Agricultural Implement Weight Transfer Feedback Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing agricultural implements face challenges in maintaining load balance across wheel assemblies, leading to soil compaction and reduced yield due to uneven weight distribution, particularly when product is consumed during operation, as existing weight transfer systems lack feedback control to adjust weight transfer dynamically.
Innovation Solution
A weight transfer system with a feedback control mechanism that uses load cells and hydraulic cylinders to continuously monitor and adjust the weight distribution across wheel assemblies, ensuring balanced loads by transferring weight from the main frame section to wing sections based on real-time product consumption data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If weight transfer systems are used to balance load across wheel assemblies, then soil compaction is reduced, but the system complexity increases due to lack of feedback control
Solution Approach 1:
The patent implements a feedback control system that uses load cells to measure the actual weight distribution on wheel assemblies and compares it to target values. The controller adjusts hydraulic cylinder pressure based on this feedback to maintain optimal load balance, resolving the contradiction by adding intelligence to the weight transfer system without excessive complexity
Solution Approach 2:
The system automatically monitors and adjusts its own weight distribution using load cell measurements and hydraulic actuation without requiring manual intervention. The feedback control enables the system to self-correct imbalances as product is consumed, reducing soil compaction while keeping operational complexity manageable
2Device complexity
If fixed weight transfer is used, then device complexity is reduced, but load balance deteriorates as product is consumed during operation
Solution Approach 1:
The patent transitions from fixed weight transfer to dynamic weight transfer by continuously adjusting hydraulic cylinder pressure based on real-time load cell measurements. This allows the system to adapt weight distribution as product is consumed, maintaining load balance throughout operation while using manageable complexity through automated control
Solution Approach 2:
The system changes the parameter of weight transfer amount dynamically rather than maintaining a fixed setting. The controller adjusts the degree of weight transfer based on measured load conditions and product consumption rate, ensuring optimal load balance adapts to changing operational conditions
3Device complexity
If no weight transfer system is used, then device complexity is minimized, but productivity decreases due to reduced yield from soil compaction
Solution Approach 1:
The feedback control system using load cells provides continuous information about weight distribution to the controller, which adjusts hydraulic pressure to maintain optimal load balance. This intelligent control enables the system to improve yield through reduced soil compaction while keeping the added complexity justified by the productivity gains
