Elastomeric Interlocking Edges for Flat Roof Panel Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing insulating metal panels with interlocking systems are not suitable for flat roofs due to infiltration issues when the slope is minimal, as they rely on substantial slopes for effective sealing.
Innovation Solution
A panel structure with elastically deformable coupling edges that form inner chambers upon engagement, along with wind-barrier clips and fastening brackets, ensuring a secure seal and easy installation on flat roofs by allowing panels to be slid into place without tilting, and accommodating various accessories.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional interlocking metal panels are used, then the panels can be securely coupled together, but water infiltration occurs on flat roofs with minimal slope
Solution Approach 1:
The patent introduces a vertical dimension to the sealing mechanism by creating an overlapping configuration where one panel extends vertically over the adjacent panel. This vertical overlap, combined with the horizontal interlocking, creates a multi-dimensional barrier that prevents water infiltration even on flat surfaces where traditional single-plane interlocking fails.
Solution Approach 2:
The patent combines metal panels with elastomeric sealing materials to create a composite panel structure. The elastomeric material provides flexible sealing capabilities that adapt to minimal slopes, while the metal panels provide structural integrity. This composite approach resolves the contradiction by integrating materials with complementary properties.
2Reliability
If panels are designed for steep slope roofs, then effective sealing is achieved, but installation becomes difficult on flat roofs requiring substantial tilting
Solution Approach 1:
The patent incorporates elastomeric materials that provide dynamic sealing capabilities, allowing the panel configuration to adapt to different roof slopes. The flexible nature of the elastomeric components enables effective sealing on flat roofs without requiring the rigid tilting needed for traditional metal panels, thus maintaining ease of installation while ensuring sealing effectiveness.
3Ease of manufacture
If traditional coupling systems are used, then panels can be fastened together, but the system does not accommodate accessories securely
Solution Approach 1:
The patent designs the panel coupling system to serve multiple functions: it provides structural connection between panels, creates water-tight sealing, and incorporates integrated attachment points for accessories. The elastomeric components and overlapping configuration are designed to universally accommodate various accessory types, making the system versatile while maintaining ease of assembly.
4Strength
If rigid interlocking panels are used, then structural strength is maintained, but flexibility for sealing on minimal slopes is lost
Solution Approach 1:
The patent creates a composite structure combining rigid metal panels for structural strength with flexible elastomeric materials for sealing adaptability. The metal components maintain structural integrity while the elastomeric portions provide the necessary flexibility to seal effectively on minimal slopes, resolving the contradiction between strength and adaptability.

AI summary
A panel structure, particularly for roofs of buildings, characterized in that it comprises a sheet associated with an insulating body and equipped, on two opposite sides, with a first coupling edge and a second coupling edge; the coupling edges are elastically deformable so that when one structure is caused to slide towards an analogous structure, the edges mutually engage, defining an interlocking area in which the coupling edges form a plurality of inner chambers.
