Rail Vehicle Cleaning Robot With Dirt Detection and Targeted Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rail vehicles are frequently damaged by spray paint or graffiti, leading to connection failures if windows in the driver's cab area become dirty, rendering the vehicle unfit for use, and existing cleaning technologies are not efficient for quick and reliable automatic cleaning.
Innovation Solution
A cleaning device equipped with detection and checking devices, including light sensors or optical detectors, and multi-axis robots that create and execute cleaning programs to automatically detect, clean, and verify the cleanliness of rail vehicles, using various cleaning elements like dry ice or chemical liquids, with optional fully automated movement control to facilitate efficient cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual cleaning methods are used for rail vehicles, then flexibility and adaptability to different soiling levels are maintained, but cleaning efficiency and speed are insufficient
Solution Approach 1:
The detection device scans the rail vehicle before cleaning to identify soiling locations and extent, creating a cleaning program in advance. This preliminary detection and planning enables the cleaning device to execute precise, high-speed automated cleaning without manual intervention during the actual cleaning process.
Solution Approach 2:
Manual cleaning operations are replaced by an automated cleaning device that uses detection devices, control devices, and multi-axis robots. The system substitutes human mechanical cleaning actions with automated mechanical systems guided by optical detection and computer control, dramatically increasing cleaning speed and consistency.
2Reliability
If comprehensive cleaning is performed on all rail vehicles, then reliability of cleaning results is improved, but time consumption and resource usage increase
Solution Approach 1:
The detection device identifies specific locations and extent of soiling on each rail vehicle. The control device creates a targeted cleaning program that applies cleaning elements only to contaminated areas rather than cleaning the entire vehicle uniformly. This localized cleaning approach ensures reliable removal of soiling while minimizing unnecessary cleaning time and resource consumption on already clean surfaces.
3Adaptability or versatility
If multiple cleaning elements are used to handle different soiling types, then cleaning versatility is improved, but device complexity increases
Solution Approach 1:
The cleaning device is designed with a multi-axis robot that can hold and position different types of cleaning elements (brushes, nozzles, cloths) to handle various soiling types including spray paint and graffiti. The system provides versatility through configurable cleaning elements and adaptive cleaning programs rather than requiring separate dedicated devices for each cleaning task, thereby managing complexity while maintaining adaptability.
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
Enables simple, quick, and reliable automatic cleaning of rail vehicles, ensuring they are operational by effectively removing contamination and documenting cleaning results, thereby preventing damage and ensuring readiness for use.
Implementation Method 1
The at least one detection device preferably comprises at least one light sensor or optical detector
Implementation Method 2
The at least one multi-axis robot holds the at least one associated cleaning element and positions it relative to the rail vehicle in such a way that the detected contamination is removed
Implementation Method 3
