Zigzag Multi-Diameter Tank Layout for Compact Fluid Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tank arrangements for storing pressurized fluid in electric vehicles require a large space and have inefficient storage due to large gaps between tanks, which affects energy efficiency.
Innovation Solution
A tank arrangement construction where tanks with different diameters are arranged in a zigzag pattern, with axes parallel to each other and connections aligned, allowing for fluid communication through a manifold, reducing space requirements and improving storage efficiency.

Engineering Contradiction Analysis
1Quantity of substance
If tanks are arranged in multiple stages (stacked vertically), then the arrangement can accommodate more tanks, but the space required in the stacking direction increases and gaps between tanks become large
Solution Approach 1:
The patent transitions from traditional vertical stacking (single dimension) to a multi-dimensional arrangement where tanks are positioned at different heights and depths, forming a zigzag pattern. This allows tanks to be arranged in three-dimensional space more efficiently, reducing the vertical space requirement while accommodating the same number of tanks.
Solution Approach 2:
The patent arranges tanks of different diameters in a nested-like configuration where smaller diameter tanks are positioned between and alongside larger diameter tanks. This nesting approach allows tighter packing and reduces gaps between tanks, improving space utilization in the stacking direction.
2Device complexity
If tanks are arranged in multiple stages with large gaps, then the arrangement is simpler, but the fluid storage efficiency deteriorates
Solution Approach 1:
The patent applies different arrangement strategies to tanks based on their local characteristics, specifically their diameter. Tanks of different diameters are positioned strategically - larger tanks form the outer structure while smaller tanks fill the gaps between them. This local optimization of positioning based on individual tank properties maximizes fluid storage efficiency without requiring a completely complex overall arrangement.

AI summary
A tank arrangement construction includes two or more first tanks and one or more second tanks are arranged such that tank axes thereof are parallel to each other with the connections are aligned on the same side. The first tanks are arranged in a first direction intersecting with directions of the tank axes. The second tank is offset from the first tanks arranged in the first direction, in a second direction intersecting the directions of the tank axes and the first direction. A diameter D1 of each first tank and a diameter D2 of each second tank are different from each other. The first tanks and the second tanks are arranged in a zigzag pattern. The first tanks and the second tanks lap each other as viewed in the first direction.
