Retractable Security Barrier With Movable Post
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing security barriers face challenges such as trapping hazards and deep foundation requirements, which can interfere with underground services and increase safety risks, while also being costly and complex.
Innovation Solution
A security barrier apparatus with at least three upright posts, where two are fixed and one is translatably movable, allowing for deployment and retraction without a ground foundation, reducing the risk of trapping and interference with underground services, and featuring a slide device for operation between open and closed positions to control vehicle passage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a pivotable security bollard is used between vertical and horizontal positions, then the barrier can be deployed and retracted, but it forms a trap hazard with the ground creating a safety risk
Solution Approach 1:
Instead of the bollard pivoting down to the ground (creating a trap hazard), the bollard is designed to be retractable into the housing, inverting the traditional movement pattern. The bollard moves vertically into the housing rather than horizontally along the ground, eliminating the trap hazard while maintaining deployment capability
Solution Approach 2:
The harmful interaction between the bollard and ground is eliminated by extracting the bollard into the housing when not in use. The bollard is completely removed from the operational space and stored within the housing structure, preventing any contact with the ground that could create trapping hazards
2Strength
If a deep foundation housing is used for the movable bollard, then the barrier can be securely mounted, but it interferes with underground services such as power lines, drains, or communication cables
Solution Approach 1:
The housing is designed with a shallow depth dimension that accommodates the retractable bollard mechanism without requiring deep underground installation. By changing the dimensional approach from deep vertical embedding to shallow surface mounting with internal retraction, the system maintains structural security while avoiding interference with underground services
Solution Approach 2:
The bollard transitions from a static deeply-mounted structure to a dynamic retractable system. The bollard can be inserted into and retracted from the housing as needed, providing secure mounting when deployed while allowing the housing to remain shallow and non-intrusive to underground infrastructure
3Object-affected harmful factors
If a telescopic post is used to reduce foundation depth, then the barrier becomes less of a safety hazard, but it increases cost and complexity
Solution Approach 1:
The barrier system is segmented into distinct functional components: a stationary housing that provides secure mounting and a separate movable bollard that can be independently deployed and retracted. This segmentation allows each component to be optimized for its specific function while reducing overall system complexity compared to a fully telescopic design

AI summary
The invention relates to a security barrier apparatus 10, 70, 100 comprising a support 12 having at least three upright posts 14, 16, 18, 72 thereon. Two of the posts 14, 18 being fixed to the support 12 and at least one post 16, 72 being translatably movable relative to the two fixed posts 14, 18. The two fixed posts 14, 18 being spaced apart from one another and comprise a first plane 19 therebetween. The movable post 16, 72 being mounted to a slide device 24 of the support 12 for providing said translatable movement. The slide device 24 to operate the apparatus 10, 70 between an open position and a closed position such that in the closed position the movable post 16, 72 is between the fixed posts 14, 18 for inhibiting the passage of a vehicle, and in the open position the movable post 16, 72 is out of alignment with the first plane 19 and adjacent to one of the fixed posts 14, 18 for allowing the passage of a vehicle therebetween.
