Detachable Fuel Supply Module for Easier Vehicle Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The maintainability of fuel supply systems in vehicles using gas fuel, such as hydrogen, is not adequately addressed, making maintenance cumbersome and inefficient.
Innovation Solution
A fuel supply module that includes a fuel tank, a regulator, a fuel output port, and a support that allows the module to be detachably attached to the vehicle, enabling maintenance as a single unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If the fuel supply system components are integrated into a single detachable module, then maintainability is improved, but device complexity increases
Solution Approach 1:
The fuel supply system is segmented into a detachable module that can be separated from the vehicle as a complete unit. This module includes the fuel tank, regulator, and associated components, allowing the entire assembly to be removed and replaced without disassembling individual components, thereby improving maintainability while managing complexity through functional grouping
Solution Approach 2:
The detachable module is designed as a universal assembly that performs multiple functions (fuel storage, pressure regulation, and supply) within a single integrated unit. This multi-functional design allows the module to be handled as one component during maintenance operations, simplifying the repair process despite the internal complexity of the integrated system
2Productivity
If the fuel supply module is detachably attached as a single body, then maintenance efficiency is improved, but attachment and detachment operations become more complex
Solution Approach 1:
The system is divided into a detachable module and the vehicle body, with the module containing all fuel supply components. This segmentation allows maintenance personnel to work on the complete fuel supply system by handling one modular unit rather than multiple separate components, significantly improving maintenance efficiency while the attachment/detachment mechanism manages the operational complexity
Solution Approach 2:
The module is pre-assembled with all necessary components (fuel tank, regulator, connections) before being attached to the vehicle. This preliminary assembly ensures that all connections and configurations are predetermined and standardized, reducing the complexity of attachment operations while maintaining high maintenance efficiency through quick swap capability

AI summary
A vehicle is driven by energy generated from a drive unit supplied with gas fuel, and includes a fuel supply module that includes a fuel tank in which the gas fuel is stored, a regulator that is connected to the fuel tank and adjusts the gas fuel output from the fuel tank to predetermined pressure, a fuel output port through which the gas fuel adjusted by the regulator is output, and a support that supports devices including the fuel tank, the regulator, and the fuel output port, and includes an attachment portion detachably attached to the vehicle while supporting the devices.
