Solution Overview

Problem

Existing agricultural working devices, such as mulching and mowing devices, lack adjustable components that can adapt to varying conditions like humidity, soil moisture, and plant residue types, leading to inefficiencies and potential damage due to fixed positions and lack of adaptability.

Innovation Solution

The support roller is pivotably mounted and adjustable, allowing it to change positions relative to the working rotor, and the cutting edge can be adjusted mechanically or hydraulically, enabling optimal operation across different conditions, including varying humidity and terrain, while a scraper rail and crop guide plate are designed for efficient material handling and dust reduction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If components are arranged in fixed locations on the device, then the device structure is simple and stable, but the device cannot adapt to varying working conditions such as humidity, soil moisture, and plant residue types

Engineering Contradiction:
Improveadaptability to working conditionsVSAvoiddevice structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The support roller is designed to be pivotably mounted on the housing, allowing it to dynamically adjust its position between a retracted position and a forward position. This dynamic configuration enables the device to adapt to varying working conditions such as different soil moisture levels, humidity, and plant residue types, while maintaining a relatively simple overall structure.

Inventive Principle:
Principle #15Dynamics

2Manufacturing precision

If the support roller is positioned close to the working rotor, then cutting quality is improved, but plant material accumulates in the device area inside the housing

Engineering Contradiction:
Improvecutting qualityVSAvoidplant material accumulation
Core Design Contradiction:
Manufacturing precisionVSObject-generated harmful factors

Solution Approach 1:

The support roller can be pivoted between a retracted position (reducing accumulation risk) and a forward position (improving cutting quality). This dynamic positioning allows operators to optimize performance based on specific working conditions, such as plant moisture content and residue type, while minimizing harmful accumulation effects.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

By changing the position parameter of the support roller relative to the working rotor, the device can optimize cutting quality while controlling plant material accumulation. The adjustable positioning enables parameter optimization based on working conditions such as soil adhesion capacity and plant matter humidity.

Inventive Principle:
Principle #35Parameter changes

3Object-generated harmful factors

If the support roller is positioned far from the working rotor, then plant material accumulation is reduced, but cutting quality and shredding effectiveness deteriorate

Engineering Contradiction:
Improveplant material accumulationVSAvoidcutting quality
Core Design Contradiction:
Object-generated harmful factorsVSManufacturing precision

Solution Approach 1:

The pivotable support roller allows dynamic adjustment between retracted and forward positions, enabling operators to optimize the balance between reducing plant material accumulation and maintaining cutting quality based on specific working conditions such as plant moisture and residue type.

Inventive Principle:
Principle #15Dynamics

4Adaptability or versatility

If movable sub-elements are added to the device housing for adjustment, then adaptability to different working conditions is improved, but device stability is reduced and safety standards are violated

Engineering Contradiction:
Improveadjustability to working conditionsVSAvoiddevice stability
Core Design Contradiction:
Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The pivotable support roller serves multiple functions: it adjusts cutting quality, controls plant material accumulation, and adapts to different working conditions. This multi-functional design provides adaptability while maintaining device stability through a single integrated movable element rather than multiple separate adjustable components.

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