Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless hose articles lack helical non-wire reinforcing members, which limits their structural integrity and flexibility, particularly in applications involving abrasion and fluid containment.
Innovation Solution
A hose article comprising a core layer, a helical PVC layer, an intermediate rubber reinforcing layer, and a rubber cover layer, with the helical PVC layer providing radial stiffness and the flexible layer allowing bending, while additional intermediate layers can include braided or knitted fiber structures for enhanced reinforcement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional wireless hose articles use polymer layers with braided fiber reinforcement, then structural strength is improved, but mass increases and flexibility decreases
Solution Approach 1:
The patent removes the heavy braided fiber reinforcement layer from the hose structure, extracting only the essential function of reinforcement. This is achieved by using the helical corrugated polymer layer configuration to provide structural support without the additional mass of wire or fiber braiding, directly resolving the contradiction between strength and weight.
Solution Approach 2:
The patent employs a helical corrugated layer configuration where the polymer material is formed into a three-dimensional helical structure. This curvature provides inherent structural reinforcement and rigidity comparable to traditional braided layers, while maintaining flexibility and reducing mass through the geometric efficiency of the helical form.
2Strength
If traditional wireless hose articles use polymer layers with braided fiber reinforcement, then structural strength is improved, but flexibility deteriorates
Solution Approach 1:
By removing the braided fiber layer entirely, the patent eliminates the source of flexibility restriction. The single-layer corrugated structure allows for greater angular deflection and bending capability compared to multi-layer braided constructions, as there are no rigid fiber elements to constrain the polymer matrix deformation.
Solution Approach 2:
The helical corrugated configuration inherently provides flexibility through its geometric design. The three-dimensional helical structure can accommodate bending and angular deflection more effectively than flat or braided configurations, as the corrugations can compress and expand in a controlled manner during flexing operations.
3Object-affected harmful factors
If traditional wireless hose articles use multiple polymer layers, then abrasion resistance is improved, but manufacturing complexity increases
Solution Approach 1:
The patent segments the reinforcement function from the containment function by using a single corrugated layer for structural support and a separate smooth polymer layer for fluid containment and abrasion resistance. This segmentation allows each layer to be optimized for its specific function while simplifying the overall manufacturing process compared to integrating multiple reinforced layers.
Solution Approach 2:
The patent uses composite material construction with a corrugated polymer layer providing structural reinforcement and a smooth polymer layer providing abrasion resistance and fluid containment. This composite approach achieves superior abrasion resistance compared to single-layer designs while maintaining manufacturing simplicity through the modular layering approach.
