Solution Overview

Problem

Existing methods for transporting formed agricultural bales from balers to storage or processing locations are inefficient due to the significant weight and susceptibility of bales and wrap material to damage, requiring substantial effort and introducing complications in farm operations.

Innovation Solution

A crop-package transfer system that includes a support frame with flexible members and a motive member, where the motive member is moved along the flexible members to transmit force to the bale, allowing it to be moved rearward and vertically upward, reducing the likelihood of damage by rolling rather than sliding, and enabling efficient transfer onto a trailing accumulator or wrapping device.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If bales are transported using traditional methods (sliding or dragging), then the transport effort is significant and damage occurs, but if rolling method is used via flexible members, then the effort is reduced and damage is minimized

Engineering Contradiction:
Improvedamage to bales and wrap materialVSAvoidcomplexity of transfer system
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

A flexible member (belt or chain) is introduced as an intermediary between the motive member and the bale. The flexible member contacts the bale indirectly through the roller, allowing the bale to roll along the flexible member rather than sliding across rough surfaces. This intermediary mechanism reduces direct friction and contact stress, minimizing damage to the bale and wrap material while enabling controlled transport.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system changes the physical state of motion from sliding to rolling. By using a roller that rotates along the flexible member, the bale is moved through rolling motion rather than sliding friction. This parameter change in the type of motion significantly reduces the force required and prevents damage to the wrap material, as rolling generates less heat and surface degradation compared to sliding.

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If bales are moved vertically upward from the baling chamber, then the bales can be transferred to trailing attachments, but the significant weight requires substantial effort

Engineering Contradiction:
Improveease of bale transferVSAvoidweight of formed bale
Core Design Contradiction:
Ease of operationVSWeight of moving object

Solution Approach 1:

The flexible member is configured to extend from a lower position near the baling chamber to a higher position where trailing attachments are located. By distributing the vertical lift along the inclined path of the flexible member rather than requiring vertical lifting, the system reduces the instantaneous force required. The roller moves the bale gradually upward along this inclined path, making the operation easier despite the bale's significant weight.

Inventive Principle:
Principle #12Equipotentiality

Solution Approach 2:

The flexible member acts as a mediator that distributes the lifting effort over a longer distance and time period. Instead of directly lifting the heavy bale vertically, the flexible member supports the bale's weight along an inclined path, allowing the actuator to apply force more gradually. This intermediary mechanism makes handling heavy bales easier by reducing peak force requirements.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Productivity

If bales are ejected far from the preferred storage location, then the baling chamber can operate continuously, but additional transport effort is required

Engineering Contradiction:
Improvebaling operation continuityVSAvoidtime for bale transport
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The flexible member with roller provides continuous transport capability from the baling chamber to the trailing attachment. As bales are continuously ejected from the baling chamber, the roller continuously moves them along the flexible member path. This continuous action eliminates idle time between baling cycles and transport operations, maintaining productivity while reducing the time each bale spends in transit through efficient, uninterrupted movement.

Inventive Principle:
Principle #20Continuity of useful action
