Solution Overview

Problem

Existing seed drills face challenges in simplifying the lateral positioning of rotary tools, requiring complex assembly processes and time-consuming adjustments, which affect the accuracy and efficiency of seed placement.

Innovation Solution

A seeder design with rotary tools arranged in two rows on separate beams, each with independent ground-following capabilities and a compact mounting structure, utilizing a console with identical arms to simplify tool positioning and allow for independent mounting, reducing assembly time and enhancing precision.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If rotary tools are mounted individually on crossbeams with complex support structures, then the positioning flexibility is improved, but the assembly time and device complexity increase significantly

Engineering Contradiction:
Improvelateral positioning accuracyVSAvoidassembly time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The patent combines multiple rotary tools (opening discs and seeding discs) onto a single console structure, where tools that were previously mounted separately on different crossbeams are now integrated. This merging reduces the number of individual mounting operations and simplifies the overall assembly process while maintaining precise lateral positioning through the unified console design.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The console is pre-configured with all necessary mounting points and positioning features before field assembly. The lateral positioning of rotary tools is predetermined by the console's fixed geometry, eliminating the need for time-consuming individual adjustments during assembly. This preliminary preparation of the mounting structure significantly reduces setup time.

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If rotary tools are mounted on complex parallelogram suspension structures, then the ground contour following capability is improved, but the device complexity and manufacturing cost increase

Engineering Contradiction:
Improveground contour followingVSAvoidmounting structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the ground contour following function from the lateral positioning function. The console handles precise lateral positioning with fixed geometry, while separate ground-following mechanisms (such as individual tool depth control or frame suspension) handle terrain adaptation. This segmentation allows each subsystem to be optimized independently, reducing overall complexity.

Inventive Principle:
Principle #1Segmentation

3Reliability

If rotary tools are arranged in two rows on separate beams, then the clogging risk is reduced, but the lateral positioning accuracy and assembly precision are compromised

Engineering Contradiction:
Improveclogging resistanceVSAvoidlateral positioning accuracy
Core Design Contradiction:
ReliabilityVSManufacturing precision

Solution Approach 1:

The patent merges the two-row arrangement advantage with precise lateral positioning by mounting both rows of rotary tools on a single rigid console. The console's fixed geometry ensures accurate lateral spacing between tools in both rows, while the two-row configuration itself maintains clogging resistance by distributing tools across different lateral positions. This integration preserves both reliability and precision.

Inventive Principle:
Principle #5Merging (Combining)
