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

VSEngineering 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

Engineering Contradiction:
Improvestructural stabilityVSAvoidassembly and dismantling time
Core Design Contradiction:
Stability of the object's compositionVSLoss of time

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.

Inventive Principle:
Principle #1Segmentation

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.

Inventive Principle:
Principle #15Dynamics

2Productivity

If portable track barriers use detachable support elements for quick assembly, then assembly speed is improved, but structural stability deteriorates

Engineering Contradiction:
Improveassembly speedVSAvoidstructural stability
Core Design Contradiction:
ProductivityVSStability of the object's composition

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.

Inventive Principle:
Principle #10Preliminary action

3Loss of time

If portable track barriers are designed for rapid deployment, then response time is improved, but adaptability to track geometry deteriorates

Engineering Contradiction:
Improvedeployment timeVSAvoidadaptability to track geometry
Core Design Contradiction:
Loss of timeVSAdaptability or versatility

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.

Inventive Principle:
Principle #15Dynamics

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.

Inventive Principle:
Principle #35Parameter changes
