Fuel Pump Cover Ring Attachment for Fast Service Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle fuel pumps are exposed to environmental damage due to the lack of protective coverings, which complicates installation and repair processes, increasing manufacturing time and costs.
Innovation Solution
A cover assembly system with an annular cover ring and cover, featuring snap-fit connectors and clips for secure attachment to the pump mounting ring, allowing for rapid installation and removal, facilitating manufacturing and repair access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If protective coverings are added to fuel pumps, then protection against environmental damage is improved, but installation complexity and manufacturing time increase
Solution Approach 1:
The protective covering is divided into a cover portion and a pump mounting ring that can be separately installed. The mounting ring attaches first to the fuel tank, followed by the cover portion, allowing modular installation that reduces complexity while providing comprehensive protection against environmental factors.
Solution Approach 2:
The pump mounting ring is designed to be pre-installed on the fuel tank before the fuel pump itself. This preliminary action creates a prepared mounting structure with integrated attachment features, simplifying the subsequent installation of both the pump and protective cover as a unified assembly.
2Object-affected harmful factors
If protective coverings are added to fuel pumps, then protection against environmental damage is improved, but repair and replacement access is hindered
Solution Approach 1:
The protective cover is designed with dynamic attachment features including snap-fit connectors and removable clips that allow rapid detachment. This dynamic design enables the cover to be quickly removed for repair access and easily reinstalled, maintaining protection during operation while facilitating maintenance when needed.
Solution Approach 2:
The cover and mounting ring are designed as reusable components that can be temporarily removed during repair operations and then reinstalled. The attachment features allow for easy removal and recovery of the protective covering without damage, enabling repeated cycles of protection during operation and access during maintenance.
3Object-affected harmful factors
If protective coverings are added to fuel pumps, then protection against environmental damage is improved, but manufacturing time and costs increase
Solution Approach 1:
The protective system is segmented into separate components (cover portion and mounting ring) that can be independently manufactured and then quickly assembled. This segmentation allows for specialized manufacturing processes for each component while reducing overall assembly time through modular construction and pre-installed attachment features.

AI summary
A vehicle fuel pump assembly includes a fuel pump received in a tank opening, an annular pump mounting ring securing the pump to the tank at the opening, and a cover assembly including an annular cover ring and a cover. The cover ring is removably attached onto the underlying pump mounting ring and the cover is removably attached onto the cover ring to overly at least part of the fuel pump. The cover system can include a flexible attachment element on the cover ring engaging a peripheral notch in the pump mounting ring and clip elements securing the cover to the cover ring. The cover can include a hinge to provide pivoting of the cover or a portion of the cover with respect to the cover ring.
