Solution Overview

Problem

Existing agricultural tools lack an efficient and economical method for handling and feeding mid-size or big bales to animals, particularly in terms of lifting, rotating, and distributing bales in a field setting.

Innovation Solution

A novel mid-size or big bale stack feeder bed wagon equipped with a bale loader arm assembly that can lift and rotate bales 90 degrees, and an interchangeable bale knife assembly for cleaving and distributing bale portions to animals.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a bale loader arm assembly is used to lift and rotate bales, then bale handling efficiency is improved, but device complexity increases

Engineering Contradiction:
Improvebale handling efficiencyVSAvoiddevice complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The accessory mount assembly is designed to accept both the bale loader arm assembly and the bale knife assembly, allowing a single mount structure to perform multiple functions. This reduces overall device complexity while maintaining high bale handling efficiency through the interchangeable assemblies.

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

Solution Approach 2:

The bale handling system is divided into separate interchangeable assemblies (loader arm assembly and knife assembly) that can be independently attached to the mount structure. This segmentation allows each assembly to be optimized for its specific function while simplifying the overall system through modularity.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If a bale knife assembly is used for distributing bale portions, then adaptability for feeding is improved, but device complexity increases

Engineering Contradiction:
Improveadaptability for feedingVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The accessory mount assembly serves as a universal interface that can accommodate both the bale loader arm assembly for lifting/rotating and the bale knife assembly for distributing. This multi-functional mount structure improves adaptability for different feeding operations without proportionally increasing device complexity.

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

Solution Approach 2:

The system allows dynamic reconfiguration by enabling the user to interchange between the loader arm assembly and knife assembly based on the specific feeding operation required. This dynamic adaptability allows the same base structure to handle multiple tasks effectively.

Inventive Principle:
Principle #15Dynamics

3Ease of operation

If interchangeable assemblies are used, then ease of operation is improved, but manufacturing complexity increases

Engineering Contradiction:
Improveease of operationVSAvoidmanufacturing complexity
Core Design Contradiction:
Ease of operationVSEase of manufacture

Solution Approach 1:

The system is segmented into a base mount assembly and interchangeable functional assemblies. This segmentation simplifies manufacturing by allowing each component to be produced independently using standard processes, while the modular design maintains ease of operation through simple attachment and detachment procedures.

Inventive Principle:
Principle #1Segmentation

AI summary

A stack feeder bed wagon is provided for pickup of one or more mid-size or big bales in an agricultural field for transport that simultaneously tilts and rotates a longitudinal bale 90 degrees upwardly and transversely over, adjacent, and along the forward upper edge of a stack bed for pushback onto the bed for transport or for consolidation with one or more bales into a single layer stack load on the bed that can be offloaded from the wagon for later pickup or that can be transported for deposit in a different place; and the wagon can be used for the retrieval of a load from a storage surface and when interchangeably equipped with a bale knife assembly that selectively cooperates with a bale moving crossfeed cable system can provide a series of bale segments to feed animals.
