Supportive Fuel Delivery Module Reinforces Tank Walls
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Fuel tanks in vehicles experience deflections due to pressure and vacuum changes, which can lead to structural issues, reduced fuel storage volume, and increased material costs, especially when using non-supportive fuel delivery modules and thickened walls.
Innovation Solution
A structurally supportive fuel delivery module is integrated into the fuel tank, coupling to the upper and lower walls, providing structural reinforcement without adding internal elements, thus reducing deflections and allowing for thinner tank walls, thereby minimizing material costs and enhancing fuel efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If structural elements are included inside the fuel tank body to reinforce the tank, then fuel tank deflection is reduced, but fuel storage volume is reduced and material costs increase
Solution Approach 1:
The fuel delivery module is designed to perform multiple functions: it serves as both the fuel delivery system housing and as a structural reinforcement element for the fuel tank. The support member integrates structural support capabilities with fuel delivery components, eliminating the need for separate structural elements that would occupy fuel storage space.
2Strength
If fuel tank wall thickness is increased to reduce deflection, then structural integrity is improved, but material costs increase and fuel efficiency decreases
Solution Approach 1:
Instead of uniformly thickening the entire fuel tank wall, the support member provides localized structural reinforcement at critical areas where deflection occurs. This allows the fuel tank walls to maintain thinner, lighter construction while still achieving the required structural integrity through targeted support.
3Ease of manufacture
If non-supportive fuel delivery module is used, then fuel delivery function is maintained, but structural reinforcement is not provided leading to increased tank wall thickness requirements
Solution Approach 1:
The fuel delivery module is designed to perform multiple functions: it serves as both the fuel delivery system housing and as a structural reinforcement element for the fuel tank. The support member integrates structural support capabilities with fuel delivery components, eliminating the need for separate structural elements that would occupy fuel storage space.
