Multi-Cell Pressure Vessel Reinforcement for Rigidity and Expansion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pressure vessels face challenges in maintaining rigidity while allowing for the expansion of tank cells due to reinforcement members obstructing the expansion when filled in gaps between tank cells and fixation members.
Innovation Solution
A pressure vessel design with reinforcement members positioned on the inner surface of the fixation member, protruding towards adjacent tank cells, allowing for improved rigidity without obstructing expansion, and incorporating carbon fiber reinforced plastics for enhanced rigidity and vibration resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the gap between tank cells and fixation member is substantially filled with the reinforcement member, then the rigidity of the pressure vessel is improved, but the expansion of the tank cells is obstructed
Solution Approach 1:
The reinforcement member is positioned to extend only partially across the gap between tank cells and fixation member, rather than completely filling it. This partial action provides sufficient rigidity enhancement while leaving enough space for tank cell expansion, resolving the contradiction between structural strength and adaptability.
Solution Approach 2:
The reinforcement member is strategically positioned at specific locations where rigidity is most needed, rather than uniformly filling the entire gap. This localized approach maintains rigidity in critical areas while preserving expansion capability in other regions, addressing both requirements simultaneously.
2Strength
If the reinforcement member protrudes toward the tank cells, then the rigidity is improved, but the tank cell expansion is restricted
Solution Approach 1:
The reinforcement member protrudes only to a limited extent toward the tank cells, providing adequate rigidity support without completely blocking the expansion space. This partial protrusion achieves the necessary structural strength while maintaining sufficient volume for tank cell expansion during operation.
3Strength
If the reinforcement member is provided in the gap, then the rigidity is enhanced, but the size of the pressure vessel increases
Solution Approach 1:
The reinforcement member is designed with partial coverage in the gap area, providing sufficient rigidity enhancement without requiring the full gap space to be occupied. This reduces the overall volume increase of the pressure vessel while maintaining necessary structural strength.
Solution Approach 2:
The reinforcement member utilizes the existing gap space in three-dimensional space rather than adding external structures. By positioning it within the existing gap between tank cells and fixation member, the design enhances rigidity without significantly increasing the external dimensions or overall volume of the pressure vessel.

AI summary
A pressure vessel containing compressed fluid includes: a plurality of tank cells, each of the tank cells extending along a first direction and disposed along a second direction perpendicular to the first direction, each of the tank cells containing compressed fluid; and a sheet-like fixation member wound around a periphery of the tank cells and configured to integrally bind the tank cells. A gap extending along the first direction is provided between two of the tank cells adjacent to each other and the fixation member. A reinforcement member is provided on an inner surface of the fixation member, the reinforcement member extending in the gap in the first direction and protruding toward the two adjacent tank cells. A surface of the reinforcement member is positioned away from each of surfaces of the two adjacent tank cells.
