Solution Overview

Problem

Existing methods for clearing snow from track-bound vehicle areas, such as railway tracks, are inefficient and often result in snow accumulation on adjacent tracks and switches, making it difficult to achieve effective and time-efficient snow removal.

Innovation Solution

A device comprising a snow collection aggregate with rotating brushes and feeder screws, coupled with a snow melting unit and a liquid container, allows for wide snow clearance and volume reduction, utilizing side brushes to sweep snow into a conduit for melting and subsequent storage in the container, enabling efficient snow removal and transport.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If traditional ploughing is used to clear snow from tracks, then snow can be removed from the track, but snow accumulates on adjacent tracks and switches

Engineering Contradiction:
Improvesnow removal effectivenessVSAvoidsnow accumulation on adjacent tracks
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The invention extracts the snow removal function from traditional ploughing and relocates it to a centralized collection system. The side brushes extract snow from adjacent tracks and feed it into a collection hopper, preventing snow from being deposited on neighboring tracks while maintaining effective clearance of the primary track.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The invention introduces an intermediary collection system between the ploughing action and the final snow disposal. The side brushes and collection hopper act as intermediaries that capture and redirect snow, preventing direct deposition on adjacent tracks while enabling controlled removal from the track area.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If wide snow clearance is achieved using collection devices, then more snow can be removed efficiently, but device complexity increases

Engineering Contradiction:
Improvesnow clearance width and efficiencyVSAvoidcollection device structure
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The invention segments the snow collection function into modular components: side brushes for snow engagement, feed screws for snow transport, and a collection hopper for accumulation. This segmentation allows each component to perform its specific function efficiently while maintaining overall system manageability and reducing complexity through functional decomposition.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The collection device is designed with multi-functionality, where the side brushes serve both as snow collection tools and as feed mechanisms, the feed screws transport snow while compacting it for volume reduction, and the hopper serves as both collection and temporary storage. This multi-functionality reduces the need for separate dedicated components, thereby reducing overall device complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Quantity of substance

If collected snow is transported without volume reduction, then transport capacity is maintained, but energy consumption and freezing risks increase

Engineering Contradiction:
Improvesnow transport volumeVSAvoidenergy consumption and freezing risk
Core Design Contradiction:
Quantity of substanceVSUse of energy by moving object

Solution Approach 1:

The invention changes the physical parameters of the collected snow by applying mechanical compression through feed screws and the hopper structure. This compression reduces the volume of snow, increasing its density, which in turn reduces the space required for transport and minimizes exposure to cold temperatures, thereby lowering energy consumption and freezing risks during transport.

Inventive Principle:
Principle #35Parameter changes
