Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-pressure hoses connected using metal couplings often form multiple potential leakage paths, leading to reliability issues and environmental concerns, especially in submarine lines, where the rigid coupling sections hinder winding and storage.
Innovation Solution
A splicing method where the inner sealing liner is continuously bonded, and reinforcing plies are embedded in a rigid outer sleeve with overlapping plies to minimize rigid sections and prevent leakage, using vulcanization or adhesive bonding within a conical rigid sleeve.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If metal couplings are used to connect high-pressure hoses, then mechanical connection and sealing are achieved, but multiple potential leakage paths are formed and rigid sections hinder winding and storage
Solution Approach 1:
The invention merges the coupling function directly into the hose structure by splicing two hose ends together with overlapping reinforcing plies and adhesive bonding, eliminating separate metal coupling components. This integration removes the rigid coupling sections that hinder winding while maintaining sealing reliability through the bonded joint and overlapping plies configuration.
Solution Approach 2:
The invention uses the flexible hose structure itself with overlapping reinforcing plies and adhesive bonding to create the connection, replacing rigid metal couplings. The flexible nature of the spliced joint allows the hose to be wound and stored without the rigidity problems associated with metal coupling connections.
2Strength
If metal couplings with bonding are used to connect hoses, then mechanical bond is achieved, but at least three potential leakage paths are formed between couplings and liner
Solution Approach 1:
The invention combines the mechanical bond and sealing functions into a single integrated splicing structure where reinforcing plies from both hose ends overlap and are bonded together with adhesive. This eliminates the separate coupling components that create multiple leakage paths, providing both mechanical strength and leakage prevention through the unified bonded joint.
Solution Approach 2:
The invention extracts and eliminates the metal coupling components that create multiple leakage paths. By removing these separate coupling elements and directly bonding the hose ends with overlapping plies, the design reduces the number of potential leakage paths while maintaining the necessary mechanical bond strength.
3Ease of manufacture
If conventional splicing methods are used, then hose connection is achieved, but complex bonding elements and procedures are required
Solution Approach 1:
The invention merges multiple functions (mechanical bonding, sealing, and reinforcement) into a single splicing structure where overlapping reinforcing plies serve both structural and sealing purposes. This integration eliminates the need for complex separate bonding elements and procedures, simplifying the manufacturing process while maintaining connection integrity.

AI summary
A long-length hose spliced from two or more hoses containing an inner sealing layer, at least two spirally laid reinforcing plies, and a cover. A liner forming the inner sealing layer is formed by leak-tight splicing of liners of hoses to be spliced and the reinforcing plies are embedded into filling/adhesive material inside of a rigid outer sleeve, at the location of the splicing.
