Fuel Filtration System With Series-Parallel Flow Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fuel filtration systems are inadequate in capturing contaminants, particularly in diesel fuel, leading to damage in engine and fuel injection components due to abrasive particles and water, and vary in cleanliness standards across jurisdictions, necessitating a more effective filtration solution.
Innovation Solution
A fuel filtration system incorporating an electric pump and a filter assembly with a filter exchange module featuring a mounting plate with externally and internally threaded connectors, forming a kidney filtration loop with conduits connecting the pump, filter assembly, and fuel tank, allowing for parallel and series fluid flow configurations and easy filter replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional fuel filters are used to capture contaminants, then some debris and water are removed, but fuel cleanliness standards cannot be consistently met across different jurisdictions and filter capacity is limited
Solution Approach 1:
The fuel filtration system is divided into multiple independent filters (typically three filters arranged in a triangular pattern on the filter assembly) that can be individually replaced. This segmentation allows the system to meet varying fuel cleanliness standards by adjusting the number and type of filters without redesigning the entire system, thereby improving adaptability while maintaining reliable filtration.
Solution Approach 2:
The filter assembly head is designed with a universal mounting structure that can accommodate different filter types and configurations. The quick-exchange mechanism allows a single filter assembly to serve multiple filtration requirements across different jurisdictions and applications, enhancing both adaptability and reliability.
2Reliability
If multiple filters are installed to improve filtration capacity, then contaminant capture increases, but filter replacement becomes more complex and time-consuming
Solution Approach 1:
The filter assembly contains multiple independent filters that are segmented into individual replaceable units. When maintenance is needed, only the contaminated filters require replacement while the filter assembly head and other filters remain in place, significantly reducing replacement time compared to replacing an entire filtration system.
Solution Approach 2:
The filter assembly is pre-configured with mounting plates, sealing elements, and alignment features that enable rapid installation. The pre-assembled nature of the filter module allows for quick exchange without requiring complex disassembly or realignment procedures, thus maintaining high filtration capacity while minimizing downtime.
3Reliability
If filters are tightly secured to ensure proper sealing and filtration, then filtration effectiveness improves, but filter replacement requires more effort and complexity
Solution Approach 1:
The filtering function is segmented from the mounting structure. Multiple filters are independently mounted on a common plate using standardized sealing and fastening mechanisms. This segmentation allows each filter to be securely sealed for effective filtration while enabling individual removal and replacement without affecting the structural integrity or sealing of other filters.
Solution Approach 2:
The mounting plate is pre-equipped with sealing surfaces, gaskets, and fastening mechanisms positioned to ensure proper sealing when filters are installed. This preliminary configuration maintains filtration effectiveness while simplifying the replacement process, as operators only need to remove fasteners and replace filters without complex sealing procedures.
4Volume of moving object
If a compact filter assembly is used to save space, then system size is reduced, but access for filter maintenance and replacement becomes difficult
Solution Approach 1:
The compact filter assembly uses a space-efficient triangular arrangement of three filters on a single mounting plate, minimizing the overall volume occupied by the filtration system. The segmented design allows each filter to be accessed individually from the same side of the assembly, maintaining ease of maintenance while achieving a compact footprint.
Solution Approach 2:
The filter assembly utilizes a two-dimensional triangular pattern on the mounting plate to arrange multiple filters in a compact configuration. This dimensional arrangement maximizes filtration capacity within a small volume while keeping all filter elements accessible from one side, eliminating the need for complex disassembly to reach filters.

AI summary
A fuel filtration system includes an electric pump, a filter assembly, and conduits for fluidly connecting the pump and filter assembly in series with a fuel tank to define a kidney filtration loop. The filter assembly includes a filter assembly head, including attachment openings therethrough, and a filter exchange module, including a mounting plate having externally threaded mounting connectors extending outwardly from one face thereof and internally threaded bores opening through another face thereof. In a mounted configuration, a fuel filter is threaded onto each mounting connector such that the filter is fluidly aligned with a fuel flow opening through the mounting plate, fasteners are positioned through the attachment openings and threadably received within the bores, and fuel flow passages of the filter assembly head define a flow distribution in which one pair of filters is fluidly in parallel and another pair of filters is fluidly in series.
