Solution Overview

Problem

Existing agricultural soil tillage machines require complex and numerous adjustment elements for height adjustment and folding to comply with transport width regulations, limiting flexibility in adapting to uneven surfaces and complicating the process of meeting legal transport width requirements.

Innovation Solution

The design features a soil tillage machine with a packer section's roller frame oriented transversely to the forward direction, rotatably mounted on the frame construction with a stop element to limit rotation, allowing for simplified depth adjustment and flexible ground adaptation, and includes a frame construction with adjustable sections that can be stored or rearranged to meet transport width constraints.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the packer section is attached to the frame construction in a height-adjustable manner using hydraulically operated cylinders, then the depth adjustment capability is improved, but the device complexity increases due to numerous adjustment elements and complex control devices

Engineering Contradiction:
Improvedepth adjustment capabilityVSAvoidcomplexity of adjustment elements
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The packer section is divided into multiple independently adjustable packer units, each capable of individual depth adjustment. This segmentation allows localized adaptation to uneven surfaces without requiring complex centralized height adjustment mechanisms, thereby reducing overall device complexity while maintaining depth adjustment capability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The packer section incorporates dynamically adjustable components that can adapt their position and orientation during operation. The roller frame is designed to allow rotational movement and height adjustment through simpler mechanical means rather than complex hydraulic systems, enabling flexible ground adaptation with reduced complexity.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If folding stops are designed to limit movement after pivoting of machine segments, then compliance with legally required transport width is achieved, but the device complexity increases due to correspondingly complex folding stops

Engineering Contradiction:
Improvecompliance with transport widthVSAvoidcomplexity of folding stops
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The folding mechanism incorporates pre-positioned stops and mechanical limiters that automatically prevent excessive pivoting of machine segments. These built-in mechanical constraints ensure compliance with transport width requirements without requiring complex active control systems or sophisticated folding stop mechanisms, thereby reducing device complexity while maintaining regulatory compliance.

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

3Adaptability or versatility

If the roller frame is rotatably mounted on the frame construction with a stop element to limit rotation, then the flexibility in adapting to uneven surfaces is improved, but the device complexity increases due to additional mounting mechanisms

Engineering Contradiction:
Improveflexibility in ground adaptationVSAvoidcomplexity of mounting mechanisms
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The roller frame is rotatably mounted on the frame construction, allowing it to dynamically adapt its orientation to uneven ground surfaces. This rotational freedom is limited by simple stop elements that prevent excessive rotation, providing flexible ground adaptation through straightforward mechanical means rather than complex active control systems, thereby maintaining adaptability while minimizing mounting mechanism complexity.

Inventive Principle:
Principle #15Dynamics
