Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If traditional metal halide or sodium lamps are used, then high light output is achieved, but high power consumption is required
Solution Approach 1:
The light source is divided into multiple individual LED elements arranged in an array, with each LED contributing to the overall light output. This segmentation allows for efficient energy conversion at the component level while achieving high total illumination through aggregation of multiple low-power elements.
Solution Approach 2:
The invention transitions from traditional lamp technology to LED technology, fundamentally changing the energy conversion parameters. LEDs convert electrical energy to light with significantly higher efficiency, operating at lower power levels while maintaining or exceeding the illumination output of traditional high-power lamps.
2Adaptability or versatility
If a universal retrofit design is implemented, then adaptability to different fixtures is improved, but device complexity increases
Solution Approach 1:
The light source unit is designed with universal mounting features including threaded rods for suspension, bracket mounting options, and adapter interfaces that enable installation in various fixture types including streetlights, area lights, and indoor fixtures. This multi-functionality allows a single design to serve multiple application scenarios.
Solution Approach 2:
The modular construction with separable mounting components and interchangeable adapters allows the core LED array to remain simple while adding complexity only where needed for specific installations. Each mounting option is an independent module that can be attached to the basic unit without redesigning the entire system.
