Multi-use Fuel Tank Flange Assembly for Component Serviceability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fuel tank designs require substantial work to remove and replace components, leading to high repair costs and potential damage to the tank.
Innovation Solution
A multi-use fuel tank flange assembly that allows multiple components, such as a draw and return tube assembly, fuel filler neck, and cover plate, to be separately secured and removed using a single size flange with a lock ring and cam lock casting, enabling easy replacement and rearrangement of components without damaging the tank.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If components are secured directly to the fuel tank, then the structural strength is improved, but the ease of repair deteriorates
Solution Approach 1:
The fuel tank assembly is segmented into a permanent tank structure and removable component modules (draw/return tube assembly, fuel filler neck, pressure valve assembly) that can be independently removed and replaced without damaging the tank or requiring substantial repair work
Solution Approach 2:
A flange assembly with lock ring mechanism serves as an intermediary between the fuel tank and components, providing a secure yet removable connection that maintains structural strength while enabling easy repair and replacement
2Reliability
If multiple components are secured directly to the fuel tank, then the reliability is improved, but the loss of time deteriorates
Solution Approach 1:
The connection system transitions from a static permanent attachment to a dynamic removable attachment, allowing components to be quickly removed and reinstalled via the flange and lock ring mechanism, significantly reducing service time while maintaining operational reliability
3Stability of the object's composition
If components are permanently attached to the fuel tank, then the stability of the object's composition is improved, but the adaptability deteriorates
Solution Approach 1:
The flange assembly with lock ring provides a universal mounting interface that can accommodate multiple different component types (draw/return tube assembly, fuel filler neck, pressure valve assembly) and allows for easy reconfiguration and rearrangement of components based on different operational requirements

AI summary
A multi-use fuel tank flange assembly facilitates the attachment and removal of multiple components thereto, such as a draw and return tube assembly, a fuel filler neck, and a cover plate. Each of these components may be removed from the flange without damage to the component, the flange or the fuel tank. Multiple flanges may be used on a single fuel tank to allow multiple components to be secured to the single fuel tank.
