Solution Overview

Problem

Existing agricultural apparatuses for distributing bale materials, such as straw, are limited in their ability to mount and spread bale material laterally to the direction of tractor movement, lacking the necessary structural strength and efficient conveyor systems to ensure effective distribution.

Innovation Solution

A bale handling apparatus featuring a box frame with a continuous conveyor belt, lateral support struts for mounting on a loader, and guide rollers to prevent bale strandage, along with a spreader head that ejects material laterally, powered hydraulically for efficient operation and adjustable roller tension.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the apparatus is designed with a box frame and conveyor belt system for lateral spreading, then the ability to spread bale material laterally to the direction of tractor movement is improved, but the structural strength and stability required for loader mounting deteriorate

Engineering Contradiction:
Improvelateral spreading capabilityVSAvoidstructural strength for loader mounting
Core Design Contradiction:
Adaptability or versatilityVSStrength

Solution Approach 1:

The apparatus is divided into distinct functional modules: a box frame for structural support and loader mounting, a conveyor belt system for bale transport, and a spreader head for lateral ejection. This segmentation allows each component to be optimized independently - the box frame provides structural strength while the conveyor and spreader enable lateral spreading functionality.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The apparatus transitions from conventional forward ejection to lateral ejection by reorienting the spreader head perpendicular to the direction of travel. This dimensional change in material ejection direction enables lateral spreading capability while the box frame maintains structural integrity for loader mounting.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Reliability

If guide rollers are added within the conveyor belt continuum to prevent strandage, then reliability of bale material distribution is improved, but device complexity increases

Engineering Contradiction:
Improvebale material distribution reliabilityVSAvoidconveyor system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

Guide rollers are introduced as intermediary elements within the conveyor belt system. These rollers act as mediators that redirect and guide bale material flow, preventing strandage and ensuring reliable distribution. The rollers integrate into the existing conveyor structure without requiring complete system redesign.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Strength

If horizontal support struts are added to provide structural strength for transverse carrying, then strength for loader mounting is improved, but weight of the apparatus increases

Engineering Contradiction:
Improvestrength for transverse carryingVSAvoidapparatus weight
Core Design Contradiction:
StrengthVSWeight of moving object

Solution Approach 1:

The support struts are constructed using high-strength, low-weight materials that provide the necessary structural strength for transverse carrying by the loader while minimizing weight increase. The composite construction allows the struts to bear heavy loads without proportionally increasing the overall apparatus weight.

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The support struts are designed with optimized curved profiles that distribute mechanical loads more efficiently throughout the structure. This curvature optimization provides maximum strength-to-weight ratio, enabling the struts to support transverse carrying loads while minimizing added weight.

Inventive Principle:
Principle #14Spheroidality (Curvature)

AI summary

A bale handling apparatus has a frame which retains a bale of material, a conveyor surface (14) mounted on the frame and upon which the bale rests, the conveyor surface being operable to move the bale toward a spreader head (16) that ejects bale material from the apparatus, wherein the apparatus includes at least one supporting strut (30), forming part of the frame and being located under the conveyor surface.
