Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional anti-ram systems are installed on paved surfaces, then they can provide effective vehicle stopping capability, but they require extensive site preparation and excavation
Solution Approach 1:
The anti-ram system is divided into modular bollard sections that can be independently installed on existing surfaces. Each section comprises a base and multiple bollards that can be assembled without requiring extensive excavation or site preparation, while still providing effective vehicle stopping capability through distributed impact resistance
Solution Approach 2:
The system transitions from traditional deep-mount installations to surface-mount configurations, changing the installation dimension from vertical excavation to horizontal surface placement. This allows the system to be installed on existing paved surfaces without requiring underground excavation, while maintaining stopping capability through the distributed modular structure
2Reliability
If fixed anti-ram systems are used, then they provide consistent stopping performance, but they cannot adapt to varying terrain and angular configurations
Solution Approach 1:
The system incorporates adjustable and reconfigurable modular sections that can be adapted to different terrain conditions and angular configurations. The bollard sections can be positioned and connected in various arrangements to match the specific requirements of different installations, while maintaining consistent stopping performance through standardized connection mechanisms
Solution Approach 2:
The modular bollard sections are designed with universal connection interfaces that allow the same basic unit to be installed in multiple configurations and terrains. The system can accommodate various angular arrangements and terrain conditions using the same standardized components, providing both adaptability and performance consistency
3Reliability
If modular bollard sections are interconnected, then the system achieves desired stopping distances, but the system complexity increases
Solution Approach 1:
The system divides the anti-ram barrier into standardized modular sections that can be independently manufactured and installed. Each module is designed with standardized connection interfaces that simplify the assembly process, allowing multiple sections to be interconnected to achieve desired stopping distances without proportionally increasing overall system complexity
Solution Approach 2:
The system achieves varying stopping distances by changing the number and arrangement of modular sections rather than redesigning the entire system. Standardized connection parameters and modular dimensions allow for straightforward configuration adjustments to match different stopping distance requirements while maintaining consistent installation procedures
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 system provides an adaptable and efficient means to stop vehicles by distributing the impact across interconnected bollard sections, achieving desired stopping distances without the need for extensive excavation or site preparation, while allowing for easy deployment and reconfiguration.
Implementation Method 1
high friction structure secured to a bollard section or sections and/or to a connector or connectors to inhibit sliding of the system after an impact

AI summary
Disclosed anti-ram systems comprise at least one bollard section comprising a base of limited height and a plurality of spaced bollards extending upwardly from the base, which may be erected or installed on a paved surface such as asphalt, concrete, paver stones, etc., or on an unpaved surface such as soil, and need not be partially of fully buried, and yet can qualify for Department of State crash ratings previously assigned to buried bollard systems. Disclosed anti-ram systems also comprise a plurality of bollard sections and one or more connectors for interconnecting two or more of the bollard sections, and may also include an anchor or anchor system engaging at least each end of a bollard section not connected to another bollard section. The bollard sections may be filled with ballast and high friction structure may be attached to the bottom of the bollard sections to resist sliding after impact.
