Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing device carriers for attaching electrical devices to building walls are cumbersome, time-consuming to install, and difficult to adapt to varying wall thicknesses and cable routing requirements, often leading to cable interference and damage.
Innovation Solution
A device carrier with a base element and a protruding carrier element that allows for adjustable length, a hollow design for cable routing, and a clamping mechanism for easy device holder attachment, featuring insertion elements and a deflection surface to guide cables efficiently and prevent interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cables are routed outside the beam in existing device carriers, then cable routing is possible, but the cable is exposed to damage and material must be routed around the beam and cable
Solution Approach 1:
The patent implements cable routing by nesting the cable path within the beam structure. The beam contains internal channels or cavities that guide cables from the wall construction through the insulation material directly to the device holder, eliminating the need for external cable routing and protecting cables from damage.
Solution Approach 2:
The patent introduces an intermediary cable guide structure within the beam that mediates between the wall construction and the device holder. This intermediary element provides a protected pathway for cables, allowing them to pass through the insulation material without being exposed to the exterior environment.
2Adaptability or versatility
If the distance between base plate and device holder is fixed in existing carriers, then manufacturing is simplified, but adaptation to varying wall material thickness is not possible
Solution Approach 1:
The patent implements an adjustable carrier element that can vary in length or position. The carrier element connecting the base plate to the device holder is designed with telescopic sections, sliding mechanisms, or interchangeable segments that allow the distance between the base plate and device holder to be adapted to different wall material thicknesses while maintaining structural integrity.
Solution Approach 2:
The patent divides the carrier element into multiple segments or modular sections that can be assembled in different configurations. This segmentation allows the overall length of the carrier element to be adjusted by adding or removing segments, enabling adaptation to varying wall thicknesses while using standardized manufactured components.
3Ease of operation
If multiple cables are inserted into existing sockets, then cable connectivity is achieved, but cables meet at one point and can block one another
Solution Approach 1:
The patent transitions from a single-point cable convergence to a distributed cable management system using multiple insertion elements arranged in different spatial dimensions. Cables are routed through separate insertion channels or ports on the carrier element, distributing them across different locations and orientations, which prevents cables from blocking each other while maintaining ease of insertion.

AI summary
The holder (3) has a base element (1) fastening within a building wall, where the holder is accessed from an outer side of the wall. A fastening surface is provided on the holder or an elongated supporting element (2) i.e. flat supporting plate, to fasten the holder to the element. The surface is extended or elastically formed parallel to a circumference surface (4) of the element such that the fastening surface is deflected perpendicular to the circumference surface. A cylindrical clamping piece engages on the fastening surface and forms a retain connection between the element and the holder. USE : Device holder for fastening an electrical device e.g. switch box and light switch, to a building wall. Uses include but are not limited to exterior wall, interior wall, room wall or ceiling or floor surfaces. ADVANTAGE : The holder enables simple electrification of the building wall and allows the quick and easy installation of the electrical device on the different building walls in a simple manner. The holder has simple construction, and enables reliable support for the electrical device.
