Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the LED lighting module is made easily replaceable with tool-free attachment, then the ease of operation is improved, but the reliability of electrical connection may worsen
Solution Approach 1:
The lamp is divided into separable modules: the LED lighting module and the carrier element. The LED module can be independently removed and replaced without tools, while the carrier element remains fixed in the mounting rail. This segmentation enables easy replacement while maintaining reliable connections through the plug-in contacting element.
Solution Approach 2:
A contacting element with plug-in connection serves as an intermediary between the power supply conductors and the LED lighting module. This mediator ensures reliable electrical connection while allowing the LED module to be easily detached and reattached without exposing the conductors.
2Ease of manufacture
If the electrical conductors are made directly accessible for easy connection, then the ease of manufacture is improved, but the safety of the lamp worsens due to exposed wires
Solution Approach 1:
The contacting element with integrated socket acts as an intermediary that shields the electrical conductors. The conductors are connected to the socket behind the transparent diffuser, making them inaccessible while maintaining electrical connection functionality. This eliminates safety hazards while preserving ease of assembly.
Solution Approach 2:
The electrical conductors are nested within the carrier element structure, specifically connected to the contacting element behind the diffuser. This nesting conceals the conductors within the lamp housing, preventing exposure while maintaining connection accessibility during assembly.
3Adaptability or versatility
If the lamp design accommodates multiple orientation options for the LED module, then the adaptability is improved, but the device complexity worsens
Solution Approach 1:
The carrier element is designed with universal features: a U-shaped receiving area that can accommodate LED modules in multiple orientations (0° or 180° rotation). The contacting element with socket and the magnet holder provide multi-functional support for electrical connection and mechanical retention regardless of module orientation, enabling versatility without significant complexity increase.
4Object-affected harmful factors
If the current-carrying wires are positioned on the opposite side of the connecting leg for safety, then the safety is improved, but the ease of operation worsens due to reduced accessibility
Solution Approach 1:
The electrical connections are established in advance through the contacting element with integrated socket during manufacturing. The conductors are pre-connected to the socket behind the diffuser, eliminating the need for users to access or manipulate wires during operation or module replacement. This preliminary connection ensures safety while maintaining operational simplicity.

AI summary
The invention relates to a lighting device having a support element (2) with an elongated receiving region (3) which has a U-shaped cross-section and comprises a first limb (31) of the U, a second limb (32) of the U, and a connecting limb (33) that connects the two limbs (31, 32) of the U. The lighting device further has an LED lighting module (4) with at least one LED (5) for generating light in order to emit a light of the lighting device, said LED lighting module (4) being arranged on the support element (2) in a retained manner. The lighting device further has a contacting element (6) for supplying power to the LED lighting module (4). The connecting limb (33) has a through-opening, said contacting element (6) and LED lighting module (4) being arranged so as to be connected in an electrically conductive and reversibly releasable manner such that the electric connection passes through the through-opening. The design of the lighting device allows the conductive wires for supplying power to the LED lighting module (4) to be arranged on the connecting limb (33) side which lies opposite the at least one LED (5) of the lighting module (4). In this manner, access to the conductive wires is hindered and the lighting device is therefore particularly safe. Additionally, a particularly simple, safe, and reliable exchange of the LED lighting module (4) is made possible in this manner.
