Solution Overview

Problem

Agricultural round balers face challenges in safely and efficiently handling large and heavy rolls of binding material, particularly film rolls, due to the complexity and weight of existing support mechanisms, which can lead to manual handling issues and accidents.

Innovation Solution

A support structure for agricultural round balers that includes a first support element for one end of the spare roll in storage, allowing it to be lifted and rotated into a loading position, while the second end is lifted away from a second support element, enabling axial movement into the unwind station, thus reducing the weight lifted by the operator and simplifying the loading process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a complex mechanical support mechanism is used to handle spare rolls, then the handling capability is improved, but the device complexity and manufacturing cost increase

Engineering Contradiction:
Improvehandling capabilityVSAvoidmechanical complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The support structure is divided into two separate support elements instead of a single complex mechanism. Each support element independently supports one end of the spare roll, simplifying the overall structure while maintaining handling capability. This segmentation allows the system to achieve the same function with simpler, more manageable components.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The support structure enables the operator to manually load the spare roll by lifting only one end, while the other end is automatically supported by the second support element. This self-service approach allows the system to assist its own operation without requiring complex automated mechanisms, reducing device complexity while improving ease of operation.

Inventive Principle:
Principle #25Self-service

2Ease of operation

If a complex mechanical support mechanism is used, then handling capability is improved, but manufacturing and maintenance difficulty increase

Engineering Contradiction:
Improvehandling capabilityVSAvoidmanufacturing ease
Core Design Contradiction:
Ease of operationVSEase of manufacture

Solution Approach 1:

By dividing the support structure into two independent support elements, each element can be manufactured separately using simple, standard components. This segmentation eliminates the need for complex machining and assembly processes, significantly improving manufacturing ease and reducing production costs.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The support elements are designed as simple, inexpensive components that can be easily manufactured and replaced if needed. Rather than investing in a complex, expensive mechanical system, the invention uses straightforward support structures that prioritize manufacturing simplicity and cost-effectiveness over long-term durability.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

3Ease of operation

If the entire spare roll is lifted, then it can be moved to the loading position, but the weight to be lifted increases causing manual handling problems

Engineering Contradiction:
Improveease of loadingVSAvoidweight to be lifted
Core Design Contradiction:
Ease of operationVSWeight of moving object

Solution Approach 1:

The loading operation is segmented into two parts: one support element holds one end of the roll stationary, while the operator only needs to lift the other end. This segmentation of the lifting task reduces the weight the operator must handle from the entire roll weight to only half the roll weight, eliminating manual handling problems.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The first support element acts as an intermediary that holds one end of the spare roll during the loading operation. This intermediary support allows the operator to move the other end of the roll with reduced effort, as the intermediary bears part of the load and provides a pivot point for the loading motion.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

An agricultural round baler comprises a binding apparatus for feeding a binding material into a bale chamber and a support structure for supporting a spare roll of binding material in a storage position adjacent a side of the baler. The support structure includes a first support element that supports a first end of the spare roll while the spare roll is rotated from the storage position to a loading position, and a fixed second support element located adjacent the side of the baler.
