Twist-Lock Wall Element Fixing for Fast Secure Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fixing devices for mounting wall elements are cumbersome and require manual or additional aid to secure wall elements before attaching closing profiles, especially when dealing with heavy or thick elements, and are not suitable for quick and flexible erection and dismantling.
Innovation Solution
A fixing device comprising a support profile, a securing element with an engagement element that twists onto the support profile, and a closing profile with a blocking element to prevent detachment, allowing easy attachment and release of wall elements without additional securing, and enabling quick erection and dismantling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wall elements are mounted using existing fixing devices with click connections or barbed connections, then the mounting process becomes cumbersome and difficult, but the wall elements can be securely held
Solution Approach 1:
The securing element incorporates a twistable connection mechanism that transitions from a loose initial state to a locked final state through rotational movement. The connection element can be twisted relative to the support profile, transforming the mounting process from static and cumbersome to dynamic and intuitive, while ensuring reliable fixation of heavy wall elements.
Solution Approach 2:
The invention replaces traditional click connections and barbed connections with a twistable mechanical coupling system. This substitution introduces a rotational degree of freedom that simplifies the mounting operation while maintaining or enhancing the security of wall element fixation through the twisting action that locks the connection.
2Productivity
If manual holding aids are used to secure wall elements during attachment, then the wall elements can be firmly held, but the mounting process becomes more complex and time-consuming
Solution Approach 1:
The securing element is designed to be self-positioning and self-locking through its twistable connection mechanism. The element automatically secures itself to the support profile through the twisting action, eliminating the need for external manual holding aids or complex positioning devices, thereby simplifying the mounting process and increasing productivity.
Solution Approach 2:
The mounting system is divided into modular components: the support profile, the twistable securing element, and the wall element itself. This segmentation allows each component to perform its specific function independently, with the securing element handling both the connection to the support profile and the retention of the wall element, reducing the need for additional auxiliary devices.
3Strength
If the securing element is made stiff enough to hold heavy wall elements, then the wall elements can be securely mounted, but the securing element becomes difficult to manipulate and install
Solution Approach 1:
The securing element utilizes dynamic twisting motion during installation to overcome its own stiffness. The twistable connection allows the installer to rotate the element into place, using the rotational action to overcome the mechanical resistance of the stiff material, after which the element locks into a rigid fixed position capable of supporting heavy wall elements.
Solution Approach 2:
The twistable connection mechanism introduces a curved or rotational degree of freedom to an otherwise rigid securing element. This curvature in the form of rotational movement allows the stiff element to be manipulated and installed more easily, while maintaining its high strength and holding capacity once installed.

AI summary
A fixing device for mounting wall elements for constructing a wall, includes: a support profile, A securing element which is designed to extend between the wall elements and can be twisted relative to the support profile between a first position in which an engagement element of the securing element remains separate from the support profile, and a second position in which the engagement element engages on the support profile for fixing and secures the wall elements; and a closing profile which in the second position is attachable to the securing element and comprises a blocking element for preventing the securing element from twisting back.
