Seed Injection Shaft for Precise Depth and Close Row Planting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing seed planting technologies face challenges in achieving consistent seed depth and orientation, which can lead to inconsistent emergence and resource use, and the need for closer row placement without creating continuous seed trenches.
Innovation Solution
A seed injection system that penetrates the soil to deposit seeds without a continuous trench, allowing for controlled seed orientation and depth, using a shaft actuated by an actuator to place seeds and potentially deliver fluids or solids, with mechanisms to control seed spacing and emergence timing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a planter with opener discs creates a continuous seed trench, then seeds can be deposited into the trench, but it is difficult to achieve consistent seed depth and orientation
Solution Approach 1:
The patent removes the opener disc mechanism entirely and replaces it with a seed injection system that directly penetrates the soil to deposit seeds at the desired depth without creating a continuous trench. This extraction of the problematic component eliminates the source of inconsistent seed depth and orientation while simplifying the overall device structure.
Solution Approach 2:
The patent replaces the mechanical opener disc system with a controlled seed injection mechanism that uses a tube to deliver seeds directly to the target depth. This substitution transforms the approach from mechanical trench creation to precise seed placement, achieving consistent depth control without the complexity of opener discs.
2Area of stationary object
If row units use opener discs to create seed trenches, then seeds can be planted, but rows cannot be placed closer together
Solution Approach 1:
By removing the opener disc that creates wide trenches, the patent enables closer row spacing. The seed injection system penetrates the soil minimally, allowing adjacent rows to be placed closer together without the soil disturbance and space requirements associated with traditional opener disc mechanisms.
Solution Approach 2:
The patent applies local quality by creating minimal, localized soil penetration only where seeds are deposited, rather than creating continuous wide trenches. This localized approach reduces overall soil disturbance and allows for tighter row spacing while still achieving effective seed placement.
3Reliability
If seeds are planted with traditional planters, then seeds can be deposited, but emergence is inconsistent and resource use is inefficient
Solution Approach 1:
The patent replaces the traditional planter mechanism with a seed injection system that precisely controls seed placement depth and orientation. This substitution ensures consistent emergence by delivering seeds at uniform depths with proper orientation, eliminating the variability inherent in traditional trench-based planting methods.
Solution Approach 2:
The patent changes the critical parameters of seed placement by controlling depth and orientation through the injection tube mechanism. By precisely adjusting and maintaining these parameters, the system achieves consistent emergence and improves resource utilization efficiency compared to traditional planting methods.

AI summary
A seed unit for placing seeds into soil includes a seed meter for singulating seeds, a shaft to deliver the seeds into soil during operation, and an actuator coupled to the shaft. The actuator moves the shaft during operation and the shaft delivers seeds into the soil without a continuous seed trench.
