Locomotive Visibility Control System with Sensor-Triggered Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional windshield cleaning systems for locomotives are inefficient and cannot be manually activated for unattended vehicles, leading to reduced visibility due to moisture and fog, which affects both operators and monitoring devices.
Innovation Solution
A visibility control system that includes a sensing module with moisture and photo sensors to detect conditions on the windshield, coupled with a cleaning system comprising a wiper assembly, defogger, and washer fluid system, controlled by a controller that activates these components automatically or via user input to maintain clear visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual activation of cleaning devices is used, then the system is simple to operate, but it cannot be activated for unattended locomotives and is not efficient
Solution Approach 1:
The cleaning system automatically activates itself based on sensor detection of moisture, fog, or opacity conditions on the windshield, eliminating the need for manual operator intervention. The system serves itself by monitoring its own operational needs through integrated sensors and triggering cleaning operations autonomously.
Solution Approach 2:
The system incorporates sensors that continuously monitor the windshield conditions (moisture presence, fog density, opacity) and provide feedback to the controller. Based on this feedback, the controller automatically activates the cleaning system when degradation is detected, creating a closed-loop control system that responds to actual conditions.
2Device complexity
If conventional cleaning devices are used, then the device complexity is low, but visibility is reduced due to moisture and fog affecting operators and monitoring devices
Solution Approach 1:
The cleaning system is designed to serve multiple functions: it cleans the windshield for both the operator's visibility and the monitoring devices' visibility. The system integrates multiple cleaning mechanisms (wipers, defoggers, washers) that can address different types of contamination (moisture, fog, dust) to maintain visibility for all critical observation points.
Solution Approach 2:
The controller acts as an intermediary between the sensors and the cleaning devices, processing sensor data about moisture, fog, and opacity conditions, then coordinating the appropriate cleaning response. This intermediary component enables the system to respond intelligently to different contamination scenarios.
3Use of energy by moving object
If cleaning systems are activated after a certain time interval, then energy consumption is reduced, but visibility is not maintained in real-time when moisture or fog is present
Solution Approach 1:
The sensors continuously monitor for the presence of moisture, fog, or opacity degradation before they severely impact visibility. The system takes preliminary action by activating cleaning operations as soon as contamination is detected, preventing visibility degradation rather than waiting for scheduled intervals.
Solution Approach 2:
The system uses real-time feedback from moisture sensors, fog detectors, and opacity sensors to determine when cleaning is needed. This feedback-driven approach activates the cleaning system only when actually required, avoiding unnecessary energy consumption while maintaining visibility reliability.
