Solution Overview
Problem
Existing storage solutions for loads, such as metal decking in warehouses, face issues with rigidity, dirt and water retention, and complex welding processes, leading to weakened structures under repeated stress and insufficient resistance to bending.
Innovation Solution
A decking system comprising two mesh panels of metal wires, where the upper panel is reinforced by a second mesh panel with V-shaped folds, welded together to enhance rigidity and mechanical strength, and optionally reinforced with additional elements like wire, round iron, or angle iron between the panels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If sheet metal reinforcements are welded to the mesh panel, then the rigidity and bending resistance are improved, but the structure creates dirt and water retention zones and increases device complexity
Solution Approach 1:
The patent uses mesh panels with open structures instead of solid sheet metal reinforcements. The porous/mesh nature allows light, air, and water to pass through freely, preventing dirt and water retention while still providing the necessary structural reinforcement through the welded wire configuration
Solution Approach 2:
The reinforcement is applied locally at specific points where needed (at intersections and along critical edges) rather than using continuous sheet metal covers. This localized welding approach provides bending resistance only where structurally necessary, maintaining openness in other areas to prevent dirt accumulation
2Strength
If stays are welded to the longitudinal wires with spacers, then the rigidity is improved, but the structure weakens under repeated stress and increases manufacturing complexity
Solution Approach 1:
The patent integrates the reinforcement elements directly into the mesh panel structure by welding them at multiple points along the longitudinal wires, creating a unified structural system. This merging of reinforcement and panel into a single integrated structure distributes stress more evenly and eliminates weak points that would exist with separate spacer components
Solution Approach 2:
The reinforcement wires are welded to the longitudinal wires in advance during manufacturing, creating pre-stressed structural support that is ready to withstand repeated loading cycles from the beginning of service, rather than adding separate components that would require additional assembly steps
3Strength
If additional reinforcing elements are added between mesh panels, then the load-bearing capacity for heavy loads is improved, but the device complexity increases
Solution Approach 1:
Additional reinforcing elements such as angle irons or flat bars are added only at specific high-stress locations between the mesh panels, such as at the edges or at intervals along the span, rather than providing continuous reinforcement. This localized approach increases load-bearing capacity where needed while minimizing the number of additional components
Solution Approach 2:
The patent creates a composite structure combining mesh panels with supplementary reinforcing elements like angle irons or flat bars. This composite construction leverages the advantages of both the flexible mesh and the rigid reinforcement elements to handle heavy loads without requiring a complete redesign of the entire structure

AI summary
This decking comprises a panel (6) made of a mesh of metal wires welded together at their intersections. The panel (6) is associated with a second lower mesh panel (7), having parallel straight fold zones (12) extending over one principal dimension of said second lower panel (7), and projecting from the plane defined by said second panel.
