Solution Overview
Problem
Existing barrier systems with flexible rails and rigid post bases are susceptible to shearing or deformation near the posts during impacts, compromising structural integrity and component damage.
Innovation Solution
The integration of flexible rails with rigid post bases through a combination of rods, sleeves, and anchors that transfer shear impacts to the ground, utilizing metal-to-metal connections and reinforced structures to enhance stability and prevent deformation.

1Loss of energy
If flexible rails are used in barrier systems, then the barrier can absorb impact energy through deformation, but the rails are susceptible to shearing or deformation near the posts during impacts
Solution Approach 1:
The patent applies local quality by making the post bases more rigid than the rails themselves. The post bases are designed with higher structural strength and stiffness to provide stable support points, while the rails maintain flexibility for energy absorption. This localized differentiation of mechanical properties allows the system to both absorb impact energy and resist shearing at critical connection points.
Solution Approach 2:
The barrier system uses composite construction by combining flexible rail materials with rigid post base materials. The rails may be made of flexible metal or polymer, while the post bases use rigid metal construction with reinforced structures. This composite approach allows each component to perform its optimal function - flexible rails for energy absorption and rigid bases for structural stability.
2Stability of the object's composition
If rigid post bases are used to support flexible rails, then structural stability is enhanced, but shear impacts can cause deformation or damage at the connection points
Solution Approach 1:
The post bases incorporate cushioning or energy-absorbing features designed to mitigate shear impacts before they propagate through the rigid structure. This may include deformable connection elements, damping materials, or geometric features that absorb and dissipate shear energy, protecting the rigid post base from damage while maintaining overall stability.
Solution Approach 2:
The patent introduces intermediary elements between the rigid post bases and flexible rails that serve as mediators for shear impact forces. These intermediaries may be specialized connection pieces, mounting brackets, or transition elements that accommodate shear forces through controlled deformation or friction, protecting both the rigid base and flexible rail from damage.

AI summary
Methods, apparatus, systems, and articles of manufacture for barrier systems with impact resistant rails supported from floor mounted post bases are disclosed. An apparatus includes an outer body of a post to extend upward from a ground, the post to be anchored to the ground; a rail to extend through an opening in a wall of the outer body; and a rod to extend upward from the ground within the outer body, the rod to extend through a hole in the rail.
