Fluid Extractor Device with Vacuum Valve for Oil Filter
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid extractor devices for oil filters are inefficient in controlling the flow of oil, leading to messy spills and require expensive machining, making them difficult to manufacture and use.
Innovation Solution
A fluid extractor device comprising a ring with a clamp and a valve that securely fits around an oil filter, allowing controlled puncture and vacuum-assisted oil removal using off-the-shelf components, ensuring oil flows only when desired and is collected cleanly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a sharpened tip threaded screw is used to puncture the oil filter, then the oil can be drained through the channel, but the sharpened tip is large and difficult to puncture through the metal of the oil filter
Solution Approach 1:
The patent replaces the complex sharpened tip threaded screw with a simple push pin that can be easily obtained from an office supply store. The push pin is designed to be disposable - it is pushed through the oil filter and then removed with the filter, eliminating the need for manufacturing precision and complex machining while maintaining effectiveness.
Solution Approach 2:
The invention extracts only the essential function of puncturing from the complex screw mechanism. By using a simple push pin, the patent removes unnecessary complexity (threading, sharpening, machining) while retaining the core functionality of creating a puncture hole in the oil filter.
2Productivity
If the threaded screw penetrates the sidewall and enters the fluid containing cavity, then fluid can be drained through the channel, but oil flows through the channel immediately with no way to curb the flow
Solution Approach 1:
The patent requires the user to first position a receptacle in place before puncturing the oil filter. This preliminary action ensures that when the push pin creates the puncture and oil begins to flow, the receptacle is already ready to collect it, preventing spills and messes.
Solution Approach 2:
The patent introduces an engagement ring as an intermediary component that provides a mounting surface for the push pin and a structural framework for controlling oil flow. The engagement ring with its radially extending arms and channels acts as a mediator between the puncture point and the oil filter body, allowing controlled drainage.
3Productivity
If the engagement ring carries a threaded screw with channel, then fluid can be drained, but the pieces of the assembly require special machining making the assembly difficult to manufacture and expensive
Solution Approach 1:
The patent replaces expensive, specially machined components with inexpensive, off-the-shelf items. The push pin is a standard office supply, the receptacle can be a simple container, and the engagement ring is a basic mechanical component. This eliminates the need for special machining operations and reduces manufacturing complexity and cost.
Solution Approach 2:
The invention uses universal, multi-functional components that serve multiple purposes. The engagement ring provides structural support, mounting surfaces, and flow control channels. The push pin serves both as a puncture tool and as a temporary plug. These universal components can be obtained from standard suppliers rather than requiring custom manufacturing.
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 device allows for safe, complete, and clean removal of oil from oil filters, preventing spills and simplifying the disposal or recycling process, while being cost-effective and easy to use.
Implementation Method 1
attach a vacuum pump to the valve device to form a fluid extractor kit. When the vacuum pump is activated, oil is sucked out of an oil filter
Implementation Method 2
oil is sucked out of the oil filter to which the device has been applied
