Modular Bollard Foot and Collar Assembly for Impact Dispersion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for installing vehicular impact barriers using bollards are costly, time-consuming, and damaging to ground surfaces, especially when temporary placement is required, as they often necessitate excavation, which can compromise structural integrity and is not feasible in all situations, such as elevated floors or areas with obstacles.
Innovation Solution
A bollard apparatus comprising one or more bollard members fixed to separate foot members that can engage the ground with a large interface area, featuring a collar member that circumscribes the bollard and a flexible coupling line system to transmit impact forces across multiple foot members, allowing for efficient absorption and dispersion of impact energies without the need for extensive excavation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If bollards are permanently embedded in the ground through excavation, then the barrier provides sufficient robustness and resilience, but the process is costly, time-consuming, and damaging to existing ground surfaces
Solution Approach 1:
The bollard system is divided into separate components: a bollard member, a foot member for ground engagement, and a collar member for connection. This segmentation allows the bollard to be installed without extensive excavation, as the foot member can be placed on or shallowly embedded in the ground surface, reducing installation cost and time while maintaining barrier robustness
Solution Approach 2:
The invention extracts the deep embedding requirement from the traditional bollard installation process. By using a foot member with a large interface area that engages the ground surface without excavation, the system removes the harmful excavation step while preserving the structural reliability of the barrier through the collar-bollard-foot assembly
2Reliability
If bollards are permanently embedded in the ground, then the barrier is fixed and robust, but removal requires re-excavation and repair of ground surfaces
Solution Approach 1:
The bollard system transitions from a static embedded structure to a dynamic, removable assembly. The collar member provides a secure connection that can be assembled and disassembled without excavation, allowing the barrier to be easily removed and repositioned while maintaining its robustness during use. This dynamic design eliminates the need for re-excavation and surface repair upon removal
3Strength
If excavation is required for bollard installation, then robust bollards can be embedded, but existing structural integrity may be compromised and embedding may not be feasible in all situations
Solution Approach 1:
The foot member with its large interface area design allows the bollard system to function universally across different ground surfaces including paved areas, elevated floors, and surfaces with obstacles. The collar member provides a standardized connection interface that adapts to various installation scenarios without requiring excavation, making the system feasible in situations where traditional embedding would compromise structural integrity or be impossible

AI summary
A bollard apparatus for use as a vehicle barrier including one or more bollard members, and one or more separate foot members each adapted for ground engagement by placement upon (or shallow-mount embedment within) a ground or floor surface. To each of the foot members is fixed at least one bollard member upstanding therefrom. At least one collar member is positioned within a respective through-opening in a respective foot member wherein the collar member is fixed to the base end of a bollard member and circumscribes the bollard member thereat. The collar member is upstanding from the surface of foot member from which the bollard number is also upstanding.
