Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Round bales have a tendency to roll uncontrollably after ejection, posing a safety risk due to their weight, especially on hilly terrain.

Innovation Solution

Agricultural balers are equipped with a protrusion inserter and controller to insert a roll-reducing protrusion on the bale surface, which is then wrapped with wrapping material to inhibit rolling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If round bales are ejected from the baling chamber, then the baling operation is completed and productivity is maintained, but the bales roll uncontrollably causing safety risks

Engineering Contradiction:

Improvebaling operation efficiencyVSAvoiduncontrollable rolling of bales

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The protrusion is inserted into the bale surface before ejection, creating a rolling-inhibiting feature in advance. The controller activates the protrusion inserter to embed the protrusion into the bale surface while the bale is still in or near the baling chamber, ensuring the anti-rolling feature is already in place before the bale is discharged onto the ground

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The protrusion acts as an intermediary element between the bale and the ground surface. It protrudes from the bale surface and contacts the ground first during rolling, creating a mechanical stop that prevents the bale from rolling uncontrollably while maintaining the natural ejection process

Inventive Principle:

Principle #24Intermediary (Mediator)

2Object-affected harmful factors

If a protrusion is inserted into the bale surface to prevent rolling, then safety is improved, but the device complexity increases

Engineering Contradiction:

Improverolling hazard reductionVSAvoidwrapping assembly structure

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The protrusion inserter utilizes the existing wrapping mechanism's operational cycle and bale positioning system to perform the protrusion insertion automatically. The controller integrates the protrusion insertion operation with the existing wrapping sequence, eliminating the need for separate manual intervention or complex additional positioning mechanisms

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The protrusion inserter is integrated into the existing wrapping assembly, allowing the same mechanical structure to serve both wrapping and protrusion insertion functions. The controller manages both operations through a unified control system, reducing overall device complexity while achieving multiple objectives

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A wrapping assembly for an agricultural baler includes: a supply of wrapping material; a wrapping mechanism configured to wrap the wrapping material around a formed round bale; a protrusion inserter configured to insert a roll-reducing protrusion on a surface of the formed round bale; and a controller operably coupled to the wrapping mechanism and the protrusion inserter. The controller is configured to: output a wrap initiation signal to the wrapping mechanism so the wrapping mechanism begins wrapping the formed round bale; and output a protrusion insertion signal to the protrusion inserter so the roll-reducing protrusion is inserted on a surface of the formed round bale and is subsequently wrapped by wrapping material wrapped around the formed round bale by the wrapping mechanism.
