Concealed Fastening Longitudinal Beam Profile for Roofing

Solution Overview

Problem

Existing roofing device mounting systems for ceiling connections, such as roof overhangs, face challenges with visible fasteners and require additional adapter elements, which compromise aesthetics and installation complexity.

Innovation Solution

A longitudinal beam profile with a mounting side featuring an undercut area for the fastening means, allowing the profile to overlap and conceal the assembly means, enabling invisible fastening and smooth, aesthetic surfaces, along with a method for installing the profile that includes drilling and positioning to ensure the fastening means are hidden from view.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If fasteners are used to attach the longitudinal beam profile to the ceiling connection, then the mounting strength is improved, but the aesthetic appearance deteriorates due to visible fasteners

Engineering Contradiction:
Core Design Contradiction:
StrengthVSShape

Solution Approach 1:

The fastening function is extracted from the visible surface and relocated to an undercut area. The mounting means are positioned in a recessed zone that is overlapped by the beam profile, separating the fastening function from the visible aesthetic surface while maintaining structural integrity.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The fastening system is moved from the two-dimensional visible surface to a three-dimensional undercut area. By utilizing the depth dimension and positioning fasteners in a recessed zone that is overlapped by the beam profile, the solution achieves both strong mounting and clean aesthetic appearance.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Adaptability or versatility

If angle brackets are used as adapters to attach the beam profile to the ceiling connection, then the mounting versatility is improved, but the device complexity increases due to additional adapter elements

Engineering Contradiction:
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The mounting function and the beam profile structure are merged into a single integrated design. The longitudinal beam profile includes built-in mounting means positioned in an undercut area, eliminating the need for separate angle bracket adapters and reducing overall system complexity while maintaining mounting versatility.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The longitudinal beam profile is designed with multi-functionality, serving both as the structural beam and as the mounting element. The integrated mounting means provide universal attachment capability directly to the ceiling connection without requiring additional adapter components.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Ease of operation

If the mounting side is positioned at the visible surface, then the ease of operation is improved, but the aesthetic appearance deteriorates due to visible mounting means

Engineering Contradiction:
Core Design Contradiction:
Ease of operationVSShape

Solution Approach 1:

The beam profile is segmented into distinct functional zones: a mounting side with mounting means positioned in an undercut area for easy installation, and a visible side with a smooth aesthetic surface. This segmentation allows each side to fulfill its specific function without compromise.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different regions of the beam profile are assigned different qualities: the mounting side features an undercut area with mounting means optimized for installation accessibility, while the visible side provides a smooth aesthetic surface. Each local region is optimized for its specific function.

Inventive Principle:
Principle #3Local quality
