Solution Overview

Problem

Existing safety barrier mesh panels for construction sites are heavy, costly, and difficult to handle, despite providing high safety, due to their weight and material density, which affects working conditions and production costs.

Innovation Solution

A mesh panel design featuring a framework with additional diagonal wires that angle relative to the main plane, reducing the number and thickness of wires required while maintaining strength, resulting in a lighter and more cost-effective solution.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If coarse wire dimensions and high mesh density are used to achieve high safety class, then strength is improved, but weight increases significantly

Engineering Contradiction:

Improvesafety classVSAvoidmesh panel weight

Core Design Contradiction:

StrengthVSWeight of moving object

Solution Approach 1:

The mesh panel is divided into multiple zones with different wire densities and thicknesses. The high-strength zone near the top uses coarser wires for safety compliance, while the lower extension zones use finer, lighter wires. This segmentation allows the panel to meet safety requirements with minimal overall weight.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different portions of the mesh panel have different wire dimensions and densities optimized for their specific functions. The top portion near the bend has higher strength requirements and uses coarser wires, while the extended lower portions use lighter wires since they require less strength.

Inventive Principle:

Principle #3Local quality

2Strength

If aluminum material is used to reduce weight and improve safety, then strength-to-weight ratio is improved, but production cost increases

Engineering Contradiction:

Improvestrength-to-weight ratioVSAvoidproduction cost

Core Design Contradiction:

StrengthVSEase of manufacture

Solution Approach 1:

The patent changes the material parameter from aluminum to steel, which has different strength and cost characteristics. By optimizing the wire dimensions and mesh density parameters, the steel mesh achieves comparable strength-to-weight ratio while significantly reducing production cost.

Inventive Principle:

Principle #35Parameter changes

3Strength

If high mesh density and coarse wire dimensions are used to ensure safety, then strength is improved, but handling difficulty increases

Engineering Contradiction:

Improvesafety classVSAvoidhandling ease

Core Design Contradiction:

StrengthVSEase of operation

Solution Approach 1:

The mesh panel is segmented into a main high-strength body and lighter extension portions. The extended lower zones use finer, more flexible wires that are easier to handle and install, while the upper portion maintains high strength for safety compliance.

Inventive Principle:

Principle #1Segmentation

4Reliability

If the mesh panel is designed with vertical extension and bent portions to achieve Z or C form, then safety functionality is improved, but structural complexity increases

Engineering Contradiction:

Improvesafety functionalityVSAvoidstructural complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The mesh panel is designed with flexible extension zones that can be bent and shaped into Z or C forms during installation to suit different safety requirements. The varying wire densities provide both flexibility for shaping and sufficient strength when formed, reducing the need for complex rigid structural designs.

Inventive Principle:
