Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for forming gas guide passages in high pressure gas containers, such as those used in fuel cell systems, require a large number of microspheres between the resin liner and the reinforcement layer, leading to increased manufacturing costs and time.
Innovation Solution
A high pressure gas container design featuring a resin liner, a reinforcement layer with an inner side reinforcement layer formed by stacked sections of a metal-reinforced tape with gas permeability, and an outer side reinforcement layer, where gas guide passages are formed between sections of the reinforcing member, allowing gas to be easily released through vent holes in the caps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If microspheres are provided between the liner and the reinforcement layer to form gas guide passages, then gas leakage is prevented, but manufacturing cost and time increase
Solution Approach 1:
The invention extracts the gas guide passage formation function from the microsphere assembly process and integrates it into the reinforcement layer structure itself. The reinforcing members are designed with inherent spacing that creates gas guide passages, eliminating the need for separate microsphere placement while maintaining gas leakage prevention functionality.
Solution Approach 2:
The invention merges the structural reinforcement function with the gas guide passage function into a single integrated component. The reinforcement layer both strengthens the container and provides gas guide passages through its construction, combining multiple functions into one element to simplify manufacturing.
2Reliability
If a considerable number of microspheres are used to form gas guide passages, then gas guide passages are effectively formed, but the operation requires time and effort
Solution Approach 1:
The reinforcement layer structure automatically creates gas guide passages through its own construction. The spacing between reinforcing members inherently forms the passages without requiring external assembly operations, allowing the structure to serve its own gas guide function.
Solution Approach 2:
The gas guide passages are pre-formed as part of the reinforcement layer design before final assembly. The reinforcing members are positioned and secured in a way that automatically creates the necessary spacing for gas guide passages, eliminating the need for subsequent microsphere placement operations.
3Ease of manufacture
If sections of reinforcing member are arranged alongside one another and stacked to form gas guide passages, then manufacturing is simplified, but structural integrity must be maintained
Solution Approach 1:
The invention uses composite material construction where multiple layers of reinforcing members are stacked and secured together. This creates both the gas guide passages through inter-layer spacing and maintains structural integrity through the composite nature of the reinforcement layer, combining strength with functionality.
Solution Approach 2:
The gas guide passages are formed in the radial dimension through spacing between reinforcing member layers, while the circumferential stacking maintains structural integrity. This dimensional approach allows passage formation without compromising the tangential strength of the container.

AI summary
In a high pressure gas container including a liner, a reinforcement layer, bosses (caps), and openings (vent holes), the reinforcement layer includes an inner side reinforcement layer that surrounds the liner, and an outer side reinforcement layer that surrounds the inner side reinforcement layer, gas guide passages that guide, to the openings (vent holes), a gas leaking from the liner are formed in the inner side reinforcement layer, and the gas guide passages are voids formed between sections of a reinforcing member by arranging alongside one another and stacking the sections of the reinforcing member along the liner.
