Rail Line Distributor for Real-Time CHFC Application
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing rail lubrication systems face a time lag in distributing Composite Heavy Fluid Compound (CHFC) from the pump to the point of application, leading to performance issues and increased maintenance costs due to the remoteness of distribution devices and the use of flat guides that can damage wheel surfaces.
Innovation Solution
A line distributor is positioned directly next to the rails with reduced dosage tubes and rounded guides to ensure real-time, accurate application of CHFC, reducing time lag and minimizing wheel damage, and is driven by mini pumps activated by approaching wheels to apply the compound for enhanced friction and noise reduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If distribution devices are positioned remotely from the point of application, then the device structure is simpler and easier to install, but the time lag for material delivery increases and performance deteriorates
Solution Approach 1:
The distribution system is segmented into multiple dosing locations along the rail, with individual dosing tubes positioned at specific intervals. This allows the distribution function to be distributed along the rail length, reducing delivery time to each point while maintaining manageable device complexity through modular segmentation.
Solution Approach 2:
The distribution device transitions from a centralized remote position to a linear distribution along the rail dimension. By positioning dosing tubes at multiple locations along the rail length, the system eliminates the time lag associated with remote centralized distribution while managing complexity through spatial distribution rather than concentration.
2Object-affected harmful factors
If flat guides are used in the applicator, then the device structure is simpler, but wheel surface damage occurs and maintenance costs increase
Solution Approach 1:
The flat guides are replaced with rounded guides having circular or elliptical cross-sections. This curvature eliminates sharp edges that cause wheel surface damage, reducing harmful factors while the simple rounded geometry maintains ease of manufacture and structural simplicity.
Solution Approach 2:
The guide geometry parameter changes from flat (planar) to rounded (curved cross-section). This parameter modification eliminates the damaging sharp edges while maintaining structural simplicity, directly addressing the wheel surface damage issue without significantly increasing device complexity.
3Loss of time
If dosage tubes are made long to reach distant application points, then the distribution device can be positioned remotely, but the time lag for material delivery increases
Solution Approach 1:
The single long dosage tube approach is segmented into multiple shorter dosage tubes positioned at different locations along the rail. Each tube serves a specific dosing location close to the point of application, eliminating the need for long tubes while reducing delivery time through localized positioning.
Solution Approach 2:
The dosage tube system transitions from long tubes extending remotely to multiple short tubes distributed along the rail dimension. This spatial distribution along the rail length allows each tube to be short while collectively covering the required application points, eliminating time lag without requiring long tubes.
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 solution enables efficient, real-time application of CHFC, reducing noise and wear, minimizing material waste, and lowering maintenance costs by ensuring precise and gentle contact with the wheel surfaces.
Implementation Method 1
The distributors in general are devices used for distribution and dosage of medium onto the wheel of the rail vehicle which is approaching part of the rails with additional friction between wheel flank and rail or some other device such as rail switch, rail brake, lead rail or some other device.
Implementation Method 2
The advantage of elliptic, preferably round guides (in this patent application also guide tube expression is used) is to provide for 'softer' (i.e. less bumpy) transfer of wheels through the distributor, as well as providing for decrease of waste of material into gravel bed
Implementation Method 3
The medium for purposes of this application in this case is means for spreading around the wheel and it does not necessarily mean means for lowering of a friction coefficient - in fact it may even mean means for increase of said friction coefficient.
Implementation Method 4
the medium adds to increase of friction coefficient while adding to decrease of noise between rail brake and wheel flank during braking

AI summary
Technical problem of time lag between start of operation and application of medium onto the rail vehicle wheel 's flank is solved by line distributor, preferably for anti-noise device for rail brakes wherein the line distributor is positioned directly next to rails to provide for accurate dosage in real time and in required-desired quantity. In such a case the dosage tubes are reduced to the length enabling correct operation of an applicator. The device is preferably used for application of anti-noise material onto wheel's flanks of rail vehicles. In addition flat guides of the applicator are replaced with guides with rounded, preferably essentially elliptical, more preferably essentially circular cross section so the edges of damaged wheels do not transfer shocks onto the device. The distributors in general are devices used for distribution and dosage of medium onto the wheel of the rail vehicle which is approaching part of the rails with additional friction between wheel rim and rail or some other device such as rail switch, rail brake, leading rail or some other device. The medium for purposes of this application in this case is means for spreading around the wheel's flank and it does not necessarily mean means for lowering of a friction coefficient - in fact it may even mean means for increase of said friction coefficient. Said lubricant according to this invention is preferably very complex Composite Heavy Fluid Compound (CHFC).
