Vacuum Oil Extraction Machine for Screw Damage Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Quick lube shops face liability issues due to technicians accidentally snapping off oil pan screws during oil changes, leading to oil leaks and the need for costly repairs or replacements, as they often rush the process and may not handle corroded or rusted screws properly.
Innovation Solution
An oil change machine that uses a vacuum source to directly suction used oil from the engine, eliminating the need to remove the oil pan plug and reducing the risk of screw damage, with adaptable hose assemblies for various engine types and an onboard offloading tank to streamline the disposal process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If technicians manually drain oil by removing the oil pan plug, then oil can be removed from the engine, but the risk of snapping off screws and causing oil leaks increases
Solution Approach 1:
The patent extracts the harmful action of manually removing screws and plugs by introducing a vacuum system that retrieves oil through alternative access points (dipstick tube, filler port), eliminating the risk of screw damage entirely while maintaining effective oil drainage
Solution Approach 2:
The vacuum system acts as an intermediary between the oil pan and collection container, transferring oil without requiring direct mechanical access to the oil pan plug or screws, thereby preventing screw damage while achieving complete oil removal
2Productivity
If technicians rush the oil change process, then productivity increases, but the likelihood of accidents and errors increases
Solution Approach 1:
The vacuum system performs the oil drainage operation autonomously without requiring technician intervention in the critical screw removal steps, allowing rapid operation while maintaining accuracy through automated vacuum-controlled retrieval
Solution Approach 2:
The system prepares for oil retrieval in advance by establishing vacuum pressure before connecting to the engine, enabling immediate oil extraction without manual intervention and ensuring accurate, complete drainage without rushing
3Productivity
If technicians remove the shroud or splash pan to access the oil pan plug, then oil can be drained, but the time required for oil change increases
Solution Approach 1:
The patent extracts oil through alternative access points (dipstick tube, filler port) that are already exposed on the engine, eliminating the need to remove the shroud or splash pan entirely, thereby reducing oil change time while maintaining drainage effectiveness
Solution Approach 2:
Instead of accessing the oil pan through the traditional route of removing the shroud and splash pan to reach the oil pan plug, the system inverts the approach by accessing the oil pan through existing openings (dipstick tube, filler port) using vacuum suction
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The oil change machine efficiently removes used oil without damaging engine components, reduces the risk of leaks and repairs, and saves time by allowing for on-site oil changes and efficient waste oil disposal, enhancing operational efficiency and reducing liability for quick lube shops.
Implementation Method 1
a pump for providing the vacuum source used to suction used oil from an engine
Implementation Method 2
vacuum generated by the pump can draw up oil through the suction line and into the pump

AI summary
An oil change machine or apparatus for removing used oil from an engine has flow lines for removing oil directly from the engine, which can be an automobile engine or a boat engine. The oil change machine can be configured to empty used oil to a designated waste oil bin. The oil change apparatus or machine can be located at a shop, can be portable and maneuverable from locations to locations, or be mounted on a service vehicle for on-site use, such as to perform oil change away from an oil lube center. The oil change machine can have adaptors for use with various engine models and can include an onboard offloading tank, in addition to a service holding tank, for performing multiple oil changes.
