Solution Overview

Problem

Current solutions for automating seed placement in industrial grow pods do not allow for precise and efficient seeding of seeds into cells of a tray coupled to a cart moving on a track, hindering the continuous operation of the grow pod.

Innovation Solution

A seeder head with a bore and movable hold arms actuated by actuators, controlled by a computing device, which allows for precise placement of seeds into cells without obstructing the cart's movement, using a mechanism that includes a seed dispenser and a vibrating mechanism to handle stuck seeds.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If a machine is used to plant seeds into the ground, then automation is improved, but precision placement of seeds into cells of a tray coupled to a moving cart is hindered

Engineering Contradiction:
Improveautomation of seed plantingVSAvoidprecision placement of seeds into cells
Core Design Contradiction:
Extent of automationVSManufacturing precision

Solution Approach 1:

The seeder head is designed with movable hold arms that can dynamically adjust their position to precisely control seed release timing. The first hold arm moves to release the first seed, followed by the second hold arm releasing the second seed, allowing precise placement into individual cells while maintaining automation. This dynamic positioning resolves the contradiction between automated operation and precision placement.

Inventive Principle:
Principle #15Dynamics

2Productivity

If seed placement speed is increased, then productivity is improved, but cart forward movement is hindered

Engineering Contradiction:
Improveseed placement speedVSAvoidcart forward movement speed
Core Design Contradiction:
ProductivityVSSpeed

Solution Approach 1:

The seeder head operates using periodic action where the first hold arm and second hold arm sequentially release seeds at predetermined intervals. This rhythmic, periodic seed release mechanism allows for high-speed automated seeding without disrupting the continuous forward movement of the cart along the track, resolving the contradiction between seeding speed and cart movement speed.

Inventive Principle:
Principle #19Periodic action

3Manufacturing precision

If hold arms are used to control seed release, then manufacturing precision is improved, but device complexity increases

Engineering Contradiction:
Improveprecision of seed placementVSAvoidcomplexity of seeder mechanism
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The seed release mechanism is segmented into two independent hold arms (first hold arm and second hold arm), each controlled by its own actuator. This segmentation allows each component to perform a simple, well-defined function of holding and releasing seeds at specific times, achieving high precision placement while keeping individual component complexity low. The modular segmented design resolves the contradiction between precision and overall device complexity.

Inventive Principle:
Principle #1Segmentation
