Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing agricultural seed treatment systems fail to effectively capture and manage unapplied treatment fluid that contacts the interior walls of the seed treatment chamber, leading to potential contamination of downstream equipment and inefficiencies.

Innovation Solution

A treatment discharge catcher is positioned at the terminal end of the seed treatment chamber, comprising a sloped member and a liquid collector, which directs unapplied treatment fluid away from the central flow path and into a collection system, utilizing gravity and adhesion forces to guide the excess fluid into a liquid collector for disposal or reuse.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If unapplied treatment fluid flows out of the seed treatment chamber outlet, then the treatment process continues, but downstream equipment becomes contaminated and treatment efficiency decreases

Engineering Contradiction:

Improvetreatment efficiencyVSAvoidequipment contamination

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent extracts the unapplied treatment fluid from the main flow path by introducing a separate collection system. The extraction occurs through a collection container positioned to receive fluid exiting the chamber, separating the harmful unapplied fluid from the treated seed flow and preventing downstream contamination while maintaining treatment productivity

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces an intermediary component (collection container and associated structure) between the treatment chamber outlet and the downstream equipment. This intermediary captures and holds the unapplied treatment fluid, acting as a barrier that prevents direct contact between the contaminating fluid and downstream equipment

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If treatment fluid is applied to seeds, then seed treatment is achieved, but unapplied fluid accumulates and requires management

Engineering Contradiction:

Improveseed treatment qualityVSAvoidtreatment fluid waste

Core Design Contradiction:

ReliabilityVSLoss of substance

Solution Approach 1:

The patent implements a system to discard unapplied treatment fluid in a controlled manner while recovering it from mixing with downstream materials. The collection container captures wasted fluid, preventing it from contaminating downstream equipment or mixing with treated seeds, thereby managing the loss of substance while preserving treatment quality

Inventive Principle:

Principle #34Discarding and recovering

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The solution effectively separates unapplied treatment fluid from treated seeds, maintaining equipment cleanliness and operational integrity by preventing contamination and allowing for the collection and potential reuse of excess treatment fluid.

Implementation Method 1

The unapplied treatment in contact with the chamber wall moves away from the vertical flow path of the particulate material along the drip flow path towards the treatment discharge catcher. A top surface of the unapplied treatment contacts an underside surface of the sloped member and moves towards the liquid collector, which may be due to forces of gravity and adhesion.

Methodology Applied

Scientific EffectGravity: Gravitation

Implementation Method 2

Methodology Applied

Scientific EffectAdhesion: Adhesive

Implementation Method 3

Unapplied treatment is separated from the particulate material using the treatment discharge catcher. The treatment fluid is propelled horizontally into contact with the particulate material within the vertical flow generated inside the treatment chamber. The particulate material coated with the treatment fluid flows through a central flow path. An unapplied quantity of the treatment fluid contacts an interior side of the chamber wall.

AI summary

A treatment discharge catcher may be positioned at a terminal end of a treatment chamber. The treatment discharge catcher has a sloped member and a liquid collector. The sloped member extends downwardly and outwardly from a liquid dispenser. The liquid dispenser coats a particulate material with a treatment. Unapplied treatment may coat an interior of the treatment chamber. The sloped member directs unapplied treatment towards the liquid collector. The liquid collector has an interior wall that extends upwardly towards the sloped member to form a slotted gap. The particulate material may be prevented passage through the slotted gap. The unapplied treatment flows along an underside of the sloped member through the slotted gap. The unapplied treatment releases at a release portion of the sloped member. A port May discharge unapplied treatment collected inside the liquid collector.
