Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

The loading of wrap material rolls onto balers is cumbersome due to their large size, posing difficulties in managing and transferring them efficiently.

Innovation Solution

A transfer device with a pivoting arm and lifting mechanism is integrated into the baler, which allows for the lifting, lowering, and transferring of wrap material rolls, facilitating their efficient integration into the wrapping device.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of moving object

If wrap material rolls are made large to provide sufficient material supply, then the material supply duration is improved, but the ease of operation deteriorates due to difficulty in loading and maneuvering

Engineering Contradiction:

Improvematerial supply durationVSAvoidease of loading

Core Design Contradiction:

Duration of action of moving objectVSEase of operation

Solution Approach 1:

A transfer device with lifting mechanism acts as an intermediary between the ground and the baler chamber, enabling easy handling of large wrap material rolls. The transfer device includes a lifting mechanism that can raise and lower heavy rolls, and a transfer mechanism that moves them horizontally into position, eliminating the need for manual lifting and positioning by operators.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If wrap material rolls are made large to reduce frequency of replacement, then the productivity is improved, but the device complexity increases due to need for specialized handling equipment

Engineering Contradiction:

ImproveproductivityVSAvoiddevice complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The transfer device is designed with multi-functionality to handle various sizes and weights of wrap material rolls while integrating seamlessly with the existing baler system. The lifting mechanism can accommodate different roll dimensions, and the transfer mechanism can position rolls at various locations, making the system adaptable to different operational requirements without requiring multiple specialized devices.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Device complexity

If manual handling of wrap material rolls is used to minimize equipment, then the device complexity is reduced, but the loss of time increases due to cumbersome loading operations

Engineering Contradiction:

Improvedevice complexityVSAvoidtime for loading

Core Design Contradiction:

Device complexityVSLoss of time

Solution Approach 1:

The transfer device enables self-service handling of wrap material rolls through automated lifting and transfer mechanisms. The system can independently raise, lower, and position heavy rolls without requiring multiple operators or complex manual handling procedures, reducing both the time required for loading and the need for extensive equipment.

Inventive Principle:

Principle #25Self-service
