Self-Locking Slat Assembly with Flexible Connecting Element
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing slat coverings that can be assembled edge-to-edge by self-locking interlocking are not practical for use on non-horizontal walls or ceilings, as they require nailing, screwing, or stapling, which limits their application to fixed-lay coverings and does not allow for floating-lay installations, and existing solutions for wall or ceiling coverings are not suitable for self-locking interlocking slats.
Innovation Solution
A method and assembly system using flexible or malleable connecting elements with a locking lug and rear lip that can be elastically deformed to clamp and secure slats edge-to-edge, allowing for both fixed and floating installations on any type of wall or ceiling, including non-horizontal surfaces, by utilizing a connecting element with a first part that forms part of the clamping mechanism and a second part attached to a rigid support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If self-locking interlocking slats are used for wall or ceiling coverings, then edge-to-edge assembly is enabled, but traditional nailing/screwing methods are required which limit floating-lay installations
Solution Approach 1:
A connecting element acts as an intermediary component between the slat and the wall/ceiling. This connecting element includes a first part that engages with the groove of the slat and a second part that attaches to the support structure, eliminating the need for direct nailing or screwing of the slat itself and enabling both fixed and floating installation methods
2Adaptability or versatility
If connecting elements are added to enable flexible wall/ceiling installation, then installation versatility is improved, but device complexity increases
Solution Approach 1:
The connecting element is designed with multi-functionality to reduce overall system complexity. The first part of the connecting element engages with the groove of the slat, while the second part attaches to the wall or ceiling support structure. This single component performs multiple functions: securing the slat, enabling both fixed and floating installations, and eliminating the need for separate fastening hardware
3Adaptability or versatility
If rear lip of slat groove is extended to allow wall attachment, then wall covering capability is enabled, but slat profile complexity increases
Solution Approach 1:
The system is segmented into distinct functional components: the slat with its groove and tongue for edge-to-edge interlocking, and a separate connecting element with two parts for wall attachment. This segmentation allows the slat profile to remain simple and optimized for interlocking, while the connecting element handles the wall attachment function
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
Enables the secure and flexible installation of self-locking slats on any wall or ceiling, including non-horizontal surfaces, allowing for both fixed and floating lay options, thereby expanding the application of edge-to-edge interlocking slats beyond traditional floor coverings.
Implementation Method 1
the rear lip of said groove being elastically deformed so as to allow said tongue to be fitted into said groove
Implementation Method 2
These mechanical locking means most often comprise a locking lug projecting from the tongue and a recess made in the lower lip of the groove and capable of receiving said locking lug

AI summary
The invention relates to an assembly which includes two facing strips (1) which can be assembled edge-to-edge by self-locking socketing, and at least one linking element (2). Said linking element (2) comprises a first portion (20) suitable for being positioned in the groove (120) of a strip, and in contact with the inner surface (122a) of the rear lip (122). Once said first portion (20) has been positioned in the corresponding groove (120) of a strip, the two strips can further be coupled together, the first portion (20) of the linking element being clamped between the rear lip (122) and the tab (130) inserted in the groove, at least in one area for contact or near-contact (Z1) between the tab (130) and the rear lip (122) of the groove (120).
