Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing oil filter assemblies lack a reliable mechanism for testing leaks, which can lead to harmful contaminants and oil leakage, compromising engine lubrication and potentially causing engine damage.
Innovation Solution
An oil filter-leak pressure-test station comprising an air pump, pressure gauge, vent valve, and manifold is used to apply pressure to the oil filter, allowing for the detection of leaks and determining the maximum pressure the filter can withstand, thereby ensuring its integrity and optimal design for the intended environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pressure testing is implemented to detect leaks in oil filters, then reliability of engine lubrication is improved, but device complexity increases due to additional testing equipment
Solution Approach 1:
The patent applies preliminary action by implementing pressure testing during the manufacturing process before the oil filter is deployed to the engine. The test station pressurizes the filter assembly with air or inert gas and submerges it in water to detect leaks beforehand, ensuring reliability is established prior to service use, thereby preventing engine damage from undetected leaks.
Solution Approach 2:
The patent uses water as an intermediary medium in the pressure testing process. The oil filter assembly is submerged in water during pressurization, and any leaks are detected by observing air bubbles emerging from the water. This intermediary approach allows non-destructive detection of leaks without requiring complex electronic sensors or measurement systems.
2Measurement precision
If comprehensive leak detection methods are used to identify all potential leaks, then measurement precision is improved, but difficulty of detecting and measuring increases due to subtle leak detection challenges
Solution Approach 1:
The patent employs visual observation of air bubbles rising through water as an indicator of leaks. This method transforms the invisible phenomenon of gas leakage into a visible signal that can be easily detected by operators. The bubble formation provides clear visual evidence of leak locations and severity, enabling precise detection without complex instrumentation.
Solution Approach 2:
The patent utilizes pneumatic pressure testing by introducing compressed air or inert gas into the oil filter assembly at controlled pressures. By pressurizing the system and submerging it in water, the method leverages pneumatic principles to force leaked gas to form visible bubbles, making even minor leaks detectable through simple visual observation rather than requiring sophisticated measurement devices.

AI summary
An apparatus and a method are provided for an oil filter-leak pressure-test station. The oil filter-leak pressure-test station comprises an air pump, a pressure gauge, a vent valve, an overflow reservoir, and a manifold configured to receive an oil filter. The oil filter-leak pressure-test station is configured to apply a desired internal air pressure to an oil filter for observing the oil filter assembly for any potential leaks, such as along a seal ring, rolled seam or a nut-end. The oil filter-leak pressure-test station is also configured to be mounted in a vise or similar mechanical attachment for observation to determine the extent or existence of any leak in the oil filter. The oil filter-leak pressure-test station may also be submerged in water using a submersion reservoir, so as to determine the existence and location of any leaks.
