Bale Binder Material With Visual Stretch Tension Indicator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bale binder materials lack a reliable method to indicate when they are properly tensioned, leading to loose or deformed bales due to insufficient stretch, which affects the cylindrical shape and water shedding ability.
Innovation Solution
A bale binder material with a stretch indicator that changes visual states, such as color, shape, or size, to indicate when the desired tension is achieved, allowing operators to adjust the wrapping process accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the bale binder material is tensioned to achieve proper stretch, then the cylindrical shape and water shedding ability are maintained, but it is difficult to determine visually when the desired tension is achieved
Solution Approach 1:
The patent applies a stretch indicator coating that changes color based on the amount of stretch experienced by the bale binder material. When the material is properly tensioned to achieve the desired stretch, the coating transitions to a different color state, providing immediate visual feedback to operators that the correct tension has been achieved. This directly resolves the contradiction by enabling easy visual detection of proper tension while maintaining manufacturing precision.
2Productivity
If the bale binder material is not sufficiently tensioned, then the wrapping process is easier and faster, but the bale becomes loose allowing crop material to sag and deform
Solution Approach 1:
The stretch indicator provides real-time visual feedback during the wrapping process, allowing operators to immediately see when the desired tension level is reached. This feedback mechanism enables operators to apply the necessary tension quickly and accurately, maintaining cylindrical shape precision while maximizing wrapping productivity by avoiding excessive tensioning attempts.
3Manufacturing precision
If the bale binder material is over-tensioned, then the cylindrical shape is maintained, but the material may break or the bale may become too tightly bound
Solution Approach 1:
The color-changing stretch indicator provides a clear visual signal at the precise moment when desired tension is achieved, preventing operators from continuing to apply tension that could lead to material breakage or excessive tightness. This ensures reliable material integrity while maintaining the required cylindrical shape precision.

Function Achieved in This Case
Enables quick and easy determination of proper tensioning, ensuring the bale maintains its cylindrical shape and sheds water effectively by visually checking the stretch indicator's state.
Implementation Method 1
The stretch indicator may include a coating operable to change color based on an amount of stretch exhibited by the stretch indicator

AI summary
A bale binder for wrapping a cylindrical bale includes a sheet of wrap material and a stretch indicator disposed on the sheet of wrap material. The stretch indicator exhibits a stretch characteristic that is operable to change states based on an amount of stretch of the sheet of wrap material. The stretch characteristic of the stretch indicator exhibits a first state when the stretch indicator is disposed in an initial un-stretched condition. The stretch characteristic of the stretch indicator exhibits a second state when the stretch indicator is disposed in a desired stretch condition. The desired stretch condition includes a stretch magnitude that is greater than a pre-determined stretch value relative to the initial un-stretched condition.
