Drywall Cable Installation Fixing Element
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for installing electrical connections in drywall are cumbersome due to the difficulty in accurately locating and marking cable positions, often resulting in slipped cables, unnecessary holes, and damage to the drywall, especially in thicker or multi-layered structures.
Innovation Solution
A method where a fixing element is anchored to the first component's exterior, allowing for a marking opening to be created from the first component through the interior space to the second component, enabling precise marking and drilling of installation points without invasive measurements or damage, using a fixing element with an anchoring and fixing section to secure cables and facilitate accurate hole creation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a positioning device is attached to the inside of the first component using adhesive, then the connection cable position can be marked, but the adhesive does not hold reliably due to dirt particles and rough surface
Solution Approach 1:
The positioning device is divided into two separate components: an anchoring part that is introduced from the outside of the first component to provide stable anchoring, and a fixing part that is attached to the inside of the first component to hold the connection cable. This segmentation allows each part to perform its specific function optimally without the reliability issues of adhesive bonding to rough surfaces.
2Measurement precision
If a positioning device is screwed to the first component, then the cable position can be marked, but the screws may break out during piercing of the second component
Solution Approach 1:
The positioning device is divided into an anchoring part and a fixing part. The anchoring part is introduced from the outside and provides stable anchoring through anchoring elements that engage with the first component from the exterior side, preventing screw breakage during subsequent piercing operations on the second component.
3Measurement precision
If the first component is pierced to attach the positioning device, then the cable position can be marked, but extensive damage occurs on the outer surface of the first component
Solution Approach 1:
Instead of piercing the first component from the inside to attach the positioning device, the anchoring part is introduced from the outside of the first component. This inverted approach allows the anchoring elements to engage with the component exterior without creating damaging piercings through the outer surface, thus preserving the aesthetic appearance of the drywall.
4Measurement precision
If cable position is measured on the inside of the first component, then the installation point can be determined, but the cable may slip when cavity insulation is attached
Solution Approach 1:
The fixing part of the positioning device is attached to the inside of the first component before the cavity insulation is installed. This preliminary action secures the connection cable in its correct position using fixing elements that prevent slipping, ensuring that the cable remains stable throughout the subsequent insulation installation process.

AI summary
The invention relates to a method for creating an electrical installation in a wall (1), wherein a first component (2) is attached to a support structure (4), then initial installation steps are carried out, followed by the attachment of a second component (3), and finally the remaining installation steps are carried out. Before the second component (3) is attached, a fixing element (9) is anchored to the first component (2) at the installation point (7), to which connecting cables (6) are attached in an interior space (5) that is bounded only by the first component (2). From the interior space (5), a marking opening (8) is created in the second component at the location of the fixing element (9) in order to mark the installation point (7) on an exterior surface of the second component (3).After the second component (3) is attached, an installation opening (21) is created in the second component (3) at the installation point (7), through which the connecting cables (6) can be accessed and the electrical installation completed. To further develop the method in such a way as to simplify the installation of connecting cables (6) in drywall partitions (1), it is proposed that the fixing element (9) be anchored to the first component (2) in such a way that it is visible on an outer surface of the first component (2) facing away from the interior, and that the marking opening (20) in the second component (3) be created from the outer surface of the first component (2) through the interior (5). Furthermore, a fixing element (9) for carrying out the aforementioned method is proposed.
