Roofing Panel Interlock with Curvilinear Gutter for Moisture Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing insulated building panel interlock systems allow moisture, such as rain and condensation, to penetrate into the panel seam, compromising the integrity of the insulating core.
Innovation Solution
The design features a male and female connector configuration with bent surfaces, including a U-shaped male connector and a curvilinear female connector with a gutter portion and detent edge, which locks the panels together, forming a double gutter system to direct moisture away from the panel joint.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional male-female connector systems are used to join panels, then panel interlocking capability is achieved, but moisture penetration into the panel seam occurs
Solution Approach 1:
The connector system is divided into distinct functional zones: the male connector with U-shaped configuration for structural interlocking, and the female connector with curvilinear gutter portion for moisture management. This segmentation allows each component to specialize in its primary function while working together as an integrated system.
Solution Approach 2:
The curvilinear gutter portion acts as an intermediary element between the panel seam and the external environment. It intercepts moisture before it can reach the insulating core, channeling it away along the bent surface while allowing the detent edges to maintain the structural seal.
2Strength
If connectors extend outwardly from panel edges to enable interlocking, then panel coupling strength is improved, but vulnerability to moisture ingress increases
Solution Approach 1:
The female connector features a curvilinear gutter portion with continuous curved surfaces that naturally guide moisture away from the panel joint. The curved geometry provides smooth transitions that prevent moisture accumulation and facilitate drainage while maintaining the structural integrity of the connector.
3Reliability
If the female connector is bent back towards itself to form a nested position, then interlock fit is secured, but moisture drainage capability must be maintained
Solution Approach 1:
The male and female connectors are designed to nest within each other when joined, with the male connector fitting into the female connector's recessed area. This nested configuration provides a tight interlock fit while the outer curvilinear gutter portion remains exposed to perform its moisture drainage function.

AI summary
An insulated building panel includes a male connector configuration as well as a female connector configuration that are both formed of generally bent surfaces. The male connector as well as the female connector extends outwardly from the side faces of an insulating foam core so that the foam is protected from damage. The male connector is formed by bending the metal edge into a generally U shaped configuration with the outer edge of the U bent downwardly towards the interior of the panel. The female connector is bent back almost towards itself and terminates in a curvilinear gutter portion. The female portion includes a detent edge that defines a shallow receptacle into which a male detent edge is inserted so as to lock the male and female connectors in a nested position, thereby securing two panels together.
