Solution Overview

Problem

Current seeding systems either singulate seeds for precise placement or meter them volumetrically, but not both efficiently, limiting flexibility in seed dispersal methods, especially with the increasing use of hybrid seeds that require accurate and cost-effective planting techniques.

Innovation Solution

A seed metering system that allows for interchangeable seed disks, enabling either singulating or volumetric metering modes by swapping between singulating and volumetric metering disks, each with distinct mechanisms such as seed openings or buckets/paddles, to adapt to different seed types and planting needs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a seeding system uses singulating meters for precise seed placement, then seed placement precision is improved, but system versatility deteriorates because it cannot perform volumetric metering

Engineering Contradiction:
Improveseed placement precisionVSAvoidmetering mode versatility
Core Design Contradiction:
Measurement precisionVSAdaptability or versatility

Solution Approach 1:

The seed disk is designed with a central mounting point that accepts both singulating disks and volumetric metering disks, allowing the same housing to perform multiple metering functions. The disk can be removed and replaced to switch between singulating mode (for precise placement) and volumetric mode (for high-rate seeding), making the system universal and adaptable to different seeding requirements

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

2Productivity

If a seeding system uses volumetric meters for high-rate seeding, then seeding speed is improved, but seed placement precision deteriorates

Engineering Contradiction:
Improveseeding speedVSAvoidseed placement precision
Core Design Contradiction:
ProductivityVSMeasurement precision

Solution Approach 1:

The system dynamically switches between metering modes by replacing the seed disk. When high seeding speed is required, a volumetric metering disk with buckets or paddles is installed to handle high-rate seeding. When precision placement is needed, a singulating disk with individual seed openings is installed. This dynamic reconfiguration allows the system to optimize for either speed or precision based on operational requirements

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If separate systems are used for singulating and volumetric metering, then functional specialization is improved, but device complexity deteriorates

Engineering Contradiction:
Improvemetering function specializationVSAvoidsystem configuration complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent merges both singulating and volumetric metering capabilities into a single seed disk housing. The housing contains a central mounting point that accommodates different types of disks (singulating disks with seed openings, or volumetric disks with buckets/paddles). This consolidation eliminates the need for separate dedicated systems, reducing overall device complexity while maintaining functional specialization through disk interchangeability

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A seed disk mountable within a housing of a singulating meter includes a first side, a second side opposite the first side, a central mounting point defining a center of rotation for the seed disk, and a volumetric metering element extending from the first side of the seed disk, the volumetric metering element configured to entrain a plurality of seeds.
