Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional fluorescent tubes are used, then the lighting apparatus provides standard illumination, but the apparatus suffers from color correction issues, flicker problems, and lack of control over brightness and light quality
Solution Approach 1:
The patent uses LED technology with DMX control capability to enable precise adjustment of brightness and color temperature parameters, eliminating the fixed characteristics of traditional fluorescent tubes and providing adaptable lighting control without flicker issues
Solution Approach 2:
The patent replaces the mechanical/electrical ballast system of fluorescent tubes with electronic LED drivers and DMX control systems, eliminating flicker problems inherent in traditional fluorescent ballast operation while providing digital control over lighting parameters
2Adaptability or versatility
If existing LED fixtures are used, then the lighting apparatus provides controlled illumination, but the apparatus becomes bulky and prone to overheating
Solution Approach 1:
The patent extracts the LED ribbon from a bulky fixture housing and mounts it directly to the fixture surface, removing unnecessary structural elements that trap heat and reduce airflow, thereby eliminating overheating while maintaining lighting control
Solution Approach 2:
The patent uses a thin, flexible diffuser material that allows heat to dissipate efficiently while providing the necessary light diffusion, replacing bulky opaque housings that trap heat around the LED components
3Adaptability or versatility
If existing LED fixtures are used, then the lighting apparatus provides controlled illumination, but the apparatus requires intrusive rigging hardware for installation
Solution Approach 1:
The patent designs the LED apparatus to visually replicate the appearance of traditional fluorescent tubes, allowing it to be installed in existing fluorescent fixtures without requiring additional rigging hardware or structural modifications
Solution Approach 2:
The patent creates a universal mounting system that works with both traditional fluorescent fixtures and modern LED fixtures, eliminating the need for specialized rigging hardware by making the apparatus compatible with existing infrastructure
4Weight of moving object
If LED ribbon is mounted directly without housing, then the apparatus becomes lightweight and easy to install, but the apparatus lacks protection and proper light diffusion
Solution Approach 1:
The patent uses a thin, flexible diffuser film that provides necessary light diffusion and protection for the LED ribbon while adding minimal weight, maintaining the lightweight advantage while eliminating the harmful effects of exposed LEDs
Solution Approach 2:
The patent employs composite construction combining the LED ribbon, thin diffuser material, and minimal structural support elements to achieve optimal balance between weight, protection, and light diffusion characteristics

AI summary
Practical lighting is the technique of using light sources that are seen within the frame of a shot. Apparatus 10 and 10A is a lightweight, magnetically mounted, light diffusing housing for LED ribbon which is designed to look like a standard fluorescent tube when used as practical lighting. Control wires can be easily and repeatedly removed via screwed terminal housings (10) or connected via industry standard phoenix receptacle (10A) housed discreetly one of its two end caps, providing a solderless connection with either apparatus. The magnets internally installed adhere the apparatus to standard metal fluorescent housings without damage to the installed fixture negating the need of additional mounting rigging hardware.
