Solution Overview
Problem
Agricultural implements face challenges in achieving uniform distribution of granular products like seeds or fertilizers across multiple rows due to fixed deposition parameters in ground engaging opener assemblies, leading to uneven distribution and difficulty in implementing sectional control.
Innovation Solution
The implementation of multiple tool meters pneumatically coupled to ground engaging opener assemblies, allowing for on-demand seed distribution and control of seed flow rates, enabling precise management of seed deposition and sectional operation by each tool meter.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If fixed deposition parameters are used in ground engaging opener assemblies, then the system structure remains simple, but uniform distribution of granular products across multiple rows cannot be achieved
Solution Approach 1:
The system divides the granular product distribution control into multiple independent tool meters, each responsible for specific rows. Each tool meter independently meters and distributes product to its assigned opener assemblies, enabling precise control of distribution uniformity across different row sections without requiring complex centralized control.
Solution Approach 2:
Each tool meter is equipped with independent metering capabilities tailored to its specific row assignments. This allows different deposition parameters and rates to be applied locally to different rows, achieving uniform distribution across the entire implement while maintaining simple individual component design.
2Adaptability or versatility
If centralized product distribution is used from a single location, then the system structure remains simple, but sectional control of different row portions cannot be implemented
Solution Approach 1:
The distribution system is segmented into multiple tool meters distributed along the implement, each capable of independent control. This segmentation enables different sections of rows to receive product from different tool meters with different deposition rates,实现 sectional control while keeping each individual tool meter relatively simple.
Solution Approach 2:
Tool meters serve as intermediary devices between the central product source and the ground engaging opener assemblies. Each tool meter receives product from the central location and independently controls its distribution to assigned rows, providing the adaptability for sectional control without requiring direct complex control of each opener assembly.
3Manufacturing precision
If uniform product distribution is attempted across all rows, then the system operates uniformly, but uneven distribution tendencies in specific rows cannot be corrected
Solution Approach 1:
Each tool meter can be independently adjusted to compensate for uneven distribution tendencies in its assigned rows. This local adjustment capability allows operational flexibility to correct specific distribution problems in particular rows while maintaining uniform operation in other rows, achieving both precision and ease of operation.
Solution Approach 2:
The system allows changes in deposition parameters (such as deposition rate, timing, and amount) at each tool meter based on the specific needs of assigned rows. This enables correction of uneven distribution tendencies by adjusting parameters locally without affecting the entire system, maintaining both uniformity and operational flexibility.

AI summary
One embodiment describes an agricultural implement. The agricultural implement includes a plurality of ground engaging opener assemblies that each excavates a trench into soil and deposits a granular product into the trench as the agricultural implement is towed though a field; and a first tool meter coupled to the agricultural implement and pneumatically coupled to a first portion of the plurality of ground engaging opener assemblies. The first tool meter instructs a pneumatic distribution system to supply the granular product to the first tool meter based at least in part on a first amount of granular product stored in the first tool meter; and pneumatically distributes the granular product to the first portion of the plurality of ground engaging opener assemblies.
