Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastening devices for lamps are complex to assemble and require precise fitting, making pre-assembly and replacement difficult, especially in cramped spaces, and often result in lateral glare due to unaligned light beams.
Innovation Solution
A modular fastening device with insert elements and a diffuser that can be easily snapped into place, featuring compression springs to compensate for thermal expansion and adjustable shielding bodies to align light beams, preventing lateral glare and allowing for time-saving assembly and replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If individual light sources are connected directly to the reflector, then the lighting device can be assembled, but the assembly work is extremely time-consuming and requires specialist knowledge
Solution Approach 1:
The device is divided into modular components: a support body with integrated diffusers and insert elements that can be pre-assembled as a complete lighting unit. This modular segmentation allows the entire lighting assembly to be installed as one unit rather than connecting individual light sources, dramatically reducing installation time and complexity while maintaining the ability to replace the entire module easily.
2Ease of operation
If the supporting body is already attached to ceilings or walls, then installation is complete, but subsequent attachment of lamps is difficult due to cramped spatial situations
Solution Approach 1:
The lighting components are nested within the support body structure. The diffusers are positioned within the U-shaped support body, and the insert elements with light sources are nested within the diffusers. This nested configuration allows the entire lighting assembly to be compact and easy to attach to the support body from below, even when the support body is already mounted in hard-to-reach ceiling or wall locations.
3Object-affected harmful factors
If light waves radiate into areas outside the desired alignment, then the beam path is wide, but lateral glare occurs near the supporting body
Solution Approach 1:
Insert elements are introduced as intermediary components between the light sources and the diffusers. These insert elements act as mediators that shape and control the beam path of light waves, directing them through the diffuser while preventing lateral radiation. This intermediary structure effectively blocks harmful lateral glare while maintaining proper illumination distribution through the diffuser.
Solution Approach 2:
The insert elements provide localized beam path control at specific positions within the lighting assembly. Each insert element is positioned to control the light from its associated light source, creating localized beam shaping that prevents lateral glare in specific areas while maintaining overall illumination quality. This local quality control allows precise management of light distribution patterns.
4Ease of repair
If each individual light source has to be connected to the reflector, then the lighting device can function, but replacement work is difficult and requires specialist knowledge
Solution Approach 1:
The lighting system is segmented into a replaceable module consisting of the support body, diffusers, and insert elements assembled together. This segmentation allows the entire lighting assembly to be removed and replaced as one unit, making maintenance and light source replacement simple tasks that do not require specialist knowledge of electrical connections or complex disassembly procedures.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables efficient, aesthetically pleasing, and homogeneous illumination by preventing lateral glare and simplifying the assembly and replacement of multiple light sources on a supporting body, while accommodating thermal changes and various installation geometries.
Implementation Method 1
at least one compression spring (12) is formed or provided on each side of the insert elements (11), which in the unloaded state protrudes beyond the free end face (13) of the insert elements (11)... due to their compensating movements, the longitudinal expansion of the insert elements can be compensated
Implementation Method 2
a diffuser (8) is arranged on this side of the connecting leg (7), which accordingly is positioned in the beam path of the optical elements (2)... the respective insert element (11) is held centered by the diffuser (8)

AI summary
In a mounting device (1) for light sources (2), consisting of: - a support body (3) that is attached to or in a ceiling, a wall or a floor, - a plurality of light sources (2) in the form of individual LEDs and/or in the form of a flat circuit board (2') with a plurality of light sources (2) secured to the support body (3), - electrical conductors (5) that are connected to the respective light source (2) and an electrical power source (6), - and a cap-like diffuser (8) that covers the light sources (2) or the circuit board (2'), a plurality of light sources (2) should be able to be pre-assembled in order to attach them to a reflector (16) or the support body (3) in a time-saving and uncomplicated manner. This is achieved by providing an insert element (11) in the respective beam path (20) of the light source (2), which is held centered by the diffuser (8).
