Pressure Sleeve Structure for Secure Flexible Hose Coupling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional methods for coupling flexible fluid lines are ineffective due to their tendency to move, bend, or deform under pressure, temperature changes, or vibrations, making it difficult to maintain a secure connection.
Innovation Solution
A pressure sleeve with a tubular portion, receiving portion, and coupling portion is used, where the tubular portion fits within the flexible hose, and the receiving portion extends outward to create a channel, allowing the sleeve to be secured with a fitting, thereby coupling the flexible hose to a component and preventing deflection or loosening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional coupling methods are used for flexible hoses, then the coupling process is simple, but the hose moves, bends, or deforms under pressure, temperature changes, or vibrations, resulting in insecure connections
Solution Approach 1:
The pressure sleeve is inserted inside the flexible hose, with the tubular portion positioned within the hose interior and the receiving portion extending outward. This nested configuration allows the coupling structure to be integrated within the hose assembly, providing secure anchoring against pressure, temperature changes, and vibrations while maintaining a relatively compact overall structure
Solution Approach 2:
The pressure sleeve is divided into distinct functional segments: the tubular portion for internal insertion and anchoring, the receiving portion for external fitting attachment, and the coupling portion for component connection. This segmentation allows each part to perform its specific function optimally, ensuring reliable connection security through the interaction of these specialized segments
2Stability of the object's composition
If a pressure sleeve with internal tubular portion is inserted into the flexible hose, then the hose is locked in place preventing deflection, but the coupling structure becomes more complex
Solution Approach 1:
The tubular portion of the pressure sleeve is inserted inside the flexible hose, creating a nested configuration where the sleeve's internal portion is positioned within the hose interior. This nesting provides stable anchoring that prevents hose deflection and movement under operational conditions while maintaining an integrated assembly
Solution Approach 2:
Different portions of the pressure sleeve have different structural characteristics optimized for their specific functions: the tubular portion has a configuration for internal anchoring, the receiving portion has features for external fitting attachment, and the coupling portion has structures for component connection. This local differentiation provides position stability through specialized local features rather than requiring complex overall structure

AI summary
An apparatus comprising a sleeve that comprises a tubular portion, a receiving portion, and a coupling portion. The tubular portion has an outer diameter that is substantially equal to an inner diameter of a flexible hose such that the tubular portion is capable of being inserted within the flexible hose. The receiving portion extends outward from the tubular portion to thereby define a channel between the receiving portion and the tubular portion for receiving an end portion of a flexible hose. The coupling portion is for coupling the sleeve, and thereby, the flexible hose, to a component.
