Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hoses made of polyvinyl chloride or rubber are unflexible and unfriendly to the environment, and are prone to deformation, and the flexibility of the hose, which are not durable to use. The existing technologies have not addressed the need for a high-pressure hose, which are not flexible and are not durable to use. The existing technologies have not addressed the need for a high-pressure hose, which are not flexible and are not durable to use. The existing technologies have not addressed the need for a high-pressure hose that is both flexible and durable, with conventional hoses being heavy, brittle, and lacking environmental friendliness.
Innovation Solution
A high-pressure hose design comprising an inner tube, a first braided layer, and a second braided layer, where the braided layers are made of polyester fibers with misaligned imaginary axes to provide structural reinforcement, flexibility, and wear-resistance, and are assembled without adhesives for ease of manufacturing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional hoses are made of polyvinyl chloride or rubber to provide basic hose function, then the hose can be manufactured easily, but the hose becomes heavy, unfriendly to environment, and lacks durability
Solution Approach 1:
The patent uses a composite structure consisting of an inner tube made of thermoplastic polyurethane and braided layers made of polyester fibers. This composite material approach provides both durability and environmental friendliness while maintaining ease of manufacture through standardized production processes for each layer.
Solution Approach 2:
The patent changes the material parameters from conventional polyvinyl chloride or rubber to thermoplastic polyurethane for the inner tube and polyester fibers for braided layers. This parameter change improves durability, reduces weight, and enhances environmental compatibility while maintaining manufacturability.
2Strength
If metal, plastic or fiber layers are added to reinforce structural strength, then the hose gains pressure resistance, but the flexibility is reduced and layers may separate during use
Solution Approach 1:
The patent uses thin film structures for both the inner tube and braided layers, where the inner tube is made of thermoplastic polyurethane and the braided layers use polyester fibers. These thin flexible structures provide necessary pressure resistance while maintaining hose flexibility and preventing layer separation through proper material selection and braided construction.
Solution Approach 2:
The composite structure of thermoplastic polyurethane inner tube combined with polyester fiber braided layers creates a synergistic effect where each material contributes its strengths - the inner tube provides flexibility and the braided layers provide pressure resistance - while maintaining overall hose flexibility through proper design.
3Strength
If adhesive materials are used to connect layers, then the structural strength is reinforced, but the manufacturing complexity increases and adhesive separation may occur during use
Solution Approach 1:
The patent extracts and eliminates the adhesive material from the hose structure. Instead of using adhesives to connect layers, the design relies on the mechanical interlocking of the braided layers with the inner tube, where the braided structure itself provides the connection function without requiring additional adhesive materials, thus reducing manufacturing complexity and eliminating adhesive separation issues.
Solution Approach 2:
The braided layers are designed to self-connect with the inner tube through their inherent mechanical interlocking structure. The braided construction allows the layers to hold each other in place through friction and geometric interlocking, providing self-service connection without external adhesives, thereby simplifying manufacturing and improving reliability.

AI summary
A high-pressure hose is provided, including: an inner tube, a first braided layer and a second braided layer. The inner tube defines an axial direction and a circumferential direction. The first braided layer includes a plurality of first braiding yarns and a plurality of first imaginary axes. Each of said first imaginary axes is passed through a plurality of first intersections of the plurality of first braiding yarns. The second braided layer is sleeved around the first braided layer and includes a plurality of second braiding yarns and a plurality of second imaginary axes. Each of said second imaginary axes is passed through a plurality of second intersections of the plurality of second braiding yarns. The plurality of first imaginary axes are at least partially misaligned with the plurality of second imaginary axes in a radial direction of the inner tube.
