Solution Overview
Problem
Existing snow removers for track junctions lack efficiency in operating based on actual snow conditions, leading to unnecessary operations and ineffective snow removal.
Innovation Solution
A snow remover system that includes an ejector, an information obtainer, and a controller to adjust ejection pressure, frequency, and time based on snow accumulation and snowfall data, with a determination unit to assess interference and adjust operation modes accordingly, and a heating device for combined fluid ejection and heating control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the ejection device operates continuously or based on simple snowfall detection, then snow removal coverage is ensured, but operational efficiency decreases and unnecessary operations increase
Solution Approach 1:
The system uses a determination unit that continuously monitors track junction conditions (snow accumulation, switching operations, rail temperature) and provides feedback to the controller. The controller adjusts ejection device operation based on this feedback, activating ejection only when snow actually interferes with track junction movement, thereby eliminating unnecessary operations and reducing energy consumption while maintaining effective snow removal
Solution Approach 2:
The ejection device operates in multiple dynamic modes (first operation mode with higher ejection pressure for heavy snow, second operation mode with lower ejection pressure for light snow) that are selectively activated based on real-time snow conditions. This dynamic operation adapts the system to actual needs, improving efficiency while reducing energy waste compared to continuous or fixed-mode operation
2Productivity
If the ejection device operates at high ejection pressure continuously, then snow removal effectiveness is improved, but energy consumption increases
Solution Approach 1:
The system applies high ejection pressure (first operation mode) only when snow accumulation significantly interferes with track junction switching operations. When snow interference is minimal, the system switches to low ejection pressure (second operation mode). This partial application of high-power action based on actual need maintains snow removal effectiveness while dramatically reducing overall energy consumption compared to continuous high-pressure operation
3Device complexity
If the ejection device operates without precise snow condition detection, then system complexity is reduced, but snow removal precision decreases
Solution Approach 1:
The detection system is segmented into multiple independent sensors each monitoring specific parameters: snow accumulation amount, snowfall detection, rail temperature, and switching operation status. The controller integrates information from these separate detection channels to precisely determine when and how to operate the ejection device, achieving high measurement precision while keeping individual sensor components simple and manageable
