Reinforced Hexagonal Net Weaving for High-Strength Cable Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing machines for manufacturing hexagonal nets are unable to effectively incorporate high-strength wires, cables, or ropes as reinforcing elements due to limitations in reel diameter and twisting mechanisms, restricting the production of nets with enhanced puncture and traction resistance.
Innovation Solution
A machine design that accommodates high-strength reinforcing elements by using modified semi-cylindrical bodies with grooves and protrusions to manage cables of varying diameters, and a feeding device for cables, allowing for the integration of multiple longitudinal and transverse cables to form hexagonal meshes with increased strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a small-diameter reel is used to wind the reinforcing wire during weaving, then the machine can accommodate the twisting mechanism requirements, but high-strength wires and cables with larger diameters cannot be wound around it
Solution Approach 1:
The reinforcing element feeding system is segmented into multiple independent sources: a first reinforcing element source for the primary longitudinal reinforcing element, and a second reinforcing element source for the secondary reinforcing element. This segmentation allows each source to be optimized for different element types and diameters, resolving the contradiction between twisting mechanism compatibility and cable diameter accommodation.
Solution Approach 2:
The machine is designed with multi-functional capabilities to handle both traditional flexible reinforcing wires and modern rigid cables/ropes. The universal feeding system can accommodate various diameters and material types through adjustable tensioning devices and multiple feeding points, allowing the same machine to process different reinforcing element specifications without requiring diameter-matched reels.
2Device complexity
If traditional net manufacturing machines are used, then the weaving process is simple, but the nets lack enhanced puncture and traction resistance
Solution Approach 1:
The patent merges multiple reinforcing elements (first and second longitudinal reinforcing elements, and transverse reinforcing elements) into a single net structure. This combination of multiple strengthening components working together provides enhanced puncture and traction resistance while maintaining a weaving process that builds upon traditional methods, thus balancing device complexity with improved strength.
Solution Approach 2:
The net employs composite reinforcement structures where different types of reinforcing elements (wires, cables, ropes) are combined within the same net. This use of composite reinforcing materials allows the net to achieve superior mechanical properties including enhanced puncture and traction resistance, while the weaving mechanism remains relatively simple by processing these elements through standardized feeding and twisting operations.
3Strength
If high-strength cables or ropes are used as reinforcing elements, then the net gains enhanced strength, but the existing twisting mechanism cannot properly coil them together
Solution Approach 1:
The patent introduces intermediary components including guide rollers, tensioning devices, and positioning mechanisms that mediate between the high-strength cables/ropes and the twisting mechanism. These intermediaries facilitate the proper coiling and integration of rigid reinforcing elements by controlling their feed rate, tension, and positioning, making them compatible with the existing twisting mechanism while preserving their high strength properties.
Solution Approach 2:
The machine employs dynamic adjustment capabilities in the feeding and tensioning systems for high-strength reinforcing elements. The tensioning devices and feeding mechanisms can dynamically adapt to the specific properties of different cable or rope types, adjusting parameters such as feed speed, tension force, and positioning to ensure proper coiling and integration during the weaving process, thereby maintaining ease of manufacture across various reinforcing element types.
