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 inadequate structural support when used in applications like hillside stabilization and concrete structures, where they cannot withstand increased pressure and require additional spacer blocks that reduce strength.
Innovation Solution
A method of manufacturing a metal braided net with a protruding thickness by arranging wires to form pairs, intertwining them, displacing them to create inclining portions, and repeating these steps to form hexagonal meshes, with bending portions protruding from the surface to increase thickness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a metal braided net with small thickness is directly attached to the hillside or side slope, then the attachment is simple, but the cement mortar cannot have sufficient thickness resulting in insufficient structural strength
Solution Approach 1:
The patent introduces protrusions that extend in the thickness dimension (z-direction) from the plane of the metal braided net. These protrusions create a three-dimensional structure that allows cement mortar to be applied with sufficient thickness while maintaining simple direct attachment to the hillside, resolving the contradiction between attachment simplicity and structural strength.
2Strength
If spacer blocks are disposed between the metal braided nets and the ground to raise the metal braided nets, then the cement mortar can be fully filled and structural strength is enhanced, but more manpower is required and a large quantity of spacer blocks reduces strength
Solution Approach 1:
The patent extracts the spacer function from separate spacer blocks and integrates it directly into the metal braided net structure through protrusions. This eliminates the need for separate spacer block components and their manual installation, reducing processing complexity while maintaining the ability to provide sufficient cement mortar thickness for structural strength.
Solution Approach 2:
The patent merges the spacer function with the metal braided net structure itself by incorporating protrusions that serve both as structural elements of the net and as spacers. This combination eliminates the need for separate spacer blocks, reducing both material quantity and installation complexity while maintaining structural strength.
3Ease of manufacture
If metal wires are wound around a rotating mold to form a metal braided net, then the production method is conventional, but the metal braided net has insufficient strength and cannot withstand larger pressure
Solution Approach 1:
The patent adds protrusions that extend in the thickness dimension from the conventional two-dimensional plane of the metal braided net. This three-dimensional structure increases the moment of inertia and structural rigidity, enabling the net to withstand larger pressures while maintaining compatibility with conventional wire winding manufacturing methods.
Solution Approach 2:
The patent creates a composite structure combining the base metal braided net with protruding elements that form a integrated composite structure. This composite design enhances pressure withstanding capacity by distributing loads more effectively across the three-dimensional structure while remaining manufacturable through conventional wire winding processes.

AI summary
A method of manufacturing a metal braided net includes arranging a plurality of wires to form a plurality of pairs of wires contiguous to each other. An intertwining step is proceeded to intertwine each pair of wires a predetermined number of turns to form an intertwining portion. A displacement step is proceeded to make each pair of wires displace relative to each other through a predetermined distance. After an end of each of the plurality of wires has formed an inclining portion, plural pairs of contiguous metal wires are formed. The intertwining and displacement steps are repeated to form a metal braided net having hexagonal meshes and a predetermined size. Then, a bending portion is formed on each of the plurality of wires 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.
