Solution Overview

Problem

Existing planter implements face challenges in accommodating varying row spacings and seed hoppers, with existing technologies limiting the flexibility and flexibility in positioning wheels, and existing technologies failing to efficiently support the weight of the wing sections, with the location of the wing wheels restricting row unit placement and requiring physical reconfiguration for different crops.

Innovation Solution

A planter implement design featuring a frame with a wheel support member that supports a wheel and a rotatable toolbar, allowing for adjustable positioning of the toolbar support member, with a toolbar coupled to the wheel support member, and a toolbar support member, and a toolbar support member that can change the angle of the toolbar relative to the wheel support member, enabling flexible row unit placement and wheel positioning.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If the wing wheels are positioned to enable particular spacing between row units, then the row spacing is fixed and stable, but the adaptability to different crops with different row spacings deteriorates

Engineering Contradiction:
Improverow spacingVSAvoidadaptability to different row spacings
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The patent applies the dynamics principle by making the toolbar rotatable relative to the wing section, allowing the row units to be repositioned dynamically. The toolbar can rotate to different angular positions, enabling adjustment of row spacing without physically moving the wing wheels, thus maintaining stability while achieving adaptability.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent segments the planter implement into distinct functional modules: the wing section with fixed wheels, the rotatable toolbar, and the row units. This segmentation allows the toolbar to be independently rotated to different positions, enabling flexible row spacing adjustment while the wing section remains stable with its fixed wheel positions.

Inventive Principle:
Principle #1Segmentation

2Device complexity

If the toolbar is fixed to the wing section, then the structure is simple and stable, but the flexibility in positioning row units deteriorates

Engineering Contradiction:
Improvestructural simplicityVSAvoidflexibility in row unit placement
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The patent introduces a rotatable connection between the toolbar and wing section, transforming the fixed structure into a dynamic one. The toolbar can rotate to different angular positions relative to the wing section, providing flexibility in row unit placement while maintaining relatively simple structural implementation through the use of a rotation mechanism.

Inventive Principle:
Principle #15Dynamics

3Productivity

If the central hopper is made larger to increase planting speed, then the productivity increases, but the weight increases requiring more or larger wheels

Engineering Contradiction:
Improveplanting speedVSAvoidweight of central hopper
Core Design Contradiction:
ProductivityVSWeight of moving object

Solution Approach 1:

The patent distributes the seed storage function across multiple smaller hoppers located at different positions on the planter, rather than using one large central hopper. This dimensional distribution allows the system to maintain high planting productivity while reducing the weight concentration on any single support point, thereby avoiding the need for additional or larger wheels.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

4Stability of the object's composition

If the wing wheels are positioned to support the wing section, then the wing section is stable, but the location limits where row units can be placed

Engineering Contradiction:
Improvewing section stabilityVSAvoidrow unit placement options
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The patent separates the support function (wing wheels on wing section) from the planting function (row units on toolbar). The wing section with its stable wheel positioning remains fixed, while the toolbar with row units can rotate independently to different positions, thus maintaining wing section stability while expanding row unit placement options.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The rotatable connection between the toolbar and wing section enables dynamic repositioning of row units without affecting the stable positioning of the wing wheels. The toolbar can rotate to access different planting positions while the wing section remains stationary and stable, resolving the conflict between stability and placement flexibility.

Inventive Principle:
Principle #15Dynamics
