Segmented Bale Wrap Assembly for Waste Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Agricultural balers generate waste from bale wraps, which are often made from non-biodegradable materials, leading to environmental concerns and inefficiencies in waste management.
Innovation Solution
A segmented bale wrap assembly where the bale wrap is disposed around a segmented shaft that couples and uncouples as the wrap is used, allowing the biodegradable segments to break off and biodegrade, reducing waste and facilitating easy disposal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional non-biodegradable bale wrap materials are used, then the bale wrap provides durable wrapping and securing, but it creates waste that is difficult to manage and environmentally harmful
Solution Approach 1:
The bale wrap assembly is divided into multiple segments that can be individually coupled and uncoupled. Each segment is designed to be biodegradable, allowing them to break down naturally after use. The segmented structure enables the wrap to be applied in portions, with each segment serving its purpose before being discarded or biodegrading, thus resolving the contradiction between durability and waste generation.
Solution Approach 2:
The bale wrap segments are designed as disposable, biodegradable components that can be easily discarded after use. Rather than attempting to recycle or reuse the entire wrap system, each segment is engineered to complete its function and then naturally decompose, eliminating the need for complex waste management systems and reducing environmental harm.
2Loss of substance
If a segmented bale wrap assembly is used, then waste is reduced through biodegradation, but the device complexity increases due to multiple segments and coupling mechanisms
Solution Approach 1:
The segmented shaft is divided into multiple identical or similar segments that can be coupled together using simple engagement features. Each segment is designed with standardized coupling interfaces, allowing them to be assembled and disassembled without complex mechanisms. This segmentation enables waste reduction through biodegradation while keeping the overall device complexity manageable through standardization.
Solution Approach 2:
The engagement features designed to couple the segments serve multiple functions: they provide mechanical connection during use, enable easy disassembly for waste removal, and facilitate standardized assembly. This multi-functionality reduces the need for additional specialized components, thereby limiting the increase in device complexity while achieving waste reduction goals.
3Ease of operation
If the segmented shaft is designed to uncouple easily, then waste management is simplified, but the structural stability during operation may be compromised
Solution Approach 1:
The coupling mechanism is designed with dynamic characteristics, providing strong mechanical connection during operation to ensure structural stability, but allowing for easy uncoupling when needed for waste management. The engagement features incorporate elements that naturally engage during wrapping operations and can be deliberately disengaged through simple actions, balancing stability during use with ease of operation for waste removal.
Solution Approach 2:
The engagement features are designed to allow selective extraction or removal of individual segments from the shaft assembly. This enables easy separation of used segments for waste management while maintaining the integrity of the remaining structure during operation. The extraction mechanism is integrated into the coupling design, allowing simple removal without compromising the stability of the assembled portion.

AI summary
A bale wrap assembly for an agricultural baler includes a segmented shaft having multiple segments configured to couple to one another along a rotational axis of the segmented shaft. The bale wrap assembly also includes a bale wrap configured to be disposed about the segmented shaft. Furthermore, the bale wrap assembly includes at least one engagement feature positioned at an end of the bale wrap and configured to engage the segmented shaft. The at least one engagement feature is configured to couple the segments to one another while engaged with the segmented shaft, and the at least one engagement feature is configured to disengage the segmented shaft as the end of the bale wrap moves away from the segmented shaft to enable the segments to uncouple from one another.
