Solution Overview

Problem

Existing rotary tillers are limited in their ability to adjust the width of the soil section worked and cannot perform ridging operations, requiring separate machines for these tasks.

Innovation Solution

A multifunction rotary tiller with a vertically rotating tool unit and adjustable axis allows for varying furrow widths and direction, enabling both furrowing and ridging capabilities.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the rotary tiller uses a fixed tool unit configuration, then the structure is simple, but the width of the soil section worked cannot be adjusted

Engineering Contradiction:
Improveadjustability of soil section widthVSAvoidstructure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The tool unit is made dynamically adjustable through a vertical rod that can rotate around a vertical axis, allowing the operator to change the working width by rotating the tool unit to different angular positions. This dynamic adjustment mechanism enables the same structure to adapt to different soil section widths without requiring multiple fixed configurations.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If the rotary tiller uses a fixed tool unit orientation, then the structure is simple, but ridging operations cannot be performed

Engineering Contradiction:
Improveoperational versatility (furrowing and ridging)VSAvoidstructure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The tool unit is designed with multi-functionality by enabling it to perform both furrowing and ridging operations through rotation around the vertical axis. The same tool unit, when oriented at different angles, can create furrows or move earth for ridging, eliminating the need for separate specialized machines and achieving operational versatility without proportionally increasing structural complexity.

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

3Adaptability or versatility

If the tool unit cannot be rotated around a vertical axis, then the structure is simple, but the direction of earth movement cannot be changed

Engineering Contradiction:
Improvedirection control of earth movementVSAvoidstructure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The vertical rod enabling rotation around a vertical axis provides dynamic directional control. By rotating the tool unit to different angular positions around this vertical axis, the operator can change the direction in which earth is moved, allowing flexible adaptation to different operational requirements such as furrowing versus ridging without complicating the overall structure.

Inventive Principle:
Principle #15Dynamics
