the object's composition
If deep excavation is performed to install concrete blocks, then the barrier stability is improved, but the installation time and cost increase
Solution Approach 1:
The system uses partial excavation only where needed for positioning horizontal carrier elements at specific depth levels, rather than requiring deep excavation throughout. This partial action approach maintains stability while significantly reducing installation time.
Solution Approach 2:
The modular segmented design allows for staged installation where horizontal carrier elements can be positioned at different depths independently, reducing the overall excavation depth required and enabling faster installation compared to monolithic concrete block systems.
4Strength
If traditional concrete block systems are used, then the barrier strength is improved, but the adaptability to different configurations decreases
Solution Approach 1:
The barrier system consists of standardized modular components (horizontal carrier elements, vertical support elements, connecting members) that can be configured in various arrangements. This segmentation provides high adaptability to different site requirements while maintaining structural strength through consistent connection methods.
Solution Approach 2:
The horizontal carrier elements serve multiple functions: providing structural support, defining barrier depth levels, and serving as attachment points for vertical support elements. This multi-functionality increases configuration adaptability without compromising strength.

AI summary
The present invention provides a security system providing a barrier above a ground level. The security system comprises a first support element extending in a first direction and a second support element extending in a second direction, where the first support element and the second support element are substantially plate-shaped and arranged below ground level. The security system further comprises an elongated carrier element extending in a third direction, where the third direction is transverse to the first direction and the second direction. The first support element and the second support element are attached to a lower surface of the elongated carrier element to provide support for the elongated carrier element, where both the first support element and the second support element extend away from the elongated carrier element on opposite sides of the elongated carrier element, and where the elongated carrier element is arranged below ground level. The security system further comprises at least one elongated stanchion extending upwardly from an upper surface of the elongated carrier element from a point below ground level to a point above ground level. The at least one stanchions is removably attached to the elongated carrier element.
