Replaceable Oil Tank for Agricultural Machine Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Maintaining sufficient and clean engine oil in agricultural machines is challenging due to manual and time-consuming oil change processes, especially in remote locations, which poses health and environmental risks.
Innovation Solution
Agricultural machines equipped with a dock and a replaceable fluid container system that allows for easy fluid changes without specialized equipment or expertise, using a fluid distribution system to manage oil levels and quality, suitable for both wet and dry sump systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual oil draining and charging is used, then the power unit can be maintained, but the process is time-consuming and requires specialized equipment and expertise
Solution Approach 1:
The oil system is segmented into a permanent sump within the power unit and a removable oil tank. The oil tank can be detached and replaced independently, allowing rapid oil changes without draining the entire system manually. This segmentation enables the oil supply function to be separated from the power unit, facilitating quick maintenance while maintaining reliable lubrication.
Solution Approach 2:
Fresh oil is pre-filled into removable tanks off-site before being installed on the machinery. This preliminary preparation eliminates the time-consuming process of filling oil during field maintenance operations. The pre-filled tanks are simply docked into position, providing immediate oil supply without requiring specialized filling equipment or expertise at the maintenance location.
2Reliability
If manual oil draining is performed, then used oil can be removed, but the process is complex and requires skilled personnel
Solution Approach 1:
The oil system is divided into a permanent sump and a removable oil tank, allowing the bulk of the oil to be contained in the easily removable tank rather than dispersed throughout the power unit. This segmentation simplifies oil removal to a simple tank detachment operation rather than complex draining procedures requiring skilled personnel.
Solution Approach 2:
The oil storage function is extracted from the power unit and placed in a separate removable tank. This extraction allows the oil to be removed as a single unit by simply detaching the tank, eliminating the need for complex draining operations and specialized knowledge required for traditional oil change procedures.
3Reliability
If large volumes of oil are stored in the machine, then the power unit can be adequately lubricated, but the machine weight increases
Solution Approach 1:
The oil system transitions from a static, fixed-capacity sump to a dynamic, replaceable tank system. The removable oil tank can be exchanged when full, allowing adequate lubrication for extended periods without carrying excessive permanent weight. This dynamic approach enables the machine to maintain sufficient oil volume for reliable lubrication while avoiding the permanent weight penalty of an oversized fixed sump.
Solution Approach 2:
The oil capacity parameter is changed from a fixed, large-volume sump to a modular system where multiple smaller tanks can be sequentially replaced. This parameter change allows the machine to maintain adequate total oil volume for proper lubrication while reducing the instantaneous weight burden, as only one tank's worth of oil weight is carried at any given time rather than the total operational oil volume.
