Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional profiles with through holes and threaded rods are used, then electrical connections can be established, but professional installation knowledge is required and extensive work is needed to hide current sources and wires
Solution Approach 1:
The profile is segmented into two separate longitudinal openings: one for mechanical support (receiving support elements with cables) and one for electrical connections (receiving electrical conductors). This segmentation allows independent installation of mechanical and electrical components, enabling non-electricians to perform mechanical assembly while electricians handle electrical connections separately, thus improving installation ease without compromising electrical connection reliability
Solution Approach 2:
The profile acts as an intermediary structure that separates and organizes mechanical support functions and electrical connection functions into distinct spatial zones. The first longitudinal opening serves as an intermediary channel for mechanical components, while the second longitudinal opening serves as an intermediary channel for electrical conductors, allowing both functions to coexist without interference and simplifying the installation process
2Adaptability or versatility
If multiple sets of profiles are installed, then more electrical appliances can be supported, but the number of visible wires increases and each installation requires an electrician
Solution Approach 1:
By segmenting the profile into separate openings for mechanical and electrical functions, each additional set can be installed independently using the same modular approach. Non-electricians can replicate mechanical installations without increasing electrical complexity, allowing scalable deployment where only electrical conductors need to be managed by professionals, thus improving adaptability while controlling complexity
Solution Approach 2:
The profile design provides universal functionality for both mechanical support and electrical routing through its dual-opening structure. This multi-functional design allows the same profile type to be used across multiple installations with consistent installation procedures, enabling scalable deployment without proportionally increasing installation complexity
3Strength
If support elements are inserted through the longitudinal opening, then mechanical support is provided, but electrical short circuits may occur without proper insulation
Solution Approach 1:
The profile is divided into two separate longitudinal openings that physically separate mechanical support elements from electrical conductors. This spatial segmentation eliminates the risk of electrical short circuits by ensuring that conductive support elements cannot contact electrical conductors, while still providing adequate mechanical support strength through the dedicated first opening
Solution Approach 2:
The profile structure acts as an intermediary barrier between mechanical and electrical systems. The first longitudinal opening serves as an intermediary zone for mechanical components isolated from electrical conductors in the second opening, preventing harmful electrical interactions while maintaining mechanical support functionality

AI summary
The section has electrically conducting and longitudinal supply rails (19a, 19b) arranged in a cavity (4) on both sides of a longitudinal opening (3). The rails are electrically isolated from one another. Each rail has support faces (15a, 15b) that are parallel to a main face (2). Each edge of the opening has a ridge that is in direction of a base (13) of the cavity, where the ridge has height greater than thickness of rails. Support zones of a support element (5) are formed by an insulated electric element. An independent claim is also included for an installation comprising a fixation section.
