Solution Overview

Problem

Adjusting the working depth of agricultural plough implements is challenging due to varying soil conditions and requires manual parameter consideration, often involving a tedious trial and error process, which can lead to inefficient ploughing and increased fuel consumption.

Innovation Solution

A method and system for automatically adjusting the working depth of plough implements using control data indicative of field conditions, including ground contours and soil characteristics, allowing independent adjustment of depth adjustment apparatuses to optimize ploughing depth based on real-time or pre-collected data.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual adjustment of ploughing depth is used, then the plough can be operated without complex equipment, but the adjustment process is tedious and requires trial and error

Engineering Contradiction:
Improveease of depth adjustmentVSAvoidtime for depth adjustment
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The control unit automatically adjusts the working depth of the plough bodies based on received control data indicating field conditions, eliminating the need for manual trial-and-error adjustment by the operator. The system serves itself by autonomously optimizing ploughing depth according to soil characteristics and ground contours.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical adjustment with an automated control system that uses control data (such as soil characteristics and ground contours) to automatically adjust the working depth. This substitution of mechanical manual operation with an automated control mechanism resolves the contradiction between ease of operation and time consumption.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If uniform deep ploughing is applied across the entire field, then soil preparation is thorough, but fuel consumption increases unnecessarily in areas where less depth is needed

Engineering Contradiction:
Improvequality of soil preparationVSAvoidfuel consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent applies different working depths to different locations within the field based on local soil characteristics and ground contours. The control unit adjusts the working depth of individual plough bodies according to control data specific to each location, ensuring thorough soil preparation where needed while reducing depth in areas where it is not necessary, thus optimizing fuel consumption.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The system dynamically adjusts the working depth of the plough bodies in real-time based on received control data indicating varying field conditions. Rather than maintaining a static uniform depth, the system continuously adapts the ploughing depth to match local soil characteristics and ground contours, resolving the contradiction between reliable soil preparation and energy efficiency.

Inventive Principle:
Principle #15Dynamics

3Productivity

If the working depth is increased to handle hard soil, then ploughing effectiveness improves, but the fuel consumption and mechanical stress increase

Engineering Contradiction:
Improveploughing effectivenessVSAvoidfuel consumption
Core Design Contradiction:
ProductivityVSUse of energy by moving object

Solution Approach 1:

The patent changes the working depth parameter dynamically based on control data indicating soil characteristics. When hard soil is detected, the system increases the working depth to maintain ploughing effectiveness. When soil conditions allow, the system reduces the depth parameter to decrease fuel consumption and mechanical stress, thus resolving the contradiction between productivity and energy use.

Inventive Principle:
Principle #35Parameter changes

4Measurement precision

If individual plough bodies are adjusted independently, then precise depth control is achieved, but the device complexity increases

Engineering Contradiction:
Improveprecision of depth controlVSAvoidcomplexity of adjustment apparatus
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent divides the plough implement into individually controllable segments (plough bodies), each with its own depth adjustment capability. The control unit can adjust the working depth of individual plough bodies independently based on received control data, achieving precise depth control for each location while managing complexity through modular independent adjustment mechanisms.

Inventive Principle:
Principle #1Segmentation
