Profiled Metal Sheet Interlocking Beads Conceal Fixings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing profiled metal sheets used in building construction require seam fixings that detract from the aesthetic appearance of the facade, necessitating a solution to conceal or eliminate these fixings without compromising structural integrity.
Innovation Solution
A profiled metal sheet design featuring a folded end forming a box with beads on its vertical walls and a ribbed end with matching beads, allowing interlocking for secure attachment without visible fixings, while maintaining elasticity for assembly and concealment of screws.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional profiled metal sheets are used with seam fixings, then structural integrity is ensured, but aesthetic appearance deteriorates due to visible fixings
Solution Approach 1:
The invention extracts and removes the traditional seam fixings from the visible surface of the metal sheet. By integrating the fixing mechanism into the folded end structure itself, the harmful visual element (visible screws or clips) is eliminated while the structural function is preserved through the interlocking beads and ribs.
Solution Approach 2:
The fixing mechanism is nested within the folded end structure of the metal sheet. The beads are formed within the folded end, and the rib structure contains the interlocking elements, creating a nested arrangement where the fixing function is hidden within the overall sheet structure rather than being externally attached.
2Shape
If seam fixings are removed to improve aesthetics, then aesthetic appearance improves, but ease of manufacture deteriorates due to complex folded end structures
Solution Approach 1:
The folded end structure with beads is pre-formed during the metal sheet manufacturing process itself, rather than being added as a separate component. The rib is also formed as an integral part of the sheet. This preliminary action during manufacturing eliminates the need for separate assembly steps, maintaining ease of manufacture despite the increased structural complexity.
Solution Approach 2:
The invention merges the aesthetic covering function with the structural fixing function into a single integrated component. The folded end structure serves both as the visible aesthetic element and as the housing for the fixing mechanism, while the rib combines structural support with the interlocking fixing feature, reducing the total number of components and assembly steps.
3Shape
If folded end structures with ribs and beads are used to eliminate visible fixings, then aesthetic appearance improves by concealing fixings, but device complexity increases
Solution Approach 1:
The folded end structure is segmented into distinct functional zones: the box-shaped enclosure, the beads for interlocking, and the rib with its own beads. This segmentation allows each element to perform its specific function efficiently while maintaining overall simplicity. The modular nature of these segments makes the complex appearance manageable and manufacturable.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The interlocking design enables secure attachment of metal sheets without visible fixings, maintaining aesthetic appeal while ensuring structural integrity and allowing for various assembly configurations and materials, including steel, stainless steel, aluminum, and organic coatings.
Implementation Method 1
said box comprising a first bead on each of its vertical walls and a second end provided with a rib (5; 15) comprising a second bead on each of its walls, said second beads being arranged substantially at the same height as said first beads and separated by a distance substantially equal to that separating said first beads, said rib having a shape allowing its interlocking on said box and said first and second beads having shapes allowing their respective clipping
Implementation Method 2
maintaining elasticity for assembly and concealment of screws

AI summary
The sheet (1) has an end folded towards an interior of the sheet to form a caisson (2) formed by horizontal and vertical walls, where the sheet is made of steel. The caisson has flanges (3, 4) on the vertical walls, and another end has a rib (5) with flanges (6, 7) that are placed on the vertical walls and placed at a height same as that of the flanges (3, 4). The flanges (5, 6) are separated from a distance equal to a distance separating the flanges (3, 4). The rib has a shape to stack the rib on the caisson, and the flanges (3, 4, 6, 7) have shapes for respective clipping of the flanges. An independent claim is also included for a metal wall comprising profiled metal sheets.
