Reinforced Hexagonal Net Weaving for High-Strength Cable Feeding
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 winding mechanisms, particularly with small diameters, restricting the production of nets with enhanced strength and durability.
Innovation Solution
A machine with a coiling mechanism for reciprocal coiling of wires and a feed system that includes a rotatable wire receptacle for reinforcing elements, allowing for the interweaving of high-strength wires, cables, or ropes into hexagonal meshes, along with a device for feeding cables of varying diameters, enabling the production of nets with increased strength and resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a small-diameter reel is used to wind reinforcing wires during net weaving, then the machine can operate with compact dimensions and the wire can be wound effectively, but high-strength wires and cables with greater rigidity and thickness cannot be wound around the reel
Solution Approach 1:
The reinforcing element feeding system is segmented into multiple independent containers (first container for wire, second container for cable or high-strength wire). Each container operates independently with its own feeding mechanism, allowing the machine to handle different types of reinforcing elements without requiring a single universal winding system that would compromise compactness or adaptability.
Solution Approach 2:
The system dynamically adapts between different feeding modes: for standard wires, the traditional reel-based winding is used; for cables and high-strength wires, the system switches to direct feeding from larger-diameter containers that accommodate the greater rigidity and thickness of these elements, allowing the machine to maintain compact operation while handling diverse reinforcing materials.
2Device complexity
If traditional wire feeding systems are used, then the machine structure remains simple and compact, but it is impossible to incorporate cables or high-strength wires with greater rigidity and thickness as reinforcing elements
Solution Approach 1:
The feeding system is divided into separate containers for different reinforcing element types. The first container feeds standard wires through the existing winding mechanism, while the second container feeds cables or high-strength wires through a dedicated feeding path that bypasses the small-diameter reel, thereby maintaining structural simplicity while enabling higher strength applications.
Solution Approach 2:
A specialized feeding mechanism acts as an intermediary between the second container and the net weaving process. This intermediary system includes guides and tensioning devices that accommodate the greater rigidity of cables and high-strength wires, allowing them to be fed into the weaving mechanism without requiring the entire machine structure to become complex.
3Adaptability or versatility
If a spool of suitable diameter for cables or high-strength wires is used, then these elements can be fed into the machine, but the solution becomes incompatible with the existing compact winding system for standard wires
Solution Approach 1:
The system uses separate feeding paths for different reinforcing element types. The first container with standard winding mechanism handles thin wires, while the second container with direct feeding mechanism handles cables and high-strength wires. This segmentation allows both systems to coexist without compatibility issues, maintaining the compactness of the original system while adding versatility.
Solution Approach 2:
The machine achieves multi-functionality by integrating two feeding systems into one platform. The first container and its winding mechanism serve standard wire applications, while the second container with its adapted feeding system serves cable and high-strength wire applications. Both systems share common structural support and control mechanisms, allowing the single machine to handle diverse reinforcing elements without requiring separate dedicated systems.

AI summary
A machine for manufacturing a reinforced net with hexagonal meshes including a plurality of permanently deformable wires, a reinforcing element, and a mechanism for the reciprocal coiling of first wires and second wires in twos. The mechanism has passages for the reinforcing elements, and a feed system for: the first wires, fed in from a plurality of containers mounted on board the machine and provided internally with a predetermined length of the first wires; for part of the second wires, fed in alternately with the first wires, so as to be interwoven therewith in twos in the coiling mechanism; and for the reinforcing elements, fed into the machine. For all the reinforcing elements, a wire receptacle is provided for one of the second wires, the wire receptacle being rotatable around the reinforcing element.
