Fuel Filter Adapter for Spin-On Conversion Without Fuel Spillage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fuel filter systems require separate cartridge and spin-on bases, leading to inconvenient and time-consuming filter changes, often resulting in fuel spillages.
Innovation Solution
A fuel filter adapter that allows a spin-on fuel filter to be securely attached to a cartridge base, enabling interchangeability without disconnecting the canister base from the fuel-containing apparatus, using a coupler with threaded engagement and sealing surfaces to facilitate fluid connection and rotation prevention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate cartridge and spin-on bases are used for fuel filters, then filter compatibility and specialization are improved, but maintenance complexity and time consumption increase
Solution Approach 1:
The adapter body is designed with universal functionality to accept both cartridge filters and spin-on filters through different coupling mechanisms (threaded engagement for spin-on, direct fit for cartridge). This allows a single base unit to perform multiple filter types, eliminating the need for separate specialized bases and reducing maintenance complexity while maintaining filter compatibility options.
2Adaptability or versatility
If separate cartridge and spin-on bases are used for fuel filters, then filter specialization is improved, but maintenance time increases
Solution Approach 1:
The adapter assembly is segmented into modular components including the adapter body, coupling mechanism, and seal elements that can be independently assembled and disassembled. This segmentation enables quick attachment and removal of different filter types without requiring complete base replacement, significantly reducing maintenance time while preserving filter specialization through dedicated coupling interfaces.
3Adaptability or versatility
If filter base replacement is performed, then filter interchangeability is improved, but fuel spillage risk increases
Solution Approach 1:
The adapter incorporates pre-positioned seal elements and coupling mechanisms that ensure proper sealing is established before the filter is fully attached. The seal members are预先 placed in the adapter body to create a secure seal with the filter base, preventing fuel leakage during the interchangeability process and eliminating the need for complete base replacement that would expose fuel to spillage risks.
4Reliability
If threaded engagement is used for spin-on filter attachment, then securement reliability is improved, but assembly complexity increases
Solution Approach 1:
The adapter body serves as an intermediary component between the base and the spin-on filter, providing a standardized threaded engagement interface. This intermediary design simplifies assembly by allowing the threaded connection to be made at the adapter level rather than requiring complex threading at the base, while maintaining securement reliability through the robust threaded interface and integrated seal members.

Function Achieved in This Case
Enables seamless interchangeability between cartridge and spin-on filters, reducing maintenance time and minimizing fuel spillage during filter changes.
Implementation Method 1
The adapter body comprises a coupler, wherein the coupler extends along an axis and has a mount-engagement end and a filter-engagement end. The coupler comprises a threaded hole extending along the axis from the mount-engagement end toward the filter-engagement end, and an external thread extending along the axis from the filter-engagement end, wherein the external thread is configured to threadedly engage an internal thread of the spin-on fuel filter.
Data Source
AI summary
A fuel filter adapter has an adapter body having a coupler with a threaded hole extending from mount-engagement end toward a filter-engagement end. External threads of the coupler on the filter-engagement end engage an internal thread of a spin-on fuel filter. A coupler fluid passage extends through the coupler from the mount-engagement end to the filter-engagement end. A mount-facing surface of the adapter body defines a mount sealing surface, and has opposite filter-facing surface. A body passage of the adapter body extends between the mount-facing and filter-facing surfaces, and are positioned between the coupler and a peripheral region of the adapter body. One or more mount engagement members extend from the mount-facing surface, and selectively engage one or more contact surfaces of the mount to limit a rotation of the adapter body about the axis with respect to the mount. A gasket seals the mount sealing surface to the mount.
