Detachable Fuel Tank Layout for Easy Connector Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fuel tank systems for hydrogen-powered vehicles require complex operations for installation and removal, involving multiple steps that complicate the process.
Innovation Solution
A fuel tank design featuring a handle on one end and a connector on the other end, allowing for simple installation and removal by gripping the handle and connecting/disconnecting the connector, with the connector recessed to prevent damage and exposure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the fuel tank is designed with a handle and connector at opposite ends, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The fuel tank is divided into distinct functional segments: a handle at one end for lifting and manipulation, and a connector at the opposite end for fuel supply connection. This segmentation allows each component to perform its specific function independently, improving operational ease without requiring complex integrated mechanisms.
Solution Approach 2:
The connector acts as an intermediary element that mediates between the fuel tank and the fuel-powered device. By placing the connector at the opposite end from the handle, the design creates a clear operational sequence: lift by handle, connect by connector, enabling simple two-handed operation without mechanical complexity.
2Reliability
If the connector is recessed into the fuel tank body, then the reliability is improved by preventing damage, but the ease of manufacture worsens
Solution Approach 1:
The connector is recessed into the fuel tank body in advance, creating a protective cavity before the connector is installed. This beforehand cushioning prevents the connector from being exposed to external damage during handling, storage, and operation, thereby improving reliability without requiring additional protective coverings or complex assembly steps.

AI summary
A fuel tank comprises a circular column-shaped fuel tank body, a handle, and a first connector. The circular column-shaped fuel tank body is provided so as to be detachably attachable to a fuel-powered device. The handle is formed on one end side in a length direction of the fuel tank body. The first connector is formed on another end side in the length direction of the fuel tank body and configured such that, by installing the fuel tank body to the fuel-powered device, the first connector is connected to a second connector provided at the fuel-powered device so as to enable fuel to be supplied to the fuel-powered device.
