Solution Overview

Problem

Existing devices for moving heavy rolling loads on railway rails are cumbersome, require installation at only one end, necessitate long power cables, and lack the ability to easily stop the load at a specific position.

Innovation Solution

A compact, autonomous movement device with a gear motor, drive roller, support rollers, and a pivotally mounted braking pad, allowing for easy positioning and stopping, featuring a carriage with retractable wheels for mobility and a rechargeable battery for power.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a drive device is installed at one end of the rolling load, then the device can be simplified in structure, but it cannot be installed between the axles and requires very long power supply cables

Engineering Contradiction:
Improvedevice structureVSAvoidinstallation location flexibility
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The drive device is divided into separate functional modules: a drive unit with motor and drive roller, and a braking unit with braking pad. These modules can be independently positioned on the rolling load, allowing the drive unit to be placed between axles for compactness while the braking unit is positioned separately for effective braking. This segmentation resolves the contradiction by enabling flexible installation locations without requiring very long power cables.

Inventive Principle:
Principle #1Segmentation

2Device complexity

If a drive device is installed at one end of the rolling load, then the device can be simpler, but it requires very long power supply cables

Engineering Contradiction:
Improvedevice structureVSAvoidpower supply cable length
Core Design Contradiction:
Device complexityVSLength of stationary object

Solution Approach 1:

By segmenting the device into separate drive and braking modules that can be independently positioned, the power cable length is reduced. The braking unit is positioned close to the drive unit, allowing the power cable to connect them directly without extending across the entire rolling load, thus reducing cable length while maintaining structural simplicity.

Inventive Principle:
Principle #1Segmentation

3Device complexity

If a drive device is installed at one end of the rolling load, then the device can be simpler, but the rolling load cannot stop at a given position

Engineering Contradiction:
Improvedevice structureVSAvoidposition control
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The device is segmented into independent drive and braking modules. The braking unit, positioned separately from the drive unit, can apply brakes to the rolling load at any desired position. This separation allows the braking function to operate independently of the drive location, enabling precise position control while maintaining overall device simplicity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The braking pad acts as an intermediary element between the rolling load and the braking force. It can be positioned at any location on the rolling load and provides the braking action, enabling the load to stop at given positions without complicating the overall device structure.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Productivity

If existing drive devices are used, then they can move the rolling load, but they are cumbersome and require excessive weight

Engineering Contradiction:
Improveload moving capabilityVSAvoiddevice weight
Core Design Contradiction:
ProductivityVSWeight of moving object

Solution Approach 1:

The device is divided into separate drive and braking modules, each with minimal necessary components. This segmentation allows for a lighter overall structure by eliminating redundant elements and enabling optimized placement of heavy components (motor and braking mechanism) close to each other, reducing the weight that needs to be supported by the rolling load.

Inventive Principle:
Principle #1Segmentation

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 efficient, one-operator operation with the ability to easily stop the load at a desired position, reducing weight and complexity while maintaining stability and control.

Implementation Method 1

frictional contact is established between the drive cylinder and the rolling cylinders, which causes the carriage to move upon rotation of the drive cylinder and, at the same time, the rolling load to move by rotation of its wheel driven by rotation of the drive cylinder

Implementation Method 2

two support rollers arranged to come to bear on the rail of the railway receiving said wheel of the load to be moved and configured to be driven in rotation by adhesion by said drive roller
