Hydrogen Tank Layout Below Cabin for Working Vehicle Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Working vehicles with heavy structures like fuel tanks face challenges in maintaining weight balance due to their positioning, which can affect stability and efficiency.
Innovation Solution
The tanks are positioned below the cabin, with the drive device components, including the fuel cell and battery, arranged to optimize weight distribution, and the tanks are arranged in a concentrated manner along the vehicle's width or front-rear direction to maintain balance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the tank is provided in the vehicle body, then the gas storage function is achieved, but the weight balance of the vehicle deteriorates
Solution Approach 1:
The patent positions the tank in the vertical dimension below the cabin rather than distributing it horizontally throughout the vehicle body. This dimensional change allows the tank to be accommodated in the vertical space between the cabin and transmission case, achieving gas storage while maintaining horizontal weight balance across the vehicle.
2Quantity of substance
If the tank is positioned in the vehicle body, then the gas storage function is achieved, but the stability of the vehicle deteriorates
Solution Approach 1:
By placing the tank in the vertical space below the cabin, the patent achieves gas storage without compromising horizontal weight distribution. This vertical positioning maintains the vehicle's center of gravity within acceptable horizontal parameters, preserving vehicle stability during operation.
3Stability of the object's composition
If the tank is provided below the cabin, then the weight balance is improved, but the space utilization becomes more complex
Solution Approach 1:
The patent utilizes the vertical dimension between the cabin and transmission case to position the tank. This approach transforms a horizontal space utilization problem into a vertical space solution, simplifying the overall spatial arrangement while achieving optimal weight balance.
