Fencing Panel Interlocking Bends for Fast, Water-Resistant Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fencing panels require additional connecting elements like rivets, screws, or welds for assembly, which complicates the process and may compromise water tightness.
Innovation Solution
A fencing panel design featuring detachable sections with intermeshing bends and a filling material, such as expanded polystyrene, that forms a closed profile without the need for additional fasteners, ensuring easy assembly and improved water resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If additional connecting elements like rivets, screws, or welds are used to connect panel sections, then the structural strength is improved, but the assembly complexity and time increase
Solution Approach 1:
The panel is divided into separate front and rear sections that can be assembled together through intermeshing bends, allowing each section to be manufactured independently and then connected through a simple interlocking mechanism rather than requiring multiple fasteners
Solution Approach 2:
The connecting elements are integrated directly into the panel sections themselves through the intermeshing bends, eliminating the need for separate rivets, screws, or welds. The bends themselves serve as the connection mechanism, merging the fastening function into the structural components
2Strength
If additional connecting elements are used to connect panel sections, then the structural strength is improved, but the water tightness may be compromised
Solution Approach 1:
The intermeshing bends create a nested interlocking structure where the front section bends insert into corresponding slots in the rear section, forming a tight nested connection that eliminates gaps and ensures water tightness without requiring additional fasteners that could compromise sealing
3Stability of the object's composition
If thicker material is used to ensure rigidity, then the structural rigidity is improved, but the weight increases
Solution Approach 1:
The panel sections incorporate curved bends and arches rather than straight rigid elements. These curved geometries provide structural rigidity through their shape rather than requiring thicker material, allowing the use of thinner 0.5mm steel sheets that are still sufficiently rigid when properly configured
Solution Approach 2:
The panel uses a composite construction with thin steel sheets reinforced by the intermeshing bend structure and filled with lightweight material (such as expanded polystyrene) in the cavity, creating a rigid yet lightweight composite structure that outperforms solid thicker material in strength-to-weight ratio
