Multilayer Insulated Panel With Orthogonal Fretted Sheets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing insulating multilayer panels face issues with inefficient sealing due to variable climate conditions, requiring additional sealing products and causing aesthetic and functional problems, and are difficult to install without risking safety, especially at altitude, due to geometric differences and potential deformations during transportation and installation.
Innovation Solution
A multilayer panel design featuring fretted sheets with orthogonal projections allows for efficient side and front connections without gaskets, enabling condensate drainage and allowing for installation with either surface facing outward, optimizing storage and transportation volumes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If gaskets are used to seal connections between panels, then sealing reliability is improved, but installation complexity and cost increase
Solution Approach 1:
The invention removes the gasket element from the connection system entirely. The fretted sheets are designed with interlocking profiles that create inherent mechanical interlocking between adjacent panels, eliminating the need for separate gasket components while maintaining sealing functionality through the geometric design of the frets themselves
Solution Approach 2:
The connection system is designed to be self-sealing through the geometric configuration of the fretted sheets. The interlocking fret profiles automatically create weather-tight joints when panels are assembled, requiring no additional sealing materials or complex installation procedures beyond basic panel placement
2Reliability
If panels are designed with asymmetric fret configurations, then connection reliability is improved, but installation difficulty increases due to orientation requirements
Solution Approach 1:
The invention employs asymmetric fret configurations on adjacent panels with complementary profiles. One panel features frets projecting in one direction while the adjacent panel has corresponding recesses, creating reliable mechanical interlocking. The asymmetry is resolved at the interface, allowing panels to be installed in either orientation while maintaining connection integrity
Solution Approach 2:
The invention allows panels to be installed with either face outward by designing the fret profiles to function correctly in reverse orientations. The interlocking mechanism works bidirectionally, so that regardless of which panel face is exposed, the connection between adjacent panels achieves the same sealing and mechanical properties
3Object-affected harmful factors
If additional sealing products are applied to connections, then infiltration resistance is improved, but installation time increases
Solution Approach 1:
The invention eliminates the need for additional sealing products by integrating the sealing function directly into the structural design of the fretted sheets. The interlocking fret profiles create inherent weather resistance, removing the separate step of applying sealing compounds and significantly reducing installation time
Solution Approach 2:
The connection system provides self-sealing through its geometric design. The fret profiles automatically create water and air tight joints through mechanical interlocking alone, requiring no time-consuming application of additional sealing materials while maintaining full infiltration resistance

AI summary
Insulated multilayer panel for realizing covers comprising a first and a second fretted sheet, a layer in insulating material interposed between said first and second sheet characterized in that said first fretted sheet projects with respect to the layer in insulating material in the direction orthogonal to the fret one for a width equal to the end rib, and said second fretted sheet projects with respect to the layer in insulating material in the same direction and opposite with respect to the projection of said first fretted sheet for a width equal to the end rib.
