Device for fixing at least one object on a roof surface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for attaching objects to flat roofs involve drilling through the roof structure, which is invasive and unpredictable when the underlying structure is unknown, and lack flexibility and stability in object attachment and exchange.
Innovation Solution
A device comprising an anchoring plate with a base plate and cover layer, where the base plate is more stiff than the cover layer, is attached to the roof using bitumen, allowing secure and flexible attachment of objects without penetrating the roof, with adjustable connecting devices for different objects and conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If roof penetrations are used to attach objects to the roof surface, then the attachment stability is improved, but the structural effort and complexity increase due to drilling through the surface coverings and roof structure
Solution Approach 1:
The invention extracts the anchoring function from the roof structure itself by using a separate anchoring plate that distributes loads over a larger area of the roof covering, eliminating the need to drill into the roof structure while maintaining attachment stability
Solution Approach 2:
The anchoring plate acts as an intermediary element between the roof covering and the object to be attached. It distributes the attachment forces over a larger area of the roof covering, allowing stable attachment without penetrating the roof structure
2Reliability
If test drillings are carried out to determine the roof substructure, then the attachment reliability is improved, but the roof covering is damaged with boreholes
Solution Approach 1:
The invention extracts the need for test drillings by using an anchoring plate that does not require penetration into the roof structure. The plate can be positioned and attached without creating boreholes, eliminating the harmful effect while maintaining attachment reliability
Solution Approach 2:
Instead of drilling into the roof structure to ensure reliable attachment, the invention inverts the approach by using a plate that attaches to the roof covering surface and distributes loads, making test drillings unnecessary
3Adaptability or versatility
If multiple connecting devices are provided for flexible object attachment, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The anchoring plate is designed with multiple connecting devices that can accommodate different types of objects (photovoltaic systems, air conditioning units, etc.). The plate serves multiple functions: distributing loads, providing various attachment points, and supporting different connection methods, thereby achieving high adaptability without proportionally increasing complexity
