Commercial Vehicle Fuel Tank Baffles Integrated Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fuel tank assembly methods for commercial vehicles are complex and require numerous external fastening elements, increasing weight and complicating the mounting process.
Innovation Solution
The fuel tank incorporates baffles with dual functions: preventing fuel sloshing and serving as attachment points to the vehicle, eliminating the need for external fasteners, straps, and tank carriers, and utilizing longitudinal struts for increased stability and flexible design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If external mounting elements (tank brackets, tension straps, rubber pads) are used to attach the fuel tank to the vehicle frame, then the fuel tank can be securely mounted, but the assembly process becomes complex and the overall weight increases
Solution Approach 1:
The baffle wall is merged with the mounting function by integrating mounting lugs directly into the baffle structure. This combines the fuel surge prevention function and the mounting function into a single integrated component, eliminating the need for separate tank brackets, tension straps, and rubber pads, thereby simplifying the assembly process while maintaining secure mounting
Solution Approach 2:
The baffle wall serves multiple functions: it prevents fuel sloshing, provides structural support, and acts as a mounting element through integrated lugs. This multi-functionality eliminates the need for dedicated mounting components, reducing both assembly complexity and overall weight while ensuring reliable attachment to the vehicle frame
2Reliability
If external mounting elements (tank brackets, tension straps, fasteners) are used to attach the fuel tank, then secure mounting is achieved, but the overall weight of the fuel tank system increases
Solution Approach 1:
The mounting function is merged into the baffle wall structure itself through integrated lugs. This eliminates the need for separate heavy components like tank brackets, tension straps, and multiple fasteners, significantly reducing the overall weight of the fuel tank system while maintaining secure mounting capability
Solution Approach 2:
The baffle wall serves as both a fuel surge prevention structure and a mounting element. By making the baffle wall multi-functional, the patent eliminates redundant components and reduces the total weight of the fuel tank assembly while ensuring reliable attachment to the vehicle frame
3Reliability
If multiple external fastening components are used, then the fuel tank can be securely attached, but installation space below the vehicle is consumed
Solution Approach 1:
The mounting lugs are integrated into the baffle wall structure, eliminating the need for external tank brackets and mounting frames that would occupy space below the vehicle. This integration frees up installation space while maintaining secure attachment capability through the streamlined design
4Reliability
If numerous external fastening elements are used, then secure mounting is achieved, but the number of parts increases requiring more assembly steps
Solution Approach 1:
The baffle wall and mounting lugs are combined into a single integrated component, reducing the number of parts from multiple separate fastening elements (brackets, straps, pads, fasteners) to a unified structure. This dramatically reduces the number of assembly steps and improves installation productivity while maintaining secure mounting
