Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

In agricultural product meters, the rotation of row units from a working to a non-working position causes agricultural products to flow out of the meter, leading to reduced efficiency and interference with the operation of powered conveyors during planting operations.

Innovation Solution

A product control assembly with first and second barriers that pivotally couple to block the flow of agricultural products from the storage area to the outlet when in the non-working position, while allowing excess products to flow back into storage when in the working position, preventing product loss and conveyor interference.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If row units are rotated from working position to non-working position, then the implement can be transported or positioned for headland operations, but agricultural product flows out of the meter causing loss and interfering with conveyor operation

Engineering Contradiction:

Improverow unit position adaptabilityVSAvoidagricultural product loss

Core Design Contradiction:

Adaptability or versatilityVSLoss of substance

Solution Approach 1:

The flow control barrier is positioned in advance to block the product path before the row unit reaches the non-working position, preventing agricultural product from flowing out during rotation and transport operations

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

A flow control barrier is introduced as an intermediary element between the agricultural product storage area and the outlet, selectively controlling product flow based on row unit position while preventing both product loss and conveyor interference

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If row units are rotated to non-working position, then transport and headland operations are enabled, but powered agricultural product conveyor operation is interfered with due to product accumulation

Engineering Contradiction:

Improverow unit position adaptabilityVSAvoidconveyor operation reliability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

Inventive Principle:

Principle #24Intermediary (Mediator)

3Loss of substance

If product flow is completely blocked during non-working position, then product loss is prevented, but excess product cannot return to storage area when returning to working position

Engineering Contradiction:

Improveagricultural product loss preventionVSAvoidplanting efficiency

Core Design Contradiction:

Loss of substanceVSProductivity

Solution Approach 1:

The flow control barrier is designed to dynamically change position based on row unit orientation, automatically transitioning from a blocking configuration during non-working positions to a non-blocking configuration during working positions, enabling both product loss prevention and efficient planting operations

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The flow control barrier operates in periodic cycles corresponding to row unit position changes, blocking flow during non-working positions and allowing flow during working positions, synchronizing with the operational rhythm of the planting implement

Inventive Principle:

Principle #19Periodic action

AI summary

A product control assembly for an agricultural product meter includes a first product control barrier configured to extend along a product path. The product path extends from an agricultural product storage area to an outlet, the first product control barrier includes a first portion and a second portion, the second portion is pivotally coupled to the first portion, the second portion is configured to contact an outlet barrier while the agricultural product meter is in a non-working position. The product control assembly also includes a second product control barrier configured to form an end of the agricultural product storage area and to be spaced apart from the outlet barrier, and the first and second product control barriers are configured to cooperate to substantially block flow of the agricultural product from the agricultural product storage area into the outlet while the agricultural product meter is in the non-working position.
