Solution Overview

Problem

Agricultural ploughs face challenges in adapting to varying soil types, moisture conditions, and tractor speeds due to the inability to dynamically adjust the shape of the mould board, which affects ploughing efficiency and fuel consumption.

Innovation Solution

An agricultural machine system with an adjustable support strut equipped with a powered actuating mechanism, allowing the distance between attachment points to be dynamically adjusted based on real-time conditions, thereby modifying the mould board's shape to optimize performance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the mould board shape is fixed, then the structure is simple and cost-effective, but the plough cannot adapt to different soil types and working conditions

Engineering Contradiction:
ImproveAdaptability to different soil types and working conditionsVSAvoidComplexity of the support strut system
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The support strut is designed with adjustable length capability, transforming it from a static component to a dynamic one. The powered actuating mechanism enables the strut length to be varied during operation, allowing the mould board shape to be modified in real-time according to soil conditions and working parameters, thus resolving the contradiction between structural simplicity and adaptability.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The invention changes the physical parameter of the support strut (its length) to modify the mould board's shape. By adjusting the strut length via the powered actuating mechanism, the curvature and angle of the mould board are altered, enabling adaptation to different soil types and working conditions while maintaining a relatively simple overall structure.

Inventive Principle:
Principle #35Parameter changes

2Productivity

If the mould board shape is adjusted for different conditions, then ploughing efficiency improves, but additional space and cost are required for adjustment mechanisms

Engineering Contradiction:
ImprovePloughing efficiencyVSAvoidAdditional space and cost for adjustment mechanisms
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The support strut serves multiple functions: it provides structural reinforcement to the mould board, acts as a lever to modify the mould board shape, and serves as a mounting point for the powered actuating mechanism. This multi-functionality reduces the need for separate adjustment mechanisms, thereby minimizing additional space and cost while improving ploughing efficiency.

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

Solution Approach 2:

The powered actuating mechanism is integrated within or alongside the support strut structure. The actuator is positioned such that it utilizes the existing strut space, and the strut itself becomes part of the adjustment system rather than requiring separate dedicated components. This nesting approach minimizes additional space requirements while enabling shape adjustment for improved productivity.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Adaptability or versatility

If the support strut length is fixed, then the assembly is simple and reliable, but the mould board cannot be optimized for varying tractor speeds and moisture conditions

Engineering Contradiction:
ImproveOptimization for varying tractor speeds and moisture conditionsVSAvoidFuel consumption
Core Design Contradiction:
Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The support strut length is made dynamically adjustable through the powered actuating mechanism, allowing the mould board shape to be optimized for current working conditions such as tractor speed and soil moisture. This dynamic adaptation reduces ploughing resistance and drag, thereby lowering fuel consumption compared to a fixed strut design that cannot be optimized for varying conditions.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system incorporates sensors that detect working conditions (soil moisture, ploughing depth, tractor speed) and provide feedback to the control device. Based on this feedback, the powered actuating mechanism automatically adjusts the support strut length to optimize the mould board shape, minimizing drag and fuel consumption for the current operating conditions.

Inventive Principle:
Principle #23Feedback

4Loss of energy

If the mould board shape is modified by adjusting the support strut, then drag and fuel consumption are reduced, but the attachment points and actuating mechanism add structural complexity

Engineering Contradiction:
ImproveFuel consumption and dragVSAvoidAttachment points and actuating mechanism structure
Core Design Contradiction:
Loss of energyVSDevice complexity

Solution Approach 1:

The attachment points serve dual purposes: they secure the support strut to the mould board and plough structure for structural support, and they serve as pivot points for the powered actuating mechanism to modify the mould board shape. This multi-functionality reduces the need for separate components, thereby minimizing structural complexity while achieving reduced drag and fuel consumption through shape optimization.

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