Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wire meshes lack sufficient durability and corrosion resistance, particularly in harsh environmental conditions, leading to increased maintenance and repair costs.
Innovation Solution
A wire mesh device composed of high-strength steel wires coated with a zinc-aluminum alloy corrosion protection layer, designed to withstand extreme conditions and maintain functionality for over 1680 hours in a climate change test, with a thickness of at least 215 g/m² and an aluminum content of approximately 5%, providing active anodic protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional wire meshes are used, then initial manufacturing cost is lower, but corrosion resistance and service life are insufficient
Solution Approach 1:
The patent applies composite materials by combining high-strength steel wire with a multi-layer corrosion protection coating system. The core wire provides mechanical strength while the zinc-aluminum alloy coating (5-11% Al) provides corrosion resistance. This composite structure resolves the contradiction by achieving both high reliability through corrosion protection and maintaining manufacturability through established coating processes.
Solution Approach 2:
The patent changes material parameters by specifying a zinc-aluminum alloy coating with aluminum content of 5-11% and mass per unit area of at least 215 g/m². These parameter specifications optimize the balance between corrosion resistance performance and coating application feasibility, resolving the contradiction between reliability improvement and manufacturing ease.
2Reliability
If thicker corrosion protection coating is applied, then corrosion resistance increases, but manufacturing cost and process complexity increase
Solution Approach 1:
The patent specifies precise parameter ranges for the corrosion protection coating: aluminum content of 5-11% and mass per unit area of at least 215 g/m². These parameter definitions enable optimized coating processes that achieve high corrosion resistance without excessive thickness, balancing reliability improvement with manufacturing simplicity.
Solution Approach 2:
The patent adopts established hot-dip galvanizing and zinc-aluminum alloy coating processes that are already industrially proven. By copying and adapting existing mature coating technologies rather than developing new complex processes, the patent achieves high corrosion resistance while maintaining manufacturing simplicity.
3Strength
If high-strength steel wire is used, then mechanical strength increases, but susceptibility to corrosion increases
Solution Approach 1:
The patent creates a composite structure where high-strength steel wire (tensile strength ≥800 N/mm²) serves as the load-bearing core, protected by a zinc-aluminum alloy coating layer. This composite material system resolves the contradiction by separating the functions: the steel core provides strength while the metal coating provides corrosion protection.
Solution Approach 2:
The zinc-aluminum alloy coating acts as an intermediary protective layer between the high-strength steel wire and the corrosive environment. This intermediate layer prevents direct contact between the steel and corrosive agents, resolving the contradiction between maintaining high strength and reducing corrosion susceptibility.
