Solution Overview
Problem
Conventional fastening devices for lighting units on curved surfaces lack flexibility, stability, and ease of installation, making them difficult to produce and assemble, and often result in disruptive lighting effects due to cable shadow formation.
Innovation Solution
A fastening device with multiple fastening elements connected via flexible connections, allowing rotation and displacement, forming a U-shaped receiving channel that can be easily adapted to curved surfaces, and incorporating connecting webs for stability and ease of assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional continuous mounting devices are used, then stability is provided, but flexibility to adapt to curved surfaces is limited and device complexity increases
Solution Approach 1:
The mounting device is divided into multiple discrete mounting elements (first, second, third, fourth elements) that can be independently positioned and connected. Each element has mounting feet with adjustable positioning elements, allowing the device to conform to curved surfaces while maintaining structural integrity through modular assembly rather than requiring a complex continuous structure.
2Ease of operation
If conventional mounting devices are used, then stability is provided, but ease of manufacture and assembly deteriorates
Solution Approach 1:
The mounting device incorporates adjustable positioning elements (screws, bolts, or springs) that allow dynamic adjustment during assembly to accommodate variations in curved surface geometry. This dynamic adjustability simplifies the assembly process compared to rigid conventional devices, as installers can easily adapt each mounting element to the local surface curvature without requiring complex pre-engineered configurations.
3Object-generated harmful factors
If cables are routed through conventional mounting devices, then electrical connection is achieved, but harmful lighting effects (shadows) are generated
Solution Approach 1:
The cable routing function is extracted from the main mounting structure and implemented through separate cable guides or channels integrated into the mounting feet or connecting elements. This separation allows cables to be routed along the underside or external surfaces of the mounting device, removing them from the light path and eliminating shadow formation while maintaining electrical connection functionality without increasing overall device complexity.

AI summary
The invention relates to a fastening device (1) for fastening at least one luminaire unit (2) to a structural element (4), wherein the fastening device (1) has a plurality of fastening elements (10) which are arranged behind one another in a longitudinal direction and which each comprise a receiving region which is formed by a base portion (11) and two lateral portions (12), wherein the base portion (11) extends in a first transverse direction between the lateral portions (1)2 and connects the lateral portions (12), wherein the lateral portions (12) each extend away from the base portion (11) in a second transverse direction, wherein two fastening elements (10) which are adjacent in the longitudinal direction are connected to one another via a flexible connection which is designed to ensure a relative rotation of the adjacent fastening elements (10) with respect to one another about at least two, in particular about three, different axes of rotation which are perpendicular to one another. The flexible connection comprises two connecting webs (100) which extend in the longitudinal direction, wherein the two connecting webs (100) are each connected at a first connecting point to a first of the two adjacent fastening elements (10) and at a second connecting point to a second of the two adjacent fastening elements (10), wherein the first connecting points of the two connecting webs (100) are spaced apart from one another in the first transverse direction and wherein the second connecting points of the two connecting webs (100) are spaced apart from one another in the first transverse direction.
