Protruding Metal Braided Net Structure for Stronger Mortar Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional metal braided nets have insufficient thickness and strength, leading to structural weakness and the need for additional spacer blocks that can reduce strength and increase labor costs.
Innovation Solution
A method of manufacturing a metal braided net with protruding thickness by intertwining and displacing wires to form hexagonal meshes and bending portions that protrude from the surface, allowing for increased thickness and strength without spacer blocks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If metal braided net with small thickness is directly attached to hillside or side slope, then attachment is simple, but cement mortar cannot have sufficient thickness leading to insufficient structural strength
Solution Approach 1:
The patent transforms the flat, two-dimensional metal braided net into a three-dimensional structure by forming protruding portions that extend perpendicular to the net surface. This dimensional change creates built-in spacing without requiring external spacer blocks, enabling sufficient cement mortar thickness while maintaining direct attachment to the hillside or side slope.
2Strength
If spacer blocks are disposed between metal braided nets and ground to raise the nets, then cement mortar can be fully filled and structural strength is enhanced, but more manpower is required for disposition of spacer blocks and large quantity of spacer blocks reduces structure strength
Solution Approach 1:
The patent extracts and eliminates the need for external spacer blocks by integrating the spacing function directly into the metal braided net structure through protruding portions. This removes the additional component and the associated manual disposition work, simplifying the construction process while maintaining structural strength.
Solution Approach 2:
The patent merges the spacing function with the metal braided net itself by forming protruding portions as an integral part of the net structure. This combination eliminates the need for separate spacer blocks and integrates multiple functions (structural support and spacing) into a single component.
3Ease of manufacture
If metal wires are wound around rotating mold to form metal wire product, then metal braided net can be produced, but metal wires must be of small diameter and adjacent metal wire products can only be hooked together by connecting bent portions resulting in insufficient strength
Solution Approach 1:
The patent applies preliminary action by forming protruding portions on the metal wires during the wire drawing process itself, before the wires are braided into the net structure. This pre-formed geometry enables stronger connections and larger wire diameters without requiring complex subsequent processing or small diameter wires.

AI summary
A method of manufacturing a metal braided net includes arranging a plurality of wires (1) to form a plurality of pairs of wires contiguous to each other (1a, 1b, 1c, 1d). An intertwining step (S2) is proceeded to intertwine each pair of wires (1a, 1b, 1c, 1d) a predetermined number of turns to form an intertwining portion (11). A displacement step (S3) is proceeded to make each pair of wires (1a, 1b, 1c, 1d) displace relative to each other through a predetermined distance. After an end of each of the plurality of wires (1a-1d) has formed an inclining portion (12), plural pairs of contiguous metal wires are formed (1b, 1c; 1a, 1d). The intertwining and displacement steps (S2, S3) are repeated to form a metal braided net having hexagonal meshes and a predetermined size. Then, a bending portion (2) is formed on each of the plurality of wires (1) and protrudes outward from at least one of an upper and a lower surfaces of the metal braided net. A metal braided net is also disclosed.
