Solution Overview

Problem

Conventional bin sweep systems using augers often clog with particulate material, posing safety risks and operational challenges, as they are prone to jamming and require hazardous clearing processes.

Innovation Solution

A modular storage bin sweep system utilizing a series of interconnected paddles on an endless loop, powered by a motor unit and driven by a surface-engaging wheel system, allowing for safe and reliable movement of particulate matter across the bin floor to a central sump, with features like traction enhancement and pivotability for adaptability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If conventional augers with helical flighting are used to move particulate matter, then the sweep system can effectively clear material across the bin floor, but the augers become clogged or jammed with agglomerations of particulate material

Engineering Contradiction:
Improveparticulate matter clearance efficiencyVSAvoidauger clogging resistance
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The continuous helical flighting of conventional augers is segmented into discrete, spaced-apart flight elements. These segmented flights prevent agglomerations of particulate material from bridging across the auger, eliminating clogging while maintaining the scraping and moving function across the bin floor

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Instead of using a continuous solid helical surface that traps material, the invention inverts the approach by using open, spaced flight elements that allow material to pass through. This inversion transforms the auger from a material-trapping structure to a material-moving structure that prevents accumulation

Inventive Principle:
Principle #13The other way round (Inversion)

2Productivity

If conventional augers are used in the sweep system, then the system can move particulate matter to the sump, but clearing clogging matter from the flighting becomes dangerous to life and limb

Engineering Contradiction:
Improveparticulate matter transport capabilityVSAvoidsafety hazard during maintenance
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The segmented flight design creates discrete, easily removable elements rather than a continuous welded helical structure. This segmentation allows maintenance personnel to safely clear clogs by simply removing and cleaning individual flight segments without exposing themselves to dangerous rotating machinery

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The modular flight element design enables operators to perform maintenance themselves without requiring specialized tools or dangerous disassembly procedures. The flights can be quickly removed, cleaned of accumulated material, and reinstalled, making the system self-maintainable by regular operators

Inventive Principle:
Principle #25Self-service

3Adaptability or versatility

If a modular sweep system with multiple units is used, then the system becomes highly adaptable to different bin configurations, but the device complexity increases

Engineering Contradiction:
Improvebin configuration adaptabilityVSAvoidnumber of interconnected components
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The sweep system is divided into modular, interchangeable flight elements and support structures that can be configured in different patterns and lengths. This segmentation allows the same basic components to adapt to various bin sizes and shapes without requiring custom-designed systems for each configuration

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The modular components are designed with universal connection interfaces and standardized dimensions, allowing the same flight elements and support structures to serve multiple bin configurations. This universality reduces overall system complexity by using a common component library across different applications

Inventive Principle:
Principle #6Universality (Multi-functionality)
