Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastening systems for elongated profiles to walls require transverse wooden elements, which increase assembly width, are prone to moisture damage, and necessitate complete disassembly for replacement, leading to inefficiencies and potential structural issues.
Innovation Solution
A fastening assembly featuring a fastening element with a helical alignment mechanism that allows for flexible positioning and rotation, eliminating the need for transverse elements, and ensuring a secure, adjustable connection between the profile and the wall.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If transverse wooden elements are used to support elongated profiles, then the profiles can be fastened to the wall, but the assembly width increases and usable surface area is reduced
Solution Approach 1:
The invention extracts and eliminates the transverse wooden elements from the fastening system. Instead of using separate wooden laths or twill that extend transversally between profiles, the patent integrates the support function directly into the screw assembly through a helical alignment element that engages with the profile's opening, thereby removing the need for additional transverse components that consume surface area.
Solution Approach 2:
The invention merges the alignment and support functions into the screw assembly itself. The helical alignment element is integrated with the screw to form a unified fastening component that both secures the profile to the wall and provides the necessary alignment, eliminating the need for separate transverse wooden support elements.
2Reliability
If transverse wooden elements are used in the fastening assembly, then profiles can be aligned to the wall, but these elements are prone to moisture damage and reduced lifespan
Solution Approach 1:
The invention replaces the wooden transverse elements with a helical alignment element made of metal or durable material that is integrated into the screw assembly. This new component is designed to withstand environmental conditions including moisture, eliminating the lifespan and durability issues associated with wooden elements in outdoor applications.
Solution Approach 2:
The helical alignment element can be made from composite or engineered materials that combine the necessary mechanical properties with resistance to environmental factors such as moisture. This replaces the natural wood material that is susceptible to degradation in outdoor conditions.
3Manufacturing precision
If helical alignment element engages directly in profile opening, then alignment is achieved, but concentrated load may deform the opening
Solution Approach 1:
The invention segments the load path by introducing an intermediate engagement mechanism. The helical alignment element engages with the profile opening in a way that distributes the concentrated load across a larger area of the opening, preventing deformation while maintaining precise alignment capabilities.
4Reliability
If wooden transverse elements are used for fastening, then profiles can be secured to wall, but complete disassembly is required for replacement or maintenance
Solution Approach 1:
The invention segments the fastening system into independently replaceable components. The helical alignment element is designed to be accessible and replaceable without requiring disassembly of the entire wall covering system, allowing for localized maintenance and repair while maintaining fastening security.

AI summary
A fastening element, a fastening assembly and a method for fastening are described, such that the fastening element is configured so that it cooperates in such a way with an elongated element that it allows for a rotation of the fastening element about the central axis of the opening between a fastened state, in which a first angular position of the fastening element is transverse to the longitudinal axis of the elongated element and a removable state in which the second angular position is transverse to the longitudinal axis of the elongated element.
