Hydraulic Fluid Exchange Using Vacuum Filtration and Partial Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid change systems for automotive vehicles require complete evacuation to prevent mixing of solid waste and degraded oil with new material, which is time-consuming and increases mechanical risks, and there is a need for an efficient and environmentally friendly method to maintain engine health.
Innovation Solution
A device and method using at least two processing tanks, an air pressure regulator, a vacuum generator, and a connector to establish pneumatic and fluid connections for removing and reintroducing hydraulic fluid from the circulating system, with a suction hose connected to the lower region and a discharge hose connected to the upper region of the reservoir, facilitating filtration and conditioning of the fluid.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If complete evacuation of the fluid system is performed to prevent mixing of degraded oil with new material, then the purity of new fluid is improved, but the time required and mechanical risks increase
Solution Approach 1:
The patent divides the fluid change process into two independent stages: first removing only the lower portion of degraded fluid containing solid waste, then adding new fluid to the upper portion. This segmentation allows partial fluid replacement without complete system evacuation, reducing time and mechanical risks while maintaining adequate fluid purity for system operation.
2Reliability
If complete evacuation of the fluid system is performed to prevent sludge accumulation, then the long-term system health is improved, but the complexity and time of the procedure increase
Solution Approach 1:
The patent extracts and removes only the most problematic portion of degraded fluid - specifically the lower portion containing solid waste and sludge - rather than requiring complete evacuation of the entire fluid system. This targeted extraction approach maintains long-term system health by removing harmful contaminants while simplifying the overall procedure and reducing operational complexity.
3Productivity
If complete evacuation is performed to ensure thorough fluid replacement, then the effectiveness of fluid treatment is improved, but the risk of mechanical issues from inadequate refilling increases
Solution Approach 1:
The patent performs preliminary action by first removing degraded fluid from the lower portion of the reservoir before adding new fluid. This sequential approach ensures proper fluid replacement effectiveness while reducing mechanical risks, as the system maintains adequate fluid levels throughout the process and avoids the hazards associated with complete evacuation and subsequent refilling operations.
