Solution Overview

Problem

Current lubrication methods for railroad tracks apply excessive amounts of lubricant, leading to unnecessary coating of rails and the surrounding environment, causing traction issues on inclined tracks and environmental contamination, while being costly and inefficient.

Innovation Solution

A system comprising a control module, a housing, and a lubricant distribution block with steel tubes, which applies a precise amount of lubricant just before train wheel contact using a lubricant distribution nozzle, reducing waste and environmental impact by minimizing lubricant usage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If lubricant is applied by a wayside lubrication system that pumps lubricant to a distribution bar with grooves, then lubrication coverage is achieved, but excessive amounts of lubricant are used and piled toward the top of the rail

Engineering Contradiction:
Improveamount of lubricantVSAvoidexcess lubricant waste
Core Design Contradiction:
Quantity of substanceVSLoss of substance

Solution Approach 1:

The distribution bar with multiple grooves is segmented into multiple distribution points along the rail. Each groove delivers lubricant to a specific location, allowing precise control of lubricant placement and preventing accumulation at the top of the rail. This segmentation enables the system to apply lubricant only where needed rather than creating excessive piles.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system applies lubricant with varying characteristics at different locations along the rail. Each distribution point delivers lubricant tailored to the specific local conditions and requirements of that section of the track, optimizing lubrication efficiency and reducing overall lubricant consumption by avoiding uniform excessive application.

Inventive Principle:
Principle #3Local quality

2Quantity of substance

If large amounts of grease are pumped to ensure coverage, then the small area needing lubrication is covered, but excess lubricant coats the entire rail and surrounding ground

Engineering Contradiction:
Improveamount of lubricantVSAvoidenvironmental contamination
Core Design Contradiction:
Quantity of substanceVSObject-affected harmful factors

Solution Approach 1:

The lubrication system is divided into multiple segmented distribution points along the rail, each delivering a controlled amount of lubricant only to the specific small area that requires it. This prevents the lubricant from spreading to the entire rail and surrounding ground, thereby reducing environmental contamination while ensuring adequate coverage of the needed areas.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system extracts and removes the harmful aspect of excessive lubricant application by using targeted distribution points that deliver lubricant only where absolutely necessary. This extraction of the problem (excess application) eliminates the harmful effects of lubricant migration to the surrounding environment while maintaining effective lubrication at the contact points.

Inventive Principle:
Principle #2Taking out (Extraction)

3Quantity of substance

If excess lubrication is applied to the rail, then coverage is ensured, but friction is reduced on inclined tracks where traction is needed

Engineering Contradiction:
Improveamount of lubricantVSAvoidtraction on inclined tracks
Core Design Contradiction:
Quantity of substanceVSReliability

Solution Approach 1:

The lubrication system is segmented into multiple targeted distribution points that apply lubricant only at specific locations where wheel-rail contact occurs. This prevents excess lubricant from coating the entire rail surface, particularly on inclined sections where traction is critical. The segmented approach ensures lubrication is provided where needed without compromising traction reliability on grades.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system applies lubricant with locally optimized characteristics at different positions along the rail. On inclined sections, the local quality of lubrication is controlled to maintain adequate traction while still providing protection at wheel contact points. This local quality control prevents the reduction of friction where traction is needed while maintaining lubrication where wear occurs.

Inventive Principle:
Principle #3Local quality

4Duration of action of stationary object

If repeated lubrication applications are performed over time, then continuous protection is maintained, but environmental impact is compounded

Engineering Contradiction:
Improvelubrication durabilityVSAvoidenvironmental impact
Core Design Contradiction:
Duration of action of stationary objectVSObject-affected harmful factors

Solution Approach 1:

The system uses segmented distribution points that deliver precise amounts of lubricant only where needed, reducing the total quantity applied with each lubrication event. This segmentation allows for repeated lubrication applications over time to maintain continuous protection while minimizing the cumulative environmental impact by avoiding excessive application at each interval.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The lubrication system operates periodically, applying small precise amounts of lubricant at scheduled intervals through the segmented distribution points. This periodic action with controlled quantities maintains the necessary lubrication durability for continuous protection while significantly reducing the cumulative environmental impact compared to repeated applications of excess lubricant.

Inventive Principle:
Principle #19Periodic action

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The system effectively reduces lubricant usage by applying it only where needed, minimizing environmental impact and saving costs by ensuring lubricant is carried by wheels immediately after application, rather than migrating to other areas.

Implementation Method 1

The only way to prevent such an occurrence is to apply lubrication to reduce cohesion

AI summary

An apparatus and system for applying lubricant to a rail road track having a control module, a housing, a lubricant distribution block, and a plurality of tubes for connecting the control module to the housing wherein the housing houses the lubricant distribution block. The control module is positionable in close proximity to the rail road track and the housing is positionable adjacent to and along a section of rail road track to be lubricated. The lubricant is stored in a vessel in the control module and pumped from the control module to a lubricant distribution nozzle connected to the housing and wherein sliding the lubricant distribution nozzle along the section of rail road track in a first direction distributes lubricant along the section of rail road track and then the block returns to a first position.
