Segmented Pressure Hose Restraint for Whip Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hoses and pipes under pressure tend to disconnect uncontrollably, leading to potential damage and injury due to whipping motion, which existing technologies have not adequately addressed to create a safe workplace and minimize equipment damage.
Innovation Solution
A method involving a hose or pipe segmented into multiple parts with elongate tethers and a zipper line system, where tethers are anchored to structures using loops and hitch methods to control movement and prevent whipping, with the zipper line providing redundancy in control measures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If hoses and pipes are used under pressure, then fluid transport function is improved, but safety deteriorates due to whipping motion upon disconnect
Solution Approach 1:
The hose or pipe is divided into multiple segments (at least three) with connection ends between them. This segmentation allows individual segments to be controlled by tethers, limiting whipping motion while maintaining overall fluid transport functionality. Each segment can be independently restrained without compromising the continuous fluid channel.
Solution Approach 2:
Elongate tethers are introduced as intermediary elements between hose segments and anchoring structures. These tethers act as mediators that restrict the movement of hose segments during pressure release, preventing whipping motion while allowing normal operation under pressure. The tethers transfer the restraining force from anchoring structures to the hose segments.
2Object-affected harmful factors
If tethers are added to control hose movement, then safety is improved, but device complexity increases
Solution Approach 1:
The elongate tethers serve multiple functions: they restrain hose segments during normal operation, provide controlled movement during disconnect, and can be anchored using various hitch methods (choke hitch, basket choke). The zipper line also provides multiple attachment points and redundancy. This multi-functionality reduces the need for additional specialized components.
Solution Approach 2:
The tether system is designed to be dynamic rather than rigid. The tethers allow controlled movement and adjustment, with anchoring structures that can accommodate varying positions. The zipper line provides adjustable attachment points, allowing the system to adapt to different operational conditions while maintaining safety.
3Reliability
If multiple tethers and anchoring structures are used, then control reliability is improved, but ease of operation deteriorates
Solution Approach 1:
The tether system is pre-configured with attachment points, loops, and hitch configurations before deployment. The zipper line is prepared with multiple attachment points, and the tethers are equipped with loops for easy connection. This preliminary preparation reduces the complexity of installation and adjustment during actual operation, improving ease of use while maintaining reliability.

AI summary
A method of controlling hoses and pipes (12) is provided. A hose or pipe (12) has at least three segments (14a, 14b, 14c) that are connected together to create joints (22a, 22b). The segments are connected such that fluid channels of the segments are in fluid communication with each other. An elongate tether (24) is positioned across each of the joints (22a, 22b). Each of the elongate tethers (24a, 24b) is attached to one of the segments adjacent the joint and the adjacent segment adjacent the joint. A zipper line (52) is provided to add additional control. The zipper line (52) has a first end connected to a first anchoring structure (38) and a second end connected to a second anchoring structure (38). The zipper line (52) is attachable to each of the elongate tethers (24a, 24b) attached to the at least three segments (14a, 14b, 14c).
