Solution Overview

Problem

Existing soil tillage tool carriers require complex structural configurations and significant space to adjust the angle of attack for tillage tools, which is inefficient and costly.

Innovation Solution

A tool carrier with a crossbeam held by a clamping mechanism involving holding arms and a lever arm, allowing for stepless adjustment of the angle of attack through a rotational movement, minimizing component count and space usage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a complex adjusting mechanism with multiple components is used to adjust the angle of attack, then the angle of attack can be adjusted, but the device complexity and space requirement increase

Engineering Contradiction:
Improveangle of attack adjustmentVSAvoidstructural complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines the angle adjustment function and the tool carrier support function into a single cross-member that performs both functions. The cross-member is pivotably connected to the frame to enable angle adjustment while simultaneously supporting the soil cultivation tools, eliminating the need for separate adjustment mechanisms and reducing overall device complexity

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The cross-member is designed as a multi-functional component that serves multiple purposes: it supports the soil cultivation tools, enables angle of attack adjustment through pivotal connection, and provides a mounting structure for the tools. This universal component replaces what would traditionally require multiple separate components

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

2Adaptability or versatility

If a complex adjusting mechanism with multiple components is used to adjust the angle of attack, then the angle of attack can be adjusted, but the space requirement increases

Engineering Contradiction:
Improveangle of attack adjustmentVSAvoidspace occupation
Core Design Contradiction:
Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

By merging the adjustment mechanism into the cross-member's pivotal connection with the frame, the patent eliminates the need for additional space-consuming adjustment components. The adjustment function is integrated into the existing structural element, minimizing the space footprint

Inventive Principle:
Principle #5Merging (Combining)

3Adaptability or versatility

If traditional adjustment mechanisms are used, then the angle of attack can be adjusted, but the number of components and costs increase

Engineering Contradiction:
Improveangle of attack adjustmentVSAvoidnumber of components
Core Design Contradiction:
Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The patent merges multiple functions into fewer components: the cross-member simultaneously provides structural support, enables angle adjustment through pivotal connection, and supports tool mounting. This consolidation reduces the total number of components required and associated costs

Inventive Principle:
Principle #5Merging (Combining)
