Solution Overview

Problem

Existing operator station systems for self-propelled soil cultivation machines lack comprehensive mobility and stability, particularly on uneven terrain, and fail to provide optimal positioning for observing the work area while minimizing shock transmission.

Innovation Solution

An operator control system with a suspension beam arrangement that allows the operator platform to be displaced and rotated, featuring a motion system with displacement and rotary drives, supported by damping suspension components and guided by a guidance system to maintain stability and reduce shock transmission.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the operator platform is rigidly supported on the machine frame, then the platform remains stable under gravitational influence, but shock transmission to the operator increases and mobility is reduced

Engineering Contradiction:
Improvestability of operator platformVSAvoidshock transmission to operator
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent applies damping suspension components (shock absorbers, springs) in the motion system to cushion shocks before they reach the operator platform. These components are positioned to absorb impact forces during machine operation, particularly when the machine encounters uneven terrain or operational shocks, thereby protecting the operator while maintaining platform stability.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

2Object-affected harmful factors

If the operator platform is suspended from the machine frame, then shock transmission is reduced, but stability under gravitational influence deteriorates

Engineering Contradiction:
Improveshock transmission to operatorVSAvoidstability of operator platform
Core Design Contradiction:
Object-affected harmful factorsVSReliability

Solution Approach 1:

The patent employs a motion system with multiple degrees of freedom including displacement in lateral direction, rotation about vertical axis, and telescopic suspension movement. This dynamic configuration allows the operator platform to adapt its position and orientation in real-time, maintaining stability while isolated from shocks through the telescopic suspension units that can extend and retract to compensate for terrain variations.

Inventive Principle:
Principle #15Dynamics

3Device complexity

If the operator platform is fixed to the machine frame, then the structure is simple and stable, but comprehensive mobility and positioning capability are lost

Engineering Contradiction:
Improvestructural simplicityVSAvoidmobility and positioning of operator station
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The patent divides the operator station system into separable functional components: the operator platform, the motion system with multiple independent actuators, and the suspension beam arrangement. This segmentation allows each component to perform its specific function (displacement, rotation, suspension) independently, providing comprehensive mobility while maintaining manageable structural complexity through modular design.

Inventive Principle:
Principle #1Segmentation

4Adaptability or versatility

If the operator platform is made movable with multiple degrees of freedom, then positioning flexibility improves, but structural complexity and stability under gravity increase

Engineering Contradiction:
Improvepositioning flexibility of operator platformVSAvoidcomplexity of motion system
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The motion system is designed with multi-functional components that perform multiple operations. For example, the telescopic suspension units simultaneously provide shock absorption, positional adjustment, and gravitational compensation. The displacement carriage and suspension beams work together to enable both lateral movement and rotational positioning, reducing the need for separate dedicated mechanisms for each function.

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