Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If current lighting systems are used to create decorative lighting effects, then lighting effects can be produced, but the light gradient is not smooth and fails to truthfully reproduce natural phenomena
Solution Approach 1:
The lighting system is segmented into multiple independently controllable LED modules arranged in a linear array. Each module can be individually controlled to emit light of different intensities and colors, allowing precise manipulation of the light gradient across the entire array. This segmentation enables smooth transitions between different lighting zones, accurately reproducing natural phenomena such as sunsets or horizons without the harsh transitions characteristic of conventional lighting systems.
2Adaptability or versatility
If complex arrangements are used to achieve desired lighting effects, then lighting effects can be produced, but the system complexity increases and requires tedious tuning
Solution Approach 1:
The LED module is designed as a universal, multi-functional unit that can produce various lighting effects through electronic control rather than physical reconfiguration. Each module contains LEDs of multiple colors (e.g., red, green, blue) that can be independently controlled to create different colors and intensities. This allows a single standardized module design to achieve diverse lighting effects such as sunsets, horizons, or other natural phenomena, eliminating the need for complex mechanical arrangements or multiple specialized components.
Solution Approach 2:
The lighting system employs dynamic electronic control of LED modules to achieve desired lighting effects. The intensity and color of each LED or LED module can be dynamically adjusted through control signals, allowing real-time manipulation of the light gradient and color distribution. This dynamic control enables versatile lighting effects without requiring complex physical structures, as the effects are achieved through programmable electronic adjustment rather than mechanical complexity.
