Solution Overview

Problem

Soil cultivation machines lack operational variability, particularly in adjusting load and compensating for ground level differences, which limits their effectiveness in different soil conditions.

Innovation Solution

The soil cultivation machine features a height-adjustable chassis arrangement with independently adjustable chassis units and a vibration mechanism with unbalanced masses to optimize load distribution and soil interaction, allowing for varied operational settings.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the chassis arrangement is fixed in height, then the machine structure is simple, but the operational variability and ability to compensate for ground level differences is limited

Engineering Contradiction:
Improveoperational variabilityVSAvoidchassis arrangement complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The chassis arrangement is made height-adjustable through hydraulic cylinders, allowing the machine to adapt to different ground levels and operational requirements. The chassis can be raised or lowered relative to the machine frame, transforming from a static to a dynamic structure that responds to terrain variations.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The chassis arrangement is divided into multiple independently adjustable chassis units, each capable of individual height adjustment. This segmentation allows different parts of the machine to adapt to local ground conditions independently, enhancing overall operational variability without requiring complete system redesign.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If the chassis units are independently height-adjustable, then the ability to compensate for ground level differences is improved, but the device complexity increases

Engineering Contradiction:
Improveground level compensation capabilityVSAvoidchassis unit adjustment mechanism
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Each chassis unit is equipped with individual height adjustment capability through hydraulic cylinders, enabling real-time adaptation to ground level differences. The independent adjustment mechanisms allow the chassis to dynamically respond to uneven terrain, maintaining machine stability across varying elevations.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The height adjustment system operates autonomously through hydraulic actuators that can independently position each chassis unit based on terrain requirements, reducing the need for manual intervention and simplifying operation despite the complex underlying mechanism.

Inventive Principle:
Principle #25Self-service

3Productivity

If the soil tillage roller is always in contact with the soil, then the soil cultivation function is continuous, but the machine cannot be easily moved to different work areas

Engineering Contradiction:
Improvesoil cultivation continuityVSAvoidmachine mobility
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The soil tillage roller's contact with the ground is made variable through the height-adjustable chassis arrangement. The roller can be dynamically positioned between contact and non-contact states, allowing the machine to switch between cultivation mode (roller on ground) and transport mode (roller elevated), thereby achieving both continuous cultivation and easy mobility.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The machine alternates between operational phases where the roller contacts the soil for cultivation and transport phases where it is elevated, creating a periodic cycle of contact and separation that enables both continuous productivity and operational flexibility.

Inventive Principle:
Principle #19Periodic action
