Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If existing lighting devices are used for corner areas, then lighting function is provided, but installation complexity increases and assembly requires tools

Engineering Contradiction:

Improveease of installationVSAvoidinstallation complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The lighting device is divided into separate modular components: a lamp holder designed for corner mounting and a lamp cover that can be attached afterwards. This segmentation allows the lamp holder to be installed first in the corner area using simple fastening surfaces, then the lamp cover is attached separately using form-fitting latching elements, eliminating the need for complex tool-based assembly of the entire unit

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Instead of providing a pre-assembled lighting unit that requires complex tool-based installation, the invention inverts the approach by providing separately manufacturable lamp holder and lamp cover components that can be easily assembled on-site using simple form-fitting connections without tools

Inventive Principle:

Principle #13The other way round (Inversion)

2Volume of moving object

If lighting devices are designed for corner mounting, then space utilization improves, but adaptability to irregular angles decreases

Engineering Contradiction:

Improvespace utilizationVSAvoidadaptability to irregular angles

Core Design Contradiction:

Volume of moving objectVSAdaptability or versatility

Solution Approach 1:

The lamp holder is designed with flexible mounting capabilities that can adapt to different corner angles including irregular angles. The separate component design allows the lamp holder to be positioned and oriented to match the specific corner geometry, providing dynamic adaptability while maintaining space-saving corner mounting

Inventive Principle:

Principle #15Dynamics

3Ease of operation

If simple assembly is achieved through separate components, then ease of installation improves, but structural integrity may worsen

Engineering Contradiction:

Improveease of assemblyVSAvoidstructural integrity

Core Design Contradiction:

Ease of operationVSStrength

Solution Approach 1:

The lamp cover is designed with form-fitting latching elements that engage with corresponding features on the lamp holder, creating a secure mechanical connection. The curved or contoured geometry of the latching elements provides snap-fit engagement that ensures structural integrity while allowing tool-free assembly and disassembly

Inventive Principle:

Principle #14Spheroidality (Curvature)

AI summary

The invention relates to a lighting device for illuminating interior spaces in buildings or outdoor facilities. The lighting device can be designed as a linear luminaire, in which case it has a narrow, elongated shape. Such linear luminaires are, for example, in the form of neon lamps with tubular light sources or, more recently, with tubular LED light sources.
