Solution Overview

Problem

Conventional control devices for rail vehicles are complex, expensive, and require extensive electrical routing, making them costly to maintain and inefficiently used in fully automatic systems where emergency control desks are rarely needed.

Innovation Solution

A detachable, portable control unit with a multi-pole electrical contact point connects to the rail vehicle's electrical systems, featuring a mechanical interface for easy assembly and a locking mechanism to prevent unauthorized removal, and a foldable design for protection and space efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a conventional driver's compartment or simplified driver's desk is provided in fully automatic rail vehicles, then emergency control functionality is available, but component costs and installation costs are extremely high due to the large number of electrical components and lines required

Engineering Contradiction:
Improveemergency control functionalityVSAvoidcomponent and installation complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The control device is divided into a portable operating unit that can be detached and stored. This segmentation allows the control functionality to be available when needed while reducing the permanent installation complexity and component count in the vehicle.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The control functionality is extracted from the permanent vehicle structure and placed in a portable operating unit that can be removed and stored. This extraction eliminates the need for permanent electrical routing and components while maintaining emergency control capability.

Inventive Principle:
Principle #2Taking out (Extraction)

2Adaptability or versatility

If four driver's desks are provided in coupled train formations, then control functionality is available at all ends, but maintenance costs increase due to rare usage of consoles at coupled train ends

Engineering Contradiction:
Improvecontrol availability at all endsVSAvoidmaintenance costs
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The portable operating unit serves multiple functions and can be used at any end of the train formation. A single unit can be moved between different positions, replacing the need for multiple permanent control desks while maintaining adaptability.

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

Solution Approach 2:

The control device transitions from a static, permanent installation to a dynamic, movable unit that can be positioned as needed. This dynamic approach allows the same unit to serve multiple locations, reducing the total number of control devices required.

Inventive Principle:
Principle #15Dynamics

3Device complexity

If a portable operating unit with detachable contact point is used, then assembly is simplified and costs are reduced, but the contact point may be damaged or soiled when not in use

Engineering Contradiction:
Improveassembly complexityVSAvoiddamage or soiling of contacts
Core Design Contradiction:
Device complexityVSObject-affected harmful factors

Solution Approach 1:

A protective cover is provided for the detachable contact point when not in use. This cover protects the electrical contacts from damage and soiling while allowing easy access when the operating unit is connected to the vehicle.

Inventive Principle:
Principle #30Flexible shells and thin films
