Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hoses made of polyvinyl chloride or rubber are heavy, environmentally unfriendly, prone to brittleness and stickiness, and lack durability and flexibility, with reinforcement layers often separating during use.
Innovation Solution
A high-pressure hose design featuring an inner tube surrounded by two braided layers with misaligned imaginary axes, made of thermoplastic polyurethane and polyester fibers, providing enhanced pressure resistance, flexibility, and wear-resistance, with connectors made of stainless steel, aluminum, or copper for stable connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional hoses are made of polyvinyl chloride or rubber, then the material is readily available and easy to manufacture, but the hose becomes heavy and environmentally unfriendly
Solution Approach 1:
The patent employs composite materials consisting of thermoplastic polyurethane inner tube combined with polyester fiber braided layers. This composite structure achieves superior mechanical properties including reduced weight, enhanced flexibility, and improved environmental resistance compared to conventional single-material hoses made of polyvinyl chloride or rubber.
2Ease of manufacture
If conventional hoses are made of polyvinyl chloride or rubber, then the material is readily available and easy to manufacture, but the hose becomes prone to brittleness and stickiness reducing durability
Solution Approach 1:
The patent employs composite materials consisting of thermoplastic polyurethane inner tube combined with polyester fiber braided layers. This composite structure achieves superior mechanical properties including reduced weight, enhanced flexibility, and improved environmental resistance compared to conventional single-material hoses made of polyvinyl chloride or rubber.
3Strength
If reinforcement layers are added to improve structural strength, then the pressure resistance is improved, but the flexibility is reduced and layers may separate during use
Solution Approach 1:
The reinforcement structure is segmented into multiple independent braided layers, each with specific orientation and density. The first braided layer provides primary reinforcement while the second braided layer adds supplementary strength. This segmentation allows each layer to maintain flexibility independently while collectively providing enhanced structural strength, preventing the separation issues associated with conventional bonded reinforcement layers.
Solution Approach 2:
The patent employs composite materials consisting of thermoplastic polyurethane inner tube combined with polyester fiber braided layers. This composite structure achieves superior mechanical properties including reduced weight, enhanced flexibility, and improved environmental resistance compared to conventional single-material hoses made of polyvinyl chloride or rubber.
4Strength
If reinforcement layers are added to improve structural strength, then the pressure resistance is improved, but the hose becomes more complex in structure
Solution Approach 1:
The reinforcement structure is segmented into multiple independent braided layers, each with specific orientation and density. The first braided layer provides primary reinforcement while the second braided layer adds supplementary strength. This segmentation allows each layer to maintain flexibility independently while collectively providing enhanced structural strength, preventing the separation issues associated with conventional bonded reinforcement layers.

AI summary
A high-pressure hose includes 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.
