Solution Overview

Problem

Existing operator station systems fail to provide an efficient and stable configuration for operator stations, particularly in operating machines, particularly self-propelled machines, allowing for operator stations, which allows for operator stations, which allows for operator stations to be positioned in a defined manner with extensive mobility.

Innovation Solution

An operator station system comprising a suspension support arrangement fixed to the machine frame, allowing the operator station to be displaced in a first direction and rotated about an axis, with a movement system that includes a displacement rail arrangement and a displacement slide, and a suspension element for vertical support, reducing shock introduction through elastic coupling elements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the operator station is supported standing on the machine frame, then the operator station is stable, but shocks are significantly introduced into the operator station

Engineering Contradiction:

Improvestability of operator stationVSAvoidshocks introduced into operator station

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The operator station is inverted from a standing support configuration to a suspended support configuration. Instead of the operator station standing on the machine frame, it is suspended from the machine frame by the movement system, which reverses the support direction and eliminates direct shock transmission while maintaining stability through the suspension mechanism.

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The movement system acts as an intermediary between the machine frame and the operator station. This intermediate suspension mechanism absorbs and dampens shocks before they reach the operator station, while still providing stable support and enabling the desired positioning and rotation capabilities.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Object-affected harmful factors

If the operator station is suspended from the machine frame, then shocks are reduced, but the operator station may be less stable under gravity

Engineering Contradiction:

Improveshocks introduced into operator stationVSAvoidstability of operator station

Core Design Contradiction:

Object-affected harmful factorsVSReliability

Solution Approach 1:

The movement system provides dynamic stabilization through its suspension mechanism. The system allows controlled movement in the first displacement direction and rotation about the axis of rotation while maintaining stable positioning through the interaction of gravitational force and the suspension support arrangement, adapting to operational requirements.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The suspension mechanism changes the physical parameters of support from rigid standing contact to elastic suspension. This parameter change allows the system to filter shock frequencies while maintaining positional stability through the combined effects of gravity and suspension geometry.

Inventive Principle:

Principle #35Parameter changes

3Device complexity

If the operator station is fixed to the machine frame, then the configuration is simple, but the operator station lacks mobility and positioning flexibility

Engineering Contradiction:

Improvesimplicity of operator station configurationVSAvoidmobility and positioning flexibility of operator station

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The support system is segmented into distinct functional components: the suspension support arrangement attached to the machine frame, the movement system providing displacement and rotation, and the operator station. This segmentation enables independent optimization of each component for both simplicity and mobility.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The movement system performs multiple functions: it suspends the operator station, enables displacement in the first direction, allows rotation about the axis of rotation, and provides shock absorption. This multi-functionality achieves mobility and positioning flexibility without proportionally increasing system complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A control station system for an operating machine, in particular a self-propelled ground processing machine, includes a suspension support arrangement which is to be fixed to a machine frame of an operating machine, and a control station which is mounted on the suspension support arrangement such that it can be displaced in a first displacement direction by a movement system and can rotate about an axis of rotation. The control station is suspended from the suspension support arrangement in an upper region of the control station in a vertical direction by the movement system.
