Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If high-strength metal wires with increased resistance are used in rhomboid mesh nettings, then the strength and durability of the netting is improved, but the difficulty of construction and shaping increases substantially
Solution Approach 1:
The netting is divided into modular panels that can be manufactured separately and then assembled together. Each panel is constructed from standardized components that can be easily connected, reducing the overall construction difficulty while maintaining high strength through the use of high-strength wires in each module.
Solution Approach 2:
The high-strength metal wires are pre-formed into standardized components and panels before final assembly. This preliminary shaping and preparation of components reduces the difficulty of on-site construction, as the challenging forming operations are performed under controlled manufacturing conditions rather than during field installation.
2Strength
If high-strength metal wires with increased resistance are used in rhomboid mesh nettings, then the strength and durability of the netting is improved, but the resilience and ability to maintain desired form increases
Solution Approach 1:
The netting is divided into modular panels with standardized geometries. This segmentation allows each panel to be pre-formed to precise specifications and then assembled together, ensuring the overall structure maintains the desired form while benefiting from the high strength of the wire material.
Solution Approach 2:
The patent modifies geometric parameters of the rhomboid mesh, such as the angles and dimensions of the individual cells, to optimize the balance between resilience and form stability. By carefully selecting these geometric parameters, the netting achieves both the desired flexibility for installation and the stability needed to maintain its shape under load.
3Strength
If high-strength metal wires are used in rhomboid mesh nettings, then the resistance and durability is improved, but the weight and transport costs increase
Solution Approach 1:
The netting employs high-strength wires selectively in critical load-bearing regions and connections, while using lighter materials or reduced wire diameters in non-critical areas. This localized application of high-strength material maintains the necessary resistance and durability where needed while reducing the overall weight of the structure.
Solution Approach 2:
The patent utilizes composite construction combining high-strength metal wires with lighter supporting structures or anchoring systems. This composite approach allows the netting to achieve high resistance through the metal wire components while the overall structure maintains reduced weight through the use of lighter auxiliary materials.
4Strength
If high-strength metal wires are used in rhomboid mesh nettings, then the resistance is improved, but the complexity of machinery required for construction increases
Solution Approach 1:
The construction process is segmented into separate operations: panel manufacturing, component assembly, and field installation. This segmentation allows specialized, relatively simple machinery to be used for each discrete operation rather than requiring one complex machine to perform all functions, thereby reducing overall equipment complexity while still achieving high-strength construction.
Solution Approach 2:
Complex forming and shaping operations are performed in advance during panel manufacturing under controlled conditions. This preliminary action reduces the complexity of equipment needed during field installation, as the challenging operations are completed using standardized manufacturing equipment rather than requiring complex field machinery.

AI summary
A netting with rhomboid mesh, in particular for use in civil engineering in geotechnical applications, preferably in the field of protection from natural risks, is composed of elongate elements which are bent in the manner of a flattened spiral and are wound about adjacent elongate elements by half a revolution, that is to say by 180°. At least some of the elongate elements are ropes or strands which are each constructed with at least two metal wires which are helically wound about the same axis, wherein each metal wire has a diameter less than 3 mm.
