Auxiliary Power Control for Temporary Engagements in Farm Machines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Agricultural work machines face reduced performance due to power demands from operational adjustments such as temporary engagements, which occur when operating at or near the system power limit, affecting productivity and profitability.
Innovation Solution
Systems and methods for monitoring power demand and usage, identifying operational adjustments like temporary engagements, and adjusting power usage to prevent or reduce their deleterious effects by reducing or increasing power to auxiliary subsystems as needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the agricultural work machine operates at or near the system power limit to maximize productivity, then productivity is improved, but machine performance is reduced due to power demands from operational adjustments
Solution Approach 1:
The system performs preliminary identification of temporary engagements and proactively adjusts power usage before the operational adjustment occurs. The processor identifies when a temporary engagement will occur and adjusts auxiliary subsystem power usage in advance, preventing performance degradation while maintaining productivity during the engagement.
Solution Approach 2:
The system dynamically adjusts power usage to auxiliary subsystems based on real-time operational conditions. The processor continuously monitors power demand and temporarily modifies power allocation to auxiliary subsystems during identified temporary engagements, then restores normal power usage after the engagement completes, enabling flexible power management that maintains both productivity and performance.
2Reliability
If power usage is reduced to auxiliary subsystems during temporary engagements, then machine performance is maintained, but productivity may be affected
Solution Approach 1:
The system implements periodic power adjustment cycles that are synchronized with the duration of temporary engagements. Power is temporarily reduced only for the specific duration of the engagement event, then restored to normal levels. This periodic approach ensures performance is maintained during engagements while minimizing overall productivity impact by returning to full power operation immediately after each engagement.
3Adaptability or versatility
If the system monitors and adjusts power usage dynamically, then operational adjustments can be managed, but system complexity increases
Solution Approach 1:
The processor performs multiple functions using the same hardware components. The existing processor that controls primary agricultural operations is also utilized to identify temporary engagements and adjust auxiliary subsystem power usage. This multi-functional approach enables sophisticated power management capabilities without adding separate dedicated hardware systems, thereby limiting the increase in overall system complexity.

AI summary
An agricultural system includes one or more processors and memory storing instructions that, executable by the one or more processors. The instructions, when executed by the one or more processors, causing the one or more processors to identify a power usage across an agricultural work machine; identify a temporary engagement to be executed by the agricultural work machine; generate power usage adjustment instructions based on the temporary engagement; and control one or more auxiliary subsystems based on the power usage adjustment instructions.
