Solution Overview

Problem

The existing driver's cab designs for rail vehicles face challenges in easily attaching front window sun blinds and route monitoring cameras without obstructing the windscreen wipers' field of view and requiring complex installation positions.

Innovation Solution

A longitudinal member is attached to the connecting beam, serving as a single component for both the route observation camera's fastening device and the lower holding devices for the front window sun blinds, reducing installation space, weight, and connection points, with a transverse hole for adjustable camera positioning and optional cross member for upper sun blind holding.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If separate mounting devices are used for the route observation camera and front window sun blinds on the vehicle body shell, then each component can be independently positioned, but the number of connection points increases and assembly complexity increases

Engineering Contradiction:
Improveease of installationVSAvoidnumber of connection points
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent combines the mounting functions for the route observation camera and front window sun blinds into a single longitudinal member attached to the connecting beam. This merging of mounting functions reduces the number of separate connection points to the vehicle body shell while simplifying the installation process, as the longitudinal member serves as an integrated carrier for both components.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The longitudinal member attached to the connecting beam serves multiple functions: it acts as a support structure for the route observation camera, provides mounting points for the front window sun blinds, and integrates these functions into a single component. This multi-functionality reduces the overall complexity of the mounting system.

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

2Ease of operation

If multiple separate mounting devices are used for camera and sun blinds, then positioning flexibility is maintained, but the weight of the mounting system increases

Engineering Contradiction:
Improvepositioning flexibilityVSAvoidweight of mounting system
Core Design Contradiction:
Ease of operationVSWeight of stationary object

Solution Approach 1:

By merging the mounting functions into a single longitudinal member, the patent reduces the total weight of the mounting system compared to using multiple separate mounting devices. The integrated structure eliminates redundant materials while maintaining positioning flexibility through the transverse hole for camera adjustment and mounting points for sun blinds.

Inventive Principle:
Principle #5Merging (Combining)

3Adaptability or versatility

If separate mounting structures are used for camera and sun blinds, then each component can be independently adjusted, but the installation space required increases

Engineering Contradiction:
Improveindependent adjustabilityVSAvoidinstallation space
Core Design Contradiction:
Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The patent utilizes the vertical dimension by attaching the longitudinal member to the connecting beam, which is positioned in the upper area of the driver's cab. This vertical positioning allows the route observation camera and front window sun blinds to be mounted in the available space without requiring additional horizontal installation area, while the transverse hole in the longitudinal member provides adjustment capability along the longitudinal axis.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

4Reliability

If multiple connection points on the vehicle body are used, then secure mounting is achieved, but the assembly effort increases

Engineering Contradiction:
Improvemounting securityVSAvoidassembly effort
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent reduces assembly effort by merging multiple mounting functions into a single longitudinal member that attaches to the connecting beam at one location. This approach maintains mounting security through the robust connection to the connecting beam while significantly reducing the number of separate assembly operations required compared to using multiple independent mounting devices on the vehicle body shell.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

The invention relates to an operator compartment (1) of a rail vehicle, comprising two front windows (13, 14) which are separated by a connection beam (15), a track monitoring camera (19) which is attached in the lower region of the connection beam (15) by means of a securing device (20), and a front window roll-up sun shield (25, 26) which can be drawn in the interior of the operator compartment (1) and which has guides (23, 24) running along both sides of the front windows (13, 14), said guides comprising lower retaining devices (21, 22). The aim of the invention is to allow a comparably simple attachment of the front window roll-up sun shield and the track monitoring camera in such an operator compartment. This is achieved in that a longitudinal support (18) is attached to the connection beam (15) in the lower region of the connection beam, said longitudinal support retaining the securing device (20) of the track monitoring camera (19) and having guides (23, 24) and the lower retaining devices (21, 22) for the front window roll-up sun shield (25, 26) opposite one another. The invention also relates to an assembly device for a track camera and a front window roll-up sun shield of a rail vehicle.
