Solution Overview

Problem

Current rail vehicle interfaces are inefficient for stationary operations, requiring manual connection and disconnection of power and data cables, which is time-consuming and prone to errors, and lack interoperability across different vehicles and land-based systems.

Innovation Solution

A moveable interface connector that automatically connects and disconnects electrical power and data interfaces between rail vehicles and land-based systems, using a stowing mechanism to transition between stowed and in-use positions, allowing for simultaneous power and data transfer without the need for manual intervention.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual connection and disconnection of power and data cables is used, then the interface can be established between rail vehicles and land-based systems, but the connection process is time-consuming and prone to errors

Engineering Contradiction:
Improveconnection processVSAvoidconnection time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The interface connector automatically performs connection and disconnection operations without requiring manual intervention. The system uses sensors to detect the presence of rail vehicles and automatically activates the stowing mechanism to establish or release connections, making the system serve itself rather than requiring human operation.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The interface connector incorporates a moveable stowing mechanism that dynamically transitions between stowed and deployed positions. This dynamic structure allows the connector to automatically adjust its state based on operational conditions, enabling rapid connection and disconnection while maintaining reliability.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If separate power and data interfaces are used, then each interface can be optimized for its specific function, but the coupling process becomes complex and time-consuming

Engineering Contradiction:
Improveinterface optimizationVSAvoidcoupling process
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The interface connector merges power and data transmission functions into a single integrated connector design. This unified interface allows both power and data connections to be established simultaneously through one coupling action, reducing the complexity of the coupling process while maintaining the functional optimization of separate power and data channels.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The interface connector is designed as a multi-functional device that handles both power and data transmission through a single standardized interface. This universal design enables the same connector to serve multiple purposes (power supply, data communication, diagnostic functions) without requiring separate specialized connectors for each function.

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

3Adaptability or versatility

If land-based interfaces are provided at stationary depots, then power and data can be supplied to stationary trains, but the coupling process is onerous and time-consuming

Engineering Contradiction:
Improveland-based interface capabilityVSAvoidcoupling efficiency
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The land-based interface connector automatically detects approaching trains and initiates the connection process without manual intervention. The system uses sensors to monitor train presence and automatically deploys the connector to establish power and data connections, significantly improving coupling efficiency at stationary depots.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The interface connector is pre-positioned and prepared in advance at land-based interfaces. The stowing mechanism keeps the connector ready for immediate deployment, and the system pre-establishes connection parameters before the train arrives, enabling rapid coupling as soon as the train is in position.

Inventive Principle:
Principle #10Preliminary action

4Ease of operation

If the interface connector is extended for connection, then it can couple to rail vehicles, but it obstructs the track when not in use

Engineering Contradiction:
Improveconnection capabilityVSAvoidtrack obstruction
Core Design Contradiction:
Ease of operationVSArea of stationary object

Solution Approach 1:

The interface connector uses a dynamic stowing mechanism that allows it to transition between extended (connection) and retracted (storage) positions. When not in use, the connector automatically retracts into a compact stowed position that minimizes track obstruction, and only extends when a rail vehicle is detected and connection is required.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The interface connector is designed with a nested structure where the coupling components can be retracted into the housing when not in use. This nesting arrangement allows the connector to occupy minimal space in the stowed position, reducing track obstruction while maintaining full connection capability when deployed.

Inventive Principle:
Principle #7Nested doll (Nesting)
