Solution Overview

Problem

Current multi-tasking tractors are not well-suited for modern agriculture due to their inflexibility, high cost, and inability to operate effectively in confined or fragile spaces, and they often require complex reconfiguration and emit noise and emissions that are detrimental in sensitive environments.

Innovation Solution

A multi-tasking tractor design featuring a peripheral frame with a central work zone free of traction and transmission components, allowing for flexible tool placement and operation, powered by electric motors for quiet and precise movement, and equipped with interchangeable tools and autonomous control options.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If traditional multi-purpose tractors are equipped with multiple working zones and dedicated implements, then productivity is improved, but the machine becomes complex and expensive to build and reconfigure

Engineering Contradiction:

Improvemulti-task capabilityVSAvoidconfiguration complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The tractor is designed with a universal peripheral frame structure that can accommodate various tools in multiple working zones (front, rear, and central). The standardized mounting points and open central area allow the same base machine to perform diverse agricultural tasks by simply changing tools, rather than requiring complex dedicated configurations for each task type.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The tractor is divided into distinct functional zones (front working zone, rear working zone, and central working zone) with standardized mounting interfaces. This segmentation allows independent selection and attachment of appropriate tools for each zone based on task requirements, simplifying the overall system while maintaining multi-functionality.

Inventive Principle:

Principle #1Segmentation

2Power

If traditional tractors use internal combustion engines, then power is sufficient for heavy tasks, but noise and emissions are harmful in sensitive environments

Engineering Contradiction:

Improvetractive powerVSAvoidnoise and emissions

Core Design Contradiction:

PowerVSObject-affected harmful factors

Solution Approach 1:

The internal combustion engine is replaced with an electric motor system. The electric motor provides sufficient power for agricultural tasks while eliminating noise and emissions, making the tractor suitable for use in sensitive environments such as greenhouses, green zones, and areas near residential areas.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Productivity

If traditional tractors have central mechanical components, then transmission is efficient, but the central work zone is obstructed and inaccessible

Engineering Contradiction:

Improvework zone accessibilityVSAvoidtransmission efficiency

Core Design Contradiction:

ProductivityVSLoss of energy

Solution Approach 1:

The central mechanical transmission components are extracted and relocated to the periphery of the tractor frame. This creates an open, unobstructed central working zone that is fully accessible for tool placement and operator access, while the peripheral location of drive components maintains efficient power transmission to the wheels.

Inventive Principle:

Principle #2Taking out (Extraction)

4Reliability

If traditional tractors are designed for specific tasks, then performance is optimized, but adaptability to different tasks is limited

Engineering Contradiction:

Improvetask-specific performanceVSAvoidtask flexibility

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The tractor employs a universal peripheral frame design with standardized mounting points in front, rear, and central zones. This allows the same base machine to be reliably configured for different tasks by attaching appropriate tools to the suitable zones, maintaining task-specific performance while achieving high adaptability.

Inventive Principle:

Principle #6Universality (Multi-functionality)
