Galvanized Steel Wall Sections for Grain Storage Ventilation

Solution Overview

Problem

Existing temporary storage systems for agricultural products face inefficiencies due to complex and costly perforated panels, susceptibility to clogging, and lack of rigidity to support grain loads, which hinder effective ventilation and structural integrity.

Innovation Solution

The use of free-standing galvanized steel wall sections with a 'J' cross-sectional shape, supported by a triangular configuration and interconnected with louvered panels, providing a strong and ventilated structure that optimizes air flow and reduces the need for additional structural supports.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If perforated panels are used for wall sections, then ventilation is enabled, but the panels are susceptible to clogging and lack rigidity to support grain loads

Engineering Contradiction:

Improveventilation effectivenessVSAvoidpanel rigidity

Core Design Contradiction:

ReliabilityVSStrength

Solution Approach 1:

The wall section is divided into multiple functional layers: a rigid support structure (top chord, bottom chord, vertical members) and a separate ventilation component (perforated metal louvered panels). This segmentation allows each component to optimize its specific function without compromising the other.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The wall section combines different materials with complementary properties: structural members made of rigid material (steel or wood) provide strength and support, while perforated metal louvered panels provide ventilation. This composite construction resolves the contradiction by assigning different materials to different functional requirements.

Inventive Principle:

Principle #40Composite materials

AI summary

Disclosed herein are apparatus and systems for forming a temporary storage facility for granular materials such as agricultural products including grain and corn. The temporary storage facility includes a retaining wall constructed by connecting free-standing wall sections in a circular or rectangular shape. The free-standing wall sections have overlapping elements on the face to hold the agricultural products inside the retaining wall sections while admitting air for ventilation. Ventilation holes are made in the panel elements so as to admit air but prevent water or vermin entry to protect the agricultural products.
