Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing barriers are either too heavy or fail to achieve the desired minimum strength or stiffness, making them inadequate for edge protection.
Innovation Solution
A barrier design featuring a combination of first and second wires made of steel, where the second wires are strategically coupled to the transverse and vertical portions of the first wires, optimizing the geometric ratios to enhance strength and stiffness while reducing weight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional steel mesh barriers are used, then strength and stiffness are achieved, but weight is excessive
Solution Approach 1:
The barrier is segmented into discrete wire components arranged in a specific geometric pattern, replacing traditional solid mesh panels. This segmentation allows for optimized load distribution while reducing material usage and overall weight.
Solution Approach 2:
The barrier employs a composite wire structure combining vertical and transverse wire elements with specific geometric relationships. This composite arrangement creates a lightweight yet strong structure that achieves required strength without excessive weight.
2Weight of stationary object
If barrier weight is reduced, then ease of installation improves, but strength and stiffness may be compromised
Solution Approach 1:
The invention optimizes geometric parameters including wire diameters, spacing distances (D1, D2, D3, D4), and angular relationships to achieve the lightest possible structure that still meets strength requirements. Specific ratios like D1:D3 < 1:2 and D1:D4 between 1:4.5 and 1:3.9 are established through parameter optimization.
Solution Approach 2:
The barrier design incorporates three-dimensional spatial arrangement of wires with specific orientations in vertical, transverse, and horizontal directions. This dimensional optimization allows the structure to achieve high strength-to-weight ratio by distributing loads across multiple spatial dimensions.
3Strength
If geometric complexity is increased to improve strength, then manufacturing precision requirements increase
Solution Approach 1:
The design provides specific geometric guidance (such as D1:D3 ratio less than 1:2) that offers sufficient precision to ensure strength while avoiding overly stringent requirements. This partial specification approach achieves the necessary strength without demanding excessive manufacturing precision.

AI summary
A barrier that includes a plurality of first wires that each have a vertical portion that extends in a vertical direction and a transverse portion that extends within sixty degrees of a transverse direction is provided. The transverse portions of each of the plurality of first wires can collectively define a midline that extends in a horizontal direction and can substantially bisect the transverse portions of each of the plurality of first wires. The midline can define a proximal portion for each of the transverse portions and a distal portion for each of the transverse portions. The barrier can include a plurality of second wires that each extend in the horizontal direction. At least one of the plurality of second wires can be coupled to the proximal portions of each of the transverse portions of each of the plurality of first wires.
