Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing grid structure fabrication techniques for security barriers are labor-intensive, time-consuming, and expensive due to the extensive use of welding, which hinders efficient manufacturing and increased security requirements.
Innovation Solution
A security grid structure composed of elongate channel sections with apertures and tubular elongate members, where elongate elements are secured using puddle-welding, and filled with ultrahard materials like ceramic briquettes for enhanced deterrent effect, reducing the number of welds required and incorporating attack-resistant features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional welding fabrication technique is used to create grid structure, then security level and structural rigidity are achieved, but manufacturing time, labor cost, and fabrication complexity increase significantly
Solution Approach 1:
The grid structure is divided into modular components: channel sections with pre-formed apertures, elongate members, and elongate elements. These segments can be manufactured separately and assembled through the apertures using minimal welding, thereby maintaining structural integrity while significantly reducing fabrication time and labor requirements.
Solution Approach 2:
Apertures are pre-formed in the channel sections during manufacturing, and elongate members are pre-positioned through these apertures before final assembly. This preliminary preparation eliminates the need for extensive on-site welding and complex fabrication procedures, improving manufacturing efficiency while preserving security performance.
2Stability of the object's composition
If extensive welding is used to assemble grid components, then structural rigidity and security are achieved, but fabrication time and labor intensity increase
Solution Approach 1:
The structure is segmented into channel sections, elongate members, and elongate elements that can be assembled through pre-formed apertures with minimal welding required at connection points, reducing fabrication time while maintaining structural rigidity through the distributed aperture arrangement.
Solution Approach 2:
The apertures in the channel sections serve as intermediaries that guide and position the elongate members during assembly. This intermediary feature enables precise component alignment and reduces the need for extensive welding by providing predetermined connection pathways.
3Reliability
If traditional mesh panels are used for security barriers, then basic security level is achieved, but enhanced security requirements cannot be met
Solution Approach 1:
The grid structure combines different material types and structural forms: channel sections (structural framework), elongate members (cross-bracing elements), and elongate elements (additional reinforcement). This composite construction achieves enhanced security performance beyond traditional mesh panels while maintaining manageable structural complexity through modular design.
