Solution Overview

Problem

Conventional seed planting systems randomly deposit seeds without regard for orientation, which can affect seed germination and plant growth, leading to suboptimal crop health and productivity.

Innovation Solution

A seed delivery assembly that includes belts and rollers to orient seeds with the pedicel down and flats to the side, ensuring consistent placement in the planting furrow, using synchronized motor control to maintain seed orientation during delivery.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If seeds are deposited randomly without orientation control, then the planting process is simple and fast, but seed germination and plant growth are suboptimal

Engineering Contradiction:
Improveseed germination rateVSAvoidseed delivery system complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system orients seeds to the desired position (pedicel down, flats to the side) before deposition into the furrow. The seed delivery assembly pre-positions seeds in the correct orientation during the delivery process, ensuring optimal germination conditions are established before planting occurs.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent replaces random mechanical dropping with a controlled belt-based transport system. The first belt with inner portion provides controlled movement and orientation maintenance, substituting the simple random drop mechanism with a more complex but controllable belt transport mechanism that ensures proper seed orientation.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Manufacturing precision

If a belt system with powered and non-powered rollers is used to orient seeds, then seed orientation precision is improved, but the device complexity increases

Engineering Contradiction:
Improveseed orientation precisionVSAvoidbelt and roller system complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The seed delivery assembly is divided into functional segments: a first belt with an inner portion for seed engagement, powered rollers for driving the belt, and non-powered rollers for tension and guidance. This segmentation allows each component to perform its specific function in maintaining seed orientation while simplifying the overall design through modular functional divisions.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The first belt acts as an intermediary between the seed meter and the furrow. It receives oriented seeds from the meter, maintains their orientation through controlled transport on the inner portion, and delivers them to the furrow. The powered and non-powered rollers serve as intermediaries to control belt movement and tension without directly contacting the seeds.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

Techniques and/or systems are disclosed for depositing a seed in planting trough in a desired orientation. A system can be devised that receives a seed (350) from a seed meter (216), and deposits in the ground in the prepared orientation as received from the meter (216). A seed delivery assembly (300) comprises one or more belts (302, 302'), each with an inner portion that operably moves downward. The inner portion receives and engages with an oriented seed (350) delivered in a target orientation at the top portion (312) and translates the oriented seed (350) to the bottom portion (314), where it is ejected in the target orientation. A one or more powered rollers (304, 304') can be engaged with the one or more belts (302, 302') to provide rotational power for the translation. Further, one or more non-powered rollers (306, 306') or guides can be engaged with the one or more belts (302, 302') to provide tension to the one or more belts (302, 302') during translation.
