Braided Net With Kink-Shaped Curves For High Strength
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing protective nets lack sufficient strength and deformability to effectively manage natural hazards and architectural applications while maintaining cost-effectiveness and ease of production.
Innovation Solution
The introduction of kink-shaped curves in elongated legs of the net, which are pressed against each other to form a flat surface shape, increases flexibility and strength, and the use of corrosion-resistant materials like stainless steel, along with articulated end connections, enhances the net's performance and visual appeal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional wire mesh structures are used, then production cost is reduced and manufacturing is simplified, but tensile strength and tear resistance are insufficient
Solution Approach 1:
The patent applies curvature by forming kink-shaped curves in the longitudinal elements of the net. These kinks create a three-dimensional structure with alternating bends that increase flexibility and strength. The curved geometry allows the net to deform under load while maintaining structural integrity, resolving the contradiction between strength and structural simplicity.
Solution Approach 2:
The invention transitions from a two-dimensional flat wire mesh to a three-dimensional structure by introducing kinks that protrude from the plane of the net. This dimensional change creates a more complex spatial configuration that enhances mechanical properties such as tensile strength and tear resistance while maintaining cost-effective production through standardized forming processes.
2Strength
If rigid wire mesh structures are used, then strength is improved, but deformability and flexibility are reduced
Solution Approach 1:
The kink-shaped curves introduce controlled curvature into the longitudinal elements, enabling the net to bend and deform flexibly while maintaining strength. The alternating kinks create a spring-like effect that allows the structure to absorb energy through deformation rather than rigid resistance, simultaneously achieving both strength and flexibility.
Solution Approach 2:
The patent creates a dynamic structure where the kinked longitudinal elements can deform under load and return to their original shape. This dynamic behavior allows the net to adapt to various loading conditions and environmental factors, providing both strength and deformability required for different applications.
3Shape
If simple flat mesh geometry is used, then manufacturing is simplified, but visual appeal and camouflage effect are reduced
Solution Approach 1:
The kink-shaped curves create an aesthetically pleasing three-dimensional pattern that provides visual appeal and camouflage effect in natural environments. The alternating bends form a distinctive geometric pattern that is more visually interesting than flat mesh while still being manufacturable through standardized forming processes using stamps or rolling equipment.

AI summary
A net, in particular for protection, safety, water-rearing or architectural purposes, is braided together from individual helically curved longitudinal elements (3) to form a braided structure. Individual longitudinal elements (3) curved into a cylinder or screw shape are twisted one inside the other with adjacent ones and compressed such that the braided structure is in more or less planar sheet-like form and the longitudinal elements (3) here each form more or less rectilinear limbs (8a, 8b; 9a, 9b) and curves (10a, 10b; 11a, 11b) therebetween. The curves (10a, 10b; 11a, 11b) between elongate limbs (8a, 8b; 9a, 9b) are inflected in kink form. This gives a net design with unexpectedly high strength values.
