Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If traditional fluorescent tube luminaires are replaced with LED-based systems, then energy consumption is reduced, but installation complexity and difficulty increase
Solution Approach 1:
The lighting assembly is divided into separate modular components: reflectors, sidewall parts, and light engine. These segments can be independently manufactured, handled, and installed, reducing installation complexity while maintaining energy efficiency benefits of LED technology
Solution Approach 2:
The lighting assembly is designed with universal mounting features that enable installation in existing fluorescent tube luminaires. The reflectors and sidewall parts can accommodate various light engine configurations, making the system universally applicable across different fixture types while providing LED energy savings
2Adaptability or versatility
If modular lighting assembly components are used, then adaptability and reuse are improved, but device complexity increases
Solution Approach 1:
The assembly is segmented into distinct functional modules (reflectors, sidewall parts, light engine) that can be independently replaced or upgraded. This segmentation enables adaptability for different lighting applications while the standardized interfaces between segments reduce the perceived complexity of assembly
Solution Approach 2:
The light engine is nested within the cavity formed by the reflectors and sidewall parts. This nested configuration allows the compact assembly to adapt to various fixture sizes while reducing the number of separate connection points, thereby simplifying the overall assembly process despite the modular design

AI summary
A lighting assembly adapted to be mounted in a lighting fixture is provided. The lighting assembly comprises comprises a first reflector, a second reflector and at least two sidewall parts, a first fastening arrangement adapted to secure the first reflector to at least one sidewall part, and a second fastening arrangement adapted to secure the second reflector to at least one sidewall part. The first reflector, the second reflector annd the at least two sidewall parts are adapted to be arranged in the lighting fixture and secured to each other such that they define sidewalls of a four-sided cavity. Further, junctions between the first reflector, the second reflector and the at least two sidewall parts are arranged to be at the corners of the four-sided cavity when the first reflector, the second reflector and the at least two sidewall parts are arranged in the lighting fixture. Each one of at least two of the first reflector, the second reflector and the at least two sidewall parts comprises a support surface adapted to support the lighting assembly in the lighting fixture and to be arranged at different sides of the four-sided cavity when the first reflector, the second reflector and the at least two sidewall parts are arranged in the lighting fixture. Further, the light engine is arranged to emit light out of the four-sided cavity. Thereby, a lighting assembly that is easier to install is achieved.
