Hydrogen Tank Mounting Frame Layout for Stable Work Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation of hydrogen tanks in work vehicles affects the vehicle's center of gravity, leading to instability during travel, particularly when transitioning from internal combustion engines to fuel cell systems.
Innovation Solution
A novel structure is developed to support the hydrogen tank on the vehicle body using an installation frame with upper and frame portions extending upward from opposite sides, providing stable support via front and rear support portions, allowing the tank to be positioned above the driver's seat without obstructing the cabin or protruding beyond the vehicle's wheels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the hydrogen tank is installed on the vehicle body, then the fuel cell system can be implemented, but the vehicle's center of gravity becomes unstable
Solution Approach 1:
The patent positions the hydrogen tank in the vertical dimension above the driver's seat rather than in conventional horizontal locations. This vertical placement, supported by the installation frame with upper and rear portions, resolves the contradiction by achieving fuel cell system integration while managing center of gravity through elevated positioning that maintains vehicle stability.
2Area of stationary object
If the tank is positioned above the driver's seat, then cabin space is maintained, but the tank may obstruct the cabin or protrude beyond wheels
Solution Approach 1:
The installation frame is designed with differentiated local structures: an upper frame portion positioned above the driver's seat to maintain cabin space, and a rear frame portion extending to the vehicle rear to prevent protrusion. This localized structural differentiation resolves the contradiction by allowing tank placement that preserves cabin area while preventing harmful obstructions through strategically designed frame extensions.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration ensures stable vehicle travel by evenly distributing the tank's load, maintaining cabin space, and preventing frame protrusions, thus enhancing operational stability and freedom in tank placement.
Implementation Method 1
a fuel cell, a tank configured to store hydrogen gas to be supplied to the fuel cell, The fuel cell generates electric power from the hydrogen gas supplied from the tank
