Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional agricultural harvesters require significant time and energy to activate the harvesting implement actuator, as it shares a primary power circuit with other systems like the threshing assembly, leading to inefficiencies.
Innovation Solution

Engineering Contradiction Analysis
1Ease of operation
If the primary power circuit is used to generate and supply hydraulic fluid to the harvesting implement actuator, then the harvesting implement can be adjusted, but other systems of the harvester must also be activated which requires significant time and energy
Solution Approach 1:
The power circuit is divided into a primary power circuit and an auxiliary power circuit. The auxiliary power circuit is specifically dedicated to powering the harvesting implement actuator, while the primary power circuit powers other harvester systems. This segmentation allows the harvesting implement to be adjusted independently without requiring activation of other systems, thereby reducing energy consumption and activation time.

AI summary
A system for adjusting harvesting implement position of an agricultural harvester includes a primary power circuit and an auxiliary power circuit each configured to selectively generate a flow of pressurized hydraulic fluid. Additionally, the system includes a hydraulic actuator including a cylinder, a first piston slidably positioned within the cylinder such that a first chamber is defined within the cylinder, and a second piston slidably positioned within the cylinder and movable relative to the first piston such that a second chamber and a third chamber are defined within the cylinder. Additionally, the hydraulic actuator includes a rod coupled between the first piston and the implement. Furthermore, when the flow of pressurized fluid from the auxiliary power circuit is supplied to the second chamber or the third chamber, the flow causes movement of the rod relative to the cylinder such that the position of the implement is adjusted.
