Folding Protection Shield with Pivoting Net Struts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing barrier signs require complex and voluminous folding of net struts for transport, leading to increased volume and difficulty in handling and assembly, with existing solutions either deforming the net or requiring separate transportation of components.
Innovation Solution
Rigidly connecting pairs of net struts to framework elements, allowing them to pivot relative to each other, and using bolt connections for easy assembly and disassembly, with a V-shaped or star-shaped arrangement for enhanced stability and reduced transport volume.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If net struts are folded into transport position aligned parallel to the pull rod, then the construction becomes compact for transport, but the net becomes bunched up around them increasing the volume to be transported
Solution Approach 1:
The barrier shield is divided into separate modular components: the scaffolding framework (net struts and framework elements) and the net are transported separately. This segmentation allows the scaffolding to be folded compactly without the net being deformed or bunched up, eliminating the volume increase problem while simplifying on-site assembly where the net is simply attached to the erected framework
2Ease of operation
If net struts are rigidly connected to framework elements with pivoting capability, then assembly is simplified, but the attachment mass must be increased for stability
Solution Approach 1:
Pairs of net struts are rigidly connected to form framework elements, merging multiple components into unified structural units. This combination provides stable attachment points that can support the net without requiring excessive mass, while the pivoting connection between framework elements enables simple assembly operations
3Ease of operation
If net is attached after scaffolding erection, then handling is easier, but the net must be transported separately increasing complexity
Solution Approach 1:
The system is segmented into the scaffolding framework and the net as separate transportable components. The framework can be folded compactly for transport and erected first at the site, while the net is transported separately and attached afterward, combining the benefits of easy handling during transport with simplified on-site assembly operations
