Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional grain bins face issues with flour, dust, and debris accumulating in airflow passageways below the floor, leading to blocked airflow and frequent cleaning needs, especially in larger bins with non-elevated floors.

Innovation Solution

An aerated floor system with perforated planks and filters positioned below the planks to catch debris while allowing airflow, reducing the accumulation of flour, dust, and debris in airflow passageways.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If an elevated floor with perforated planks is used to enable airflow through grain, then grain aeration and conditioning are improved, but flour, dust, and debris accumulate in the space below the floor blocking airflow passageways

Engineering Contradiction:

Improveairflow efficiencyVSAvoiddebris accumulation

Core Design Contradiction:

ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The floor system is segmented into multiple functional layers: perforated planks for grain aeration, a filter layer to capture debris, and an airflow passageway structure. This segmentation allows each layer to perform its specific function - the planks enable grain conditioning while the filter prevents debris from blocking the airflow passageways below.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

A filter layer is introduced as an intermediary element between the perforated planks and the airflow passageway. This filter acts as a mediator that allows air to pass through while intercepting and capturing flour, dust, and debris particles, preventing them from accumulating in the airflow passageways and blocking ventilation.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If sweeps are used to move grain toward the sump, then grain unloading is improved, but flour and debris are pushed through floor perforations accumulating below

Engineering Contradiction:

Improvegrain unloading efficiencyVSAvoiddebris buildup

Core Design Contradiction:

ProductivityVSObject-generated harmful factors

Solution Approach 1:

The filter layer, initially introduced to prevent debris accumulation, inadvertently serves as a collection mechanism for flour and fine debris generated by sweep operations. Instead of allowing these materials to block airflow passageways, the filter captures them, and the accumulated material can be periodically removed through access ports, converting a harmful accumulation problem into a manageable maintenance task.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

3Reliability

If the space below the floor is used for airflow passageways, then grain aeration is improved, but the passageways become blocked by accumulated flour and debris requiring frequent cleaning

Engineering Contradiction:

Improveairflow continuityVSAvoidcleaning frequency

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The filter layer is installed in advance as a preventive measure to intercept debris before it can enter and block the airflow passageways. This preliminary protective action prevents the harmful accumulation that would otherwise require frequent cleaning interruptions, maintaining continuous airflow operation.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The filter layer is designed to be removable and replaceable. When the filter becomes loaded with captured flour and debris, it can be easily removed through access ports and replaced with a clean filter, allowing rapid restoration of airflow efficiency without extensive cleaning operations.

Inventive Principle:

Principle #34Discarding and recovering
