Solution Overview

Problem

Current twin row planters face challenges in synchronizing seed distribution across narrow row distances, leading to yield loss, incomplete harvesting, and increased machine costs due to separate seed distributor bodies and complex motion mechanisms, which result in trampling of plants and inefficient harvesting processes.

Innovation Solution

A twin row seed distributor body with a single seed hopper and motion mechanism, featuring a shaft bearing and motion transmission shafts that enable synchronized seeding on both sides, allowing for adjustable spacing and easy disc mounting, eliminating the need for separate seed distributor bodies and reducing machine weight and horsepower requirements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If separate seed distributor bodies are used for twin row sowing, then sowing on two rows is enabled, but machine weight and complexity increase

Engineering Contradiction:

Improvetwin row sowing capabilityVSAvoidnumber of seed distributor bodies

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines two separate seed distributor bodies into a single integrated twin-row seed distributor body that can sow seeds on two rows simultaneously. This merging reduces the number of separate components, simplifies the overall structure, and decreases machine weight while maintaining the capability to sow on two rows at the same time

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The single twin-row seed distributor body is designed to perform multiple functions: it can sow seeds on two different rows simultaneously, adjust spacing between rows, and accommodate different seeding rates. This multi-functional design eliminates the need for separate seed distributor bodies for each row

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Ease of operation

If separate motion mechanisms are used for each seed distributor body, then independent control is achieved, but synchronization errors and system complexity increase

Engineering Contradiction:

Improveindependent control of seed distributorsVSAvoidsynchronization of seeding

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent merges two separate motion mechanisms into a single motion mechanism that controls both seeding operations simultaneously. This unified mechanism ensures synchronized seed distribution on both rows by using a common drive system, eliminating synchronization errors that occur with separate mechanisms while maintaining independent control through adjustable components

Inventive Principle:

Principle #5Merging (Combining)

3Object-affected harmful factors

If row distance is increased to prevent plant trampling, then plant damage is reduced, but seed population per unit area decreases

Engineering Contradiction:

Improveplant trampling during cultivationVSAvoidseed population per unit area

Core Design Contradiction:

Object-affected harmful factorsVSProductivity

Solution Approach 1:

The patent implements adjustable row spacing in the twin-row seed distributor body, allowing the distance between rows to be dynamically changed based on crop requirements and cultivation conditions. This dynamic adjustment enables optimal balance between preventing plant trampling during cultivation and maintaining high seed population density per unit area

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes the parameter of row spacing from fixed to variable, enabling the system to adapt to different agricultural needs. By allowing parameter adjustment, the system can optimize for either plant protection or maximum seed population depending on the specific cultivation scenario

Inventive Principle:

Principle #35Parameter changes

4Ease of operation

If twin sowing is performed with 20 cm or greater row distance, then harvesting and cultivation are facilitated, but yield per unit area is reduced

Engineering Contradiction:

Improveharvesting and cultivation accessibilityVSAvoidyield per unit area

Core Design Contradiction:

Ease of operationVSProductivity

Solution Approach 1:

The patent enables dynamic adjustment of row spacing in the twin-row seed distributor, allowing operators to optimize the balance between accessibility for harvesting and cultivation operations and maximization of yield per unit area. The adjustable spacing mechanism permits narrowing row distances when high yield is prioritized while still maintaining operational feasibility

Inventive Principle:

Principle #15Dynamics
