Bale Identification Using Random 2D/3D Wrap Splotch Patterns
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bale identification systems, such as those using RFID tags and color-coded twine, are limited in their ability to uniquely identify bales due to narrow width and limited color variations, restricting the number of bales that can be tracked effectively.
Innovation Solution
A bale identification system that utilizes a computing device to analyze unique random splotch patterns on the wrap material, which can be two- or three-dimensional, applied during wrap material manufacture or application, allowing for increased variation and identification capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If RFID tags are attached to each bale, then bale identification capability is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent extracts the identification function from complex RFID systems and implements it through simple visual patterns on wrap material. The unique colored band patterns are applied directly to the wrap material during the baling process, eliminating the need for separate RFID tags and readers while maintaining bale identification capability.
Solution Approach 2:
The patent uses inexpensive colored bands applied to the wrap material as a disposable identification method. These bands are applied during the baling process and remain on the bale throughout its lifecycle, providing a low-cost alternative to expensive RFID tags without requiring complex reading equipment.
2Measurement precision
If color bands are applied to twine for bale identification, then identification capability is improved, but the narrow width of twine limits the number of unique patterns possible
Solution Approach 1:
The patent transitions from one-dimensional twine to two-dimensional wrap material surfaces. By applying colored patterns to the larger surface area of the wrap material rather than the narrow twine, the system dramatically increases the number of unique patterns possible while maintaining bale identification capability.
Solution Approach 2:
The patent merges the identification function with the wrap material application process. The colored bands are applied to the wrap material during the same operation that wraps the bale, combining the wrapping and identification functions into a single process step rather than requiring separate operations.

AI summary
A bale identification system includes an initial image sensor that is operable to capture an initial image of an initial bale bound with a wrap material. A computing device analyzes the initial image to identify a unique wrap characteristic on the wrap material of the initial bale in the initial image. The computing device may then associate the unique wrap characteristic with the initial bale and save the initial image and the associated unique wrap characteristic in a memory, such that the identified unique wrap characteristic of the initial bale is used as an identifier of the initial bale. The unique wrap characteristic may include a random two-dimensional and/or three-dimensional splotch pattern formed onto a surface of the wrap material.
