Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current bypass filtration systems for engines and hydraulic systems are costly, labor-intensive to install, and require complex modifications, limiting their widespread adoption due to high energy and material requirements, despite offering benefits like extended oil life and reduced emissions.
Innovation Solution
A spin-on oil filter assembly that integrates a sandwich adapter with a through-flow orifice and remote filter head, allowing for quick and simple installation by redirecting engine oil flow through a high-efficiency bypass filter, eliminating the need for diverting oil and reducing labor and material costs, while maintaining a large filtering area for extended service intervals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional bypass filtration systems are installed, then fine particle removal capability is improved, but installation complexity and labor requirements increase significantly
Solution Approach 1:
The patent combines the bypass filter assembly with the spin-on filter as a single integrated unit. The bypass filter housing is positioned adjacent to the spin-on filter housing, and both filters receive oil from a common oil source through a T-connector, eliminating the need for separate installation of bypass filtration systems and reducing installation complexity while maintaining fine particle removal capability
Solution Approach 2:
The integrated filter assembly serves multiple functions: the spin-on filter provides full flow filtration for larger particles, while the bypass filter provides additional fine particle removal. Both filters operate simultaneously from a single oil source, making the system versatile and adaptable to different filtration needs without requiring complex modifications to the engine oil system
2Duration of action of stationary object
If traditional bypass filtration systems are installed, then oil service life is extended, but energy and material requirements increase
Solution Approach 1:
The bypass filter processes only a portion of the total oil flow rather than requiring the entire oil system to be modified. The T-connector diverts a fraction of oil from the common oil source through the bypass filter, which is sufficient to remove fine particles and extend oil service life without the energy and material requirements of complete system replacement
Solution Approach 2:
The integrated filter assembly acts as an intermediary between the oil source and the engine. By positioning both filters at the oil source and using a T-connector to distribute oil flow, the system extends oil life through enhanced filtration without requiring energy-intensive modifications to the existing oil circulation system
3Manufacturing precision
If fine filtration is implemented, then particle removal efficiency is improved, but pressure drop and pumping energy losses increase
Solution Approach 1:
The filtration system is segmented into two separate filter paths: full flow filtration for larger particles and bypass filtration for fine particles. This segmentation allows each filter to operate at optimized flow rates, reducing the pressure drop across individual filters and minimizing pumping energy losses while maintaining high particle removal efficiency across different particle size ranges

AI summary
The present invention teaches a method and apparatus to quickly and inexpensively implement advanced, bypass grade, fine, or additional filtration to engines and hydraulic systems. The present invention has the ability to make quick hydraulic connection to the engine or hydraulic system, where oil is super cleaned, without major modifications as is the paradigm by traditional bypass filtration systems and without removing any lubricant from the engine or system that the present invention is connected to, as is the paradigm of traditional bypass filtering systems. When connected to the normally provided stud for the spin-on oil filter in an engine or hydraulic system, the net effect of interest to the present invention is that by simply placing the adapter at the point of connection of the spin-on oil filter, many of the necessary plumbing associated with the traditional bypass filter installation is obviated, as is the energy and labor intensive process of seeking for a pressure point and a return of the oil. The present invention relies on the differential pressure effected by either alone or in combination of an orifice restriction to effect flow of either engine oil or hydraulic fluid, to route through a high efficiency filter, in trapping and low pressure to flow, an amount of dirty oil and then to return same amount to reconstitute a total flow on the system, whereby supplemental or advanced filtration is quickly connected to an engine or hydraulic system.
