Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rail lubrication devices are sensitive to weather conditions and inefficiently distribute lubricants, leading to unreliable performance and environmental damage due to the remote application method and wide area distribution.
Innovation Solution
A device with a movable outlet that transitions between a remote and proximal position to the rail head, allowing precise application of lubricants directly to the rail head, reducing leakage and environmental impact while maintaining safety during vehicle movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the outlet is positioned at a remote distance from the rail head, then safety during vehicle movement is improved, but lubrication reliability and precision deteriorate due to weather sensitivity and wide area distribution
Solution Approach 1:
The outlet is designed to be movable between a retracted position (when no vehicle is present) and an extended position (when a vehicle is detected). This dynamic positioning allows the system to achieve close proximity lubrication for reliability while maintaining safety distance when idle, effectively resolving the contradiction between lubrication precision and safety.
Solution Approach 2:
A sensor system acts as an intermediary between the vehicle detection and outlet positioning. The sensor detects the approaching vehicle and triggers the outlet extension mechanism, enabling automatic adaptation to operational conditions and ensuring reliable lubrication delivery regardless of weather conditions.
2Reliability
If the outlet is positioned at a remote distance from the rail head, then safety during vehicle movement is improved, but lubrication precision deteriorates leading to wide area distribution and environmental damage
Solution Approach 1:
The movable outlet design enables precise target-oriented lubrication by extending close to the rail head only when needed. This eliminates wide-area spray distribution and reduces lubricant waste and environmental contamination while maintaining safety during vehicle movement.
3Measurement precision
If the outlet is moved into closer proximity to the rail head, then lubrication precision and reliability are improved, but safety risk during vehicle movement increases
Solution Approach 1:
The outlet dynamically adjusts its position based on vehicle presence detection. When a vehicle is detected, the outlet extends to achieve precise lubrication application. When no vehicle is present, the outlet retracts to maintain safety clearance. This dynamic behavior resolves the contradiction between precision and safety.
Solution Approach 2:
The system operates in periodic cycles: detecting vehicle approach, extending outlet for lubrication, then retracting after lubrication completes. This periodic extension and retraction ensures precise lubrication when needed while maintaining safety during idle periods.

AI summary
The present invention relates to a device for wetting or lubricating a rail head (7). The device has at least one outlet (30) for a wetting agent and/or lubricant. To ensure that the noise generated by a track-bound vehicle is reduced safely and regardless of the weather, a rail head-side end portion (33) of the at least one outlet (30) is movably mounted between a position at a remote distance from the rail head (7) and a position in closer proximity to the rail head.
