Solution Overview

Problem

Existing track-securing devices for rail barriers face challenges in maintaining stability and ease of installation, especially when increasing the distance from the rail, due to varying ground levels and surface materials, which complicates positioning and requires significant effort.

Innovation Solution

A track-securing device with a slide mechanism mounted on the retaining limb, featuring a support element that protrudes to stabilize the device on the railway sleeper, allowing for adjustable positioning and easy installation by sliding along the retaining limb, thereby maintaining stability and ease of use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the distance of the bar holder from the rail is increased to improve safeguarding, then the safety of the rail section is improved, but the positioning stability of the bar holder becomes worse

Engineering Contradiction:
Improvesafeguarding effectivenessVSAvoidpositioning stability
Core Design Contradiction:
ReliabilityVSStability of the object's composition

Solution Approach 1:

The slide acts as an intermediary component between the retaining limb and the railway sleeper. It provides a stable support interface that mediates the connection, allowing the bar holder to be positioned at a greater distance from the rail while maintaining stability through the slide's contact with the sleeper.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If the ground level and ground surface material near the rail vary considerably, then the adaptability to different terrains is improved, but the ease of installation and positioning of the track-securing device becomes worse

Engineering Contradiction:
Improveterrain adaptabilityVSAvoidinstallation ease
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The slide is designed to be displaceable along the retaining limb, providing dynamic adjustability. This allows the track-securing device to be easily positioned on varying ground levels and surface materials without requiring complex adjustment mechanisms, maintaining ease of installation while adapting to different terrains.

Inventive Principle:
Principle #15Dynamics

3Stability of the object's composition

If a support element is added to the retaining limb to improve positioning stability, then the positioning stability is improved, but the device complexity increases

Engineering Contradiction:
Improvepositioning stabilityVSAvoidstructural complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The support element is merged with the slide component rather than being a separate addition to the retaining limb. This integration combines the support function with the existing sliding mechanism, improving positioning stability while minimizing increases in device complexity.

Inventive Principle:
Principle #5Merging (Combining)
