Fuel Tank Hinge Assembly Obstructed Pin Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fuel tank assemblies in vehicles lack a secure mechanism to prevent improper removal, which can lead to damage and safety issues during disassembly, especially for inexperienced users.
Innovation Solution
A hinge assembly with a hinge pin and hinge stay, coupled to a vehicular frame, and releasable hinge bolts that obstruct the hinge pin's removal, ensuring the fuel tank is properly detached by removing the bolts first, thereby preventing accidental damage and ensuring correct disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the hinge pin is made easily removable for simple disassembly, then the ease of operation is improved, but the reliability and safety deteriorate due to risk of improper removal and damage
Solution Approach 1:
The hinge bolt must be removed before the hinge pin can be accessed. This preliminary action ensures that the fuel tank is properly detached from the frame before the hinge pin is removed, preventing damage to the fuel hose and other components that would occur if the hinge pin were removed while the tank was still attached to the frame.
Solution Approach 2:
The hinge bolt acts as an intermediary component that controls the disassembly sequence. By positioning the hinge bolt to obstruct the hinge pin, it mediates the disassembly process to ensure proper procedure is followed, preventing improper removal and associated damage.
2Device complexity
If the hinge assembly allows direct removal of the hinge pin, then the device complexity is reduced, but harmful factors increase due to potential damage to the fuel tank and fuel hose
Solution Approach 1:
The hinge bolt serves as a protective intermediary that must be removed first. This simple additional component prevents harmful effects by ensuring the fuel tank is detached from the frame before the hinge pin is removed, eliminating the risk of damage to the fuel hose and tank.
Solution Approach 2:
The hinge bolt creates a preliminary barrier that prevents the harmful action of removing the hinge pin while the fuel tank is still connected to the frame. This preliminary anti-action eliminates the potential for damage before it can occur.

AI summary
A fuel tank assembly includes a hinge assembly, a fuel tank, and at least one hinge bolt. The hinge assembly includes a hinge pin and a hinge stay. The hinge pin pivotally couples the hinge stay to a vehicular frame and defines a hinge axis about which the hinge stay is pivotable with respect to a frame. The at least one hinge bolt releasably couples the hinge stay to the fuel tank such that the fuel tank is pivotable about the hinge axis. The at least one hinge bolt intersects the hinge axis and obstructs the hinge pin from being removed from the hinge stay.
