Solution Overview

Problem

Existing railway wagon systems face challenges with the risk of breaking vertically operated jacks due to non-vertical load support and the potential for damage to cables and conduits during turning movements.

Innovation Solution

The introduction of a railway wagon design featuring a movable carrying section with a channel for conduits that automatically lowers mechanically during turning, and a beam assembly with a hydraulic cylinder actuator placed in parallel with the beam, allowing for secure ground support even on uneven surfaces.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a vertically operated jack is used to lower the ground support, then the support can be positioned on the ground to assist turning, but the risk of breaking increases when subjected to non-vertical loads from uneven ground

Engineering Contradiction:

Improveturning assistanceVSAvoidjack breaking risk

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

A pivoting arm is introduced as an intermediary between the vertically operated jack and the ground support. The jack maintains vertical operation while the pivoting arm transfers the force to the ground support at an angle, eliminating direct exposure of the jack to non-vertical loads from uneven ground.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The support system is divided into separate functional components: the vertically operating jack, the pivoting arm, and the ground support. This segmentation allows each component to perform its specific function optimally - the jack provides vertical force, the pivoting arm adapts to ground angles, and the support makes ground contact.

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If cables and conduits are routed along the platform, then they can provide necessary services, but they risk getting stuck or damaged during turning movements

Engineering Contradiction:

Improveservice provisionVSAvoidcable and conduit damage risk

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The conduits are moved from the horizontal platform surface to a vertical orientation within the channel structure. This dimensional change allows the conduits to remain stationary and protected while the platform turns underneath them, eliminating the risk of cables getting stuck or damaged during turning operations.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

3Productivity

If the carrying section is turned out for loading and unloading, then semitrailers can be loaded and unloaded, but the conduits extending between bogies are exposed to damage

Engineering Contradiction:

Improveloading and unloading efficiencyVSAvoidconduit protection

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

A channel structure serves as an intermediary that houses and protects the conduits during the turning operation. The channel is positioned to remain stationary or move independently from the carrying section, providing a protective pathway for conduits while the carrying section turns out for loading and unloading operations.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A railway wagon for semitrailers and the like has a first bogie, a second bogie and a carrying section therebetween. An elongated channel configured to receive conduits for air, hydraulics and/or electronics extends between the two bogies. The media channel is lowered in a mechanical way when the carrying section is turned out to a loading/unloading position.
