Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Agricultural baler implements lack an efficient system for identifying and tracking the characteristics and properties of bales, such as weight, moisture content, and location, which hinders accurate communication and management of bale data to end users.
Innovation Solution
A baler implement equipped with a knotter system that wraps bales with a strand material, featuring a knotter sensor to detect movement and trigger a reader to emit an interrogation signal for a radio frequency identification (RFID) tag, allowing data association and communication to a remote memory, enabling tracking and identification of bale properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a baler implement uses traditional manual identification methods for bales, then the system complexity is low, but the ability to identify and track bale characteristics is insufficient
Solution Approach 1:
The patent replaces manual mechanical identification methods with an automated electronic system comprising RFID tags, readers, and a controller. The RFID tags attached to bales store identification data, which is automatically read by sensors and processed by the controller, eliminating the need for manual tracking and significantly reducing information loss while managing system complexity through automated integration.
Solution Approach 2:
The patent creates electronic copies of bale identification and characteristic data through RFID tags and digital records. Instead of physical manual tracking, the system generates digital replicas of bale information that can be stored, transmitted, and accessed remotely, enabling comprehensive tracking without proportionally increasing physical system complexity.
2Loss of information
If the reader continuously emits interrogation signals, then the identification data collection is comprehensive, but the energy consumption increases
Solution Approach 1:
The controller is configured to activate the reader to emit interrogation signals only at specific periodic intervals when a bale passes through the detection zone, rather than continuously. This periodic activation ensures comprehensive data collection at critical moments while significantly reducing overall energy consumption compared to continuous operation.
Solution Approach 2:
The system uses the movement of the bale itself to trigger the interrogation process. When the bale passes through the detection zone, the controller automatically activates the reader without requiring external intervention, ensuring data collection occurs naturally at appropriate moments while minimizing unnecessary energy expenditure.
3Reliability
If the baler implement includes multiple sensors and an RFID system, then the bale data tracking capability is improved, but the device complexity increases
Solution Approach 1:
The controller serves multiple functions: it activates the reader, receives identification data from RFID tags, collects bale characteristic data from sensors, associates this data with specific bales, and transmits information remotely. By making the controller a multi-functional central hub, the system achieves reliable comprehensive data tracking while avoiding the need for separate dedicated components for each function, thus managing overall system complexity.
Solution Approach 2:
The patent combines the identification system (RFID tags and readers) with the existing bale processing system (sensors and controller) into an integrated solution. Rather than adding completely separate systems, the identification components are merged with the operational components, allowing shared resources and coordinated functionality that improves reliability without proportionally increasing complexity.
4Loss of time
If the reader is automatically activated by the knotter sensor, then the timing precision for data association is improved, but the system complexity increases
Solution Approach 1:
The knotter sensor provides feedback about the bale processing state to the controller, which then automatically activates the reader at the appropriate moment. This feedback loop ensures precise timing for data association - the reader is activated exactly when needed based on real-time sensor input - while the automated control mechanism manages the complexity of coordinating multiple components through systematic signal processing.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables accurate and efficient identification and tracking of bale characteristics, improving data management and communication for bale producers and end users by associating bale data with unique RFID tags.
Implementation Method 1
A reader is in communication with the knotter sensor and is positioned to interrogate the identification tag. The reader is operable to emit an interrogation signal and receive an identification signal from the identification tag in response to the interrogation signal. In one aspect of the disclosure, the reader is a radio frequency identification reader, and the identification tag is a radio frequency identification tag.
Data Source
AI summary
A baler implement includes a housing that defines a baling chamber for forming crop material into a bale. The baler implement further includes a knotter system having a component that is moveable between a standby position and a wrapping position while wrapping the bale. A knotter sensor communicates a knotter engagement signal in response to movement of the component. A reader is in communication with the knotter sensor and is emits an interrogation signal for reading an identification tag on the bale. The reader emits the interrogation signal for a predefined period of time in response to the knotter engagement signal from the knotter sensor indicating movement of the component of the knotter system while wrapping the bale with the strand material.
