Integrated Hose Coupling With Captive Nut and Bi-Directional Water Stop
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hose fittings for water technology in home and small business environments are complex, prone to misalignment and loss of parts, and often require multiple components for assembly, leading to user confusion and inefficiency.
Innovation Solution
A hose fitting with a combined hose holder and clamping device in one piece, featuring a captive pressure screw/nut and an oval resilient plastic circlip for secure coupling, along with a water stop designed for bi-directional flow to prevent misassembly and ensure consistent functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple separate components are used for hose connection (coupling, clamping device, pressure screw), then the connection can be secured, but the device complexity increases and parts may be lost or misaligned
Solution Approach 1:
The patent combines the coupling body, clamping device with gripping teeth, and pressure screw into a single integrated hose fitting component. This merging eliminates the need for separate parts that could be lost or misaligned, while maintaining the secure connection function through the integrated clamping mechanism that grips the hose and is tightened by the pressure screw.
2Reliability
If multiple separate components are used for assembly, then the connection can be secured, but the ease of operation decreases due to user confusion
Solution Approach 1:
By integrating all connection components into one piece, the patent eliminates assembly confusion. The user simply attaches the single integrated hose fitting to the hose and tightens the pressure screw, without needing to assemble multiple separate parts in the correct sequence and orientation.
Solution Approach 2:
The integrated design with the pressure screw directly accessible on the coupling body allows the user to perform the tightening operation themselves without requiring additional tools or assistance, simplifying the operation while ensuring secure connection.
3Reliability
If traditional hose fittings are used, then connection is possible, but time is lost due to complex assembly and disassembly processes
Solution Approach 1:
The integrated hose fitting combines all functional elements into one component that can be attached to and removed from the hose in a single operation, eliminating the multiple steps required when assembling separate components, thus reducing assembly and disassembly time while maintaining secure connection.

AI summary
The hose coupling (1) has a clamping device (42) formed with pins (34), lobes (35) and gripping gear teeth (36) in a finger like structure and provided with a ring like bead (44) on a side that is turned toward a hose (20) in a radial direction. The bead receives a hollow cylindrical pressure screw/nut (39) over a flanged socket (32). The hose is provided with a stopper for stopping the pressure screw/nut in an axial movement direction adjacent to tube-side boundary of a coupling rear part (51) of a base body such that the pressure screw/nut is arranged in a non-volatile and ridged manner.
