Adjustable Fastening Element for Screed Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastening elements for wall, floor, or ceiling coverings require complex assembly procedures and cannot satisfactorily fix covering elements to a substructure without compromising the installation process, especially when screwing from the underside is necessary.
Innovation Solution
A fastening element with two movable sections that can adjust in length, allowing for flexible adaptation to different covering element dimensions, enabling secure mounting and easy assembly by allowing sections to be connected and adjusted relative to each other, with one section having a receptacle for the other and accessible for screwing from the top.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the fastening element is designed as a single piece with fixed sections, then the manufacturing is simple, but the adaptability to different covering element dimensions is poor
Solution Approach 1:
The fastening element is divided into multiple sections (first section, second section, third section) that can move relative to each other, allowing the overall length to be adjusted while maintaining a relatively simple molded construction for each section
Solution Approach 2:
The fastening element incorporates movable sections with holding forces that allow dynamic adjustment of the distance between attachment points, enabling adaptation to different covering element dimensions while maintaining structural integrity
2Ease of operation
If the projection is arranged to allow latching connection before placing on substructure, then the assembly sequence is simplified, but the ability to fix covering elements to fastening elements after installation is lost
Solution Approach 1:
The fastening element is segmented into multiple functional sections, with the first section providing latching capability and the second section providing attachment capability, allowing both operations to be performed in sequence without conflict
Solution Approach 2:
The fastening element utilizes the longitudinal dimension to separate the latching function (at one end) from the attachment function (at the other end), allowing both operations to occur at different positions and times without interfering with each other
3Manufacturing precision
If the sections are fixed at a predetermined distance, then the manufacturing precision is easy to maintain, but the flexibility to accommodate different covering element sizes is reduced
Solution Approach 1:
The distance between sections is made dynamically adjustable through movable connections with holding forces, allowing the fastening element to adapt to different covering element sizes while maintaining precise positioning when adjusted
Solution Approach 2:
The physical parameter of section distance is made variable rather than fixed, allowing adjustment to match different covering element dimensions while maintaining manufacturing simplicity through standardized section designs

AI summary
The invention relates to a fastening element (50; 50'; 50") for a laying system for creating a wall, floor or ceiling covering (110), wherein the fastening element (50; 50'; 50") can be attached between the wall, floor or ceiling covering (110) and a substructure (120), with at least two sections (2, 3), of which at least one section (2) has a receptacle (4; 4') designed to receive the other section (3) of a fastening element (50.1), wherein in the direction of the longitudinal extension of the fastening element (50; 50'; 50") the receptacle (4; 4') of one section (2) can be inserted into the other section (4; 4') of a fastening element (50.1).It is provided that the wall (50) of the receptacle (4; 4') facing the substructure (120) has a section (33) for fixing the fastening element (50;50'; 50") to the substructure (120) by means of at least one screw (21), nail or similar connecting means, which is accessible from the outside in the mounting position of the fastening element (50;50'; 50") on the substructure (120).
