Fluid Line Connector Bonding for High-Pressure Leak Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Fluid line devices in high-pressure tank systems face leaks and connection failures due to damage from tooth-like pressing members, which are insufficient to withstand high operating pressures.
Innovation Solution
The reinforcing elements in the fluid line are cohesively joined to the connecting piece using a joining connection, such as welding or adhesive methods, to enhance the strength and robustness of the connection, preventing leaks and failures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If tooth-like crimping elements are used to connect the connector to the fluid line, then the connection can be made firmly, but the reinforcing elements of the fluid line are damaged causing leaks or complete connection failure under high pressure
Solution Approach 1:
The patent replaces the mechanical crimping system (tooth-like pressing members) with a chemical bonding system (adhesive). The adhesive is applied to the inner surface of the socket and bonds the nipple to the fluid line, eliminating the mechanical damage caused by crimping elements while maintaining connection strength under high pressure
Solution Approach 2:
The patent introduces an adhesive as an intermediary substance between the nipple and the fluid line. This adhesive layer creates a chemical bond that connects the components without requiring mechanical deformation or damage to the reinforcing elements, thus preventing leaks and connection failure
2Force
If tooth-like crimping elements are pressed into the reinforcing elements, then the connector is firmly attached, but damage occurs to the fluid line and reinforcing elements leading to operational failures
Solution Approach 1:
The patent substitutes the mechanical pressing action with chemical adhesion. Instead of using tooth-like elements to mechanically grip and deform the reinforcing elements, an adhesive is applied to create a strong chemical bond, eliminating the harmful mechanical damage while achieving sufficient attachment force
Solution Approach 2:
The patent changes the bonding mechanism from mechanical (physical interlocking through deformation) to chemical (molecular bonding through adhesive). This parameter change in the bonding method eliminates the need for mechanical damage to achieve attachment, thereby reducing harmful effects on the fluid line and reinforcing elements
