Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable track barriers for rail safety require laborious dismantling and reassembly, hindering quick access to the track during emergencies or operational needs, and do not efficiently adapt to varying track geometries.
Innovation Solution
A portable track barrier design featuring articulated connections between linear components, allowing for rapid conversion between a vertically erected and flat configuration, with a locking mechanism that enables secure attachment to rails and easy adjustment to compensate for track geometry variations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If portable track barriers use fixed rigid support elements attached to rails, then structural stability is improved, but assembly and dismantling time increases
Solution Approach 1:
The support element is divided into two separable parts: a first linear component that attaches to the rail and a second linear component that forms the barrier structure. These components can be quickly connected and disconnected without full dismantling, resolving the contradiction between stability and quick assembly/disassembly.
Solution Approach 2:
The barrier introduces dynamic functionality through articulation points that allow the second linear component to pivot between a vertical barrier position and a horizontal stowed position. This dynamic capability enables rapid configuration changes while maintaining structural integrity when deployed.
2Productivity
If portable track barriers use detachable support elements for quick assembly, then assembly speed is improved, but structural stability deteriorates
Solution Approach 1:
The first linear component is pre-equipped with attachment mechanisms that interface with standard rail components. This preliminary preparation allows workers to quickly attach the component to the rail without complex assembly procedures, maintaining both speed and stability.
3Loss of time
If portable track barriers are designed for rapid deployment, then response time is improved, but adaptability to track geometry deteriorates
Solution Approach 1:
The articulation points enable the barrier to dynamically adapt to various track geometries including curves and gradients. The second linear component can pivot to maintain proper barrier orientation while the attachment mechanism remains fixed to the rail, achieving both rapid deployment and geometric adaptability.
Solution Approach 2:
The barrier system allows for parameter adjustments in the attachment position along the rail and the articulation angle of the second linear component. These parameter changes enable the same barrier design to adapt to different track geometries without requiring multiple specialized components.

AI summary
Portable track barrier (1) for separating a spatial area from a danger zone adjacent to the spatial area of a track (100) having at least two parallel rails (110, 120), comprising at least one support element (2) which has a first (10) and a second (20) strand-shaped component, both of which are connected to each other, wherein the first component has two ends (15, 16), wherein a joining mechanism (60) for detachably fixed attachment to the rail is attached to the first end and the second end is connected to the second component, and wherein at least one holding device (40, 41) is attached to the second component, which supports at least one strand-shaped element (3, 4) with a strand-shaped longitudinal extension, wherein the first component and the second component are connected to a locking mechanism (50) via a hinge connection (30),and that the joint connection, in a disengaged state of the locking mechanism, allows the second component to pivot about a pivot axis (S) relative to the first component, which is oriented parallel to a first strand longitudinal extension (A1) attributable to the first strand-shaped component.
