Solution Overview

Problem

Existing driver's cabs in rail vehicles face challenges in providing easy access to controls and ensuring comfortable seating for drivers with varying body geometries, leading to impaired views and increased risk of damage to critical control lines.

Innovation Solution

The driver's cab is designed with distinct operating areas for frequently used controls and less frequently used functions, with the display device positioned for optimal visibility and the first control element placed on a side of the seat, allowing the driver to operate essential functions with minimal head movement and maintaining comfort.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the operating element is integrated on the driver's seat to improve accessibility, then the driver can easily reach the control element, but the risk of damage to control lines increases and additional installation effort is required

Engineering Contradiction:
Improveaccessibility of control elementVSAvoidrisk of damage to control lines
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent extracts the first operating element from the driver's seat location and relocates it to a fixed position on the vehicle body or dashboard. This separation eliminates the control line damage risk associated with seat movement while maintaining driver accessibility through optimized positioning and armrest design.

Inventive Principle:
Principle #2Taking out (Extraction)

2Ease of operation

If the driver's seat is adjusted in longitudinal position to improve comfort, then the driver can reach the control element, but the driver's view of the surroundings is impaired

Engineering Contradiction:
Improvecomfort of driverVSAvoidimpaired view of surroundings
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent decouples the operating element from the movable driver's seat by relocating it to a fixed position on the vehicle body. This allows the seat to be positioned for optimal viewing while the control element remains accessible through its fixed placement on the dashboard or panel, eliminating the trade-off between comfort and visibility.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces adjustable armrests that can be positioned dynamically to accommodate different driver preferences and body geometries. This dynamic adjustment allows the driver to maintain an optimal viewing position while still having easy access to the fixed operating element through the adjustable armrest support.

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If controls are distributed over numerous areas to improve functionality, then various functions can be provided, but finding and operating controls becomes difficult

Engineering Contradiction:
Improvevariety of functionsVSAvoidease of finding controls
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent merges frequently used operating elements into a centralized control panel or dashboard area that is within easy reach of the driver. This consolidation improves accessibility and reduces the time to find controls while maintaining all necessary functions. Less frequently used controls can remain in other locations.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent segments controls into different groups based on usage frequency and importance. The first operating element and frequently used controls are placed in easily accessible locations on the dashboard or panel, while less frequently used controls can be distributed elsewhere. This segmentation optimizes both versatility and ease of operation.

Inventive Principle:
Principle #1Segmentation

AI summary

The driver stand comprises a display device for display of information, which is visually observed by a driver (27) of the vehicle during the journey, where the display device has a screen (11). An operating element (6) is provided for controlling a drive system or a brake system of the vehicle, particularly a traction or brake lever. The operating element is located lateral to the location of a driver seat (25) or laterally before the location of the driver seat. An independent claim is included for a method for manufacturing a driver stand of a track-bound vehicle, particularly a rail vehicle.
