Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Agricultural distribution devices often fail to achieve even distribution of granular materials like seed, fertilizer, or biocide, and they also incur significant energy losses during the distribution process.
Innovation Solution
A distributor unit with a unique design featuring an inlet, multiple outlet channels, and a distributor region with elongated openings that connect to transport channels, allowing for precise distribution by utilizing gravity for material transport, which reduces energy consumption and enhances distribution accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional distribution devices are used, then the structure is simple and easy to manufacture, but the distribution precision is poor with variances of 10-20%
Solution Approach 1:
The distributor is segmented into multiple distributor openings (at least two) arranged in a row along the elongated distributor region. Each opening connects to outlet channels that lead to different transport channels. This segmentation allows the material flow to be divided into multiple outbound flows, achieving even distribution with variances of only 1-2% by distributing material through multiple pathways rather than a single opening.
Solution Approach 2:
The distributor region is designed with an elongated shape where the length is greater than the width, creating a directional flow path. The distributor openings are arranged in a row along this elongated dimension, and the outlet channels extend in a direction substantially perpendicular to the principal direction of material flow. This dimensional arrangement optimizes material distribution by creating a controlled flow path that enhances precision.
2Loss of energy
If conventional distribution devices are used, then the device is simple, but energy losses are significant during material transport
Solution Approach 1:
The outlet channels are designed to extend in a direction substantially perpendicular to the principal direction of material flow in the distributor region. This orthogonal arrangement creates a more efficient flow path that reduces unnecessary material movement and energy loss. The cross-sectional areas of the inlet and distributor region are also matched (equally large +/-10%, +/-5%, or +/-1%) to minimize flow resistance and energy dissipation at transitions.
Solution Approach 2:
The outlet channels serve as intermediary structures that efficiently transfer material from the distributor openings to the transport channels. By providing dedicated outlet channels for each transport channel and arranging them perpendicular to the main flow direction, the system creates an efficient intermediate pathway that reduces energy loss during the transfer process.
3Manufacturing precision
If a single outlet channel is used, then the structure is simple, but uneven distribution in the inlet results in uneven distribution between transport channels
Solution Approach 1:
The system uses multiple outlet channels (at least two) corresponding to the multiple distributor openings. Each outlet channel connects to a specific transport channel, creating multiple independent pathways for material flow. This segmentation ensures that even if the inlet distribution is somewhat uneven, the material is redistributed across multiple outlets, achieving uniform distribution between transport channels with variances of only 1-2%.
Solution Approach 2:
Each outlet channel is specifically designed to receive material from specific distributor openings and deliver it to appropriate transport channels. The local configuration of outlet channels and distributor openings ensures that material is distributed evenly across all transport channels by providing dedicated pathways that compensate for inlet distribution variations.

AI summary
An agricultural implement comprises a distributor unit for distribution of granular material, which distributor unit comprises an inlet, a plurality of outlet channels, which are situated below the inlet and which connect to transport channels (13a, 13b, 14a, 14b) for pneumatic onward transport of the granular material, and a distributor region (1226), which is situated between the inlet and the outlets and which, viewed in a plane transversely to a direction of flow in the distributor region, forms distributor openings (1226a, 1226b, 1226c, 1226d, 1226e, 1226f) leading to respective outlets. The distributor region, viewed in said plane, has a length (L) and a width (B), in which the length is greater than the width. The distributor openings are arranged in a row along one of said length and width. Viewed along said row of distributor openings, at least two, preferably all, pairs of adjacent distributor openings connect to outlet channels which lead to different transport channels.
