Convertible Two-Rank Planter Layout for Single-Row Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing two-rank agricultural implements face inefficiencies when one rank is not needed for planting, leading to unnecessary pulling, removal, or elevation, resulting in wasted resources and labor.
Innovation Solution
A convertible multiple rank agricultural implement with adjustable drawbars and a separable second rank that can be offset and aligned with the first rank, allowing conversion to a single rank configuration, optimizing spacing and resource utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If both ranks are kept in place but only one rank is used for planting, then the implement provides dual row spacing options, but the unused rank is pulled along unnecessarily causing waste of fuel and resources
Solution Approach 1:
The second rank is divided into two separate sections that can be independently positioned. This segmentation allows one section to remain coupled to the first rank while the other section can be decoupled and positioned away, enabling the implement to operate as a single-rank tool when needed, thus avoiding the energy waste of pulling an entire unused rank.
Solution Approach 2:
The implement transitions from a static two-rank configuration to a dynamic configuration where the second rank sections can be moved between coupled and decoupled states. This dynamic reconfiguration allows the operator to adapt the implement to single-rank or dual-rank operation based on planting requirements, optimizing resource utilization.
2Loss of energy
If the unused rank is removed completely from the implement, then fuel and resource waste is eliminated, but time and labor are lost during removal and reinstallation
Solution Approach 1:
Instead of removing the entire second rank, only the necessary portion (one section) remains coupled while the other section is decoupled and positioned away. This segmentation allows the implement to maintain a compact, single-rank configuration without requiring complete removal of components, thus saving time and labor.
Solution Approach 2:
The second rank sections are designed with quick-couple mechanisms that allow for rapid attachment and detachment. This preliminary design of easily configurable connections enables operators to switch between single and dual rank modes quickly without significant time or labor investment.
3Adaptability or versatility
If the unused rank is raised and locked in an elevated position, then the implement maintains both ranks available, but additional mechanisms and complexity are required
Solution Approach 1:
The second rank is segmented into two sections with independent coupling capabilities. This eliminates the need for complex elevation and locking mechanisms required by traditional two-rank designs, as each section can be independently positioned and secured in a simplified manner.
Solution Approach 2:
The implement uses dynamic coupling mechanisms that allow sections to be easily attached and detached rather than requiring static elevation and locking systems. This dynamic approach reduces mechanical complexity while maintaining operational flexibility.
4Adaptability or versatility
If a two-rank tool is used for single-rank planting, then dual row spacing capability is available, but overall efficiency is reduced due to unnecessary components
Solution Approach 1:
By segmenting the second rank into separate sections with independent coupling, the implement can be configured to operate with only the necessary components engaged. This reduces drag and improves planting efficiency when single-rank operation is needed, while preserving dual row spacing capability when both sections are coupled.

AI summary
A convertible multiple rank agricultural implement for being towed by an agricultural vehicle. The convertible multiple rank agricultural implement includes a towing assembly, a first rank coupled to the towing assembly, wherein the first rank includes a first plurality of row units longitudinally spaced along a longitudinally extending support structure. A second rank is coupled to the first rank, wherein the second rank includes a first section connected to a second plurality of row units, and a second section connected to a third plurality of row units. In a first configuration, the first section and second section are coupled together with a coupler located at adjacent ends of the first section and second section when the second rank is offset and spaced from the first rank. In a second configuration, the first section and second section are spaced apart and longitudinally aligned with the longitudinally extending support structure of the first rank.
