Utility Vehicle Fuel System Bracket Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing configuration of fuel feed pumps and fuel system accessories in utility vehicles requires separate mounting and demounting brackets, leading to increased complexity and inefficiency in maintenance tasks.
Innovation Solution
A utility vehicle design where the fuel tank, fuel feed pump, and fuel system accessories are mounted to a single fuel system mounting bracket fixed to the seat frame, allowing simultaneous mounting, demounting, or maintenance by opening a seat plate, with the fuel tank protecting these components from the outside and facilitating fuel supply accessibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the fuel feed pump and fuel system accessory are mounted to the engine or chassis frame by way of different brackets, then the mounting structure can be simple, but the fuel feed pump and fuel system accessory need to be mounted or demounted individually, which increases the number of mounting components and causes troublesome work
Solution Approach 1:
The patent combines the fuel feed pump and fuel system accessory onto a single mounting bracket that is integrated with the seat frame. This merging allows both components to be mounted and maintained simultaneously as one unit, reducing the number of separate mounting operations and simplifying the overall mounting structure while improving operational ease.
Solution Approach 2:
The mounting bracket serves multiple functions: it mounts both the fuel feed pump and fuel system accessory, provides structural support, and integrates with the seat frame. This multi-functionality reduces the total number of components needed and simplifies the mounting structure while maintaining ease of operation.
2Volume of moving object
If the fuel tank is located in the lower space of the seat row, then the space utilization is improved, but the fuel feed pump and fuel system accessory need separate access for maintenance
Solution Approach 1:
By mounting the fuel feed pump and fuel system accessory on the same bracket within the lower space, they can all be accessed simultaneously by removing the seat plate. This merging of locations improves maintenance accessibility while maintaining efficient space utilization in the lower seat row area.
3Adaptability or versatility
If the fuel feed pump is located outside the fuel tank, then the fuel system configuration is flexible, but the number of mounting components increases and maintenance becomes more troublesome
Solution Approach 1:
The patent merges the mounting of the fuel feed pump and fuel system accessory onto a single bracket integrated with the seat frame. This reduces the number of separate mounting components needed while maintaining the flexibility of having the pump located outside the fuel tank, thus balancing adaptability with reduced complexity.
