Sliding Fuel Tank Assembly for Generator Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing generator fuel tanks require significant time and effort for inspection and maintenance, often necessitating detachment from the generator and may require multiple double-wall tanks to meet regulatory fuel capacity requirements, leading to complex and costly installations.
Innovation Solution
A fuel tank assembly with sliding engagement and access panels allows for easy removal and reconnection of fuel tanks from the shell, reducing maintenance time and complexity, while accommodating multiple tanks within a single shell to meet volume regulations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If generator fuel tanks are designed for secure containment, then fuel safety and containment are improved, but maintenance and inspection require significant time and effort
Solution Approach 1:
The fuel tank system is segmented into an inner fuel tank and an outer containment shell, allowing independent access to the inner tank through the access panel without compromising the outer containment structure. This segmentation enables maintenance of the inner tank while preserving the integrity of the overall containment system.
Solution Approach 2:
An access panel serves as an intermediary element between the outer containment shell and the inner fuel tank. This mediator allows service personnel to access and maintain the inner tank without detaching it from the generator or compromising the outer containment, thus reducing maintenance time while preserving fuel safety.
2Quantity of substance
If multiple double-wall fuel tanks are installed to meet regulatory volume requirements, then fuel capacity compliance is improved, but device complexity and installation cost increase
Solution Approach 1:
The invention merges the inner fuel tank and outer containment shell into a single integrated double-wall fuel tank assembly. This combination allows the system to meet regulatory fuel capacity requirements while reducing the number of separate parts and simplifying installation, as the entire assembly can be serviced as one unit through the access panel.
Solution Approach 2:
The outer containment shell serves multiple functions: it provides structural support, acts as a secondary containment barrier, and serves as the housing for the access panel mechanism. This multi-functionality reduces the need for additional separate components, thereby reducing device complexity while maintaining required fuel capacity.
3Stability of the object's composition
If fuel tanks are securely attached to generators, then operational stability is improved, but maintenance requires detachment and significant effort
Solution Approach 1:
The access panel extracts the maintenance function from the overall generator-fuel tank assembly. By providing a dedicated access point that can be opened independently, the system allows the inner fuel tank to be accessed and maintained without detaching it from the generator, thus maintaining operational stability while improving maintenance ease.
Solution Approach 2:
The access panel introduces a dynamic element to the otherwise static generator-fuel tank assembly. The panel can be opened and closed to provide temporary access to the inner tank, allowing the system to transition between a sealed stable state and an accessible maintenance state, thereby maintaining connection stability while enabling easy maintenance.

AI summary
A fuel tank assembly includes a shell defining an opening therein, an access panel connectable to the shell and movable between a closed position where the opening is closed and an open position where the opening is open, and a fuel tank disposed in the shell and slidably engaged with the shell. The fuel tank and the opening are dimensioned such that the fuel tank is slidable out of the shell via the opening when the access panel is in the open position. A generator assembly and a method of servicing a fuel tank of a generator are also described.
