Solution Overview

Problem

Existing railway vehicle control units are not optimally positioned during certain maneuvers, limiting ergonomics and modularity, and do not provide sufficient flexibility for driver visibility and space utilization.

Innovation Solution

A control unit with a first and second support arm system that allows for multi-axis rotation, enabling the control unit to be moved between various positions within the cabin based on driver operations, improving visibility and flexibility in height and depth positioning, and freeing up floor space.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the control unit is fixed and secured to the floor of the cabin, then the structure is simple and stable, but the ergonomics and adaptability for different maneuvers are limited

Engineering Contradiction:
Improveadaptability of control unit positionVSAvoidcomplexity of control unit structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The control unit is transformed from a fixed structure to a dynamic one through the introduction of support arms with multiple rotation axes. The control unit can now rotate and reposition itself relative to the cabin floor, adapting to different driving maneuvers while maintaining structural integrity through controlled mechanical joints.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The control unit structure is segmented into multiple rotatable components connected by support arms. Instead of a single fixed unit, the system divides the control unit into separable elements that can independently rotate around different axes, enabling flexible positioning without requiring a completely complex redesign.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If the control unit position is fixed, then the device complexity is low, but the driver's visibility and ergonomics during certain maneuvers are not optimal

Engineering Contradiction:
Improveergonomics of control unitVSAvoidcomplexity of support structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The support structure incorporates multiple rotation axes that allow the control unit to dynamically adjust its position and orientation. This enables the driver to access optimal ergonomic positions during different maneuvers, with the structure adapting in real-time rather than requiring multiple fixed control units.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The multi-axis support structure serves multiple functions: it provides ergonomic adjustment, improves driver visibility, and enables the control unit to adapt to various driving scenarios. A single universal support system replaces what would otherwise require multiple specialized fixed installations.

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

3Adaptability or versatility

If the control unit is fixed to the floor, then the installation is simple, but the cabin floor space is occupied and flexibility in positioning is limited

Engineering Contradiction:
Improveflexibility in positioningVSAvoidcomplexity of mounting system
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The mounting system transitions from a static floor attachment to a dynamic multi-axis rotation mechanism. This allows the control unit to move freely within certain parameters while maintaining secure attachment, providing positioning flexibility without requiring complete removal and reinstallation for different configurations.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The support arms introduce additional rotational dimensions to the mounting system. Instead of simple planar attachment to the floor, the control unit gains freedom to rotate around multiple axes, adding spatial dimensions to the positioning capability while keeping the base mounting point fixed on the floor.

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