Braided Tensile-Strength Hose for Deep Well Deployment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Deep well applications require hoses that can support their own weight and the weight of fluid and attachments without tangling or twisting issues, which existing technologies often fail to address effectively without additional winch cables or ropes.
Innovation Solution
A hose assembly with a tensile strength braided layer, including an inner core tube, reinforcement layers, a tensile strength braided layer with a specific braid pattern, and a cover layer, which provides longitudinal support and eliminates the need for additional winch cables or ropes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a hose is deployed in deep well applications without additional winch cable or rope, then the device complexity is reduced and ease of operation is improved, but the hose must provide sufficient tensile strength to support its own weight plus fluid and attachments
Solution Approach 1:
The patent combines the winch cable function and hose function into a single integrated structure. The tensile strength braided layer is incorporated directly into the hose assembly, merging two separate components (hose and winch cable) into one unified system that provides both fluid transport and tensile support capabilities
Solution Approach 2:
The hose assembly uses a composite structure with multiple layers including an inner core tube, reinforcement layers, a tensile strength braided layer, and a cover layer. This composite construction allows the hose to achieve the necessary tensile strength through the combination of different materials and structural layers
2Strength
If the hose is designed with sufficient tensile strength to support deep well applications, then the strength is improved, but the hose may become more rigid and difficult to deploy
Solution Approach 1:
The patent applies different properties to different parts of the hose structure. The tensile strength braided layer provides high strength and low elongation where needed, while the cover layer and inner core tube maintain flexibility and ease of deployment. Each layer is optimized for its specific function, allowing the overall assembly to be both strong and deployable
Solution Approach 2:
The patent specifies particular parameter ranges for the braided layer including braid angle (10° to 40°) and coverage value (20% to 50%). These parameter optimizations allow the braided layer to provide tensile strength while maintaining sufficient flexibility for deployment in deep well applications

AI summary
A hose assembly defines a longitudinal axis and includes an inner core tube, a reinforcement layer, a tensile strength braided layer, and a cover layer. The reinforcement layer surrounds the inner core tube and includes one or more filaments of a fiber. The tensile strength braided layer surrounds the fiber reinforcement layer and includes strands that form a braid pattern. A braid angle of the braid pattern is 10° to 40° relative to the longitudinal axis. A coverage value of the braid pattern is 20% to 50% relative to a surface of a layer adjacent the tensile strength braided layer. The cover layer surrounding the braided layer.
