Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing containment devices for granular elements in reinforced soil structures face challenges in achieving uniform rigidity, leading to undesirable bulges and high costs due to the use of thick galvanized steel wires, which are difficult to produce and prone to corrosion.
Innovation Solution
A metal mesh panel with curvatures in multiple orientations, featuring electro-welded wires of varying diameters, providing increased rigidity without the need for additional galvanization and reducing metal usage, while allowing for adaptability in stress distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If thick galvanized steel wires are used to increase rigidity, then structural strength is improved, but manufacturing complexity and cost increase
Solution Approach 1:
The patent applies curvature to the metal mesh panel by forming at least one curvature in the mesh structure. This curvature transforms the flat mesh into a three-dimensional form, significantly increasing rigidity in multiple directions without requiring thicker wires or additional galvanization layers, thereby resolving the contradiction between strength and manufacturing complexity
Solution Approach 2:
The patent uses a composite structure combining metal mesh with curvature, where the geometric transformation complements the material properties. The curved metal mesh creates a structure that achieves high rigidity through form rather than material thickness, reducing the need for thick galvanized wires and simplifying manufacturing
2Reliability
If thick steel wires are used to prevent corrosion, then durability is improved, but material cost increases due to steel price volatility
Solution Approach 1:
The curvature transformation reduces the need for thick steel wires by deriving rigidity from geometric form. This allows the use of thinner, less expensive steel that still achieves the required structural performance and corrosion resistance, directly addressing the cost issue related to steel quantity
3Strength
If horizontal corrugations are added to increase rigidity in one direction, then strength in that direction is improved, but rigidity in other directions remains insufficient causing bulges
Solution Approach 1:
The patent forms at least one curvature in the metal mesh panel that provides rigidity enhancement in multiple directions simultaneously, unlike horizontal corrugations that only address one direction. This multi-directional rigidity prevents bulging while maintaining structural strength
Solution Approach 2:
The invention transitions from two-dimensional flat mesh with horizontal corrugations to a three-dimensional curved structure. This dimensional transformation adds rigidity in directions perpendicular to the original plane, achieving uniform rigidity distribution across all directions and preventing bulges
4Reliability
If galvanization is applied after mesh production, then corrosion protection is improved, but production complexity and time increase
Solution Approach 1:
The patent applies galvanization before forming the curvature in the metal mesh panel. This preliminary action allows the mesh to be pre-protected against corrosion before the complex curvature forming process, simplifying production workflow and reducing total production time while maintaining corrosion protection
