Notched Chain Mail Cladding for Complex Curved Surfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Metal ring meshes struggle to tightly cover three-dimensional round shapes with varying radii due to limited stretchability in one direction, leading to material warping and aesthetic issues.
Innovation Solution
The metal ring mesh's less stretchable direction is aligned along a circular arc, with notches provided transversely to allow compression and indentations or recesses to ensure a taut fit, allowing for efficient covering of shapes with a balanced combination of running directions.

1Area of stationary object
If metal ring mesh is stretched to cover three-dimensional round shapes with varying radii, then the coverage area increases, but the material becomes warped and cannot maintain a tight fit
Solution Approach 1:
The metal ring mesh is divided into multiple strips with notches cut between them. These segmented strips can be independently compressed and shaped to conform to three-dimensional round shapes with varying radii, preventing material warping while maintaining tight fit. The notches allow the strips to be compressed without causing the entire mesh to warp.
Solution Approach 2:
Different regions of the metal ring mesh are given different properties through selective notching. The areas between notches maintain the original mesh structure for structural integrity, while the notched areas provide flexibility for compression and shaping. This local differentiation allows the mesh to adapt to varying radii while maintaining overall tight coverage.
2Manufacturing precision
If multiple parts are used to cover complex shapes, then the manufacturing precision improves, but the device complexity and assembly time increase
Solution Approach 1:
The notched metal ring mesh strip serves multiple functions simultaneously: it provides structural coverage, allows for compression adaptation to varying radii, enables tight fitting through notch compression, and reduces the need for multiple separate components. A single continuous strip with periodic notches can cover complex three-dimensional shapes that would otherwise require multiple separate pieces.
3Manufacturing precision
If the metal ring mesh is compressed to fit varying radii, then the tight fit is improved, but the material warps after maximum compression
Solution Approach 1:
By segmenting the mesh into notched strips, the compression is distributed across multiple independent segments rather than forcing the entire continuous mesh to compress uniformly. This prevents the material from warping after maximum compression, as each notched strip can be compressed independently to the required degree without exceeding material limits.

AI summary
A cladding element is formed from chain mail for cladding forms having different radii with the chain mail. For this purpose, the chain mail has at least one cut (10), which is connected at the edges (10a) thereof or to the edges of a further cut in order to clad the form. The chain mail has a running direction (L), in which the chain mail can be stretched to a substantially smaller degree, or cannot be stretched at all, compared to a direction running transversely thereto, preferably at a right angle. Because the chain mail with the running direction (L) is arranged along an arc of the form specified by the radius and has indentations (12) transversely to the running direction, wherein the connection takes place particularly along the edges (10a) of the cuts, three-dimensional round forms such as spheres or annular shapes or the segments thereof are clad efficiently.
