Spring-Cable Hose Restraint for Live Pressurized Hose Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hose restraint devices require disconnection and shutdown of equipment for installation, leading to increased risk of contamination, environmental issues, and system downtime due to fluid leakage during installation.
Innovation Solution
A hose restraint device with a bendable cable, buttons, and link components that allows installation without disconnecting the hose from the fitting, using a spring mechanism to form loop-based connections around the hose and fitting, ensuring the device remains attached during operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a typical hose restraint device is installed by disconnecting the hose from the fitting, then the device can be properly installed, but equipment shutdown and fluid leakage occur leading to system downtime and environmental issues
Solution Approach 1:
The hose restraint device is pre-configured with a cable and link components that can be quickly attached to the hose and fitting without disconnection. The device is designed in advance to allow snap-fit or clip-based attachment during operation, eliminating the need for preliminary disconnection and shutdown procedures
Solution Approach 2:
The hose restraint device incorporates a flexible cable that can dynamically adapt to the hose movement and pressure changes during operation. The cable can be quickly tensioned and anchored to the hose and fitting while the system remains pressurized and operational, allowing installation without static shutdown
2Ease of manufacture
If the hose is disconnected for installation, then the restraint device can be installed, but fluid leakage and contamination risk increase
Solution Approach 1:
The restraint device is pre-assembled with all necessary components (cable, link components, anchoring mechanisms) before approach. This allows the installer to simply attach the pre-configured device to the operating hose and fitting without creating open connections that would lead to fluid leakage or contamination
Solution Approach 2:
The hose restraint device acts as an intermediary that can be attached to both the hose and fitting simultaneously during operation, creating a closed-loop restraint system that prevents fluid escape and contamination while maintaining the operational connection between hose and fitting
3Ease of manufacture
If the hose is disconnected for installation, then the device can be installed, but environmental issues are aggravated
Solution Approach 1:
The device is pre-configured with environmentally sealed components and quick-attach mechanisms that prevent fluid release during installation, eliminating the need to disconnect the hose and thereby preventing environmental contamination from pressurized fluid discharge
Solution Approach 2:
The design converts the potential harm of operating under pressure into a benefit by utilizing the existing operational state to demonstrate and validate the device's ability to restrain hoses during actual use conditions, while the quick-attach mechanism ensures no fluid is released during the installation process itself
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables installation without shutting down equipment, reducing fluid leakage and system downtime, while providing stable anchoring to prevent whip effects and ensure safety during operation.
Implementation Method 1
providing the hose restraint device with a spring, and in a state of operation of the hose in which the hose is continually connected to the fitting and carries the pressurized fluid, based on compressing the spring, bending the cable of the hose restraint device proximate the first end thereof around the hose, and bending the cable of the hose restraint device proximate the second end thereof over the fitting

AI summary
Disclosed are a method, a device and/or a system of a hose restraint device installable on a hose carrying a pressurized fluid and a fitting thereof during operation of the hose. In accordance therewith, the hose restraint device includes a cable and link components that receive portions of the cable bent around the hose and the fitting. The link components each includes a slot through which the cable passes and a notched slot in which a bent portion of the cable is received. Based on loop-based connections of the hose restraint device to the hose and the fitting, the anchoring of the bent portions of the cable to the link components is supplemented by a restoring force of a spring surrounding the cable and expanding between the link components of the hose restraint device to then be solely delimited thereby.
