Wire Mesh Posts for Noise Walls
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing noise protection and partition walls face challenges with stability, flexibility, and aesthetics due to the use of solid steel posts, which are costly, visually unattractive, and require complex connections, while also being inflexible and prone to horizontal deflection.
Innovation Solution
The use of wire mesh posts with screw-clamp fastening elements allows for a lightweight, inexpensive, and adaptable wall system that can be easily assembled and customized, featuring a grid pattern that enables the use of smaller grain sizes for filling material and provides enhanced stability through stiffening elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If solid steel posts are used to provide structural stability, then the wall achieves sufficient strength and stability, but the material cost increases and the visual appearance becomes unattractive
Solution Approach 1:
The patent replaces solid steel posts with wire mesh posts that have a porous, open structure. The wire mesh provides structural stability through its geometric configuration rather than material density, achieving the required strength while using significantly less material and reducing cost.
Solution Approach 2:
The patent combines wire mesh panels with wire mesh posts to create a composite structural system. This composite approach distributes structural loads across the entire wall assembly rather than relying on massive individual posts, achieving sufficient strength with lighter, more economical materials.
2Stability of the object's composition
If solid steel posts with closed side surfaces are used, then structural stability is improved, but the visual appearance becomes striking and unattractive compared to wire mesh panels
Solution Approach 1:
The wire mesh posts maintain structural stability through their open porous structure rather than closed solid surfaces. This allows the posts to be visually integrated with the wire mesh panels, creating a uniform appearance while still providing the necessary structural support.
3Device complexity
If a fixed connection type using bores and screws is used, then the wall assembly is simplified, but the adaptability for on-site adjustments is lost
Solution Approach 1:
The patent employs a dynamic connection system where panels can be attached to and detached from posts through simple mechanical means. This allows the wall configuration to be easily adjusted on-site by repositioning panels along the posts without requiring complex drilling or fastening operations.
4Quantity of substance
If narrow walls with large static slenderness ratio are constructed, then material usage is reduced, but the resistance to horizontal deflection becomes insufficient
Solution Approach 1:
The patent utilizes the inherent flexibility of the wire mesh structure to accommodate horizontal deflections rather than resisting them rigidly. The mesh configuration allows controlled movement that maintains structural integrity while reducing material requirements compared to rigid solid constructions.

AI summary
The unit has two metal sheets (2) forming longitudinal sides and arranged at a distance from one another. One of the sheets forms a base of a wall filling cage of the unit, which is impermeable for a filling material (32). The unit is partially filled with the material in a transport condition or delivery condition. The unit borders the cage with a wall filling space (31) for the filling material. The metal sheets and/or posts and/or metal posts and/or a reinforcement component and/or a screw clamping-fastening unit and/or a metal sheet spacer are made of iron, steel and stainless steel.
