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 assemble fencing panels, then the structural strength is improved, but the assembly process becomes more complex and water tightness is compromised
Solution Approach 1:
The patent merges the connecting elements directly into the panel sections by forming intermeshing bends as integral parts of the aluminum sections. The front section includes an additional arm with double bend, and the rear section includes an arm with oblique bend, which intermesh to form a locked connection without requiring separate fasteners. This integration eliminates the need for additional connecting elements while maintaining structural strength.
Solution Approach 2:
The patent applies the nesting principle by having the arm of the rear section inserted within and locked by the additional arm structure of the front section. The intermeshing bends create a nested configuration where one section's structural element fits within another, forming a unified closed profile that provides both strength and simplicity.
2Strength
If additional connecting elements like rivets, screws, or welds are used to assemble fencing panels, then the structural strength is improved, but water tightness deteriorates due to penetration holes
Solution Approach 1:
By merging the connecting functionality into the panel's structural bends themselves, the invention eliminates penetration holes that would compromise water tightness. The intermeshing bends form a continuous closed profile that prevents water infiltration while providing the necessary structural connection between sections.
3Stability of the object's composition
If thicker raw material (0.7 mm) is used to ensure rigidity, then the structural rigidity is improved, but the weight increases
Solution Approach 1:
The patent segments the panel into front and rear sections with specific geometric configurations. The front section includes an additional arm with double bend, and the rear section includes an arm with oblique bend. This segmentation creates a structurally optimized design where thin-walled sections (0.5 mm) achieve the required rigidity through their geometric form and interlocking configuration rather than relying on material thickness.
Solution Approach 2:
The patent uses composite construction by combining thin aluminum sheets (0.5 mm) with a filling material inserted into the closed profile. This composite structure provides enhanced rigidity and reinforcement while maintaining light weight, as the filling material contributes to structural stiffness without adding significant mass.
