Fuel Filter Integration on Surge Pot Outer Wall
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fuel filter designs in vehicle tank modules are not exchangeable and require costly, time-consuming replacement when filter capacity is reached, especially in markets with contaminated fuels.
Innovation Solution
The fuel filter is integrated into the surge pot as an outer component, allowing for a compact design that reduces the internal height of the fuel tank and enables easy replacement by forming part of the surge pot's outer wall or being housed in a filter enclosure, eliminating the need for a separate filter cartridge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the fuel filter is integrated inside the surge pot or in an internal chamber, then the design is compact and material consumption is reduced, but the filter cannot be removed or replaced without disassembling the entire delivery unit
Solution Approach 1:
The fuel filter is segmented from the surge pot by positioning it externally on the outer surface, allowing the filter to be independently accessed and replaced without disassembling the entire delivery unit while maintaining a compact integrated design
Solution Approach 2:
The fuel filter is moved from an internal three-dimensional space to an external surface-mounted position, utilizing the outer surface of the surge pot as a mounting dimension, which enables easy access and replacement while maintaining compact overall dimensions
2Ease of repair
If the fuel filter is positioned external to the inner wall of the surge pot, then the filter can be easily replaced and maintained, but additional space is required outside the surge pot
Solution Approach 1:
The outer surface of the surge pot serves multiple functions: it acts as the boundary of the fuel containment chamber and simultaneously serves as a mounting surface for the fuel filter, eliminating the need for additional space while enabling easy filter replacement
Solution Approach 2:
The fuel filter mounting structure is merged with the surge pot housing, where the filter is positioned on and integrated with the outer surface of the surge pot, combining the functions of fuel containment and filter housing in a single structure
3Ease of repair
If the entire delivery unit is disassembled to replace the fuel filter, then the filter can be replaced, but the process becomes time consuming and costly
Solution Approach 1:
The fuel filter is extracted from the internal chamber and positioned externally on the surge pot surface, allowing the filter to be removed and replaced independently without disassembling the entire delivery unit, significantly reducing replacement time and cost
