Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The manual process of ejecting the last bale from a baler implement is time-consuming and inefficient, as it requires user intervention and lacks automated safety checks.
Innovation Solution
A baler system with an automated bale ejection sequence controlled by a processor that includes a bale ejection algorithm, which automatically forms the final bale, checks for safety conditions, and ejects the bale once the discharge location is clear, using a bale engagement member and actuator system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the manual last bale ejection process is used, then the user can eject the remaining crop material, but the process takes considerable time and requires manual intervention
Solution Approach 1:
The system performs the ejection operation automatically without requiring manual intervention. The processor executes the bale ejection algorithm to autonomously control the bale ejection system, making the system serve itself by detecting conditions and executing ejection without human assistance.
Solution Approach 2:
The processor performs preliminary safety checks and condition assessments before initiating the ejection sequence. The system evaluates discharge location clearance and safety conditions in advance, preparing the bale ejection system beforehand to execute the ejection operation efficiently when conditions are met.
2Extent of automation
If the automated bale ejection system is implemented, then the ejection process is automated and time is reduced, but the device complexity increases
Solution Approach 1:
The existing processor and control system are utilized to execute the bale ejection algorithm, making the control system multi-functional by handling both normal baling operations and automated ejection sequences. The bale ejection system integrates with existing baler components rather than requiring entirely separate dedicated systems.
Solution Approach 2:
The bale ejection system is merged with the existing baler structure and control architecture. The algorithm integrates safety checks, condition detection, and ejection control into a unified automated sequence that works alongside the existing plunger, knotter system, and discharge mechanisms.
3Reliability
If safety checks are performed before ejection, then the ejection is safer, but the process time increases
Solution Approach 1:
Safety checks and condition assessments are performed as preliminary actions before the ejection sequence is initiated. The processor evaluates discharge location clearance, safety conditions, and system readiness in advance, so that when ejection is commanded, the system can execute immediately without delays during the actual ejection process.
Solution Approach 2:
The system continuously monitors discharge location conditions and safety parameters, using feedback from sensors and system status to determine when ejection conditions are met. This feedback mechanism allows the processor to initiate ejection at the optimal moment when safety is confirmed, minimizing waiting time while ensuring safety.
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
The system automates the last bale ejection process, reducing time and effort while incorporating safety checks, ensuring quick and safe ejection of the final bale.
Implementation Method 1
The plunger is operable to compress crop material within the baling chamber into a formed bale
Implementation Method 2
The actuator is selectively controllable to move the bale engagement member into contact with the formed and bound bale within the baling chamber, and thereafter move the bale engagement member to eject the formed and bound bale from the baling chamber

AI summary
A baler system includes a baler controller includes a processor operable to execute a bale ejection algorithm to receive a command input to initiate a last bale ejection sequence. Upon receiving the command input, the baler controller automatically engages a knotter system to wrap and bind crop material currently disposed within a baling chamber to form a final bale. Upon forming the final bale, the baler controller automatically determines if a discharge location disposed proximate a discharge end of the baling chamber is clear of obstructions. Upon determining that the discharge end of the baling chamber is clear of obstructions, the baler controller automatically engages a bale ejection system to eject the final bale from the baling chamber and onto the discharge location.
